The Impact of Adding Magnesium Sulfate to Bupivacaine versus Bupivacaine Alone in Fascia Iliaca Compartment Block in Burn Patients Undergoing Skin Grafting Procedures; Comparative Study

Abstract

Purpose: The purpose of the study is to evaluate the analgesic effect of adding magnesium sulfate to bupivacaine in Fascia Iliaca Compartment Block (FI-CB). Patients and Methods: Ninety-six burn patients scheduled for skingrafting procedures were allocated into two equal groups. After induction of general anaethesia, forty-eight patients received US guided FICB using 35 ml bupivacaine 0.25% + 5 ml isotonic sodium chloride solution with a total volume of 40 ml. The other forty-eight patients received 35 ml bupivacaine 0.25% + 250 mg of magnesium sulfate with a total volume of 40 ml. Results: Total postoperative pethidine consumption in the first 24 h post-operative showed a highly statistically significant decrease in the magnesium group in comparison to the bupivacaine group. Conclusion: Adding magnesium sulfate to bupivacaine in FICB in skin grafting procedures decreased the pain scores post-operative, delayed the first request of analgesia and reduced the total analgesic consumption in the first 24 h post-operative without any significant side effects.
