13	41	F	4	Emergency	Spinal	Left Above Knee Amputation and debridement of right below knee stump	Left leg gangrene Non-ST Elevation Myocardial infarction (NSTEMI) Septic shock on dopamine End Stage Renal Failure (ESRF) on Haemodialysis, Chronic Anaemia, Diabetes Mellitus (DM), Hypertension (HTN), Hypothyroidism	PEA post spinal anaesthesia Intubated and surgery proceeded under GA Death in intensive care unit 12 hours post-surgery
14	73	M	3	Emergency	Spinal	Forefoot amputation	Recent NSTEMI with Left foot gangrene DM, Dyslipidaemia, Depression	Intra-operatively haemodynamically stable, an uneventful course in recovery, asystole arrest in general ward 3 hours after.
15	53	M	3	Emergency	Peripheral nerve block	Debridement of forearm	Forearm thrombophlebitis Ischaemic cardiomyopathy, Chronic renal impairment, DM	Developed hypotension in the ward 3 hours post op, Had NSTEMI and hemothorax from block Developed PEA in ward

17	69	M	4	Emergency	Peripheral nerve block	Above knee amputation	Sepsis from Below knee amputation stump wound infection NSTEMI complicated by congestive cardiac failure, DM, HTN, Dyslipidaemia, Carotid artery stenosis, Cervical Myelopathy	Required conversion to GA due to pain. Developed ST elevation intraoperatively, followed by PEA
18	69	M	3	Elective	General	Anterior corpectomy and drainage L2/L3 abscess	Salmonella L2-L4 Osteomyelitis with psoas abscess	Septic patient with new ischaemic ECG changes before surgery Prolonged surgery complicated by blood loss of 2.3 L PEA at end of surgery.

20	65	M	3	Elective	General	Pneumonectomy	Left Lung Adenocarcinoma HTN	Pulmonary artery injury during pneumonectomy Attempted going onto cardiopulmonary bypass however difficulty going onto full bypass in lateral position. Thoracotomy incision also made a sternotomy incision difficult. Repair attempted as mass closure and protamine given but friable tissue and advanced cancer thus bleeding continued.
