To Compare the Effects of Oxytocin and Carbetocin on Intraoperative Hemodynamic Changes in Cesarean Section Surgeries.

The study will have a double-blind design and will be conducted after obtaining an approval from the local ethics committee. The study will include 80 patients planned for elective caesarean section surgeries , aged 18-40 years with an ASA score of I-II. The patients will be randomized by sealed tender and will be divided into 2 groups with 40 patients each.

All cases will receive routine preparation for general anesthesia. All patients placed on the operating room will receive two large-bore vascular access. For anesthesia induction 2 mg/kg propofol and 0.5 mg/kg rocuronium will be used. Anesthesia will be maintained with 60% air, 40% oxygen and 2 MAC sevoflurane.Demographic data of the patients (age, height, weight), ASA score and surgical time will be recorded. During the operation, hemodynamic parameters will be recorded just before the drugs are given and at the 1st, 5th, 10th, 15th, 20th, 25th and 30th minutes after the drug is given. In addition, intraoperative blood loss and the need for additional uterotonics throughout the surgery will be recorded. All data will be recorded and statistical analysis will be made.
