Beneficial effects of terlipressin in prolonged pediatric cardiopulmonary resuscitation: a case series.

OBJECTIVE: Arginine vasopressin was found in experimental and clinical studies to have a beneficial effect in cardiopulmonary resuscitation. The American Heart Association 2000 guidelines recommended its use for adult ventricular fibrillation arrest, and the American Heart Association 2005 guidelines noted that it may replace the first or second epinephrine dose. There is little reported experience with arginine vasopressin in cardiopulmonary resuscitation of children. Terlipressin, a long-acting analog of arginine vasopressin, has recently emerged as a treatment for vasodilatory shock in both adults and in children, but evidence of its effectiveness in the pediatric setting is sparse. The objective of this retrospective study is to describe our experience in adding terlipressin to the conventional protocol in children with cardiac arrest.

DESIGN: Retrospective case series study.

SETTING: An 18-bed pediatric critical care department at a university-affiliated tertiary care children's hospital.

PATIENTS: Seven pediatric patients with asystole, aged 2 months to 5 yrs, who experienced eight episodes of refractory cardiac arrest and did not respond to conventional therapy.

INTERVENTIONS: Addition of terlipressin to epinephrine during cardiopulmonary resuscitation of children.

MEASUREMENTS AND MAIN RESULTS: Return of spontaneous circulation was monitored and achieved in six out of eight episodes of cardiac arrest. One patient died 12 hrs after return of spontaneous circulation, and four patients survived to discharge with no neurologic sequelae.

CONCLUSIONS: The combination of terlipressin to epinephrine during cardiopulmonary resuscitation may have a beneficial effect in children with cardiac arrest. More studies on this drug's safety and efficacy in this setting are mandated.
