Abstract :

Background: A prospective observational study to study the incidence and risk factors of post–operative sore throat (POST) in patients undergoing elective surgeries under general anaesthesia with endotracheal tube.

Methods: This was a prospective observational study done on 1000 patients to study the incidence and risk factors of POST. The data was analysed using SPSS–10 for Windows statistical software. Pearson’s Chi Square test was the statistical test of significance.

Results: ETT size 7.0 decreased and ETT tube size 8.0 and above increased the risk for POST and hoarseness in both sexes in the early postoperative period. It was noted that the incidence of POST was more in elective cases (26.2%) compared to emergency cases (17.7%). Intubation by a trained anaesthesiologist caused lesser cases of POST (32.5% vs. 23.5%). The symptoms of POST surfaced mostly at 8 hour after surgery (35.5%). Men developed more POST than women (59.3% vs. 40.7%). A low cuff pressure decreased the incidence of POST. Incidence of POST increases with the duration of surgery.

Conclusion: Endotracheal tube size 7.0 decreased postoperative sore throat. Incidence of POST was more in elective cases compared to emergency cases and surfaced mostly at 8 hour after surgery. Men more prone to POST than women. Incidence of POST increases with the duration of surgery many attempts and increasing cuff pressure.
