Pediatric patients receiving naloxone within 48 h of anesthesia: a case-control study.

PURPOSE

Excessive narcotization in pediatric surgical patients has not been well characterized. This report describes the use of postoperative naloxone in pediatric patients.

METHODS

Pediatric surgical patients from January 1, 2010, through June 30, 2016, who underwent general anesthesia and received naloxone within 48 h postoperatively were identified and matched 1:1 with controls by age, sex, and procedure. Cases and controls underwent retrospective chart review.

RESULTS

Forty-seven patients received naloxone, with a rate of 2.0 (95% CI 1.5-2.7) per 1000 anesthetics. Indications were respiratory depression (n = 19), facilitating extubation (n = 15), and reversing sedation (n = 13), and 44 cases received naloxone in a monitored environment. The median (interquartile range) naloxone dose was 4.0 (2.0-23.5) mcg/kg, and five patients (11%) later required subsequent naloxone treatments. Their characteristics were similar to controls, including opioid medications, except cases that had signs of respiratory depression before naloxone administration. The outcomes were similar, although more cases were admitted to the intensive care unit before naloxone administration. One patient died 13 days postoperatively of unrelated causes.

CONCLUSION

Postoperative naloxone administration in pediatric patients is rare. The observation that most administrations occurred in a monitored setting implies that at-risk patients had been appropriately identified and kept under closer surveillance.
