by
The 1st Basic Cardiac Life Support and Advanced Cardiac Life Support Course were held in Kuala Lumpur General Hospital in 1986. It was jointly organised by the Ministry of Health, Malaysian Society of Anaesthesiologists and National Heart Association in collaboration with the American Heart Association. Since then, a number of changes have been made to both courses to cater to local needs. The Basic Cardiac Life Support Course was renamed Basic Life Support Course and shortened to one day. Similarly the Advanced Cardiac Life Support Course was renamed Advanced Life Support Course and reduced to two days. However, material for the Advanced Cardiac Life Support Course was taken totally from the American Heart Association. With the formation of the Advanced Life Support Subcommittee under the umbrella of National Committee on Resuscitation Training, the Advanced Life Support Training Manual was compiled. I congratulate the Subcommittee for producing the training manual. I hope the participants of the Advanced Cardiac Support Course will find the manual useful and comprehensive. Thank you.

chapter 1
Course Overview
The Advanced Life Support Course aims to train doctors and healthcare providers working in critical care areas in the resuscitation of patients beyond the ABC of resuscitation. The course emphasizes on enhancing your skills in the treatment of arrest patients through active participation in a series of simulated cardiopulmonary cases. These simulations are designed to reinforce important concepts, including The Basic Life Support (BLS) Primary Survey The Advanced Life Support (ALS) Secondary Survey The ALS algorithms Effective resuscitation team dynamics
Course Objectives
Upon completion of this course, you should be able to Manage cardiac arrest until return of spontaneous circulation (ROSC), termination of resuscitation, or transfer of care Demonstrate effective communication as a member or leader of a resuscitation team and recognize the impact of team dynamics on overall team performance
Course Description
The course concentrates on skills both individually and as part of a team. Lectures are short and few. Therefore you are expected to have read the ALS provider training manual before the course. In addition, strong BLS skills are the foundation of ALS. You must have passed the 1-rescuer BLS/ Automated External Defibrillator (AED) course before enrolment into the ALS course. The course programme is as follows:

The BLS Primary Survey
The BLS goal is to support or restore effective oxygenation, ventilation, and circulation until ROSC or until ALS interventions can be initiated. Performance of the actions in the BLS Primary Survey substantially improves a patients chance of survival and a good (or better) neurologic outcome. Before conducting the BLS Primary Survey, you should assess Danger, check patient Responsiveness, Shout for help (activate emergency medical system and get an AED). The BLS Primary Survey is an ABCD approach using a series of sequential assessments. Each assessment is followed by appropriate action(s) if needed. As you assess each step (the patients airway, breathing, circulation, and determine if defibrillation is needed), you stop and perform an action, if necessary, before proceeding to the next assessment step. Assessment is a key component in this approach. For example: Check for responsiveness before shouting for help and open the airway Check breathing before starting chest compressions Attach an AED, then analyze for a shockable rhythm before delivering a shock
assess...then perform appropriate action. Table 1 below shows an overview of BLS Primary Survey. DRS is included before ABCD for completeness.
Remember:
Assess
Action
Wear PPE (gloves, apron, mask) if available Make sure you, the victim and bystanders are safe
- Are there blood spills, sharps, electric wires? - Is the scene dangerous?
Danger
Tap shoulders and Say Hello! Hello! Are you OK? Emergency! Emergency! Call ambulance 999 or bring emergency trolley & defibrillator if available
13
Assess
Action
Airway
Open the airway using non invasive techniques (head tilt-chin lift; jaw thrust without head extension if trauma is suspected) Look for normal breathing in not more than 10s (almost simultaneously when performing head tilt chin lift) Perform high-quality CPR if not breathing or abnormal breathing (gasps) is seen until an AED arrives Provide shocks as indicated Follow each shock immediately with CPR, beginning with chest compressions
Breathing
Circulation
Defibrillation
NB. Make every effort to minimize interruptions in chest compressions. Limit interruptions in chest compressions to no longer than 10s
Avoid:
Prolonged rhythm analysis Taking too long to give breaths to the patient
14
Assess
Action
- Maintain airway patency in unconscious patients by use of head tilt-chin lift, orophyaryngeal airway (OPA) or nasopharyngeal airway (NPA) - Use advanced airways if needed (e.g. LMA or ETT) - - Give supplementary oxygen Assess the adequacy of oxygenation and ventilation by Clinical criteria (colour, chest rise, auscultation) Oxygen saturation Capnometry or capnography
Airway
- Are oxygenation and ventilation adequate? - Is an advanced airway indicated? - Is proper placement of airway device confirmed? - Is tube secure and placement reconfirmed requently? - Are exhaled CO2 and oxyhemoglobin saturation monitored?
