Abstract
We have assessed trachea/ intubating conditions in 60 AS A I or II patients after induction of anaesthesia with propofol 2.5 mg kg-1 and alfentanil 10 or 20 fig kgr' with or without i. v. lignocaine 1 mg kg1. No neuromuscular blocking agents were administered. Patients were allocated randomly to four groups: group 1 = propofol-alfentanil 10 fig kg-1; group 2 = propofol-alfentanil 10 fig kg-1-lignocaine Imgkgr1; group 3 = propofol-alfentanil 20 jig kg-1; group 4 = propofol-alfentanil 20 fig kg-1-lignocaine 1 mgkgr. Intubating conditions were assessed as acceptable or unacceptable on the basis of a scoring system dependent on ease of faryngoscopy, vocal cord position and coughing on insertion of the trachea/ 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. (Br. J.
