Study summary

Good quality of postoperative analgesia would lead to attenuate or prevent the adverse effects on the common functions of the immune system. We compared the effect of epidural analgesia versus rectus sheath block on postoperative pain and proinflammatory cytokines following malignant urological surgery.

Read the detailed description

Study groups: 60 patients were included in the study randomly allocated into two groups of 30 patients. Rectus sheath group (RSB): Each patient received bilateral single shot ultrasound guided rectus sheath block under complete aseptic condition in a dose of 30 ml of bupivacaine 0.25% in each side immediately after induction of general anaesthesia. Control group: the patients did not receive any intervention after anaesthesia induction.
