ABSTRACT
Background: Postoperative sore throat (POST) is considered to be quite common complaint. Its symptoms tend to improve with time, but use of oral zinc lozenge has been shown to reduce the incidence and severity of POST. The aim of the present study was to find the efficacy of oral zinc sulfate, given 30 min preoperatively, in reducing POST, primarily caused by endotracheal intubation, till 24 hours after surgery.
Method: A prospective, randomized, double-blinded, placebo-control-trial study was conducted on 80 patients, further divided into two groups of 40 patients each, between the age group of 18-60 years, of either gender, in Super Specialty Hospital, GMC Jammu, over a period of 6-months. The two groups received either dispersible zinc tablet or a placebo. The severity of POST was graded on a 4-point scale ranging from 0 to 3 and evaluation was repeated at 30 min, 2, 4, and 24 hour, postoperatively.
Results: The difference in severity of sore throat was found to be statistically significant at all evaluation time intervals, except at 24 hours, which was quite lower in Zinc group. The overall incidence of POST in Zinc group was 26.3%, which was significantly higher at 50% in placebo group.
Conclusion: A dose 40 mg zinc dispersible tablet, equivalent to 40 mg elemental zinc, given 30 min before surgery, effectively reduced the incidence and severity of POST.
