Abstract
ObjectivesPostoperative sore throat (POST) is very common in patients under general anaesthesia. However, there is no effective clinical predictive model for reducing its occurrence. The objective of this study was to estimate the risk factors for POST in patients after general anaesthesia by designing a nomogram.DesignA prospective study.SettingThis study was conducted in a large tertiary hospital.ParticipantsPatients aged 18–85 years old who received general anaesthesia with either an endotracheal tube or supraglottic airway and of American Society of Anesthesiologists classification level Ⅰ–III.ResultsA total of 442 patients were enrolled in this study, with a POST incidence of 44.1%. The results showed that younger age (≤55 years), surgical site (head and neck surgery), duration of anaesthesia (≥4 hours) and history of chronic pharyngitis were independent risk factors for POST in general anaesthesia patients. Receiver operating characteristic (ROC) curves and calibration curves were used to evaluate the nomogram. The area under the ROC curve was 0.784 and the C-index was 0.779.ConclusionA nomogram combining age, surgical site, duration of anaesthesia and history of chronic pharyngitis is potentially useful in predicting POST under general anaesthesia.Trial registration numberChiCTR-ROC-17013258; Post-results.
