Cesarean Anesthesia Blood Gas
Effects of Spinal and General Anesthesia Techniques on Maternal-Fetal Blood Gas Gradients and Fetal Carboxyhemoglobin Levels in Cesarean Delivery: A Prospective Observational Cohort Study
This prospective observational cohort study will evaluate maternal and fetal blood gas parameters in women undergoing cesarean delivery under spinal or general anesthesia. Maternal venous blood samples will be obtained immediately before anesthesia induction, and umbilical arterial blood samples will be obtained after delivery and cord clamping. Blood gas parameters, including pH, pCO2, pO2, bicarbonate, base excess, lactate, and fetal carboxyhemoglobin levels, will be compared between the spinal and general anesthesia groups. The study will also evaluate maternal-fetal blood gas gradients, Apgar scores, neonatal intensive care requirements, and the relationship between smoking exposure and fetal carboxyhemoglobin levels.

調査対象母集団
Pregnant women undergoing cesarean delivery at the Obstetrics and Gynecology Clinic of Bagcilar Training and Research Hospital. The study is a prospective observational cohort comparing maternal and fetal blood gas parameters and fetal carboxyhemoglobin levels according to the observed anesthesia technique (spinal or general anesthesia).
説明
Inclusion Criteria:
- Adult women undergoing cesarean delivery at the study center.
- Patients receiving spinal or general anesthesia for cesarean delivery.
Exclusion Criteria:
- Patients who are not eligible for participation according to the study protocol.
- Patients in whom spinal anesthesia is converted to general anesthesia because of inadequate spinal block and pain during surgery.
