Background: Magnesium sulphate (MgSO4 ) infusion started before surgery in spinal anesthesia reduces the analgesic requirement and shivering. In this study, it was aimed to investigate the effects of magnesium sulphate infusion during spinal anesthesia and postoperative first 24 hours on block time, sedation and postoperative analgesic consumption.
Methods: 10 mg / kg bolus and 500 mg / hour magnesium sulphate and serum were administered to Group M for 24 hours. Group R received only Ringer Lactate i.v infusion. Group R and Group M received 10 mlt / kg Ringer’s lactate for intraoperative. In the first 24 hours: shivering, the first pain sensation, motor block withdrawal period and analgesic requirement of the groups were evaluated, as well as a 6-hour sedative and visual analog scores.
Results: A significant decrease in total analgesic consumption was detected in the magnesium infusion group for 6-hour (Tenoxicam: Group M: 50 ± 20 mg, Group R: 80 ± 20 mg for 24 hours, p: 0.001). At the same time, visual analogue scores decreased over all periods. There was no difference between motor block regression and sedation scores.
Conclusion: It was concluded that magnesium sulfate infusion was a safe drug to reduce analgesic consumption for spinal blockade and to reduce shivering without affecting daily activities.
