Cardio-pulmonary and Analgesic Effects of Pre-peritoneal VS Epidural Infusion of L-bupivacaine on Abd. Cancer Patients

The epidural catheter will be placed via a paramedian approach as close as possible to the surgical procedure via the inter-vertebral space (from T7 to T10) so that the affected dermatomes of the surgical wound would receive the benefits of bupivacaine infusion

At the end of surgery and after the closure of the peritoneal layer, the catheter will be allocated above the peritoneum within the musculofascial layer and secured to the skin with an occlusive dressing
