Primary End Point
Baseline pain scores reported just before neuraxial analgesia
were similar between groups, but time to complete
analgesia was shorter in the CSE group (Table 3). Patients
in the CSE group reported better analgesia during the first
stage of labor based on a lower typical VRPS score (1.4 vs
1.9; P < 0.001; 99.5% CI of difference: −0.92, −0.14). Pain
scores during the second stage of labor (1.7 vs 1.9; P = 0.17;
99.5% CI of difference: −0.82, 0.28) and at delivery (2.0 vs
2.0; P = 0.77; 99.5% CI of difference: −0.73, 0.59) were not
different between groups. Scheduled hourly pain scores
were similar between groups with the exception of first
hour in which better analgesia was observed in the CSE
group (Table 4
