To report a cardiopulmonary resuscitation attempt in a 20-month-old child employing a combination of vasopressin and epinephrine.. Case report.. Out-of-hospital cardiopulmonary resuscitation.. A 20-month-old child found in cardiac arrest after submersion.. Dispatcher-assisted basic life support was initiated immediately after pulling the child out of the water. The emergency medical service crew arrived approximately 6 mins later and found a hypothermic, cyanotic child in cardiocirculatory arrest. The first electrocardiogram showed sinus bradycardia. After intubation and administration of epinephrine and atropine with no effect, an intravenous bolus of 0.2 mg of epinephrine and 10 IU of vasopressin resulted in restoration of spontaneous circulation. The boy was flown to a hospital and was discharged 23 days later to a rehabilitation facility. He returned home 6 months after the accident, where further rehabilitation efforts are pending.. Bystander cardiopulmonary resuscitation, early and aggressive advanced life support, rewarming, and the combination of intravenous epinephrine and vasopressin were associated with sustained return of spontaneous circulation following hypothermic submersion-associated cardiac arrest.

Recent animal data have challenged the common clinical practice to avoid vasopressor drugs during hypothermic cardiopulmonary resuscitation (CPR) when core temperature is below 30 degrees C. In this report, we describe the case of a 19-year-old-female patient with prolonged, hypothermic, out-of-hospital cardiopulmonary arrest after near drowning (core temperature, 27 degrees C) in whom cardiocirculatory arrest persisted despite 2 mg of intravenous epinephrine; but, immediate return of spontaneous circulation occurred after a single dose (40 IU) of intravenous vasopressin. The patient was subsequently admitted to a hospital with stable haemodynamics, and was successfully rewarmed with convective rewarming, but died of multiorgan failure 15 h later. To the best of our knowledge, this is the first report about the use of vasopressin during hypothermic CPR in humans. This case report adds to the growing evidence that vasopressors may be useful to restore spontaneous circulation in hypothermic cardiac arrest patients prior to rewarming, thus avoiding prolonged mechanical CPR efforts, or usage of extracorporeal circulation. It may also support previous experience that the combination of both epinephrine and vasopressin may be necessary to achieve the vasopressor response needed for restoration of spontaneous circulation, especially after asphyxial cardiac arrest or during prolonged CPR efforts.
