Term pregnancy labour induction of nulliparous women with gestational hypertension, diabetes

Labour induction (LI) is associated with better maternal, perinatal outcome and should be offered to patients with gestational hypertension (GH) from 37+0, gestational diabetes (GD) after a full 38weeks of gestation. Data were collected retrospectively in year 2019. 163 Riga Maternity hospital inducted labour medical hystories of singleton, cephalic, nulliparous women ≥37+0 weeks of gestation with GD, GH were reviewed. Data were analyzed with SPSS 26.0. Women’s mean age was 29 years±5.0 with mean BMI 24.4±4.9kg/m2. Data were divided into two groups – first included 67 (41.1%) patients from ≥ 37+0 to 40+0 weeks of gestation, second – 96 (58.9%) from 40+1weeks of gestation. As a maternal comorbidity, GD and preeclampsia were more common in group 1 – 18 (26.9%), 29 (43.3%); GD and GH were more common in group 2 – 34 (35.4%), 33 (34.4%), p=0.045. Mean duration from LI to 1st stage in groups were 14h59min±11h24min and 16h6min±12h6min, p=0.213; of the 1st stage – 6h47min±3h14min and 8h12min±3h20min, p=0.238; 2nd stage – 56min±39min and 1h8min±49min, p=0.405, accordingly. In groups 29 (43.3%) and 49 (51.0%) were vaginal births, 29 (43.3%) and 35 (36.5%) labours were completed by caesarean section, p=0.713. Apgar scores for groups were 7.58±0.59 and 7.53±0.72 at 1 minute, p=0.402, 8.72±0.50 and 8.72±0.51 at 5 minute, p=0.609, respectively. 10 (14.9%) newborns of group 1 and 13 (13.5%) of group 2 entered the neonatal intensive care unit, p=0.803; 4 (6.0%) and 13 (13.5%) were injured during labour, p=0.120. 20 (29.9%) group 1 and 33 (34.4%) group 2 mothers did not have vaginal births within 24h after LI, p=0.544. LI did not affect perinatal or maternal outcome in this study. To determine statistically significant differences between the groups, they should be extended.
