title: Hyperglycaemia and ketosis in a non-diabetic patient--an unusual cause of delayed recovery.
abstract: We report a case of hyperglycaemia and ketosis developing in a non-diabetic patient who underwent a neurosurgical procedure under general anaesthesia. A 52-year-old non-diabetic female patient underwent excision of acoustic neuroma under general anaesthesia. Pancreatic function was not disturbed and she received a single dose of dexamethasone (8 mg) and paracetamol (1 g). Delayed recovery from anaesthesia occurred. On investigation, she was found to have hyperglycaemia and ketosis. She was further managed on the line of diabetic ketoacidosis. After 24 hours, when blood glucose had normalised and ketosis abated, she could be weaned from mechanical ventilation and extubated. The patient did not receive any drugs known to cause such a condition. To the best of our knowledge, hyperglycaemia and ketosis developing in a non-diabetic patient causing delayed recovery and extubation is here reported for the first time.
