PIG Meeting: 11th February 2021
- Sestamibi preop (organized by vascular surgeons) – normal EF and nil ischaemia
- Uneventful procedure, short clamp time
- EDB functioning well, extubated, transported to ICU, doing well
- ~3am developed shock + respiratory failure
- Reintubated, NAd and vasopressin commenced
- Cause of shock difficult to establish
- CT showed no bleeding, all vessels perfused, some small areas of gut ischaemia but not thought significant enough to cause the degree of shock
- Bedside TTE – difficult views but nil obvious cause of severe shock
- Fluid responsive with lactate dropping from 9 to 5 with fluid resus
- Surgical team reluctant to take patient to OT for a re-do laparotomy which they believed was likely to be non-diagnostic.
- Patient eventually taken to OT – ischaemic colon and 2m of small bowel – resected, abdo left open
- Patient survived with AKI
- Discussion involved consideration of immediate postoperative complications needing surgical complication to be excluded. This case shows the important of looking to the obvious, common causes of shock in a patient after major surgery.
- Discussion about whether or not a TOE should have been used in this patient while the cause of shock was still unclear. The clinician felt that the limited TTE views obtained were adequate to exclude a cardiac event as a cause of shock, at least while the most likely source (an intra-abdominal complication) was still being investigated.
- Acknowledged that re-look laparotomies have an accepted false negative rate, in order to avoid missing the opportunity for life-saving intervention.
