Abstract:
Objective To compare the effects of 4 different shaping angle tubes on the success rate of tracheal intubation and postoperative pharyngeal complications among anesthetic beginners.Methods 160 patients who underwent laparoscopic cholecystectomy under general anesthesia,with ASA classification Ⅰ to Ⅱ,no history of difficult airway,were randomly divided into 4 groups according to the catheter shape and tip shaping angle:35°banana-shaped elbow group(A Group),50°banana-shaped bent pipe group(Group B),35°straight pipe group(Group C),50°straight pipe group(Group D),with 40 cases in each group.After induction of general anesthesia,tracheal intubation is performed using a video laryngoscope.The Cormack-Lehane grade of laryngoscope exposure,external laryngeal compression,one-time success rate of intubation and intubation time were recorded.SPO2,HR and MAP were recorded before anesthesia induction(T0),at the end of anesthesia induction drug injection(T1),immediately after intubation(T2)and 1min after intubation(T3).The incidence of pharyngeal pain and hoarseness immediately after extubation and 24 hours after operation were followed up.Results There were no statistically significant differences in Cormack-Lehane classification,HR,and MAP among the four groups of patients at each time point(P>0.05).The number of cases requiring external laryngeal compression,intubation time,first-time intubation success rate,immediate postoperative sore throat,and immediate postoperative hoarseness rates in Groups B and D were all lower than those in Groups A and C,and the differences were statistically significant(P<0.05).Conclusion When using video laryngoscope for tracheal intubation,50°banana-shaped curved tube and 50°straight tube can shorten the intubation time,reduce postoperative complications,and have no obvious hemodynamic fluctuations.
