Abstract
this prospective study was designed to assess the plasma concentration of interleukin-6 and gastric tonometric variables compared with global haemodynamic values undermining outcome after elective major abdominal surgery. also examine the effects of intra-abdominal pressure with its circulatory effects on gastric tonometric variables in patients undergoing elective laparoscopic colectomy. the study was performed on twenty six patients of either sex asa i or ii submitted for elective major abdominal and laparoscopic surgeries exclusion criteria were patients with coagulation disorders, cardiac, respiratory diseases patients were allocated into two groups: 1- elective major open abdominal surgeries (20 patients) 2- elective laparoscopic colectomy (6 patients) all patients were monitored by continuous electrocardiography, pulse oxymetry, capnogaphy and blood pressure intraoperative monitoring of vital signs (blood pressure, heart rate, oxygen saturation and end tidal co2 were recorded through out the perioperative period. blood gases, gastric tonometry , il-6 also were recorded through the perioperative period. postoperative complications also were recorded through patient follow up after surgery till the discharge from the hospital. from this study it can be concluded that tonometric variables have a predictive value on the postoperative complications. also laparoscopic colectomy operation with pneumoperitonium around 12 mm hg did not cause any detectable disturbances in splanchnic perfusion using gastric tonometric measurements as evidenced by the absence of postoperative complications
