Vasopressin may be an alternative vasopressor drug during CPR. A subgroup analysis of a large prospective CPR investigation and of retrospective CPR studies suggests that vasopressin may be especially beneficial when combined with epinephrine. Beneficial effects of adding vasopressin were observed in other catecholamine-refractory shock states as well such as vasodilatory shock and haemorrhagic shock. In order to maximize effects of any vasopressor during CPR rapid aggressive chest compressions must be ensured to maximize blood flow and to enable advanced cardiac life support drugs to reach the arterial vasculature. We suggest alternating injections of 1 mg epinephrine . and 40 IU vasopressin . every 3-5 minutes during CPR until spontaneous circulation can be achieved or CPR efforts are terminated. Epinephrine has been employed for cardiac resuscitation for approximately 100 years 1 although it is known that this drug increases myocardial oxygen consumption during cardiopulmonary resuscitation CPR and increases the likelihood of cardiac failure after restoration of spontaneous circulation 2 . In contrast vasopressin proved to be beneficial over epinephrine as regards improving coronary perfusion pressure during CPR and as regards improving .
