title: Efficacy of an enteral 10-day methadone wean to prevent opioid withdrawal in fentanyl-tolerant pediatric intensive care unit patients.
abstract: OBJECTIVE
  To demonstrate the efficacy of a 10-day, single daily dose, enteral methadone weaning protocol for the prevention of opioid withdrawal symptoms in pediatric patients after prolonged fentanyl exposure.
  
  
  METHODS
  Prospective, observational study.
  
  
  METHODS
  Twenty-four-bed medical-surgical intensive care unit within a 222-bed pediatric teaching hospital.
  
  
  METHODS
  Twenty-nine children, aged 1 day to 19.8 yrs, who received methadone to prevent opioid withdrawal after prolonged continuous fentanyl infusion exposure.
  
  
  METHODS
  Institution of a standardized methadone weaning protocol.
  
  
  RESULTS
  All 29 patients had received a continuous fentanyl infusion; duration of exposure was 14.5 +/- 9.2 days, cumulative fentanyl dose was 1.93 +/- 1.53 mg/kg, and peak fentanyl infusion was 9.6 +/- 4.3 microg/kg per hr. Twenty-five (86%) of 29 patients successfully completed the methadone wean in 10 days. Withdrawal complications that required a weaning delay were seen in three patients, and one patient expired before completion. Sixteen patients were discharged to complete their weaning schedule at home without incident.
  
  
  CONCLUSIONS
  Opioid withdrawal symptoms in pediatric intensive care unit patients after prolonged fentanyl exposure can be avoided by using an enteral, 10-day, single daily dose methadone weaning protocol.
