Purpose: In this study we wanted to compare bolus propofol and ketamine as an adjuvant to
remifentanil-based total intravenous anesthesia for pediatric rigid bronchoscopy.
Materials and Methods: Forty children under 12 years of age scheduled for rigid bronchoscopy
were included. After midazolam premedication, remifentanil infusion 1 µg/kg/min was started
and patients were randomly allocated to receive either propofol (Group P) or ketamine (Group
K) and mivacurium for muscle relaxation. Anesthesia was maintained with remifentanil infusion
1 µg/kg/min and bolus doses of propofol or ketamine. After rigid bronchoscopy remifentanil
0.05 µg/kg/min was maintained until extubation. Hemodynamic parameters, emergence
characteristics and adverse events were evaluated.
