Incidence of Post-Operative Hoarseness and Sore Throat between Endotracheal Cuff Is Inflated with Alkalinised Lignocaine Versus Air in Laproscopic Procedures: A Comparative Study

Abstract

Introduction- Airway management with cuffed endotracheal tubes for General Anaesthesia is an integral part of anaesthesiologist’s responsibilities towards patient care.Amongst the sequel inherent to the usage of cuffed endotracheal tubes are local irritation and inflammation of the airway caused by prolonged inflation of the cuff which results in post extubation morbidities like sore throat, hoarseness of voice and cough. Objectives-To compare the incidence of post-operative,sore throat has any relation with age, sex and post-operative nausea and vomiting. Methods-A prospective one-year cross sectional study was conducted in department of Anaesthesiology, Baby Memorial Hospital, Calicut during the period of November 2014 to October 2015.Patients undergoing laproscopic surgeries in surgical, gynaecological and urology under general Anaesthesia at Baby Memorial Hospital were the study population. Patients were divided into two groups. Post-Operative sore throat and hoarseness were calculated on 0,6-hour, 12 hour and 24 hours. SPSS (IBM 22.0) was used for analysis. Chi square test and t test were used as test of significance. Results-the mean age of 32.1 was calculated with a standard deviation of 6.801.Similarly, in the control group mean age of 32.3 was calculated with a standard deviation of 6.990. Among 100 patients taken for the study in the test group ,57 were females (57 %) and 43 were males (43 %). Intervention with alkalinised lignocaine in endotracheal tube cuff is much effective in reducing the incidence of sore throat than air in the cuff. (p<0.001). Out of 100 patients in the test group AL, 82 patients had no Post-Operative Nausea and Vomiting,18 had Post-operative nausea and Vomiting. In the control group A out of 100 patients, 34 had nausea and vomiting post operatively whereas 66 had no such complaints.In Group A ,35 patients had Visual analogue scale of 1,57 had 2,8 had 3. In Group AL out of 100, 50 had Visual analogue scale of 1 and rest 50 had Visual analogue scale of 2. Conclusion- The intervention of using alkalinised lignocaine in endotracheal cuff instead of air in the endotracheal cuff in laproscopic surgeries produces significant reduction in sore throat and hoarseness, when observed over a period of 24 hours.
