OBJECTIVE: Assess the postoperative use of dexmedetomidine (Precedex) in pediatric patients following airway reconstruction. STUDY DESIGN: Historical cohort study. SETTING: Tertiary medical center. SUBJECTS AND METHODS: A retrospective review of 24 children undergoing laryngotracheal reconstruction (LTR) or laryngeal cleft repair (LCR) was conducted. Twelve children were treated with standard sedation protocols where dexmedetomidine was administered in lieu of propofol (Diprivan); 12 age-, gender-, and procedure-matched controls were selected. Subjects were divided into groups based on duration of postoperative intubation for cross-comparison; group 1 was intubated <24 hours, group 2 was intubated 2 to 6 days, and group 3 was intubated 7 days or longer. Baseline heart rate and blood pressure measurements were compared to hourly measurements for the first 6 hours following initiation of dexmedetomidine or mechanical ventilation in the control group. Number of supportive respiratory interventions, adverse events, self-extubations, premature termination of dexmedetomidine, amount of muscle relaxants, agents to treat withdrawal, and length of stay were evaluated. RESULTS: Ten patients undergoing LTR and 2 patients undergoing LCR receiving dexmedetomidine were compared to 10 LTR and 2 LCR control patients. Overall, dexmedetomidine was well tolerated and without significant adverse effects, particularly in cases of short-term intubation or as a bridge to extubation. CONCLUSION: In cases requiring short-term intubation following airway reconstruction, dexmedetomidine may offer a safe alternative to propofol by providing readily reversible sedation during the periextubation period. Further studies are needed to determine the safety, efficacy, dosing, and potential complications of longer term dexmedetomidine administration in pediatric airway reconstruction.
