Abstract
ABSTRACT
Background
Postoperative sore throat is a relatively minor complaint but a frequent postoperative
complication of anesthesia. The incidence of postoperative sore throat varies from
0-50% in most research studies, but some report the incidence is as high as 51-100%
following general anesthesia.
Objective
The aim of this study was to obtain the incidence and determine the associated risk
factors of postoperative sore throat in tertiary care hospital.
Method
Three hundred and seventy six patients who underwent various surgeries under
general anesthesia in Dhulikhel Hospital during a four month period were included.
Using a predesigned questionnaire with follow up after 24-30 hours after extubation,
data was collected. Sore throat was identified using a four point scale (0-3).
Result
Overall incidence of postoperative sore throat was 50.8%. Patient with airway device
endotracheal tubes had the highest incidence (52.2%, 176 of 337), and patient with
i-gel had a lower incidence of sore throat (33.3%, 7 of 21). Female patients reported
more sore throat than male, more common with older age group and duration of
anesthesia more than two hours. Increased incidence of postoperative sore throat
was not associated with the type of surgery, number of intubation attempts, category
of personnel performing airway managementr and use of oropharyngeal airway.
Conclusion
Postoperative sore throat is a common complication of airway instrumentation in
general anesthesia that can lead to discomfort. The overall incidence of postoperative
sore throat in this study was 50.8%. Endotracheal tube, female patients and increased
duration of anesthesia were associated with increased postoperative sore throat
rates.