Breathing
The benefit of advanced airway placement is weighed against the adverse effects of interrupting chest compressions. If bag-mask ventilation is adequate, insertion of an advanced airway may be deferred until the patient fails to respond to initial CPR and defibrillation or until ROSC. If advanced airway devices are used: - Confirm proper integration of CPR and ventilation - Confirm proper placement of advanced airway devices by Clinical criteria (colour, chest rise, auscultation) Capnometry or capnography - Secure the device to prevent dislodgment - Continue exhaled CO2 measurement
- - - -
Circulation
What was the initial cardiac rhythm? What is the current cardiac rhythm? Have you established access for drug and fluid? Does the patient need volume (fluid) for resuscitation? Are medications needed for rhythm or blood pressure?
- Obtain IV / IO access - Attach ECG leads and monitor for arrhythmias or cardiac arrest rhythms (eg VF, pulseless VT, asystole, and PEA) - Give appropriate drugs to manage rhythm (e.g. amiodarone, lidocaine, atropine, magnesium) and blood pressure (e.g. adrenaline, vasopressin, and dopamine) - Give IV / IO fluids if needed
- Why did this patient develop cardiac arrest? - Why is the patient still in arrest? - Can we identify a reversible cause of this arrest?
Differential Diagnosis
Search for, find and treat reversible causes (i.e. definitive care). Look for 5H and 5T causes. 5H: Hypoxia, Hydrogen ion, Hypothermia, Hypovolemia, Hypo/hyperkalemia. 5T: Tamponade (cardiac), Tension pneumothorax, Thrombosis (pulmonary or coronary), Toxins

Roles
Team Leader Team Member
Team Dynamics
Organizes the group, monitors individual performance of team members, backs up team members, models excellent team behavior, trains and coaches, facilitates understanding and focuses on comprehensive patient care.
Must be proficient to perform skills within their scope of practice. They are clear about their role assignment, prepared to fulfill the role responsibilities, well practiced in resuscitation skills, knowledgeable about the algorithms and committed to success.
16
Knowledge Sharing A critical component of effective team performance is information sharing. The team leader can ask for suggestions when the resuscitation efforts seem to be ineffective. Constructive Intervention During a code, a team leader or member may need to intervene if an action is about to occur at an inappropriate time. The person recording the event may suggest that adrenaline be given as the next drug because it has been 5 minutes since the last dose. All suggestions for a different intervention or action should be done tactfully. Reevaluation and Summarizing An essential role of the team leader is monitoring and reevaluation of the status of the patient, interventions that have been done and assessment findings. Mutual Respect The best teams are composed of members who share a mutual respect for each other and work together in a collegial, supportive manner. All team members should leave their egos at the door.

Overview of Airway Management
Airway Management
The support of ventilation and oxygenation during CPR and the peri-arrest period are still important. The purpose of ventilation during CPR is to maintain adequate oxygenation and sufficient elimination of carbon dioxide. Airway obstruction by the tongue or any other foreign body must be excluded before the purpose of ventilation can be achieved. It is also important to note that both systemic and pulmonary circulation are reduced markedly during cardiac arrest so that the normal ventilation perfusion relationships can be maintained with minute ventilation which is much lower than normal. Empirical use of 100% oxygen during resuscitation from cardiac arrest is reasonable.

18
Nasal Cannula
Consists of 2 prongs Every 1L/minute increase in O2 flow rate increase in FiO2 by 4% Usually 1-6L/minute O2 given Do not use more than 6L/minute O2 as this does not increase oxygenation much, yet dries up nasal passages and is uncomfortable to patient O2 concentration depends on: - O2 supply flow rate - Pattern of ventilation - Patient inspiratory flow rate
Venturi Mask
Based on Bernoullie principle - O2 is passed through a narrowed orifice and this creates a high-velocity stream of gas. This high-velocity jet stream generates a shearing force known as viscous drag that pulls room air into the mask through the entrainment ports on the mask. Gives desired concentration of oxygen to patient (24% to 60%) Good for patient with chronic obstructive airway disease
19
Nasopharyngeal Airway
An uncuffed tube made of soft rubber or plastic Used in patient where mouth opening is difficult More tolerable by semi-comatose patient Used with caution in patient with base of skull fracture or with ENT bleeding May cause airway bleeding in up to 30% patients Various sizes (size indicates internal diameter) - The appropriate size is measured from tip of the nose to tragus of the ear

Face Mask
21
The bag-mask device consists of a self-inflating bag and a non-rebreathing valve - Can be used with a face mask or an advanced airway eg Laryngeal mask airway (LMA) or endotracheal tube (ETT) - Provides positive pressure ventilation - Cannot be used to allow spontaneous breathing The provider should use an adult (1 to 2 L) bag and deliver just enough volume to produce an obvious chest rise Bag-mask ventilation can produce gastric inflation with complications, including regurgitation and aspiration Two ways of holding the bag-mask device on the face for adequate ventilation:
Advanced Airways
Bag-mask ventilation is not suitable for prolonged periods of ventilation as it also inflates the stomach. Therefore, ALS providers should be trained in the use of an advanced airway (supraglottic airways or ETT). However, the provider should weigh the need for minimally interrupted chest compressions against the need for insertion of a supraglottic airway or an ETT.
