Postoperative Sore Throat with Foam Cuffed Endotracheal Tube

Background: Postoperative sore throat is the most common and most distressing complaint of patients after general anaesthesia with cuffed endotracheal tube. By this study our aim was to assess the efficacy of intracuff dexamethasone in reducing the incidence of this distressing postoperative symptom.Methods: Patients were divided into two groups D and N depending on cuff filling with dexamethasone and normal saline respectively. The cuff was prefilled with dexamethasone or normal saline one hour prior to intubation to allow time for cuff to be saturated following which the cuff was deflated. General anaesthesia was administered and patients were intubated, and cuff inflated with drug according to group allocated. Patients were assessed and graded for sore throat using VAS scale both at rest and with swallowing. Assessment was done one hour, six, 12 and 24hours post operatively. Presence of hoarseness of voice and cough was assessed on a 2-point scale 0=absent and 1=present, 24hrs after surgery.Results: The incidence of sore throat at 24hours postoperative was reduced in group D than in group N. 4 patients (8%) in group D had sore throat while 27 patients (57%) in group N had sore throat at 24hours. This was statistically significant (p<0.05). The cough incidence was reduced in group D while there was no difference in incidence of hoarseness of voice between the two groups.Conclusions: Intracuff dexamethasone decreases the incidence of postoperative sore throat when compared to intracuff normal saline. Dexamethasone also reduces postoperative cough incidence but does not reduce the incidence of hoarseness of voice.

A Prospective Study

A prospective study was carried on 120 patients undergoing surgical operations lasting less than 90 minutes. The incidence of postoperative sore throat, dysphasia and hoarseness of voice with 2% lidocaine (Group L) as endotracheal cuff inflating agent was compared with that with distilled water (Group D) and air (Group A). Seventy two percent of lidocaine group in comparison to 60% distilled water group and 37% air group experienced none of the above complications during the entire study period. Only 5% in lidocaine group had sore throat after 22-24 hours compared to 20% in the distilled water group and 45% in the air group. Twenty three percent complained of dysphasia in both lidocaine and distilled water group after 1-3 hours compared to 45% in air group. After 22-24 hours it completely resolved in lidocaine group compared to 20% persisting in the other two groups. Twenty three percent complained of hoarseness in lidocaine group as compared to 35% and 55% in distilled water and air groups respectively after 1-3 hours. This completely resolved in lidocaine group but persisted in 20% and 45% in the distilled water and air group respectively after 22-24 hours. The results showed an advantage in using lidocaine as an endotracheal tube cuff inflating agent in reducing postoperative sore throat, dysphasia and hoarseness in comparison to distilled water and air.

Dexamethasone Group

Introductions: Postoperative sore throat (POST) is a commonly seen adverse event after general anesthesia with endotracheal intubation. Dexamethasone, a potent corticosteroid with anti-inflammatory action is the most popular steroid studied in this regard with positive results. Methods: This randomized, prospective, double-blinded, placebo-controlled study was conducted on one hundred and ten adult patients of either sex, American Society of Anesthesiologists physical status I & II, undergoing elective surgeries requiring endotracheal tube intubation. After obtaining written informed consent, they were randomly divided into Control (A, n=55) and Dexamethasone (B, n=55) groups and received either an injection of Dexamethasone (Group B) 8 mg intravenously or an equivalent volume of Normal Saline (Group A) just before entering the operating theatre. All the patients received a similar anesthesia with endotracheal tube intubation and at the end of surgery, extubated and transferred to the post-anesthesia care unit. The incidence and severity of sore throat were assessed at 1, 6 and 24 hours post-extubation. Severity of sore throat were graded on a 4 point scale, p <0.05 was considered significant. Results: Incidence of POST in Dexamethasone group was found significantly low compared to the control group up to six hours (p<0.05) but was comparable at 24 hours post extubation. Severity of POST in the study group was of lower grade in compare to control group. Conclusions: Prophylactic intravenous Dexamethasone 8 mg administered to patients undergoing elective surgeries requiring endotracheal tube intubation significantly reduces the incidence and severity of POST up to six hours post-extubation.
