Sanjit
70, Male

Sanjit Patel is a 70 year old man who is a retired accountant.

He was admitted 4 days ago for elective coronary artery bypass grafting for triple vessel coronary artery disease. He underwent the procedure 3 days ago which was complicated by intra-operative hypotension and post-operative bleeding requiring a return to theatre. He was transfused 4 units of blood in total.

For the last 24 hours his urine output has been falling and he has only passed 5-10 ml/hr for the past 4 hours which is why you have been asked to see him.
