Trendelenberg Positioning Technique, An Alternative to Preloading for prevention of Hypotension during Spinal Anaesthesia for Abdominal Hysterectomy

Aims: The study was undertaken to search for an alternative technique to preloading with less or no side effects. Settings and Design: A total of 100 female patients of ASA class I and II undergoing abdominal hysterectomy were enrolled in the study. Two groups namely Group A and Group B were made. All the patients received 2.6ml of 0.5% Bupivacaine heavy intrathecally at L3-L4 level in lateral decubitus using 25 gauge Quincke's spinal needle. Patients of Group A were placed in Trendelenberg position after spinal anesthesia and patients of Group B received preloading with Lactated Ringer's solution before spinal anaesthesia. Assessment of hemodynamics (intraoperative and post operative) and side effects was done. Statistics: Data are expressed as mean + SD. Group comparisons were made using unpaired t-test. Results: Intraoperative blood loss and intraoperative requirement of Inj. Mephentermine was significantly less in Group A in comparison to Group B. Conclusion: Trendelenberg positioning after spinal anesthesia could be advantageous in terms of intraoperative vasopressor requirement and introperative blood loss.
