Brief summary

In the preoperative period, 60-80% of the patients had anxiety symptoms. This rate increases even more during pregnancy. There are a number of studies examining the role of anxiety symptoms on fetal outcome, but the mechanisms that explain the effects of maternal stress are not fully understood. The most extensively studied cytokines in neuropsychiatric disorders are TNF-α and IL-6 due to their effects on the central nervous system. TNF-α levels have been reported to be elevated in anxiety disorders. In our study, the investigators aimed to determine the relationship between preoperative anxiety levels and fetal cord blood TNF-α and IL-6 cytokine levels in pregnant women.

Detailed description

This prospective observational study is planned to involve 30 volunteer patients between 18-40 years of age who will undergo elective caesarean section surgery. People with known psychiatric illness and medication use, illiterate, who do not have mental competence to understand survey questions and very urgent patients will not be included in the study. Preoperative anxiety levels will be determined by the STAI-Continuity scale at the time of admission to the anesthesia outpatient clinic and by the STAI-State scale 1 hour before surgery.The scales will be scored as normal, mild, moderate and severe anxiety. Psychiatric consultation will be requested for patients with severe anxiety. At the end of the cesarean section, the concentration of TNF-α and IL-6 cytokines in the blood remaining from routine blood gas taken from the umbilical cord will be determined to obtain information about the state of fetal well-being.

Interventions

OTHERPreoperative anxiety levels

Serums were separated from blood samples taken from all patients in the study, Using the anti-human TNF-α and IL-6 enzyme-linked immunosorbent assay (ELISA) kits in the Elisa device, the TNF-α and IL-6 cytokines will be measured to determine their concentration. No routine blood will be drawn during the procedures. Preoperative anxiety levels will be evaluated with STAI-Continuity and STAI-Statefulness scale.
