title: Epidural analgesia in high risk cardiac surgical patients.
abstract: Cardiac surgery is associated with high morbidity and mortality in patients with renal, hepatic or pulmonary dysfunction, advanced age and morbid obesity. Thoracic epidural analgesia is associated with decreased morbidity in these patients. Thoracic epidural analgesia in cardiac surgery is associated with haemodynamic stability, decreased catecholamine response, good pulmonary function, early extubation and discharge from intensive care unit. It is an important component of fast tracking in cardiac surgery as well. Its use has significantly increased over the years and has been used as an adjuvant to general anaesthesia as well as the sole anaesthetic technique in selected groups of patients. Proper selection of patients for thoracic epidural analgesia is mandatory. Timing of epidural catheter insertion and removal should be judiciously selected. The risk of epidural hematoma secondary to anticoagulation or residual effects of antiplatelet drug that can be reduced by taking standard precautions. In conclusion thoracic epidural analgesia in high risk cardiac surgery might decrease pulmonary, cardiovascular or renal complications, provide excellent analgesia and allow early extubation.
