Magnesium sulfate as an adjuvant in postoperative analgesia in patients undergoing maxillofacial procedures

Abstract

Introduction: In maxillofacial surgery, postoperative pain is a common problem in patients. Magnesium Sulfate is known for its analgesic power due to its effects as a calcium channel blocker and N-methyl-D-aspartate receptor antagonist. which plays an important role in the development of pain. Objective: To evaluate the analgesic effect of intravenous magnesium sulfate in patients undergoing maxillofacial procedures under intravenous sedation in the dental service of the outpatient headquarters of the La Trinidad Medical Teaching Center. Materials and Methods: Experimental study: clinical trial type, (double blind). Sample: 40 patients randomly divided into two groups of 20 patients each, group #1 was made up of patients who received magnesium sulfate at a dose of 30 mg/kg plus the usual premedication, group #2 was made up of patients who only received the premedication established in the protocol plus infusion of 09% NaCl solution. Results: When comparing the measurement of postoperative pain using the VAS, postoperative pain control was evident in both groups, however the greatest number of cases that reported VAS with absence of pain and little pain was observed in the group treated with magnesium sulfate. Conclusions: The administration of intravenous magnesium sulfate at a dose of 30 mg/kg reduces the intensity of postoperative pain compared to the control group in patients undergoing maxillofacial procedures under intravenous sedation in the dental service of the outpatient headquarters of the La Trinidad Medical Teaching Center.
