Summary

The purpose of this study is to assess and contrast the effectiveness of intravenous ondansetron and intravenous hydrocortisone in avoiding spinal anesthesia-induced hypotension.

Conditions

  • Post Spinal Anaesthesia Hypotension

Interventions

DRUG

hydrocortisone

A deidentified syringe (10 mL) containing 100 mg hydrocortisone will be given 15 minutes prior subarachnoid blockade. Spinal anesthesia will be performed with a 25-gauge Quincke spinal needle to administer 3.5 ml of a 0.5% hyperbaric bupivacaine plus 25 micrograms of fentanyl at the L3-L4 or L4-L5 level. Then, Patient will lie supine with slight head elevation. Intravenous Infusion of 500 ml normal saline over the initial post spinal 30 minutes. Sensory level and motor block will be verified. Heart rate (HR), systolic (SBP), diastolic (DBP) and mean blood pressure (MBP) will be measured every 5 min for 6 readings during which the patient remains in the supine position with no application of torniquet.

DRUG

ondansetron

A deidentified syringe (10 mL) containing 8 mg ondansetron will be given 15 minutes prior subarachnoid blockade. Spinal anesthesia will be performed with a 25-gauge Quincke spinal needle to administer 3.5 ml of a 0.5% hyperbaric bupivacaine plus 25 micrograms of fentanyl at the L3-L4 or L4-L5 level. Then, Patient will lie supine with slight head elevation. Intravenous Infusion of 500 ml normal saline over the initial post spinal 30 minutes. Sensory level and motor block will be verified. Heart rate (HR), systolic (SBP), diastolic (DBP) and mean blood pressure (MBP) will be measured every 5 min for 6 readings during which the patient remains in the supine position with no application of torniquet.

DRUG

Placebo

A deidentified syringe (10 mL) containing sterile distilled water for intravenous injection will be given 15 minutes prior subarachnoid blockade. Spinal anesthesia will be performed with a 25-gauge Quincke spinal needle to administer 3.5 ml of a 0.5% hyperbaric bupivacaine plus 25 micrograms of fentanyl at the L3-L4 or L4-L5 level. Then, Patient will lie supine with slight head elevation. Intravenous Infusion of 500 ml normal saline over the initial post spinal 30 minutes. Sensory level and motor block will be verified. Heart rate (HR), systolic (SBP), diastolic (DBP) and mean blood pressure (MBP) will be measured every 5 min for 6 readings during which the patient remains in the supine position with no application of torniquet.
