Brief Summary:
  • Ketamine provides effective and relatively safe sedation analgesia for primary closure of lacerated pediatric patients
  • However, deep sedation and adverse effects suggest the opportunity to develop alternative strategies
  • We compared the efficacy and adverse effects of ketamine to those of N2O gas for analgesia and anxiolysis during primary repair of lacerated pediatric patients

Condition or disease Intervention/treatment Phase
Moderate Sedation Laceration Drug: N2O gas vs ketamine Phase 4

Detailed Description:
  • There were 32 children who were randomly assigned
  • Recovery times were markedly shorter in the N2O group compared with those in the ketamine group (median, 0.0 min (interquartile range [IQR], 0.0-4.0 min) vs. median, 21.5 min (IQR, 12.5-37.5 min), N2O vs. ketamine, respectively, p < 0.05)
  • Sedation levels were deeper in the ketamine group than in the N2O group, but pain scales were comparable between groups
  • No difference was observed in the satisfaction scores by physicians, parents, or nurses.
  • N2O inhalation was preferable to injectable ketamine for pediatric patients because it is safe, allows for a faster recovery, maintains sufficient sedation time, and does not induce unnecessarily deep sedation
