Comparison Of Effects Of Trendelenburg 20 Degree, Passive Leg Raising At 45 Degree And Supine Position On The Hemodynamic Changes After Tourniquet Deflation In Orthopaedic Lower Limb Surgery Under Spinal Anaesthesia - A Prospective Parallel Controlled Study

It is a Prospective Parallel Controlled Study to Compare the effect of Trendelenburg 20 degree position, Passive leg raising at 45 degree and Supine position on hemodynamic changes after tourniquet deflation in patients undergoing Orthopaedic lower limb surgery under Spinal Anaesthesia. Here patients will be allocated into 3 study group by block randomisation with sealed envelope system. We will prepare fifteen randomly generated treatment allocations within sealed opaque envelopes assigning T, P and C in 5 envelopes each, where T represents Trendelenburg 20degree group, P represents PLR 45 degree group and C represents control group with supine position. Once a patient will consent to enter a trial, an envelope will be opened and the patient will then be offered the allocated group. In this technique, patients will be randomised in a series of blocks of fifteen.After whic hemodynamic parameters will be monitored and recorded at baseline,0,1,2,3,4,5,10,20,30 minutes and need of vasopressors and IV fluid usuage, Torniquet inflation and Deflation time will be recorded.
