Intervention / Treatment
Detailed Description
Pneumatic tourniquet will be applied on the mid- thigh with cuff pressure of 350 mm Hg. After the end of surgery, the lower limb will be elevated at 45-degree and the patients will randomized into one of the three groups:
G 50 (n=30) : The tourniquet cuff pressure will be deflated gradually by 50 mm Hg every 2 minutes till complete deflation.
G 100 (n=30): The tourniquet cuff pressure will be deflated gradually by 100 mm Hg every 2 minutes till complete deflation.
G 0 (n=30): The tourniquet cuff will be released till complete deflation. If hypotension is observed during the procedure, it will be managed by 10 mg ephedrine.
