Abstract
Background: Post-operative complications of sore throat, cough and hoarseness of voice are common minor complications following general anaesthesia. Although with a lower incidence with the use of supraglottic device, they may cause discomfort and delay recovery which may lead to added hospitalization costs. To date, while there are proposed methods to prevent them, there is yet to be a proven method to effectively reduce their incidence and severity. This study evaluates the effectiveness of a single preoperative dose of nebulized dexamethasone to reduce the incidence and severity of post-operative sore throat, cough and hoarseness of voice in the use of Ambu® AuraGainTM device. Methods: 24 patients between ages 18-70 of ASA 1 and 2 groups undergoing elective surgical procedures using supraglottic airway device in Hospital Universiti Sains Malaysia, Kelantan were recruited and assigned randomly to 2 groups either C for routine anaesthetic care (n=12), or D for receiving intervention (n=12). Outcomes of incidence and severity were measured using a 4-point scale for post-operative sore throat, cough and hoarseness of voice respectively at 1 and 24 hours Results: The incidence of sore throat was lower at 24 hours in the control group compared to the intervention group (8.3% vs 50% p = 0.045). Incidences of cough and hoarseness of voice were higher at 24 hours in the intervention group, but this was not statistically significant. Conclusion: Pre-operative nebulized dexamethasone 8mg was not effective in reducing the incidence and severity of post-operative sore throat, cough and hoarseness of voice following the use of device.
