【 摘 要 】
Aim: The aim of this prospective randomized blinded study was to evaluate clinical effectiveness of three different sedation protocols (intravenous propofol vs. ketamine vs ketofol) in children scheduled for dental treatment.Methodology: Seventy five ASA I patients were enrolled; were randomly selected from 6-12 years aged children with documented high anxiety level and were randomly divided into 3 groups: ketamine treated group (Group K) – received a priming dose of 1 mg/kg, followed by continuous infusion dose of 50-60 µg/kg/min, propofol treated group (Group P) – received priming dose of 2 mg/kg, followed by continuous infusion dose of 70-90 µg/kg/min, and ketamine plus propofol treated group (ketofol) (Group KP) – which received priming dose of 0.6 mg/kg, followed by continuous infusion dose of 40-60 µg/kg/min. During the study period, vital signs of children, the level of sedation using BIS monitor and time interval needed for full recovery were recorded every 5 min. The levels of changing anxiety were measured using Children’s Fear Survey Schedule – Dental Subscale (CFSS-DS) and face version of the Modified Child Dental Anxiety Scale (MCDASf).
