Insights
Fifty percent of pediatric patients experienced withdrawal syndrome after prolonged fentanyl and midazolam infusions. Longer infusion duration and higher cumulative drug doses were identified as key risk factors for this withdrawal syndrome.
Area of Science:
- Pediatric Intensive Care
- Pharmacology
- Clinical Medicine
Background:
- Prolonged use of fentanyl and midazolam is common in pediatric intensive care for sedation and analgesia.
- Understanding withdrawal syndrome incidence and risk factors is crucial for patient safety.
Purpose of the Study:
- To determine the incidence of withdrawal syndrome in children after continuous fentanyl and midazolam infusion.
- To identify risk factors associated with the development of withdrawal syndrome.
Main Methods:
- Retrospective cohort study in a pediatric intensive care unit.
- Included 48 pediatric patients receiving continuous fentanyl and midazolam for at least 48 hours.
- Collected data on demographics, drug doses, infusion duration, and withdrawal syndrome outcomes.
Main Results:
- Withdrawal syndrome occurred in 50% of patients.
- Significant risk factors included longer infusion duration and higher cumulative doses of fentanyl and midazolam.
- Typical onset was 12-36 hours post-infusion, with mild to moderate severity. Methadone was the primary treatment.
Conclusions:
- Continuous infusion of fentanyl and midazolam in children is associated with a high incidence of withdrawal syndrome.
- Prolonged infusion duration and increased cumulative drug doses are significant risk factors.
Objective:
To determine the incidence of withdrawal syndrome after prolonged infusion of fentanyl and midazolam in children, and the associated risk factors.
Design:
Historic or retrospective cohort study.
Setting:
Pediatric Intensive Care Unit in an academic center.
Patients:
Forty-eight pediatric patients who received sedation and analgesia only with fentanyl and midazolam through continuous infusion for at least 48 hours.
Interventions:
None.
Main Variables Of Interest:
Collected data included demographic and clinical parameters, dose and duration of sedation received, and incidence, severity and treatment of withdrawal syndrome.
Results:
Fifty percent of the patients developed withdrawal syndrome. There were significant differences between the patients who developed withdrawal syndrome and those who did not, in terms of the duration of infusion and the cumulative doses of both drugs. A cumulative fentanyl dose of 0.48 mg/kg, a cumulative midazolam dose of 40 mg/kg, and a duration of infusion of both drugs of 5.75 days were risk factors for the development of withdrawal syndrome. Most children developed mild or moderate disease, beginning about 12-36 hours after weaning from infusion. Methadone was used in most cases for treating withdrawal.
Conclusions:
There is a high incidence of withdrawal syndrome in children following the continuous infusion of midazolam and fentanyl. The duration of infusion of both drugs and higher cumulative doses are associated with the development of withdrawal syndrome.