Supraglottic Airways
Supraglottic airways are devices designed to maintain an open airway and facilitate ventilation. Insertion of a supraglottic airway does not require visualization of vocal cord and so it is possible to insert without interrupting chest compression during resuscitation. A number of supraglottic airways are available: Laryngeal mask airway (LMA), combitube and laryngeal tube. The LMA provides a more secure and reliable means of ventilation and is widely used in clinical practice.
22
Apeture Bars
Cuff
Versions of LMA
Many different versions of LMA since its invention: LMA Classic - original reusable design LMA Unique - disposable version for use in emergency and prehospital setting LMA Fastrach (Intubating LMA) - as a conduit for intubation LMA Flexible - soft tubing and not for use in emergency setting LMA Proseal - additional channel for suctioning of gastric contents LMA Supreme - similar to Proseal but with built-in bite block LMA Ctrach - built-in fi ber-optics with a video screen
23
Size of LMA
Size 1 Size 1.5 Size 2 Size 2.5 Size 3 Size 4 Size 5
Weight of patient
< 5 kg 5 to 10 kg 10 to 20 kg 20 to 30 kg 30 to 50 kg or small adult 50 to 70 kg (adult) > 70 kg (large adult)
Insertion of LMA
Before any attempt to insert an LMA, the following equipment has to be prepared: Personal protective equipment - mask, eye shield/goggle, gloves Appropriate size LMA Syringe with appropriate volume (10, 20 or 50 ml) for LMA cuff infl ation Water soluble lubricant Ventilation equipment Tape or other device(s) to secure LMA Stethoscope
The following are the steps necessary for successful insertion of LMA: Step 1: Size selection - as per Recommended Size Guidelines
24
Step 2: Examination of LMA Inspect surface of LMA for damage, including cuts, tears, or scratches - Do not use the LMA if the airway tube is damaged in any way Inspect interior of LMA airway tube to ensure that it is free from blockage or loose particles - Any particles present in the airway tube should be removed as patient may inhale them after insertion Inflate cuff to ensure that it does not leak Deflate cuff to ensure that it maintains a vacuum
Step 3: Check inflation and deflation of cuff Inflate cuff with the recommended volume of air Slowly deflate cuff to form a smooth flat wedge shape which will pass easily around the back of the tongue and behind the epiglottis
Step 4: Lubrication of LMA Cuff/Mask Use a water soluble lubricant to lubricate Only lubricate LMA cuff/mask just prior to insertion Only lubricate back of LMA cuff/mask thoroughly Avoid excessive lubricants on anterior surface or in the bowl of cuff/mask as inhalation of the lubricant following placement may result in coughing or obstruction
Step 5: Position head for insertion LMA can be inserted even if the head is in the neutral position as long as the mouth opening is adequate Avoid LMA fold over: - Assistant pulls the lower jaw downwards - Visualize the posterior oral cavity - Ensure that LMA is not folding over in the cavity as it is inserted
25
With the head tilt and the neck flexed, insert the cuff of LMA into the oral cavity; direction of force goes against the hard palate
To facilitate introduction of LMA into the oral cavity, gently press the middle finger down onto the jaw
The index finger pushes LMA in a cranial direction following the contours of the hard and soft palates
26
Maintaining pressure with finger on LMA in the cranial direction, advance LMA until definite resistance is felt at the base of the hypopharynx: note flexion of the wrist
Gently maintain cranial pressure with non-dominant hand while removing index finger
Bite Block
Tape
To allow LMA to seat optimally, inflate without holding LMA Inflate cuff with just enough air to obtain a seal - this should correspond to intracuff pressures around 60 cm H2O; do not over-inflate
Tape the bite-block and LMA airway tube downwards against the chin
27
Finally connect to bag-mask or ventilator and look for chest rise Confirm equal breath sounds over both lung fields & absence of ventilatory sounds over epigastrium
Laryngoscope
Consists of handle (which contains a battery power source) and blade 2 types of blades: Macintosh blade (curved) for adults Miller blade (straight) for newborn and infants Make sure that the light on the blade works and is bright when lit up
