Official title
Comparison of Hemodynamic Effects of Fractionated Dose Versus Bolus Dose of Hyperbaric Bupivacaine (0.5%) in Spinal Anesthesia for Lower Limb Surgery
Overview
To assess hemodynamic changes with hyperbaric bupivacaine with spinal anesthesia
Detailed description
Assesment of hemodynamic changes like heart rate and blood pressure with hyperbaric bupivacaine in spinal anesthesia when given in fractionanted versus bolus dose manner
Interventions
- Drug Spinal Anesthesia (bupivacaine)
In this group B spinal Anesthesia will be given in one single shot - Drug Spinal Anesthesia (bupivacaine)
In this intervention spinal Anesthesia of bupivacaine will be given in a fractionated manner that is 2/3 of dose initially and then 1/3 after 90 seconds
Primary outcome measures
- Mean Arterial Pressure [Time frame: Baseline and up to 120 minutes]
Secondary outcome measures (2)
- Hypotension and bradycardia [Time frame: Baseline and up to 120 minutes]
- Requirement of vasopressors [Time frame: Baseline and up to 120 minutes]
