Study of No-machine Oral Intubation in Patients during General Anesthesia

Objective:To evaluate the no-machine oral intubation in patients during general anesthesia.Methods:Sixty ASA I~II patients(aged 25~75 yrs) under general anesthesia were randomly divided into 2 groups(n=30 each) group I(no-machine oral intubation group)and group II(classic intubation group).The time of intubation,first success rate and cardiovascular response to tracheal intubation were recorded.Results:All cases were successful in intubation.The time of intubation in group I was reduced compared with group II.SBP,DBP and MAP were significantly higher immediately after intubation than that immediately after induction in the 2 groups.SBP was significantly lower in group I and higher in group II immediately after intubation than that immediately after induction.There was no significant difference in complications between the 2 groups.Conclusion:The no-machine oral intubation is a better way for airway management.
