Comparison of the effect of two pharyngeal packing methods (wet pack with saline and wet pack with lidocaine) on postoperative sore throat after nasal surgery

Sore throat is a common and unpleasant complication of anesthesia which often occurs after the extubation. This study was conducted to compare the effects of two pharyngeal packing methods (wet pack with saline and wet pack with 1% of Lidocaine) on postoperative sore throat after the nasal surgery.
Sixty patients aged between 18-70 years with ASA I-II-III who were candidates for elective nasal surgery and categorized in two groups were enrolled in this double-blind randomized clinical trial. In the first group dampened gauze with 10 cc/kg was used for pharyngeal packing. Patients underwent general anesthesia with a similar method and after intubation, pharyngeal pack was placed with Magill forceps and in the end of operation before extubation was removed. Amount of sore throat, coughing, odynophagia, hoarseness, laryngeal spasm, nausea, and vomiting were assessed and compared after the extubation.
There weren’t any significant differences between groups in term of weight, height, sex, age, duration of surgery, and type of surgery (p=0.194). Also there wasn’t significant difference in sore throat between the lidocaine and placebo group.
