ABSTRACT
Objective:To explore the application and safety of visual endotracheal tube in tracheal intubation in patients with gen eral anesthesia operation.Methods:220 patients with general anesthesia operation in Department of Anesthesiology,Guangdong No.2 provincial people's hospital firom October 2014 to December 2016 were selected,110 patients were treated with visual endotracheal intubation as observation group,110 patients were treated with general endotracheal intubation as control group.The number of intubation,intubation times and complication rate in the two groups were contrasted,compared the heart rate (HR),systolic blood pressure (SBP),diastolic blood pressure (DBP) and oxygen saturation (SpO2) in the two groups at before induction of anesthesia (T0),after induction of anesthesia (T1),airway intubation (T2),5 min after intubation (T3).Results:The number of intubation and intubation times in the observation group were significantly less than those in the control group,the differences were statistically significant (P＜0.05);At each time point,the HR,SBP,DBP and SpO2 in the two groups were no significant difference (P＞0.05);The HR,SBP,DBP and SpO2 in the two groups at T1 were significantly less than T0,T2,T3,the differences were statistically significant (P＜0.05);The incidence of throat pain in the observation group (0.91％) was significantly less than that in the control group (7.27％),the difference was statistically significant (P＜0.05).Conclusion:Use visual endotracheal tube in tracheal intubation in patients with general anesthesia operation is satisfactory,can effectively reduce the time of intubation and intubation times,and has good security,it is worthy of clinical application.
