Effects of IV Magnesium Sulphate on Hemodynamic Response To Pneumoperitoneum In Laparoscopic Cholecyctectomy; A Randomized Control Trial

Abstract

Objective: To determine the effect of IV Magnesium sulphate (MgSO4) in attenuating the hemodynamic effects of pneumoperitoneum.
 Methodology: Our single blind randomized control trial (based on computer generated randomize allocation) was carried out at Holy Family Hospital and included 60 patients, not allergic to MgSO4 and belonging to the American Society of Anesthesiology (class 1 and 2. Patients were divided into two groups with Intervention group (M group) receiving 30 mg/kg of MgSO4 and the control group (C group) receiving a placebo. Hemodynamic parameters were then measured at different points of time during surgery. Data was collected and analyzed by using statistical package for the social sciences (SPSS) version 25.0.
 Results: Out of 60 patients selected 86.7% were females while 13.3% were males. Mean age was 35.78(SD=8.26). As compared to group, patients belonging to group had significantly lower heart rate, systolic and diastolic blood pressure at 15 minutes, after release of pneumoperitoneum and at extubation with p values less than 0.05.
 Conclusion: Our study concludes that 30 mg/kg of MgSO4 given as a bolus just before creation of pneumoperitoneum protect against its possible adverse hemodynamic effects.
