ALS Subcommittee 2010
3. DRUGS USED IN RESUSCITATION
• Adrenaline
• Vasopressin
• Atropine
• Amiodarone
• Lignocaine
• Adenosine
• Dopamine
ALS Subcommittee 2010
4. ACCESS TO DRUG ADMINISTRATION
• Intravenous
Peripheral or central
• Intra-osseous
• Intra-tracheal
– Larger dose
– Only if intravenous and intraosseous not
available ALS Subcommittee 2010
5. TECHNIQUE FOR IV DRUG
ADMINISTRATION
• Use upper extremity veins
• Keep the access site elevated
• Each IV drug administration to be followed by
20-30mls bolus of normal saline
• The cannula should be as large as possible
• Use normal saline as the fluid of resuscitation
ALS Subcommittee 2010
6. TECHNIQUE FOR ENDOTRACHEAL
DRUG ADMINISTRATION
• Dilute the drug in 10 ml saline
• Thread a long catheter through the ETT
• Stop chest compressions
• Inject the drug through the catheter
• Follow with 3-4 manual lung inflations
• Dosage: 2-2.5x the recommended IV dose
ALS Subcommittee 2010
7. INTRAOSSEOUS
• Available for adult usage
• Site: Iliac crest, sternum
• As effective as intravenous line for resuscitation
ALS Subcommittee 2010
10. ADRENALINE
• Routes of administration:-
› IV push OR Intraosseus 1 mg
Infusion (3mg in 50 mls N/S at 1ml/hr
=1ug/min), titrate accordingly
› ETT (2-2.5X IV dose)
ALS Subcommittee 2010
11. ADRENALINE ---- ACTIONS
• increases contractile force of the heart thus
increasing cardiac output
• increases conduction of SA node, AV node and
ventricle thus increasing heart rate
• increases systemic vascular resistance through
peripheral vasoconstriction thus increasing
perfusion pressure
ALS Subcommittee 2010
12. ADRENALINE ---- SIDE-EFFECTS
• Ventricular irritability
– tachyarrthymias
• ↑ Myocardial Oxygen demand
- risk of ischaemia and MI
• Cerebrovascular event
ALS Subcommittee 2010
13. VASOPRESSIN
• A naturally occurring hormone
• At high doses of 40 units (recommended dosage
during resuscitation)
– shunting of blood to heart and brain
– intense vasoconstriction
– may not increase myocardial oxygen demand
-- unlike adrenaline
ALS Subcommittee 2010
14. VASOPRESSIN
• Indications for use
– Considered as an alternative to adrenaline for
shock due to refractory VF, asystole and PEA
– Used as a single bolus 40 units IV to replace 1st
or 2nd dose of adrenaline
– As a hemodynamic support in septic shock
ALS Subcommittee 2010
15. ATROPINE
• Anticholinergic (parasympatholytic)
– inhibits effect of acetylcholine on SA and AV
node
– increases SA node and AV node conduction
velocity
– decreases effective refractory period AV node
• Increases heart rate and cardiac output
ALS Subcommittee 2010
19. AMIODARONE
• Has characteristics of all 4 antiarrhythmic drug
classes
– affect sodium, potassium and calcium channel
– alpha and beta blocking properties
• Used in BOTH supraventricular and ventricular tachyarrthymias
– Refractory VT/VF
– Stable monomorphic or polymorphic VT
– PSVTs, atrial tachycardia, atrial fibrillation
– Wide complex tachycardia of uncertain origin
– Pre-excited atrial arrhythmia
ALS Subcommittee 2010
20. AMIODARONE
• VF, pulseless VT and refractory VT/VF
– Drug of Choice
• IV bolus dose 300 mg
• repeat IV bolus 150 mg in 3-5 mins
followed by IV Infusion 900 mg over 24h
• Other arrhythmias
› IV Infusion 150 mg over 10 min
ď‚–followed by IV infusion 900 mg over 24h
ALS Subcommittee 2010
22. LIGNOCAINE ---- ACTIONS
• Raises fibrillatory threshold
• enhances the effect of DC shock
• Suppresses automaticity and shortens effective
refractory period and action potential duration
• slows down heart rate
• Inhibits reentry mechanism – halts arrhythmias
ALS Subcommittee 2010
23. LIGNOCAINE
• Routes of administration:-
– IV push (1.0 to 1.5 mg/kg)
Additional 0.5-0.75 mg/kg
Max: 3 mg/kg
Infusion 1 gm Lignocaine in 500 ml N/S
30 to 120 ml/hr (1 – 4 mg/min)
– ETT (2-2.5X IV dose)
ALS Subcommittee 2010
25. ADENOSINE
• A short acting agent that depresses SA node and
AV node function
• Used in narrow complex supraventricular
tachycardia
• Half life : 5 seconds
• Initial dose of 6 mg rapid IV push (may be
repeated at 12 mg ) ALS Subcommittee 2010
26. ADENOSINE - SIDE-EFFECTS
• Transient bradycardia or even ASYSTOLE
• Hypotension
• Chest pain
• Dyspnoea
• Bronchospasm (caution in asthma )
• Transient flushing
ALS Subcommittee 2010
27. DOPAMINE
Indications:
• cardiogenic shock
• septicaemic shock
• neurogenic shock
• anaphylactic shock
• hypovolaemic shock only after fluid resuscitation
has failed to raise BP
ALS Subcommittee 2010
31. SODIUM BICARBONATE
• A significant sodium load
• 8.4% solution is hypertonic => arterial
vasodilatation and hypotension
• Extravasation => tissue necrosis
• Not to be injected via same IV line as
catecholamines and calcium ALS Subcommittee 2010
32. SODIUM BICARBONATE
• only beneficial in hyperkalaemia
• probably beneficial in
- bicarbonate responsive acidosis
• possibly beneficial in
- protracted cardiac arrest with effective
ventilation
- postresuscitation acidosis with effective
ventilation ALS Subcommittee 2010
