Study Objective |
To examine postoperative sore throat resulting from tracheal intubation stylet removal.
Design |
Prospective cohort study.
Setting |
Operating rooms and hospital ward.
Patients |
A total of 50 American Society of Anesthesiologists physical status 1 and 2 patients who underwent elective abdominal and/or orthopedic surgery under general anesthesia.
Interventions |
Patients were allocated to 2 groups: those who developed sore throat postoperatively (ST group) and those who did not (NST group). Comparative analysis of these 2 groups was performed to identify risk factors of the development of sore throat.
Measurements |
The extraction force during stylet removal was measured using a force measuring device. Postoperative sore throat was assessed by an anesthesiologist.
Main Results |
Nine patients (18%) complained of postoperative sore throat. Increased extraction force (P=.0054; odds ratio, 1.84; 95% confidence interval, 1.20-2.84) was the only significant risk factor for the development of postoperative sore throat. An extraction force of >10.3N was determined as a cutoff for developing postoperative sore throat.
Conclusion |
Postoperative sore throat was significantly related to increased extraction force during stylet removal.

Highlights |
• | We investigated risk factors for postoperative sore throat after tracheal extubation with using novelty measurement. |
• | Postoperative sore throat was significantly related to increased extraction force during stylet removal. |
• | Especially, extraction force during stylet removal >10.3N correlated postoperative sore throat. |