28
Endotracheal Tube
Typical modern ETT has the following features: Marked with - Size with internal diameter in mm; external diameter in smaller lettering - Z-79 which denotes that the material has been implantation tested in rabbit muscle for tissue compatibility - Distance from the tip of ETT at intervals along ETTs length. Most plastic tubes are longer than is usually required and may be cut to size - Other markings which may refer to the manufacturer, the trade name of the type of ETT, and whether it is intended for oral or nasal use - A radio-opaque line to aid detection of ETT on chest X-rays Curved with a left-facing bevel at the distal. A hole in the wall opposite the bevel (Murphy eye) allows ventilation should the end become obstructed by the tracheal wall or mucus or secretions Attached to a ETT connector at the proximal end May bear a cuff near the distal end, with a pilot balloon running towards the proximal end. The cuff is of high volume and low pressure type to reduce pressure on the tracheal mucosa Choosing The Correct Size ETT

3A: Laryngoscopy
Use left hand to hold laryngoscope Enter at right side of mouth and push tongue towards left side Move the laryngoscope blade toward midline and advance to the base of tongue. Advance the blade to the vallecula if the curved blade is used or to just beyond tip of epiglottis if the straight blade is used Lift upward and forward to bring the larynx and vocal cords into view as indicated by the arrow in the diagram above. The direction of force necessary to lift the mandible and tongue is 45 degrees. Do not use the teeth as a fulcrum or a lever
Time taken for laryngoscopy and insertion of ETT should not be more than 30 seconds
Step 4: Confi rm correct position of ETT Observe colour of patient Visualise chest rise with delivery of fi rst manual breath Detect vapour in ETT 5 points auscultation for breath sounds (auscultate epigastrium, anterior chest at bilateral mid-clavicular lines and thorax at bilateral mid-axillary lines) Detect end-tidal CO2 with capnography or CO2 detector device
31
Step 6: Ventilate with a tidal volume of 6-8 ml/kg (visible chest rise) at a rate of 8-10 breath per minute
Use of Devices to Confirm Correct ETT Placement Via Detection of CO2 Production
Detection of end-tidal CO2 during resuscitation: Confirms ETT placement; note that EtCO2 detection will not differentiate between tracheal and endobronchial tube placement. Careful auscultation is essential Correlates with cardiac index Assesses adequacy of ventilation Indicates quality of CPR Signifies ROSC Carries prognostic value for survival post cardiac arrest
There are a number of CO2 detector devices available: i) Esophageal detector device ii) End-tidal CO2 (EtCO2) detector device iii) Disposable calorimetric EtCO2 detector iv) Continuous digital EtCO2 detector device v) Continuous waveform EtCO2 capnography

33
Tracheobronchial Suctioning
Suction Catheter
Size (FG) = ETT internal diameter (mm) x 3/2 or outer diameter should not exceed 1/2 to 2/3 ETT internal diameter Minimal trauma to mucosa with molded ends and side holes Long enough to pass through tip of ETT Minimal friction resistance during insertion through ETT Sterile and disposable
Suction Pressure
100 to-120mmHg (adults) 80 to-100mmHg (children) 60 to-80 mmHg (infants)
Always preoxygenate with 100% O2 for 3-5 minutes to reduce risk of hypoxia and arrhythmias Using sterile technique, the suction catheter is inserted without closing the side opening in the proximal end of the catheter The suction catheter is advanced to the desired location which is approximately at the level of the carina where trachea bifurcates Suction is applied intermittently by closing the side opening while the catheter is withdrawn with a rotating motion Limit duration of suctioning to 10-15 seconds. If arrhythmias occur, immediately discontinue suctioning and manually bag patient with O2 Prior to repeating the procedure, patient should be ventilated with 100% O2 for about 30 seconds.
Point to note:
In patient with elevated intracranial pressure (e.g. head injury), temporary hyperventilation before and after suctioning may be indicated

chapter 5
What is Defibrillation?
