4. Adenosine
Dose and preparation
|
Preparation (1ml=3 mg) |
|
Dose ● 6 mg dose followed by a 20 ml NS flush for rapid infusion using 3-way stopcock [due to its short half-life], Second dose of 12 mg using the same procedure and third dose of 12-18 mg using the same procedure. (via peripheral line). ● Initial dose should be reduced to 3 mg with subsequent doses of 6mg, then 9 mg if needed. (via central line). |
5. Lignocaine
Dose and preparation
|
2% lidocaine= 20 mg/ml. |
|
1-1.5 mg/kg slow IV bolus over 2-3 minutes (Undiluted). |
|
May repeat doses of 0.5-0.75 mg/kg in 5-10 minutes up to 3 mg/kg total if refractory Ventricular Fibrillation or pulseless Ventricular Tachycardia. |
|
Continuous infusion: 1-4 mg/min IV after return of perfusion |
|
Administer 0.5 mg/kg bolus and reassess infusion if arrhythmia reappears during constant infusion |
6. Isoprenaline
Dose and preparation
|
1ml (2mg) Isoprenaline + 49ml 5% dextrose= 50 ml (which is equivalent to 40 mcg per ml). |
|
Infusion rate = 1-10 mcg/min. |
|
Consider titrating up in steps of 1microgram/min at intervals of 2-3 minutes. |
|
Do NOT use Sodium Chloride 0.9% as diluent. |
7. Sodium Bicarbonate
Dose and preparation
|
1 ampoule of 7.5% sodium bicarbonate =10 ml=8.92 mEq (rounded to 10 for practical purposes). |
|
Metabolic acidosis; Consider bicarbonate therapy in patients with either a pH of <7.1 or in patients with severe acute kidney injury and a pH of ≤7.2. |
|
Intermittent therapy ● 89.2 mEq (100 ml of 7.5% sodium bicarbonate) once over 1 to 2 minutes; reassess pH, serum bicarbonate level, and clinical status every 2 hours. ● If pH remains below target, administer an additional 44.6 to 89.2 mEq (50 to 100 ml) sodium bicarbonate or initiate a continuous infusion. |
|
Infusion therapy ● Calculate the bicarbonate deficit formula. ● Sodium bicarbonate estimated dose (mEq) = 0.5 × weight (kg) × [goal serum bicarbonate – observed serum bicarbonate (mEq/L)] ● Administer the calculated amount of bicarbonate (mEq) over 2 to 4 hours and reassess pH, serum bicarbonate level, and clinical status every 2 hours, and adjust dose as needed until goals are reached. Example; 0.5×50(kg) × [24-18] = 150 mEq (which is 75 ml/hour) |
|
Hyperkalemia with cardiac arrest: Intermittent bolus: IV: 50 mEq over 5 minutes. |
|
Hyperkalemia with metabolic acidosis:150 mEq in 1 L of D5W over 2 to 4 hours. |
