In this study, investigators aimed to investigate the effects of general and spinal anesthesia techniques on copeptin levels during cesarean section and their relation with fetal distress.

During the delivery process, the mother and the baby generate some endocrine responses to this emotional and physical stressful action. Arginin-Vasopressin prohormone (copeptin), which is more stable and measurable in blood, is used as an endogenous stress indicator. Copeptin levels have been shown to be significantly increased in vaginally delivery when compared to cesarean section (c / s). In a caesarean section; it is a known fact that when the general anesthetic method and the used anesthetic substances are taken into consideration, it gives a significant stress to the mother and the baby. Spinal anesthesia with no impaired fetal oxygenation and without orotracheal intubation and neuromuscular blockers may reduce fetal distress. However, there was no study investigating the effect of the anesthesia techniques in elective cesarean section on the fetal stress and the level of copeptin, in the literature review. Therefore investigators aimed to compare spinal and general anesthesia technique in elective cesarean section, to evaluate level of copeptin and their relation with fetal distress.Investigators hope that this study will guide the anesthesia method that can be chosen primarily in caesarean section.
