Key result
Cesarean section under general anesthesia increased maternal beta-endorphin levels more than epidural anesthesia (34.4 vs 15.5 pmol/L, P<0.02), indicating greater maternal stress.
Why the study?
Does the mode of delivery and anesthesia affect beta-endorphin levels in maternal and umbilical cord plasma in healthy women at term pregnancy?
Population
30 healthy women at term pregnancy

Should not yet change anesthesia selection in cesarean; leaves open whether beta-endorphin differences affect clinical outcomes.

Does the mode of delivery and anesthesia affect beta-endorphin levels in maternal and umbilical cord plasma in healthy women at term pregnancy?
p-value: p=<0.02
Cesarean section under general anesthesia is associated with a greater maternal stress response (measured by beta-endorphin release) compared to epidural anesthesia, while spontaneous labor results in the highest beta-endorphin levels in both maternal and fetoplacental circulation.
Räisänen et al. (1987) conducted an observational in healthy women at term pregnancy (n=30). Cesarean section under general anesthesia vs. Cesarean section under epidural anesthesia and spontaneous labor was evaluated on Maternal and umbilical cord plasma beta-endorphin concentration (p=<0.02). Cesarean section under general anesthesia increased maternal beta-endorphin levels more than epidural anesthesia (34.4 vs 15.5 pmol/L, P<0.02), indicating greater maternal stress.
