The comparison of the GlideScope and direct laryngoscopy in snoring surgery under general anesthesia endotracheal intubation

Abstract

Objective To compare effect of the GlideScope and direct laryngoscopy in snoring surgery.Methods Fourty patients scheduled for orotracheal intubation of general anesthesia in snoring surgery wererandomly divided into GlideScope group ( A group) and direct laryngoscope group ( B group). Two groups were recorded values of heart rate (HR),systolic blood pressure (SBP), diastolic blood pressure (DBP)before induction (T1), after induction (T2), intubation (T3) and 1 (T4), 3 (T5), 5 (T6) min after intubation and plasma norepinephrine (NE) concentrations in T1, T5, T6. Results ( 1 ) Values of HR, SBP and DBP of two groups were compared in T1 and T2, the difference was not significant ( P ＞ 0.05 ); Values of SBP and DBP of two groups compared T1 to T2, and the difference was significant ( P ＜ 0. 05); (2) Values of HR, SBP and DBP of two groups compared in T3, T4 and T5, and the difference was statistically significant (P ＜0.05);(3 ) Values of the concentration of plasma NE of two groups compared in T1 ,T5 and T6, and the difference was statistically significant ( P ＜ 0. 05 ). Conclusion Cardiovascular response and stress response of orotracheal intubation using a videolaryngoscope is lower than using ordinary laryngoscope in snoring surgery.
