Notes:
The current study was designed to determine the anaesthetic induction time required for tracheal intubation (TimeEI) with equipotent inspired concentrations of 5% sevoflurane and 2.5% halothane in oxygen. TimeEI that prevents 50% and 95% of patients from coughing and gross purposeful muscular movements after intubation was defined as TimeEI50 and TimeEI95, respectively. Thirty-six patients aged 1–7 years were enrolled in the study. Anaesthesia was induced via mask and when TimeEI attained a predetermined value, intubation was performed using an uncuffed tube. Each TimeEI at which tracheal intubation was attempted was predetermined according to the up-and-down method. When intubation was accomplished without gross purposeful muscular movements, it was considered a smooth intubation. Determination with this method revealed that TimeEI50 and TimeEI95 for the sevoflurane/halothane groups were 147/214 s and 194/255 s, respectively. In conclusion, it is possible to determine TimeEI using an inspired sevoflurane concentration of 5% and halothane 2.5% in oxygen. The technique with 5% sevoflurane seems more practical for paediatric anaesthesia induction in busy clinical situations.
