The current practice of tracheal intubation is normally performed by using muscle relaxants. The recent studies report that, propofol, due to its relxation effect on the upper airways, provides appropriate intubation conditions even without the use of muscle relaxants. Intubation may turn to a problem in cases where muscle relaxants are to he avoided. The present study is performed to evaluate the suitability of the operating conditions for laryngoscopy and intubation, carried out after the induction of thiopentone and propofol, without muscle relaxants. 82 patients of ASA I or II status scheduled for elective surgery are included in the study. The patients are divided into four groups. Thiopentone (7 mg/kg) or propofol (2.5 mg/kg) is supplemented either with lidocaine IV (1.5 mg/kg) or 2 % lidocaine LTA (7 ml); each group are additionally given alfentanil, 30 mcg/kg. The patients are not premedicated. The assessment of jaw was relaxed in 55-95 % of the patients, the ease of intubation was assessed as 'very easy' in 55-85 % of the patients (the differences between groups were in favor of propofol group, p<0.05). The other parameters; ease of visualisation of larynx, position of vocal cords, tolerance to tracheal tube, and hemodynamic changes (HR, SAP, DAP, SpO2); did not show significant differences. In conclusion, it is found out that for the intubation without muscle relaxants, the combination of propofol with low dosage narcotics and IV lidocaine reveals better intubating conditions than the combination of thiopentone with similar agents.
