Negative Pressure Pulmonary Oedema Following Emergency Appendectomy under LMA: A Case Report

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.
