Compare The Hemodynamic Parameters Using Magnesium Sulphate and Tramadol as Adjuvants to Intrathecal Hyperbaric Bupivacaine in Subarachnoid Block

Background: Spinal anesthesia is a type of regional anesthesia achieved by obstructing the spinal nerves roots within the subarachnoid space through the injection of a local anesthetic solution into the cerebrospinal fluid, mostly affecting the spinal nerve roots. The objective is to evaluate the safety and effectiveness of intrathecal hyperbaric bupivacaine in subarachnoid block utilizing magnesium sulfate and tramadol as adjuvants in terms of hemodynamic parameters and potential adverse effects. Material and Methods: Eighty patients with ASA I/II physical status undergoing elective infraumbilical procedures were randomly divided into two groups and administered one of the following subarachnoid blocks: 1. Group M (n = 40) 50 mg of magnesium sulfate and 2.5 ml of bupivacaine (0.5% H). 2. Group T (n = 40) Tramadol 25 mg and Bupivacaine (0.5% H) 2.5 ml. Side effects and hemodynamic parameters were noted Results: There was a significant fall in intraoperative Blood pressure in Tramadol group compared to Magnesium group. But this did not require any intervention. Other hemodynamic parameters were comparable between two groups. There was no significant difference in the degree of sedation between two groups. Conclusion: Intrathecal Magnesium Sulphate is a better adjuvant than intrathecal Tramadol as it provides no significant hemodynamic variations and side effects.
