OBJECTIVES: This study aimed to compare plasma concentrations of anesthetic drugs administered during Cesarean section with low Apgar score in neonates deliveried under general anesthesia and analyze associated risk factors.
METHODS: Data from 76 neonates undergoing Cesarean section under general anesthesia with blood concentrations of anesthetic drugs were analyzed. A low Apgar score was defined as ≤ 7. Perioperative maternal and neonatal data were collected and analyzed. Neonates were divided into a control group (Group CON, n = 65) and a low Apgar score group (Group LAS, n = 11) based on Apgar score.
RESULTS: There were no significant differences in the plasma concentrations of anesthetic drugs in maternal artery, umbilical vein or umbilical artery blood between the two groups. Risk factors for neonatal low Apgar scores during Cesarean section under general anesthesia were premature delivery (aOR 10.2, 95% CI = 1.8-56.9) and preoperative fetal distress (aOR 9.6, 95% CI = 1.3-69.0). The prediction model was: probability = 1/(e‑Y), Y= -4.607 + 2.318× (premature delivery) + 2.261× (fetal distress) (yes = 1, no = 0). The Hosmer-Lemeshow test showed χ²= 9.587, P = 0.213, and the area under the curve (AUC) was 0.850 (0.670 ~ 1.000). With a cutoff value of 0.695, sensitivity and specificity were 81.8% and 87.7%, respectively.
CONCLUSIONS: There was no correlation between blood concentration of general anesthetic drugs and Apgar score or occurrence of neonatal low Apgar scores. Premature delivery and preoperative fetal distress were identified as independent risk factors for neonatal low Apgar scores after Cesarean section under general anesthesia.