The passage of an electrical current across the myocardium to depolarise a critical mass of myocardium and enable restoration of coordinated electrical activity An electrophysiological event that occurs 30-50 ms after shock delivery-the heart is stunned and hopefully the sino-atrial (SA) node will take over Aims to restore sinus rhythm Typically defined as the termination of ventricular fibrillation (VF) for at least 5 after the shock. Shock success using this definition does not equal to resuscitation outcome Only for VF or pulseless ventricular tachycardia (VT) where a single shock is given followed immediately by chest compression without any pulse check or rhythm reanalysis after a shock
For every minute that passes between collapse and defibrillation, survival rates from witnessed VF SCA decrease 7% to 10% if no CPR is provided. When bystander CPR is provided, the decrease in survival rates is more gradual and averages 3% to 4% per minute from collapse to defibrillation. CPR prolongs VF, delays the onset of asystole and extends the window of time during which defibrillation can occur. Basic CPR alone, however, is unlikely to terminate VF and restore a perfusing rhythm.
Defibrillators
Modern defibrillators are classified according to 2 types of waveforms: monophasic and biphasic. Monophasic waveform defibrillators were introduced first, but biphasic waveforms are used in almost all Automated External Defibrillators (AEDs) and some manual defibrillators sold today. Energy levels vary by type of device and manufacturer.
35
Electric/Paddle force
8kg in adult 5kg in 1-8years when using adult paddles
Transthoracic Impedance
Use gel pads or electrode paddles or self-adhesive pads to reduce transthoracic impedance. The average adult human impedance is 70 to 80 . When transthoracic impedance is too high, a low-energy shock will not generate sufficient current to achieve defibrillation
Electrode/Paddle Placement
Can be at antero-lateral, antero-posterior, anterior-left infrascapular and anterior-right infrascapular locations on the chest/back. All these 4 positions are equally effective. For ease of placement and education, anterolateral is a reasonable default electrode placement. Ensure that the paddle and gel or pads are in full contact with the skin Special considerations:
36
Breasts - Place lateral pads/paddles under breast tissue - Move pendulous breasts gently out of the way Wet Chest - Briskly wipe the chest dry before attaching electrode pads and attempting defibrillation Hirsutism - Shave hirsute males prior to application of pads - Remove excess chest hair by briskly removing an electrode pad (which will remove some hair) or by rapidly shaving the chest in that area Automated Implanted Cardioverter Defibrillator - Avoid placing the pads or paddles over the device as there is a potential for pacemaker or ICD to malfunction after defibrillation when the pads are in close proximity to the device - Use antero-posterior and antero-lateral locations
Presence of Transdermal Medication Patch (eg patch containing nitroglycerin, nicotine,analgesics, hormone replacement, anti-hypertensives) - Do not place electrodes over transdermal medication patch which may block delivery of energy from the electrode pad to the heart and may cause small burns to the skin - Remove medication patch and wipe the area before attaching the electrode pad if defibrillation is needed
Safety Issues
Fire
Ignited by sparks from poorly applied defibrillator paddles in the presence of an oxygen-enriched atmosphere Avoid defibrillation in an oxygen-enriched atmosphere Use self-adhesive defibrillation pads Ensure good padchest-wall contact If manual paddles are used, gel pads are preferable to electrode pastes and gels because the pastes and gels can spread between the 2 paddles, creating the potential for a spark
Accidental Electrocution
Charge paddles after being placed on patients chest rather than prior to being taken out from the defibrillator Ensure that none of the rescuer team members is in contact with patient/victim/resuscitation trolley prior to defibrillator discharge
37
Make sure that no oxygen is flowing across the patients chest or openly across the electrode pads Carry out the above steps quickly to minimize the time from the last compression to shock delivery
An Example:
One I Clear
(Check to make sure you have no contact with the patient, the trolley or other equipment)
(Check to make sure that no one is touching the patient. No one includes providers performing chest compressions, starting IVs, inserting catheters, or performing ventilation and airway maintenance)
(Perform a visual check to make sure no one has contact with the patient or trolley)

Attach electrodes to patients chest Turn defibrillator on select leads Analyse the rhythm? shockable Apply coupling agent or pads to patients chest Select energy level Apply paddles to chest Charge the paddles The Clear chant Check monitor again Discharge shock and return the paddles to the machine
38
Synchronized Cardioversion
A shock delivery that is timed (synchronized) with the QRS complex Avoids shock delivery during the relative refractory portion of the cardiac cycle when a shock could produce VF
Unstable Monomorphic (Regular) VT With a Pulse - Treat with monophasic or biphasic waveform cardioversion (synchronized) at an initial energy dose of 100J. If the initial shock fails, increase the dose in a stepwise fashion.
