5. Study Description

Brief 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
Detailed 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.

Interventional Study Model
Parallel Assignment
Model Description
A total of 30 pregnant women, who are taking magnesium and not taking magnesium, will be included in the study to be taken by cesarean section under general anesthesia.At the end of surgery, whether sugammadex reverses the effect of NMBA will be evaluated. The time up to TOF 0.9 will be recorded.A blood sample will be taken to measure simultaneous calcium and magnesium values.
Masking

Masking Description
It will be evaluated by another investigator (blind) who does not know in which group the patient is using magnesium sulfate during the intraoperative period.
