Study summary

The study will evaluate the post-operative morphine-sparing effect, pain reduction, and side effects of a continuous ketamine infusion after tonsillectomy in pediatric patients.

Read the detailed description

Eligible pediatric patients that are undergoing tonsillectomy for sleep-disordered breathing or obstructive sleep apnea AND are to be admitted into a monitored setting will be recruited for this study. They will be randomized into two groups:1) Control group receiving continuous infusion of saline (placebo) and 2) Study group receiving continuous infusion of low-dose ketamine at 0.1 mg/kg/hr. Both patients will receive scheduled oral acetaminophen and rescue intravenous morphine as required. The infusions will be stopped at 0600 the next morning. Morphine requirements, pain scores at selected times, central nervous system side effects, and adverse cardiorespiratory events will be recorded.
