Dr. M Rajasekhar | Dr. Farooq Basha | Dr. Sudheer Kumar
Abstract: Introduction: Cesarean sections are performed mostly under spinal anesthesia. Shivering is one of the distressing complications. Some patients find shivering sensation worse than the surgical pain. Therefore, both prevention and treatment of established shivering should be regarded as clinically relevant intervention in the perioperative period. Aim and Objectives: The aim of the study was to compare the efficacy of magnesium sulfate when used for prevention or treatment of shivering following spinal anesthesia in elective cesearean section. Material and Methods: A prospective, comparative study was done in 80 pregnant women aged between 18 and 35 years age, undergoing elective cesarean section under spinal anesthesia. Patients were categorized into 2 groups-Group P and Group T. Following intrathecal injection, Group P (prophylactic) was given MgSO4, 50 mg/kg I.V. bolus + 2 mg/kg/h infusion. Group T (therapeutic) was given MgSO4 50 mg/kg I.V. bolus as a therapy when shivering occurred. If shivering persisted, they received 25 mg/kg I.V. bolus. Shivering grade 3/4 was regarded as significant, incidence of shivering, and side effects were recorded. Results: The incidence of shivering was 40% in Group P, 60% in Group T. Total incidence of shivering was significantly low in Group P when compared to Group T. Hypotension was more frequent in Group P; nausea and vomiting were more in Group T. Conclusion: Magnesium sulfate significantly reduced the incidence of shivering when used as prophylaxis in pregnant women undergoing cesarean section under spinal anesthesia. Magnesium sulfate reduces the severity of the shivering.
