We have assessed tracheal intubating conditions in 60 ASA I or II patients after induction of anaesthesia with propofol 2.5 mg kg-1 and alfentanil 10 or 20 micrograms kg-1 with or without i.v. lignocaine 1 mg kg-1. No neuromuscular blocking agents were administered. Patients were allocated randomly to four groups: group 1 = propofol-alfentanil 10 micrograms kg-1; group 2 = propofol-alfentanil 10 micrograms kg-1-lignocaine 1 mg kg-1; group 3 = propofol-alfentanil 20 micrograms kg-1; group 4 = propofol-alfentanil 20 micrograms kg-1-lignocaine 1 mg kg-1. Intubating conditions were assessed as acceptable or unacceptable on the basis of a scoring system dependent on ease of laryngoscopy, vocal cord position and coughing on insertion of the tracheal tube. Intubating conditions were acceptable in 20%, 73%, 73% and 93% of patients in groups 1-4, respectively. Intubating conditions were better and there was less coughing in the lignocaine group.
我们评估了60例ASA I或II级患者在使用2.5 mg/kg丙泊酚和10或20 μg/kg阿芬太尼诱导麻醉后，无论是否静脉注射1 mg/kg利多卡因时的气管插管情况。未使用神经肌肉阻滞剂。患者被随机分为四组：第1组 = 丙泊酚-阿芬太尼10 μg/kg；第2组 = 丙泊酚-阿芬太尼10 μg/kg-利多卡因1 mg/kg；第3组 = 丙泊酚-阿芬太尼20 μg/kg；第4组 = 丙泊酚-阿芬太尼20 μg/kg-利多卡因1 mg/kg。根据依赖于喉镜检查的难易程度、声带位置和气管导管插入时咳嗽情况的评分系统，将插管情况评估为可接受或不可接受。第1 - 4组患者中插管情况可接受的分别为20%、73%、73%和93%。利多卡因组的插管情况更好，咳嗽也更少。