39
Synchronized cardioversion is preferred for treatment of an organized ventricular rhythm. However, for some arrhythmias, the many QRS configurations and irregular rates that comprise polymorphic ventricular tachycardia make it difficult or impossible to reliably synchronize to a QRS complex. If there is any doubt whether monomorphic or polymorphic VT is present in the unstable patient, do not delay shock delivery to perform detailed rhythm analysis-provide high energy unsynchronized shocks (i.e. defibrillation doses, 360J monophasic or 120-200J biphasic).
Points to know:
Pacing
Not recommended for patients in asystolic cardiac arrest as it is not effective and may delay or interrupt the delivery of chest compressions It is reasonable for healthcare providers to be prepared to initiate pacing in patients who do not respond to atropine (or second-line drugs if these do not delay definitive management). Immediate pacing might be considered if the patient is severely symptomatic. If the patient does not respond to drugs or transcutaneous pacing, transvenous pacing is probably indicated.
Summary
The recommendations for electrical therapies described in this section are designed to improve survival from SCA and life threatening arrhythmias. Whenever defibrillation is attempted, rescuers must coordinate high-quality CPR with defibrillation to minimize interruptions in chest compressions and to ensure immediate resumption of chest compressions after shock delivery.

Drugs in Resuscitation
Introduction
Naturally occurring cathecholamines with alpha and beta effects Administration in cardiac arrest will cause intense vasoconstriction (alpha adrenergic action) and divert cardiac output to vital organ such as brain and heart Can improve ROSC although no difference in survival (Retrospective study) Facilitate defibrillation by improving myocardial blood flow during CPR
Dose and Administration For Cardiac Arrest IV/IO: 1mg (10ml of 1:10000 solution), administered every 3-5minutes followed by 20ml flush Higher dose: Specific indication only such as beta blocker or calcium channel blocker overdose. Can use up to 0.2mg/kg Infusion: Infusion rate of 1g/min titrated to effects (typically 2-10g/minute) If IV/IO is difficult to establish, adrenaline can be given through ETT at dose of 2-2.5mg For Profound Bradycardia or Hypotension Infusion at 2-10g/minute, titrated to response
Indications
Cardiac arrest: The first drug to be used in cardiac arrest of whatever cause Symptomatic bradycardia: Can be considered after atropine as an alternative infusion to dopamine Severe hypotension Anaphylaxis
Atropine
Introduction
An anticholinergic agent Antagonises the action of the parasympathetic neurotransmitter acetylcholine at muscarinic receptors. Therefore, it blocks the effect of the vagus nerve on both the sino-atrial (SA) node and the atrio-ventricular (AV) node, increasing sinus automaticity and facilitating AV node conduction Dose and Administration The recommended dose for bradycardia is 0.5mg IV every 3 to 5 minutes to a max total dose of 3mg Doses of atropine sulfate of < 0.5mg may paradoxically result in further slowing of the heart rate Atropine administration should not delay external pacing for patients with poor perfusion
50
Introduction
First line drug for symptomatic Bradycardia Organophosphate poisoning
Dose and Administration Use atropine cautiously in the presence of acute coronary ischemia or MI; increased heart rate may worsen ischemia or increase infarction size. Will not be effective in infranodal (type II) AV block and new third-degree block with wide QRS complexes
Adenosine
Introduction
Naturally occurring purine nucleotide Slows transmission across AV node but has little effect on other myocardial cells or conduction pathways Highly effective for terminating paroxysmal SVT with re-entrant circuits that include AV node (AVNRT) In other narrow-complex tachycardias, adenosine will reveal the underlying atrial rhythms by slowing the ventricular response Dose and Administration Give 6 mg adenosine as a rapid IV push through a large (e.g. antecubital) vein followed by a 20mL saline flush. If unsuccessful, this can be followed with up to two doses each of 12mg every 1-2 minutes
Indications
First drug for most form of stable narrowcomplex PSVT Effective in terminating stable narrowcomplex PSVT due to reentry involving AV node or sinus node May be considered for narrow-complex reentry tachycardia while preparing for cardioversion
Amiodarone
Introduction
An antiarrhythmic with complex pharmacokinetics and pharmacodynamics Act on sodium, potassium and calcium channels Poses alpha and beta-adrenergic blocking properties. Dose and Administration For refractory VF/pulseless VT - IV/IO 300mg bolus (dilute in 20mL Dextrose 5% solution) - Can repeat in 3-5minutes, 150 mg
51
A membrane-stabilising anti-arrhythmic drug that increases the duration of the action potential and refractory period in atrial and ventricular myocardium A mild negative inotropic action Causes peripheral vasodilation through non-competitive alpha blocking effects. Atrioventricular conduction is slowed, and a similar effect is seen with accessory pathways.
