Effect of position - Trendelenburg and horizontal on the height of sensory block in patients undergoing lower abdominal surgery

Background: Subarachnoid anesthesia also known as spinal is now considered to be a safe form of for lower abdominal and limb surgeries. The height sensory block achieved in after drug administration can altered by changing the position patient, this precisely advantage using hyperbaric local anesthetic drug. Aims Objectives: aim study compare effect – horizontal Trendelenburg on anesthesia. Materials Methods: After obtaining institutional ethical clearance, total 66 patients scheduled surgery under were selected divided into two groups Group A placed with 20° head down 40 s then returned B level was compared among at different points time up 30 min administration. Results: who remained higher earlier group maximum segments than that group. Conclusion: From our current study, we conclude used achieve successful neuraxial block.
