Abstract

Objectives: Postoperative sore throat is a common complication during recovery period which may cause patients’ discomfort and dissatisfaction. Several factors were reported to affect the incidence with types of airway management (LMA or ETT) being the most recognizable factor. Hence, the objective is to compare the incidence of sore throat by using LMA and ETT with association of other factors.

Methods: In this prospective observational cohort study, 40 patients with scheduled surgery were enrolled into the research. Before the surgery, patient’s related factors such as age, gender and smoking status were obtained. During the surgery, the patient will be stratified either under LMA or ETT group and duration of intubation was noted. 24 hours after the surgery, a set of questionnaire will be filled by the patient to determine whether the patient develops sore throat or not.

Results: Out of 40 patients, 22.5% suffered from sore throat after the surgery. The LMA group has a higher percentage of incidence (28.6%) compared to ETT (15.8%). Female patients reported more sore throat than male patients (33.3% vs. 13.6%). Postoperative sore throat was observed to be more common in smoking patients, age group older than 45 years old and duration of anesthesia less than 60 minutes.

Conclusion: Awareness of the factors responsible for increased incidence of postoperative sore throat and appropriate care especially when choosing the types of airway management can help to reduce the incidence of postoperative sore throat and ultimately lead to higher patient’s satisfaction.
