Study Overview
Brief Summary
Previous studies have already established that there is voice change after endotracheal intubation.Airway management is one of the significant responsibilities of a trained anaesthesiologist.Therefore ,a detailed observational study are required to evaluate the impact on laryngeal function after endotracheal intubation that is vocal acoustic changes on voice and vocal symptoms following endotracheal intubation by using PRAAT software by comparing the voice pre intubation and post extubation voice.
RESEARCH QUESTION : Does Post Endotracheal Intubation cause significant voice Change and vocal symptoms?
Inclusion criteria will be General Anaesthesia with Endotracheal intubation, patients aged 18 years and above belonging to ASA I-II, and to rule out any preexisting vocal cord lesions.
Exclusion criteria will be Endotracheal intubation during emergency surgery and in ICU, patient with history of preoperative URI or LRI within 14 days of recovery, reactive airway and any surgery that include manipulation of larynx or tracheostomy and past laryngeal surgery, pregnant woman.
The voice of the participants will be recorded and analysed preoperatively by using PRAAT software and will be compared with their voice postoperatively, 2 hours and 24 hours post extubation.
The acoustic analysis of voice will be performed by PRAAT software 6.2.14 version. The voice signal will be recorded with microphone inbuilt Macbook(laptop)M1 directly with sampling rate of 44100 Hz will be used. Prior to recording, patients will be asked to take a deep breath and to phonate vowels, /a/, /i/, or /u/. The Macbook microphone will be held at a distance of 10 cm from the mouth of the patient with ambient noise below 50 db.
PRAAT software 6.2.14 version will be used to record voice related parameters like Mean pitch (Fundamental frequency), Jitter%, Shimmer(dB), Harmonics to noise ratio (db) and Maximum Phonation time
The vocal symptoms will be evaluated in all patients in the study and it includes Sore throat, hoarseness, vocal fatigue, throat clearing and throat pain.
