Changes in Endotracheal Tube Cuff Pressures and Incidence of Post-operative Sore Throat While using different Inflating Agents
Background & Aims: Post-operative sore throat is one of the minor complications after general anaesthesia with endo tracheal intubation. Although short lasting and self-limiting, it creates an uncomfortable situation for patient. Diffusion of Nitrous Oxide (N20) into endotracheal tube (ETT) cuffs and increase intra cuff pressure causes this. Different inflating agents have been studied to see the incidence of intra cuff pressure changes. This study was performed to see the post extubation tracheal mucosal changes and post-operative sore throat after using N20 in Oxygen as ETT cuff with direct visualization of the tracheal mucosa just after tracheal extubation.
