Abstract

Objectives:Postoperative sore throat (POST) is a common complication related to endotracheal intubation. The aim of this study was to compare the incidence of POST in patients intubated by trainee anaesthetist using Video Laryngoscope™ (VDL) or Conventional Macintosh Laryngoscope (CL).Methods:Total 110 patient scheduled for elective laparoscopic cholecystectomy were included from main operating room of Aga Khan University Hospital between June 2017-2018. The standardized perioperative protocol was used for general anaesthesia. Selected patients were randomly allocated into conventional laryngoscopy (CL) group or video laryngoscopy (VDL) group. The evaluation of sore throat was done at 1st, 12th and 24th hour postoperatively using a ten-point visual analogue scale.Results:The demographic characteristics, including intubation time, related complications or any other maneuver required were similar between the groups. The incidence of POST at 1st hour was 47% patients in CL group and 38% in VDL group (p=0.335). At 12th hour, 34.5% patients in CL and 38% in VDL reported POST (p=0.692). Similarly at 24th hour, 25% patients in CL and 16% in VDL group reported POST (p=0.669).Conclusions:There was no significant difference in incidence of POST for patients intubated by trainee anaesthetists using either CL or VDL. Objective evidence of training and laryngoscope technique can impact of POST.

Highlights

Airway management is a vital aspect of maintaining oxygenation and ventilation during General anaesthesia (GA)
The study was conducted in the main operating room Aga Khan University for a period of one year after approval of study on 19th June 2017. (June 2017-2018) All adult patients of age between 20-60-year, American Society of Anaesthesiologist (ASA) Grade I and II, scheduled for elective laparoscopic cholecystectomy were enrolled in the study
After taking informed consent selected patients were randomly allocated by a computer-generated number, either into conventional laryngoscopy (CL) group or video laryngoscopy (VDL) group using sealed envelope technique

Summary

Introduction

Airway management is a vital aspect of maintaining oxygenation and ventilation during General anaesthesia (GA). The technique requires laryngoscope-guided insertion of the tracheal tube, which needs to be passing down beyond the vocal cords. The procedure is not risk free and has associated complications.[1] The early physiological effects of intubation might be presented in form of hemodynamic fluctuations under GA.[2] While, complications like post-operative sore throat (POST) evident during recovery phase.[3] The reported incidence of POST is somewhere between 30-70%.4. The trauma related to intubation is one of the main The reported incidence of POST is somewhere between 30-70%.4 The trauma related to intubation is one of the main
