Evaluation of tracheal intubating condition in adults after coinduction with propofol plus lidocaine and different doses of remifentanil

To evaluate tracheal intubation condition in adults after anesthetic coinduction with lidocaine and propofol and various doses of remifentanil. In three groups, induction was compared with lidocaine [1.5 mg/kg], propofol [2 mg/kg], and three varing doses of remifentanil [0.5-1-2 micro g/kg]. Tracheal intubation was graded according to the ease of laryngoscopy, the position of vocal cords, coughing, jaw relaxation and the movement of limbs. Hemodynamic variables were compared during preoxygination and 45 seconds after induction. There were 90 ASA I or ASA II patients with 30 in each group. Tracheal intubating condition was regarded as acceptable in 33%, 53% and 90% of patients in groups 1, 2 and 3 respectively. All three groups had a decrease in heart rate and mean arterial pressure after induction but this changes wasn't clinically significant. Tracheal intubating condition was best after induction with lidocaine 1.5mg/kg, propofol 2mg/kg and remifentanil 2microg/kg
