Evaluation of preoperative Strepsils lozenges on incidence of postextubation cough and sore throat in smokers undergoing anesthesia with endotracheal intubation.

UNLABELLED

Post-operative sore throat (POST) is an undesirable side effect of endotracheal intubation. Pharmacological and non-pharmacological measures have been utilized for minimizing the morbidity caused by POST. We have tested use of Strepsils lozenges in providing efficacy for decreasing POST in smokers presenting for surgery under general anesthesia with endotracheal intubation.

MATERIALS AND METHODS

100 patients, 20-65 years, American Society of Anesthesiologists (ASA) physical status I and II, either sex, history of smoking, posted for elective surgical procedure of more than 1 hour, requiring general anesthesia with endotracheal intubation were included and randomly divided into groups (n = 50) to receive Strepsils (Group A) and sugar candy (Group B). The patients were assessed for cough, sore throat, and hoarseness of voice after extubation, 30 min, 12 hrs, and 24 hrs after extubation.

RESULTS

At extubation no cough was seen in 39 (78%) patients (group A) compared to 23 (46%) patients (Group B), and mild cough in 22% (Group A) and 52% (Group B). Incidence of sore throat at extubation was lower in group A compared to Group B (P = 0.04). At other times of observations (30 min,12 hrs and 24 hrs) there was a significant decrease in incidence of sore throat in Group A compared to Group B (P = 0.000). Hoarseness of voice was not observed in any patient in either group.

CONCLUSIONS

Use of preoperative Strepsils lozenges decreases incidence of POST and maybe utilized as a simple and cost-effective measure for decreasing the symptoms of POST and increasing the satisfaction of patients.
