Dexmedetomidine and Iatrogenic Withdrawal Syndrome in Critically Ill Children

Crit Care Nurse. 2021 Feb 1;41(1):e17-e23. doi: 10.4037/ccn2021462.

Abstract

Background: Iatrogenic withdrawal syndrome is a well-known adverse effect of sedatives and analgesics commonly used in patients receiving mechanical ventilation in the pediatric intensive care unit, with an incidence of up to 64.6%. When standard sedative and analgesic treatment is inadequate, dexmedetomidine may be added. The effect of supplemental dexmedetomidine on iatrogenic withdrawal syndrome is unclear.

Objective: To explore the potentially preventive effect of dexmedetomidine, used as a supplement to standard morphine and midazolam regimens, on the development of iatrogenic withdrawal syndrome in patients receiving mechanical ventilation in the pediatric intensive care unit.

Methods: This retrospective observational study used data from patients on a 10-bed general pediatric intensive care unit. Iatrogenic withdrawal syndrome was measured using the Sophia Observation withdrawal Symptoms-scale.

Results: In a sample of 102 patients, the cumulative dose of dexmedetomidine had no preventive effect on the development of iatrogenic withdrawal syndrome (P = .19). After correction for the imbalance in the baseline characteristics between patients who did and did not receive dexmedetomidine, the cumulative dose of midazolam was found to be a significant risk factor for iatrogenic withdrawal syndrome (P < .03).

Conclusion: In this study, supplemental dexmedetomidine had no preventive effect on iatrogenic withdrawal syndrome in patients receiving sedative treatment in the pediatric intensive care unit. The cumulative dose of midazolam was a significant risk factor for iatrogenic withdrawal syndrome.
