Effect of intraoperative Magnesium sulphate on Electro-Encephalogram in patients undergoing lumbar fixation

Aim:This study aimed to assess theElectro-Encephalogram changes after intraoperative Magnesium sulphate in patients undergoing lumbar fixation. Methods: This study was conducted at Beni-Suef University Hospital on 80 patients indicated for lumbar fixation. The selected patients were randomly assigned to one of the following two groups; the first group will received conventional general anesthesia only (40 participants) (control group), and the second group will received conventional general anesthesia with extra administration of intraoperative magnesium sulphate (40 participants) (Mg sulphate group). Result: The mean age of patients in Mg sulphate group was 46.11±11.89 years and most of them were males (67.5%) with average BMI 29.21±3.54.There was a significant difference between in postoperative period between Mg sulphate group and controlgroup without in the occipital (1,2) and temporal regions as regard absolute power of theta and alpha rhythms. Conclusion: This study concluded that there was a significant effect of Mg sulphate on the EEG in the form of increased absolute power of theta and alpha rhythms in the occipital (1,2) and temporal regions.