For unstable tachyarrhythmias where cardioversion fails 3X, 300mg IV over 1020 minutes For stable tachyarrhythmias, 300mg IV over 20-60 minutes For Maintenance infusion: 900 mg IV over 24h g
Indications
Refractory pulseless VT/VF (between the third and fourth shock when refractory to defibrillatory shock and vasopressor) Stable and unstable tachyarrhythmias
Calcium
Introduction
Essential for nerve and muscle activity Plays a vital role in the cellular mechanism underlying myocardial contraction No data supporting any beneficial action for calcium after cardiac arrest Some studies have suggested a possible adverse effect when given routinely during cardiac arrest (all rhythms) Dose and Administration The initial dose of 10 ml 10% calcium chloride (6.8 mmol Ca2+) may be repeated if necessary
Indications
Only in Pulseless Electrical Activity caused by hyperkalaemia overdose of calcium hypocalcaemia channel blocker
Lignocaine
Introduction
Act as a calcium channel blocker Dose and Administration Cardiac arrest from VT/VF Initial dose: 1-1.5mg/kg IV or IO For refractory VF: may give additional dose 0.5-0.75mg/kg and repeat 5-10 minutes up to 3 times or maximal dose of 3mg/kg
Indications
Alternative to amiodarone in cardiac arrest from VT/VF Stable monomorphic VT with preserved ventricular function
52
Dopamine
Introduction
A chemical precursor of noradrenaline that stimulates both alpha and beta adrenergic receptors In addition, there are receptors specific for dopamine (DA1, DA2 dopaminergic receptors) Stimulates the heart through both alpa and betareceptors Both a potent adrenergic receptor agonist and a strong peripheral dopamine receptor agonist. These effects are dose dependent. Dose and Administration Usual infusion rate is 2-20g/kg/minute and dose titrated according to response
Indications
Second-line drug for symptomatic bradycardia Use for hypotension (systolic BP < 70 to 100 mm Hg) with signs and symptoms of shock
Magnesium
Introduction
An electrolye important for maintaining membrane stability Hypomagnesemia can cause myocardial hyperexcitability especially in the presence of hypokalemia or digoxin Given for hypomagnesemia and Torsades de pointes Insufficient evidence to recommend for or against its routine use in cardiac arrest Dose and Administration Cardiac arrest due to Torsades de pointes or hypomagnesemia: 1-2g diluted in 10 mL D5% to be given over 5-20 minute Torsades de pointes with pulse or AMI with hypomagnesemia: Loading dose of 1-2g mixed with 50 mL D5% over 5-60 minute, followed with 0.5 to 1g/hour (titrate to control Torsades)
Indications
Recommended in cardiac arrest only if Torsades de pointes or if hypomagnesemia is present Life threatening ventricular arrhythmias due to digitalis toxicity
53
Vasopressin
Introduction
A non-adrenergic peripheral vasoconstrictor Causes coronary and renal vasoconstriction No difference in outcome (ROSC, survival to discharge or neurological outcome) with vasopressin (40 units IV) versus adrenaline 1 mg as a first line vasopressor in cardiac arrest (three RCT and meta-analysis of the trials) Dose and Administration For cardiac arrest 40 units IV/IO may replace 1st or 2nd dose of Adrenaline
Indications
As an alternative pressor to adrenaline in the treatment of refractory VF or pulseless VT Maybe useful as alternative to adrenaline in PEA and asystole
Sodium Bicarbonate
Introduction
A strong alkaline agent with high sodium and bicarbonate load Not recommended for routine use in cardiac arrest Dose and Administration 1 mEq/kg IV bolus
Indications
Known prexisting hyperkalemia Known preexisting bicarbonate responsive acidosis e.g. : aspirin overdose, diabetic ketoacidosis, tricyclic antidepressant or cocaine Prolonged resuscitation with effective ventilation. Upon return of spontaneous circulation after long arrest interval Not useful nor effective in hypercarbic acidosis (e.g. cardiac arrest or CPR) without tracheal intubation

Post Resuscitation Care
Post resuscitation care starts when there is return of spontaneous circulation (ROSC). The chances of achieving ROSC are greatly enhanced when: The arrest is witnessed The underlying arrhythmia is VF or pulseless VT Successful defibrillation is achieved in 2-3 minutes and not longer than 8 minutes High quality CPR started and continued
It emphasises the following measures to improve neurological outcome: Avoid hyperoxaemia after ROSC; titrate oxygen to SaO2 94-96% Glucose control to treat hyperglycaemia (>10mmol/L) and avoid hypoglycaemia Seizure control Maintenance of cerebral perfusion Therapeutic hypothermia
A comprehensive post resuscitation treatment protocol for the management of patients after cardiac arrest includes: 1. Airway Ensure that the airway is open, oxygenation and perfusion are adequate Titrate oxygen to SaO2 94-96% Consider advanced airway support if not instituted Position the unintubated patient in the recovery position to prevent aspiration 2. Hemodynamics/Circulation Always assess the haemodynamic status of the patient Monitor vital signs every 5-15 minutes Report patients progress at intermittent intervals Report any deterioration or drastic changes immediately When resuscitation is prolonged, hypotension is common following ROSC. Should hypotension persist, dopamine titrated to maintain a systolic blood pressure of 90mmHg is the agent of choice 3. Therapeutic Hypothermia Cool patient to 32-340C for 12-24 hours.
