Calcium in cardiac resuscitation
Trials show no benefit of calcium administration in cardiac resuscitation. Theoretically, it should improve excitation-contraction coupling and increase automaticity, but calcium causes cell death and ischaemia.
Calcium is indicated during resuscitation from pulseless electrical activity if this is thought to be caused by:
- hyperkalaemia
- hypocalcaemia
- overdose of calcium-channel-blocking drugs
- overdose of magnesium (e.g. during treatment of pre-eclampsia)
In adults, the initial dose of 10 ml 10% calcium chloride (6.8 mmol Ca2+) may be repeated if necessary
Notes:
- calcium can slow the heart rate and precipitate arrhythmias
- in cardiac arrest, calcium may be given by rapid intravenous injection. In the presence of a spontaneous circulation it should be given slowly
- do not give calcium solutions and sodium bicarbonate simultaneously by the same venous access.
