Evaluation of the Level of Oxidative Stress in Relation to the Type of Anesthesia in Parturients Whose Delivery Was Completed by Caesarean Section

The goal of this observational study is to assess the level of oxidative stress during cesarean section depending on the type of anesthesia applied and to determine the factors that can affect the level of oxidative stress.

The main questions it aims to answer are:

* is there any association between specific parameters of pregnancy, socio-demographic characteristics and laboratory analyses with an increased level of oxidative stress * is there any association between type of anesthesia for ceasarean section with an increased level of oxidative stress

Blood sample would be taken from the participants in the study for these analyses on three occasions in 3 test tubes (before cesarean section, during cesarean section and after cesarean section).

Researchers will compare patients that received general anesthesia with patients under spinal regional anesthesia to see if there is any difference in level of oxidative stress measured by laboratory parameters.
