Clinical Report: Effects of Timing of Scheduled Cesarean Deliveries

Overview

This study evaluates maternal and neonatal outcomes of scheduled cesarean sections performed on working versus non-working days. No significant differences in short-term outcomes were found between the two groups.

Background

Cesarean sections are essential for managing high-risk pregnancies. Previous studies have suggested that the timing of cesarean deliveries may influence outcomes, particularly the so-called 'weekend effect.' However, high-quality evidence specifically addressing scheduled cesarean sections is limited.

Data Highlights

OutcomeWorking DaysNon-Working Days
Postoperative FeverNo significant differenceNo significant difference
Neonatal TransferNo significant differenceNo significant difference
Surgical Blood LossNo significant differenceNo significant difference
Postoperative Hospital StayNo significant differenceNo significant difference
Antibiotic DurationNo significant differenceNo significant difference
Umbilical Cord pHNo significant differenceNo significant difference
Operative DurationLongerShorter (β = −3.82, p = 0.029)

Key Findings

  • No significant differences in postoperative fever, neonatal transfer, surgical blood loss, postoperative hospital stay, or antibiotic duration between working and non-working days.
  • Umbilical cord blood gas parameters showed no significant differences between the two groups.
  • Surgery on non-working days was associated with a shorter operative duration.
  • Propensity score matching effectively balanced confounding factors in the analysis.
  • Study conducted in a single-center setting with standardized staffing configurations.

Clinical Implications

The findings indicate that the timing of scheduled cesarean sections does not significantly impact short-term maternal and neonatal outcomes.

Conclusion

This study indicates that scheduled cesarean sections can be performed on both working and non-working days without significant differences in short-term outcomes.
