Lower Limb Surgeries
Conditions
Brief summary
This study aim is to compare height based dose of spinal anesthesia vs conventional dose. Hypothesis is height based dose has less hemodynamics changes compared to conventional dosing.
Detailed description
This is a prospective, randomized, double blinded, controlled trial with minimum 6 months of data collection. Patients will be divided into two groups randomly. Group H and C each having 52 patients. Groups H will be given spinal anesthesia dose according to their height by pre determined dosing algorithm. Group C will be given a fixed dose of Hyperbaric Bupivacaine 0.5% 12.5mg (2.5ml) without adjusting it according to their height. Pateint's blood pressure and Heart rate along with sensory effect will be recorded 5,10 and 15 minutes later after spinal anesthesia. I will be recording any episode of bradycardia and hypotension and intervention needed to treat it in both the groups
