Magnesium therapy in pre-eclampsia prolongs analgesia following spinal anaesthesia with fentanyl and bupivacaine: An observational study.

İstanbul Bilim Üniversitesi, Tıp Fakültesi.BACKGROUND: Magnesium has anti-nociceptive effects and potentiates opioid analgesia following its systemic and neuraxial administration. However, there is no study evaluating the effects of intravenous (IV) magnesium sulphate (MgSO4) therapy on spinal anaesthesia characteristics in severely pre-eclamptic patients. AIMS: The aim of this study was to compare spinal anaesthesia characteristics in severely pre-eclamptic parturients treated with MgSO4 and healthy preterm parturients undergoing caesarean section. Thus, our primary outcome was regarded as the time to first analgesic request followingspinal anaesthesia
