简要总结
Spinal anaesthesia is frequently used routine anaesthesia practice. Spinal induced hypotension is most common effect of spinal anaesthesia and in this study we are evaluating the efficacy of preoperative sonographic measurement of internal jugular vein cross sectional area in supine and trendelenburg position for predicting post spinal hypotension in patients undergoing orthopaedic surgeries.
