Terlipressin, a long-acting analog of vasopressin, has been used successfully in patients with extremely low cardiac output, but its application in children following open heart surgery is limited. ⋯ Terlipressin caused significant improvement in hemodynamic, respiratory, and renal indices in children with extremely low cardiac output after open heart surgery. Further controlled studies are needed to confirm the drug's safety and efficacy in this population.

To provide further evidence of cardiovascular adverse effects of ondansetron, including new-onset atrial fibrillation, ST segment elevation, and chest pain subsequent to ondansetron administration, and to review cardiovascular adverse events related to several 5-hydroxytryptamine type 3 (5-HT(3)) receptor antagonists. ⋯ This case report supports the concern regarding cardiovascular adverse effects of ondansetron. Clinicians should be aware of cardiovascular adverse reactions that may be associated with intravenous ondansetron and monitor for electrocardiographic changes as indicated. Further investigation is needed to delineate the actual incidence of cardiovascular effects associated with ondansetron and whether the intravenous rate of administration is a contributing factor.
