Not Applicable
Completed
Conditions
Hoarseness of Voice
Sore-throat
Interventions
Procedure: Intubation
Registration Number
NCT05531617
Lead Sponsor
Seth Gordhandas Sunderdas Medical College
Brief Summary

The aim of this study is to compare the incidence of postoperative sore throat after intubation with two different types of laryngoscopes.

Detailed Description

Postoperative sore throat is a well known complication after endotracheal intubation. One of the major contributing factors is trauma associated with laryngoscopy. With decreased force applied to visualise cords, video laryngoscopes should decrease the incidence of postoperative sore throat. In this study we compared the incidence and severity of postoperative sore throat when laryngoscopy was done using c-mac video laryngoscope D-blade( group V) versus Macintosh laryngoscope (Group M). Method: Fifty four American society of Anaesthesiologists (ASA) 1\&2 patients between age 18-60 years , undergoing laproscopic surgeries of short duration were included in this study and laryngoscopy was done with Macintosh laryngoscope in M group and with C MAC video laryngoscope D blade in V group. Patients were followed up 2hours, 6hours, 12hours and 24hours in postoperative period to see postoperative sore throat and hoarseness of voice .

Primary Outcome Measures
NameTimeMethod
The incidence and severity of postoperative sore throat measuredUpto 24 hours after surgery

The incidence and severity of Postoperative sore throat is measured after surgery at 2hours, 6hours, 12hours and 24 hours based on a scaling system as described below

* No sore throat at any time since the operation Grade 0

* Minimal - patient answered in the affirmative when asked about sore throat - Grade1

* Moderate - patient complained of sore throat on his/her own - Grade 2

* Severe - patient is in obvious distress-Grade 3

Secondary Outcome Measures
NameTimeMethod
The incidence and severity of Hoarseness of voiceUpto 24 hours after surgery

The incidence and severity of Postoperative hoarseness of voice measured at 2hours, 6hours, 12hours and 24hours post surgery by scaling system as described below

* No complaint of hoarseness at any time since the operation - Grade 0

* Minimal - minimal change in quality of speech. Patient answers in the affirmative only when enquired about - Grade 1

* Moderate - moderate change in quality of speech of which the patient complains on his/her own - Grade 2

* Severe - gross change in the quality of voice perceived by the observer - Grade 3
