Anaesthesiology perspective on a multidisciplinary approach to optimal perioperative management of a patient with giant peptic ulcer perforation caused by the physiological stress of a thyroid storm necessitating emergent laparotomy.

Thyroid storm is a rare, fatal complication of thyrotoxicosis that necessitates aggressive medical treatment. We present a case of a patient who developed duodenal ulcer perforation as a result of a thyroid storm caused by Graves' thyrotoxicosis. In addition to life-threatening intra-abdominal sepsis complicated by high anion-gap metabolic acidosis, he was found to have severely deranged thyroid hormone levels and clinical features compatible with thyroid storm based on the Burch-Wartofsky Score. Diagnosis and management of such patients with compromised gastrointestinal (GI) tract present a remarkable clinical challenge to the anaesthetist and the intensivists. Multidisciplinary care with rapid preoperative optimisation, careful intraoperative anaesthetic techniques and postoperative care resulted in excellent outcomes. This case report sheds light on how to tailor general anaesthesia to minimise physiological derangement associated with thyroid storm and re-establish homeostasis in patients presenting for emergent surgery, particularly those with GI dysfunction.

Non-diabetic euglycaemic ketoacidosis and rapid weight loss in a post-traumatic surgical patient: is the outré preventable?

To highlight the implications of the metabolic stress response and the role of anaesthesia in attenuating its deleterious effects, we present this extremely rare case of non-diabetic euglycaemic ketoacidosis with rapid weight loss in a post-traumatic surgical patient. Ketoacidosis is the accumulation of ketone bodies in blood and is generally associated with relative or absolute insulin deficiency secondary to diabetes mellitus, sodium-glucose cotransporter 2 inhibitors and extensive fasting. The stress of systemic disease, trauma or surgery in such predisposed patients could precipitate ketoacidosis. Our patient developed high anion gap metabolic acidosis intraoperatively due to ketosis, a potentially life-threatening complication, without any predisposing factors as a result of metabolic stress of major trauma and surgery. Aiding the interpretation, he lost 15 kg weight perioperatively, suggesting his body was in a hypercatabolic state. This report emphasises the value of anaesthetic techniques to prevent such rare complications.