60
4. Neurology Status Assess patients ability to respond to verbal or painful stimuli Check the motor response to detect any motor deficit Check the pupils size and reaction 5. Drug Infusion Consider anti-arrhythmics that have been effective during the resuscitation as infusions Use infusion pumps to ensure accurate delivery Maintain an accurate record of all fluids given 6. Correct Abnormalities Actively search and correct underlying abnormalities which may lead to arrest Common abnormalities that may require correction after the arrest include electrolyte imbalances, hypoxaemia and acidosis Correct glucose level > 10.0mmol/l and avoid hypoglycaemia 7. Transfer to Intensive Care Unit (ICU) or Coronary Care Unit (CCU) Make immediate arrangement to transfer the patient to ICU or CCU if the patients condition remains critical Prior to transfer, ensure the patients condition is stabilised and patient fit for transfer 8. Documentation of the Resuscitation The resuscitation record is an essential component of any resuscitation effort It provides documentation of the life support procedures that were performed The record allows us to reconstruct the sequence of events with correlation of interventions and responses during the resuscitation The record also allows the evaluation of appropriateness of care and facilities Such documentation allows the evaluation of appropriateness of care and facilities the prospective collection of data for measuring the outcome and effects of training Relatives must always be kept informed
Summary
After a successful resuscitation, it is crucial that the patients airway, breathing and circulation are secured and stabilized. Haemodynamic and neurological states are closely monitored before and during transfer to ICU or CCU. Relatives must always be kept informed.

Ethical principles
When caring for those who need CPR, healthcare providers must consider ethical, legal and cultural factors. The decision to initiate or continue resuscitative effort should be guided by knowledge, individual patient or surrogate preferences, local and legal requirements. There are 5 important aspects of ethical principles that govern the decision for resuscitation: 1) Autonomy: Right of patient to accept or refuse therapy. Applied to those who has decision-making capacity unless otherwise as declared by a court of law 2) Beneficence: Benefit provided to patient while balancing risks and benefits
3) Non maleficence: Doing no harm or further harm 4) Justice: Equal distribution of limited health resources and if resuscitation is provided it should be available to all who will benefit from it within the available resources 5) Dignity and Honesty: Patient should be treated with dignity. There must be honesty in revealing information in the best interest of the patient
62
This is an important aspect in deciding whether to start or withhold CPR. It is a legal binding document in the United States and can be either verbal or written, based on conversations, written directives, living wills or from a durable power of attorney. It is important to note that the court of law accepts written advanced directives more than recollections of conversations. Principles of futility Medical futility occurs when an intervention is unlikely to benefit the patient. It is also defined when an intervention fails to achieve patients intended quality goals or the physicians physiological goals. Discontinuation of resuscitative efforts or withholding resuscitation should be considered in such situations. However, if the prognosis is in doubt or uncertain, a trial of treatment should be considered until adequate information is gathered to determine the expected clinical course or the likelihood of survival. Following are instances whereby CPR efforts should be reconsidered: 1) When to stop CPR - Return of spontaneous circulation - Exhaustion - Obvious signs of death - Decision by the caring physician 2) When not to start CPR - Presence of an Advanced Directive by the patient or surrogate decision maker - Valid DNAR by attending physician - Obvious signs of death - Injuries incompatible with life
