Abstract
BackgroundPostoperative sore throat (POST) is a common problem following endotracheal (ET) intubation during general anesthesia. The objective was to compare the incidence and severity of POST during routine intubation with Glidescope (GL) and Macintosh laryngoscope (MCL).MethodsOne hundred forty adult patients ASA I and II with normal airway, scheduled to undergo elective surgery under GA requiring ET intubation were enrolled in this prospective randomized study and were randomly divided in two groups, GL and MCL. Incidence and severity of POST was evaluated at 0, 6, 12 and 24 h after surgery.ResultsAt 0 h, the incidence of POST was more in MCL than GL (n = 41 v.s n = 22, P = 0.001), and also at 6 h after surgery (n = 37 v.s n = 23, P = 0.017). Severity of POST was more at 0, 6 and 12 h after surgery in MCL (P < 0.001, P = 0.001, P = 0.004 respectively).ConclusionsRoutine use of GL for ET tube placement results in reduction in the incidence and severity of POST compared to MCL.Trial regisrationClinicalTrials.gov NCT02848365.

At 0 h, the incidence of POST was higher in Macintosh laryngoscope (MCL) than GL (n = 41 v.s n = 22, P = 0.001) and at 6 h after surgery (n = 37 v.s n = 23, P = 0.017); there was no significant difference in the incidence of POST at 12 h (n = 31 v.s n = 20, P = 0.053) and at 24 h (n = 15 v.s n = 7, P = 0.063)
Our results show that to intubation (TTI) was higher with MCL compared to GL which contributed to higher incidence of POST in this group
Summary
Postoperative sore throat (POST) is a common problem following endotracheal (ET) intubation during general anesthesia. The objective was to compare the incidence and severity of POST during routine intubation with Glidescope (GL) and Macintosh laryngoscope (MCL). Postoperative sore throat (POST) is a common problem following the use of endotracheal (ET) intubation during general anesthesia (GA) [1]. It leads to dissatisfaction and discomfort after surgery and can delay a patient’s return to normal routine activities [2]. The incidence of POST after ET intubation varies from 14.4–90% [1, 4, 5]. ET intubation is commonly performed under direct laryngoscopy using Macintosh laryngoscope (MCL). On search of literature we found contrasting results regarding the incidence of POST while using GL and
