Is intranasal dexamethasone effective in reducing sore throat following surgery?

Objectives: Postextubation, individuals may experience the discomfort of a sore throat. Our main aim of the study was to investigate if intranasal dexamethasone is successful in reducing postoperative sore throat occurrence.

Materials and methods: The study involved 96 adult individuals who were scheduled for elective eye surgery at Faiz Medical Center, which is affiliated with Isfahan University, between July 2020 and March 2021. The individuals were assigned by chance to two cohorts of 48 people each, with one cohort getting dexamethasone (IND) through the nose and the other cohort getting normal saline (INS) through the nose right after the endotracheal tube insertion. The presence of symptoms such as aching throat, cough, and hoarseness after surgery was recorded and examined with version 23 of the SPSS software.

Results: Upon analysis, it was observed that there were no statistically significant alterations in demographic attributes, tracheal intubation variables, duration of surgery, and postoperative outcomes (P < 0.05). Within the IND cohort, a notable 80.2% decrease in the occurrence of sore throat was noted immediately following the surgical procedure, along with a 34% reduction within the initial 6 hours of hospital stay (P < 0.001). Moreover, dexamethasone also decreased the occurrence of cough and hoarseness by 31.7% and 38.2% during recovery, as well as 19% and 25.4% within the initial 2 h upon admission to the ward (P < 0.001).

Conclusion: The current study showcased the preventive impact of dexamethasone intranasally in decreasing the occurrence of sore throat in the early stages of postoperative period. Nevertheless, its efficacy diminished after 6 h. Furthermore, the intranasal application of dexamethasone exhibited the ability to alleviate hoarseness and cough within the first 2 h following surgical intervention.
