Table 1: No difference is detected in Group D and Group S patients 'age, gender distribution, BMI values, tracheostomized life time and ASA rates (p > 0.05). Time to loss of response to command was shorter in Group D than Group S while concentration percentage of expired inhalation agent was higher in Group D than Group S (p < 0.05).
