Abstract

During adeno-tonsillectomies performed under general anaesthesia with N2O we observed and measured a serious increase in middle-ear pressure (M.E.P.). This is due to the fact that the rate of diffusion of N2O is greater inwards than outwards. This rise in the middle-ear pressure is due to the packing of the nasopharynx after adenoidectomy for haemostasis.
