Endotracheal Tube Balloon Under 0./N.O Anesthesıa Increase In Pressure And Its Preventıon
Abstract
Changes of pressure in the endotracheal tube cuffs inflated sither with room air or O,/N,O mixture have been vvmpared in 50 patients under) /N,O anaesthesia. In cuffs inflated with air intracuff pressures increased regardless of the mode of ventilatation and were above the mean capillary pressure in most of the cases, In cvffs inflated with anaesthetic gas mixture intracuff pressures gradualy decreased but only in one case did this necessitate reinflatation. Accordng to these results and the possbility of iscehemic damage to the tracheal wall, cuffs sohould be inflated with anaesthetic gas mixture or if inflated with air they should be deflated and reinflated every hour after careful aspiration or pressure should be monitored continuously with a manometer and adjusted accordingiy.
