Dysrhythmias During General Anesthesia in Children

Brief Summary

Official Title: “Dysrhythmias During General Anesthesia in Children”

To describe the types and incidence of cardiac dysrhythmias that occur under anesthesia in the present anesthesia environment.

  • Study Type: Observational
  • Study Design: Observational Model: Cohort, Time Perspective: Retrospective
  • Study Primary Completion Date: August 2005

Detailed Clinical Trial Description

It is unclear what the current state of anesthesia associated dysrhythmias is in the pediatric population. This was last investigated retrospectively in 1992 when the predominant volatile agent used for inhalation induction was halothane. Sevoflurane was approved by the Food and Drug Administration in 1995. Since that time, Sevoflurane has displaced halothane as the agent of choice for inhalation induction and has relegated halothane to be used in a narrow niche which primarily involves patients with very specific congenital heart diseases. It has been described that halothane has a larger proarrhythmic effect than sevoflurane for ventricular dysrhythmias. With the transition from the halothane to the sevoflurane era, a reassessment of the incidence and types of dysrhythmias occurring in non-cardiac pediatric patients is important.
