Negative Pressure Pulmonary Oedema (NPPO) is an uncommon, potentially life-threatening complication of general anesthesia. It is said to even be less common with the use of a laryngeal mask airway (LMA).Mortality can be as high as 11 -40%. We present a 31 year old man who presented for emergency appendectomy under general anaesthesia with LMA who was managed in the ICU with judicious use of frusemide and positive pressure ventilation and was subsequently discharged after 48 hours.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
