[Unexpected hemodynamic depression after induction of anaesthesia]

Patients with coronary artery disease (CAD) undergoing noncardiac surgery (NCS) pose a special challenge for the anaesthesiologist, as the risk of serious perioperative cardiac complications, which represent a significant cause of morbidity and mortality, is increased in this population. Here we report about a patient with a solitary liver metastasis, who was admitted for hemihepatectomy. The patient with a known single vessel CAD, reporting no current cardiac problems, was cleared for the surgical procedure which carries a high risk of cardiac complications. Cardiology reports were present for evaluation. After an unremarkable placement of the peridural catheter and endotracheal intubation the patient presented with bradycardia and hypotension. Pharmacological resuscitation was initiated. After the patient was stabilized and the differential diagnosis suggested a cardiac problem, surgery was postponed. Following the end of anaesthesia, the patient remained in stable condition without catecholamine support. Coronary angiography on the next day revealed a progression of the CAD. The peridural catheter was removed before the intervention, Aspirin and clopidogrel were given on the same day. The patient was operated successfully without complications six weeks after the coronary intervention.
