Key result
Prolonged spinal anesthesia-to-delivery interval, driven by factors like higher BMI and placenta previa, was significantly inversely correlated with umbilical arterial pH (r = -0.163, P = .001).
Why the study?
Longer intervals from spinal anesthesia to cesarean delivery are associated with lower umbilical arterial pH levels, prompting the need to identify specific risk factors related to this interval.
What factors influence the spinal anesthesia-to-delivery interval in elective cesarean sections, and how does this interval affect umbilical arterial pH?

May warrant minimizing spinal-to-delivery intervals when feasible; leaves open whether shortening improves neonatal outcomes.

What factors influence the spinal anesthesia-to-delivery interval in elective cesarean sections, and how does this interval affect umbilical arterial pH?
Effect estimate: r = -0.163
p-value: p=.001
In elective cesarean sections, specific maternal and obstetric factors prolong the spinal anesthesia-to-delivery interval, which is associated with a slight but significant decrease in umbilical arterial pH.
Kinoshita et al. (2025) conducted an observational in Elective cesarean sections (n=404). Prolonged spinal anesthesia-to-delivery interval was evaluated on Umbilical arterial pH levels (r = -0.163, p=.001). Prolonged spinal anesthesia-to-delivery interval, driven by factors like higher BMI and placenta previa, was significantly inversely correlated with umbilical arterial pH (r = -0.163, P = .001).
