    Background: The unique positioning of the patient at steep Trendelenburg with prolonged and increased intra-abdominal pressure (IAP) during robotic radical prostatectomy may increase the risk of splanchnic ischemia. We aimed to investigate the acute effects of IAP and steep Trendelenburg position on the level of ischemia modified albumin (IMA) and to test if serum IMA levels might be used as a surrogate marker for possible covert ischemia during robotic radical prostatectomies. Patients and Methods: Fifty ASA I-II patients scheduled for elective robotic radical prostatectomy were included in this investigation. Exclusion criteria: The patients were excluded from the study when an arterial cannulation could not be accomplished, if the case had to be converted to open surgery or if the calculated intraoperative bleeding exceeded 300ml. All the patients were placed in steep (45 degrees) Trendelenburg position following trocar placement. Throughout the operation the IAP was maintained between 11-14mmHg. Mean arterial blood pressure (MAP), cardiac output (CO) were continuously monitored before the induction and throughout the surgery. Blood gases, electrolytes, urea, creatinine, alanine transferase (ALT), aspartate transferase (AST) were recorded. Additionally, IMA levels were measured before, during and after surgery. Results: (1) MAP, CO, lactate and hemoglobin (Hb) did not significantly change in any period of surgery (p>0.05)

    Background. Intravenous patient-controlled analgesia (IV PCA) using opiods is an accepted method for delivering postoperative analgesia. The aim of this study was to compare fentanyl and tramadol with IV PCA after spinal anesthesia (SA) and general anesthesia (GA) following cesarean section (C/S). Methods. Ninety women were randomly assigned to three groups (n=30). Group 1 was treated with IV fentanyl PCA after SA. Groups 2 and 3 were treated with IV fentanyl PCA and IV tramadol PCA after GA. Outcome measures were recorded for the first 24 h post-anesthesia. Results. PCA use was significantly lower after SA (P<0.05). Eighteen patients in the SA Group and 27 patients and 24 patients from the GA groups required additional opioid. Opioid consumption and patient satisfaction were similar for groups after GA (P>0.05). 638.4 +/- 179.1 mu g fentanyl was consumed by patients of Group 2, 356.3 +/- 87.0 mu g fentanyl and 559.5 +/- 207.0 mg tramadol was consumed by Group 1 and Group 3 respectively. There was no significant difference in the overall severity and incidence of nausea, drowsiness or pruritus. Conclusion. Our study shows that analgesic consumption and post-operative pain scores after SA in C/S decreased, without increase in adverse reactions.
