Cesarean Anesthesia Blood Gas

Condition(s) studied

Investigational drug(s) / intervention(s)

Anesthesia Technique: Observed anesthesia technique in women undergoing cesarean delivery. Participants received either spinal anesthesia or general anesthesia as part of routine clinical care; the anesthesia technique was not assigned by the study.

Study summary

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.

Eligibility

Primary outcome measure(s)

• Umbilical artery pH — Immediately after delivery
  Umbilical arterial pH measured after delivery and cord clamping.
