Abstract

Context: Postoperative sore throat (POST) is a very common complaint following tracheal intubation. Although it resolves spontaneously, efforts must be taken to reduce it.

Aims: This study aims to compare the effect of cuff inflation using manometer versus conventional technique on the incidence of POST. Secondary objectives were to assess the incidence postoperative hoarseness and cough.

Settings and design: A total of 120 patients were included in this prospective observational comparative study.

Subjects and methods: After approval from the hospital ethics committee, consenting American Society of Anesthesiologists physical status Class I and II patients, scheduled for gynecologic laparoscopic surgery under general anesthesia, were included. They were randomly allocated by closed envelope technique to either Group A where the cuff pressure was adjusted to 25 cmH2O using a manometer or Group B where cuff inflation was guided clinically. Patients were monitored for sore throat, hoarseness of voice, and cough postoperatively.

Statistical analysis used: To calculate the incidence of sore throat, hoarseness, and cough, descriptive statistics were applied. For checking association of sore throat and cuff pressure, Chi-square test and for comparing numerical values independent sample t-test were applied.

Results: The incidence of POST was significantly less in Group A than in B (P < 0.001) up to 24 h. Incidence of hoarseness was less in Group A and incidence of cough was higher in Group B, but these differences were not statistically significant.

Conclusion: Cuff inflation guided by manometer significantly reduces the incidence of POST.

Keywords: Cough; cuff; hoarseness; intubation; laparoscopic; manometer; sore throat.
