Recent reports of the incidence of postoperative sore throat following anaesthesia with tracheal intubation have claimed that low volume high pressure cuffs are preferable to those with high volume and low pressure. In this study similar methods were used for evaluating postoperative sore throat. Randomly selected tracheal tubes were used in 56 patients undergoing elective abdominal surgery, followed by direct questioning about sore throat on the first postoperative day. The incidence of postoperative sore throat was 41 per cent with high volume low pressure cuffed tubes and 55 per cent with low volume high pressure cuffed tubes. This difference is not statistically significant, but the tendency of the results is contradictory to those published earlier. The incidence of postoperative sore throat varies greatly if direct or indirect questioning is used and also varies between studies using the same method of questioning. Therefore the validity of this method for evaluating the influence of cuff design must be questioned. Postoperative sore throat is a symptom caused by many factors, such as the intubation procedure and the use of stylets or lubricants. The incidence of postoperative sore throat does not necessarily reflect damage caused by the tracheal tube cuff.KEY WORDS: COMPLICATIONS, postoperative sore throat; EQUIPMENT, tracheal tube cuff design.TRACHEAL DAMAGE after long term intubation with permanent severe damage to a small number of patients, led to improvement in cuff design. Interest has then been focused on short term intubation 2-4 and postoperative sore throat 7-9. Postoperative sore throat (PST) is a quantitatively large problem -little but reversible damage to a large number of patients. PST has been evaluated by interviewing patients the day after operation. Wolfson 5 reported an incidence of PST of 18.4 per cent using direct questioning, Hartsell and Stephen 6 5.7 per cent using indirect questioning, while Loeser, et al. 7 had a PST incidence of 24 per cent with low volume cuffs and 58 per cent with high volume cuffs using direct questioning. Loeser, have investigated the relation between PST and cuff pressure, lubricant and cuff-tracheal contact area. They conclude that lubricant and high volume cuffs result in a higher frequency of PST, the best results being achieved with unlubricated low volume high pressure cuffs. These findings are in opposition with

“…Many studies [1,4,7,[11][12][13][14][15][16] said that female patients tend to have more sore throat. This correlates with the higher incidence of contact ulcer and granuoma formation found in the females [1,12].…”

“…Many studies have found that the incidence of postoperative sore throat did not correlate with the age of the patient [6,11,14,18,20]. But Sprague et al [19] have found that the postoperative sore throat incidence was greater in the under forty age group than in the older group.…”

“…Among the patients who did not have predisposing causes, symptoms (sore throat and hoarseness) arose in 37% in a study done by William Hamelberg [10]. Mechanism contributing to postoperative sore throat are [11] a) Trauma to the tonsillar pillars, pharynx, tongue, larynx and trachea b) Oedema in the structures of the nasal cavity when this route of intubation is used c) Drying out of mucosal membranes in the trachea with endotracheal intubation of upper airway following anaesthesia by facemask.…”

“…b) Bulkier and larger low pressure tubes produce more damage to upper airway structures on intubation or extubation c) Low pressure high volume tube cuffs produce grooves in the mucosa because of wrinkling of the cuffs as it is inflated, unlike the inflation of high pressure low volume cuffs [16].

Objective: To assess the incidence of sore throat and hoarseness caused by endotracheal intubation. To observe if lignocaine or dexamethasone throat spray would alter the incidence of sore throat Materials and methods: Adult patients of either sex who underwent general anaesthesia with endotracheal intubation were included in this randomised double blind study. Three hundred patients who had general anaesthesia with endotracheal intubation were randomly allocated into three groups -Group A, Group B and Group C following block randomisation. Nature of the study was explained to the patient and verbal consent obtained. Group A -2ml of dexamethasone (8mg) was sprayed Group B -2ml of 4% lignocaine was sprayed in this group. Group C -2ml of normal saline was used in this group. Postoperatively between 12-24 hours patients were invited to find out if any sore throat or hoarseness of voice was present. Verbal analogue scoring system was used. Results: Postoperatively sore throat was present in 26% in group A, 33% in group B and 28% in group C. Hoarseness was present in 20% in group A, 23% in group B and 18% in group C. Sore throat and hoarseness were present in 37% in group A, 45% in group B and 39% in group C. Conclusion: Neither dexamethasone nor lignocaine throat spray were useful in reducing postoperative sore throat and hoarseness.
