Abstract [en]

Background: Sore throat following endotracheal intubation is a common problem following surgery and one of the factors that affects quality of recovery. This study was done with the primary aim of assessing whether the size of the endotracheal tube (ETT) affects the risk of sore throat in women following anaesthesia.

Methods: One hundred healthy adult women undergoing elective surgery were randomly allocated to oral intubation with either ETT size 6.0 or 7.0. Anaesthesia was based on either inhalation or total intravenous anaesthesia according to standardized routines. Pre- and postoperatively sore throat and discomfort was assessed on a four-graded scale and for hoarseness on a binary scale (yes or no). Postoperatively the assessments were made after 1-2 hours, 24 hours and if discomfort at 24 h, a follow-up call was made at 72 and 96 hours.

Results: After 1-2 hours postoperatively there were a higher proportion of patients with sore throat in ETT 7.0 versus ETT 6.0 (51.1 % vs. 27.1 %), p= 0.006. When comparing changes between the pre- and postoperative values, this difference between the groups was also evident, p= 0.002. The severity of discomfort from sore throat was also higher in ETT 7.0 (38.8 %) compared to ETT 6.0 (18.8%), p=0.02. No differences were found in the incidence of hoarseness between the groups. Remaining symptoms lasts up to 96 hours postoperatively in 11 %, irrespectively of tube size.

Conclusion: To use a smaller size of the endotracheal tube can alleviate women’s suffering from sore throat and discomfort at the PACU.
