A Single-center Retrospective Cohort Study on Cesarean Section under General Anesthesia

Area of Science:

• Anesthesiology
• Obstetrics
• Neonatal Care

Background:

• Neuraxial block is standard for cesarean section (CS).
• General anesthesia (GA) is crucial for urgent/high-risk CS.
• Understanding GA indications and outcomes in CS is vital.

Purpose of the Study:

• To identify reasons for using GA in CS.
• To analyze factors influencing maternal and fetal outcomes under GA for CS.
• To assess the relationship between maternal health status, gestation, and outcomes.

Main Methods:

• Retrospective analysis of 98 CS cases under GA (2014-2016).
• Collected clinical data on maternal status, perioperative information, and outcomes.
• Compared ICU admission rates, hospital stay, and neonatal Apgar scores based on ASA grade, gestational age, and blood loss.

Main Results:

• Internal/surgical diseases (60.2%) were the primary reason for GA in CS.
• Higher ASA grade (III-IV), preterm gestation (<37 weeks), and significant blood loss (>800ml) correlated with higher ICU rates.
• Preterm gestation and higher ASA grade were associated with longer hospital stays and lower neonatal Apgar scores.

Conclusions:

• Maternal medical conditions are the main drivers for GA in CS.
• High maternal ASA grade and preterm gestation are risk factors for adverse maternal and neonatal outcomes following GA for CS.
