Evaluation of the analgesic efficacy of a low dose of intrathecal morphine in laparoscopic abdominal surgery: A randomised control trial.

Introduction: Intrathecal opioid is an analgesic option in laparoscopic surgery. We assessed primarily the intraoperative opioid requirement amongst patients receiving intrathecal morphine (ITM) (Group M) versus standard care (Group C) for abdominal surgery. The secondary outcomes were intraoperative haemodynamic changes, extubation on table and pain scores in the intensive care unit (ICU) at 6 th hourly intervals for 24 h postoperatively.

Does the resistive index of the radial artery change after arterial cannulation in patients undergoing abdominal surgery? A prospective observational study.

Background And Aims: To evaluate the flow at the cannulation site in the radial artery, the resistive indices (RIs) before cannula insertion and 6 h after decannulation were measured (primary outcome). The secondary outcomes were measurement of the artery size by anteroposterior (AP) diameter at the insertion site, RI and AP diameter at a point 4 cm proximal and in the ipsilateral ulnar artery before insertion and 6 h after cannula removal.

Methods: In 96 patients requiring an arterial line during surgery, peak systolic velocity (PSV) and end-diastolic velocity (EDV) were measured to derive RI using a linear ultrasound transducer.

Comparison of arterial to end-tidal carbon dioxide gradient P (a-ET)CO in volume versus pressure controlled ventilation in patients undergoing robotic abdominal surgery in the Trendelenburg position. A randomised controlled study.

Background And Aims: Robotic surgery is increasingly prevalent as an advancement in care. Steep head-down positions in pelvic surgery can increase the ventilation-perfusion mismatch and increase ventilatory requirements to offset carbon dioxide (CO) increases consequent to pneumoperitoneum. The primary objective was to assess the impact of two ventilatory strategies, volume versus pressure-controlled ventilation on the arterial to end-tidal carbon dioxide gradient P (a-ET)CO in patients undergoing robotic surgery in the Trendelenburg position.

Role of Ulinastatin, a trypsin inhibitor, in severe acute pancreatitis in critical care setting: A retrospective analysis.

Purpose: To evaluate the clinical utility of Ulinastatin, a multifunctional serine protease inhibitor, in the management of severe acute pancreatitis.

Materials And Methods: We conducted a retrospective analysis of the archived data of adult patients diagnosed with acute pancreatitis and admitted to surgical intensive care unit with one or more end organ dysfunction. The patients were divided into two groups depending on whether they did or did not receive ulinastatin.
