Background and Goal of Study: To assess patients' postoperative sore throat, its incidence and risk factors. The study was approved by the local ethics committee.

Materials and Methods: This prospective observational study comprised 1,942 patients after elective surgery who were inquired about sore throat and other complaints on the 1st postoperative day. If sore throat or hoarseness were present they were re-examined on the 3rd postoperative day. Patients with pain persisting until the 3rd day were referred for otolaryngologic examination. Patients from the University Hospital Olomouc departments of surgery, traumatology, plastic and aesthetic surgery, urology and gynaecology were assessed. Patient records from recovery room and wards as well as anaesthetic records were used to find out how demographic data, anaesthetic management and administered drugs affect sore throat. The output data were processed by the SPSS statistical software and compared using relevant statistical tests at a significance level of 0.05.

Results and Discussion: A total of 16.2% of patients had postoperative sore throat on the day of surgery, with various frequencies depending on the type of airway management during general anaesthesia. Sore throat was most frequent after endotracheal intubation (18.3%) and laryngeal mask insertion (12.8%). The lowest rates of sore throat were reported after face mask ventilation (4%). The way of tracheal tube tip preparation prior to tracheal intubation has a prominent influence as well. Both trimecaine jelly and water increased the incidence of sore throat two-fold as compared with the K-Y jelly or no pre-treatment. Gender (p = 0,712), BMI (p = 0,982), anaesthesiologist's experience (p = 0,311), nasogastric tube insertion (p = 0,522) or smoking (p = 0,691) did not influent sore throat markedly.

Conclusion(s): The technique of perioperative airway management and lubricant use during general anaesthesia significantly affect the incidence of postoperative sore throat.
