A COMPARATIVE STUDY OF ENDOTRACHEAL TUBE CUFF PRESSURE MONITORING TO PREVENT POST-OPERATIVE INTUBATION RELATED COMPLICATIONS WHEN NITROUS OXIDE IS USED AS A CARRIER GAS IN GENERAL ANAESTHESIA
The laryngotracheal morbidity is frequent after tracheal intubation even with short duration of general anesthesia. Following tracheal intubation, sore throat and hoarseness of voice is the most common chief complaints of the patients. However sometimes even more than postoperative pain these symptoms become even worse when nitrous oxide is used as one of the carrier gas in general anesthesia procedure. It is surprising that there is a limited research has carried out this area before. In this
... roximity the present study aims to evaluate the efficacy of peri-operative cuff pressure monitoring in decreasing the incidence of postoperative intubation related complications like sore throat, hoarseness of voice, cough, dysphagia, stridor, and severity of sore throat by V.A.S scale after orotracheal intubation under general anesthesia. A randomized double blind controlled prospective study conducted after the approval by the institutional ethics committee on 60 patients between 20-70 years of age divided into two groups. The Group A (Naïve) and Group B (Placebo-group)the cuff pressure obtained by the minimal leak test was noted as baseline pressure the cuff pressure were obtained by the minimal leak test was not been altered by inflating or deflating the cuff. As per the results the incidence of hoarseness (p<0.001) incidence of sore throat (p<0.001), incidence of cough (p<0.001), incidence of Dysphagia (p<0.001), severity of sore throat by VAS scale (p<0.001) was found to be statistically significant when compared to the placebo group. The present study concludes that there was lower incidence of hoarseness of voice, sore throat, severity of sore throat by VAS scale, cough and dysphagia in study group when compared to control group, which is attributed to, continuous monitoring and maintaining the cuff pressure by either inflation or deflation and keeping the cuff pressure at the basal level.
