Summary
This study identifies some of the preoperative characteristics that may influence a child's cooperation during induction of anaesthesia, and the ability of both resident and staff anaesthetists to predict cooperation. Five hundred unmedicated children aged 2–12 participated in the study. The characteristics that influenced cooperation were identified. Children four years of age or younger cooperated less regardless of race, gender or the technique used. Children who had had prior anaesthetics cooperated significantly less than those who had no previous anaesthesia. The child's response to a previous anaesthetic correlated with cooperation for the current anaesthetic. The child's cooperation during blood drawing correlated with cooperation during induction. Preoperative preparation resulted in improved cooperation ratings. No differences in cooperation were observed for different induction techniques. Success in prediction was correlated with the anaesthetist's training and experience. Anaesthetists had more trouble predicting difficult than smooth inductions.
