Abstract:
Objective To explore the effects of two methods of video laryngoscope insertion on the success rate of tracheal intubation and postoperative pharyngeal complications.Methods We selected 80 elective surgerypatients with American Society of Anesthesiologists(ASA)classification Ⅰ to Ⅱ who had no difficult airway in preoperative assessment under general anesthesia with orotracheal intubation.They were aged 18 to 65 years old and there were no restrictions on height and weight.The patients were randomly divided into a group with laryngoscope inserted through the middle of the mouth(group M)and a group with laryngoscope inserted through the right corner of the mouth(group C),with 40 cases in each group.Observe the laryngoscope exposure grading,oropharyngeal mucosal bleeding,first-time intubation success rate,and occurrence of pharyngeal pain and hoarseness within 48 hours after surgery in both groups;record the patients'systolic blood pressure(SBP),diastolic blood pressure(DBP),and heart rate(HR)among admission to the room(T0),after giving anesthesia drugs(T1),immediately after intubation(T2),1 min after intubation(T3),and 3 min after intubation(T4).Results The SBP of group M was lower than that of group C at T3(P＜0.05);There was no statistically significant difference in laryngoscope exposure grading between the two groups(P＞0.05).The intubation time,oropharynx mucosal bleeding and the cases of sore throat within 48 hours of group M were less than those in group C(P＜0.05).The success rate of primary intubation in group M was higher than that in group C(P＜0.05).Conclusion Inserting a video laryngoscope through the middle of the mouth can reduce oropharyngeal mucosal bleeding,improve the success rate of intubation,and reduce the incidence of postoperative pharyngeal complications.
