Clinical Trial Summary

Magnesium therapy used for seizure prophylaxis in patients with preeclampsia. Magnesium has been shown to prolong the effect of nondepolarizing neuromuscular blocking agents (NMBA) and neostigmine used to reverse the effect of NMBA in general anesthesia . In this study, the investigators aimed to evaluate time from sugammadex injection to Train-of-four ratio 0.9 who receieved magnesium therapy in reversing the effect of neuromuscular blocking agent during the recovery period and the relationship between magnesium level and duration of action of sugammadex


Description:

Rapid-onset and short-acting agents should be preferred in induction, and full induction doses should be applied since they do not receive premedication and increased volume of distribution. Rapid serial induction and intubation should be performed in pregnancies greater than 20 weeks due to the risk of aspiration. Magnesium potentiates and prolongs the effect of nondepolarizing neuromuscular blocking agents. It is recommended that the TOF value be between 0 and 2 for adequate muscle relaxation in cesarean section anesthesia. In anesthesia induction; thiopental 3-6mg/kg, rocuronium 1mg/kg, and fentanyl 1mcg/kg and dormicum 2mg will administered after the baby birth. Sevoflurane 2-3% and 50% oxygen + 50% air are used for maintenance. If TOF is 0, sugammadex 4mg/kg will be administered to reverse the effect of the muscle relaxant.A blood sample will be taken to measure simultaneous calcium and magnesium values. Patients with a TOF ≥0.9 (gold standard for extubation) or patients will be clinically evaluated and the decision to extubate will be made.

Study Design


Intervention

Drug:
pregnant women taking magnesium
The patient group who received magnesium as a 4-6 g loading and 2-3 g/h maintenance dose to prevent convulsions in preeclampsia. Pregnant will be operated under general anesthesia. Sugammadex 4mg/kg will be administered when TOF 0 response is seen at the end of surgery. The time from TOF 0 to TOF 0.9 will be recorded. Magnesium and calcium levels in the blood will be studied.
Placebo
Pregnant women who do not receive magnesium therapy and who will be operated under general anesthesia. Sugammadex 4mg/kg will be administered when TOF 0 response is seen at the end of surgery. The time from TOF 0 to TOF 0.9 will be recorded. Magnesium and calcium levels in the blood will be studied.
