ABSTRACT
Postoperative complications Postoperatively this man developed acute abdominal pain and became hypotensive with a systolic blood pressure between 55 and 60 mmHg. He was given fluid resuscitation and required noradrenaline to keep his blood pressure elevated. His blood pressure remained low for about 30 minutes before it responded to fluids and vasopressors. He was oliguric. A haemoglobin from the blood gas machine was 5.5 g/dL. He was taken to surgery to repair a leak in the aortic graft and transfused 6 units of blood perioperatively. He remained oliguric for 24 hours until his renal function was repeated on day 3.
