Abstract

We evaluated the incidence of hemodynamic adverse events in children who received prolonged continuous dexmedetomidine for ≥ 192 hours. Prolonged infusions of dexmedetomidine may additionally contribute to hemodynamic adverse events at time of discontinuation. The current practices regarding use of dexmedetomidine at time of dexmedetomidine discontinuation were also evaluated. This was a retrospective, chart review of 14 children who had received prolonged continuous dexmedetomidine infusions. Demographics, dexmedetomidine infusion characteristics, systolic and diastolic blood pressure, heart rate, use of rescue medication, and clonidine use characteristics were evaluated during dexmedetomdine infusion through 24-hr after last dose of dexmedetomidine. Average age was 5 years (range 7 months – 17 years). Average length of continuous dexmedetomidine was 10 days (range 8 – 19 days). Average dose of dexmedetomidine during initiation and maintenance was 1.25 mcg/kg/hr. The maximum rate of dexmedetomidine was 1.6 mcg/kg/hr. Statistically significant higher adverse event incidence rate seen during dexmedetomidine wean compared to initiation and maintenance (36.2% and 0.04%, p<0.05). No differences were seen in rate of adverse events comparing patients who were weaned with and without clonidine (39.9% and 37.8%, p=0.52). Prolonged continuous infusions of dexmedetomidine were well-tolerated with doses up to 1.6 mcg/kg/hr. A higher incidence of adverse events were seen during the period of wean compared to period of initiation and maintenance. Clonidine use at wean was not found to have an effect on decreasing the amount of hemodynamic adverse events at discontinuation.
