RESUMO
PURPOSE: Postoperative sore throat (POST) is a frequent postoperative complication. Preinduction budesonide inhalation is effective in POST prevention. However, it requires inhaler equipment and patient cooperation. Budesonide spraying on the endotracheal (ETT) cuff is simple and can be performed on most patients requiring endotracheal intubation. This study aims to compare the effects of budesonide spray and K-Y gel as an ETT cuff lubricant on the incidence and severity of POST. DESIGN: Randomized and triple-blinded study. METHODS: One hundred patients undergoing elective noncardiac surgery were randomly allocated into the budesonide group (n = 50) and the K-Y gel group (n = 50). In the budesonide group, 200 mcg of budesonide was sprayed on the cuff of the ETT. For the K-Y gel group, the ETT cuff was lubricated with K-Y gel. A visual analog scale was used to assess the severity of POST at 2, 6, and 24 hours after surgery. Other complications of tracheal intubation and adverse effects of budesonide were also recorded. FINDINGS: Compared to the K-Y gel group, the budesonide group had a significantly lower overall incidence of POST (30% versus 54%, P = .032) and reduced the risk of POST by 24% (relative risk reduction = 24%, 95% CI, 5.23-42.77, P = .012) as well as the incidence of hoarseness (8.6% vs 34%, P = .001) and cough (0% vs 8%, P = 0.041). No incidence of drug-related side effects was reported in both groups. CONCLUSIONS: Spraying budesonide on the ETT cuff significantly reduces the incidence and severity of POST.
