Experience of labor induction | Dinoprostone pessary N = 614 | Dinoprostone gel N = 190 | Misoprostol tablet N = 55 | Intracervical balloon N = 40 | ||||
|---|---|---|---|---|---|---|---|---|
n (%) | aRR (95% CI) a | n (%) | aRR (95% CI) a | n (%) | aRR (95% CI) a | n (%) | aRR (95% CI) a | |
Labor went quite normally | 370 (61.0) | 1.00 (Reference) | 117 (62.9) | 1.02 (0.87, 1.18) | 35 (63.6) | 1.04 (0.87, 1.24) | 28 (71.8) | 1.03 (0.81, 1.31) |
Labor proceeded just about as expected | 261 (42.8) | 1.00 (Reference) | 87 (46.8) | 1.31 (0.84, 1.37) | 27 (49.1) | 1.14 (0.91, 1.44) | 22 (55.0) | 1.25 (0.86, 1.83) |
Length of labor was acceptable | 359 (59.1) | 1.00 (Reference) | 102 (55.7) | 0.93 (0.78, 1.10) | 36 (65.5) | 1.09 (0.93, 1.28) | 26 (65.0) | 1.07 (0.77, 1.49) |
Delivery proceeded exactly as expected | 265 (43.7) | 1.00 (Reference) | 90 (48.4) | 1.07 (0.88, 1.29) | 26 (47.3) | 1.03 (0.78, 1.35) | 26 (65.0) | 1.38 (1.00, 1.35) |
Absence of vaginal discomfort during the induction | 297 (49.0) | 1.00 (Reference) | 92 (49.2) | 0.97 (0.82, 1.13) | 37 (67.3) | 1.34 (1.20, 1.48) | 18 (47.4) | 1.23 (0.89, 1.70) |
Maximum pain perceived, numeric scale < 8/10 | 170 (32.3) | 1.00 (Reference) | 57 (34.6) | 1.03 (0.82, 1.29) | 19 (35.9) | 1.31 (0.96, 1.80) | 21 (56.8) | 1.78 (1.20, 2.65) |
Globally satisfied about the induction | 425 (69.7) | 1.00 (Reference) | 130 (70.7) | 1.00 (0.90, 1.12) | 37 (67.3) | 0.98 (0.87, 1.10) | 27 (67.5) | 0.87 (0.70, 1.08) |
If labor had to be induced again, the same method would be liked | 398 (65.9) | 1.00 (Reference) | 139 (75.5) | 1.11 (0.98; 1.26) | 42 (77.8) | 1.18 (0.96; 1.46) | 27 (67.5) | 0.90 (0.70; 1.16) |
