Influence of maternal obesity on Bishop Score and failed induction of labour: A retrospective cohort study in a regional tertiary centre

Abstract

Maternal obesity is associated with a lower BS, more difficult IOL process, and increased risk of failed IOL and CS.

Predicting factors of failed induction of labor in three hospitals of Southwest Ethiopia: a cross-sectional study

“…Women whose body mass index > 24 kg/m 2 were 5.7 times more likely to had failed induction as compared with women whose body mass index ≤24 kg/m 2 . This finding is supported by previous findings [ 38 , 39 , 41 – 43 ]. This could be due to; maternal obesity is related with a lower bishop score, women with lower bishop scores are at greater risk for failed induction [ 41 ].…”

“…This finding is supported by previous findings [ 38 , 39 , 41 – 43 ]. This could be due to; maternal obesity is related with a lower bishop score, women with lower bishop scores are at greater risk for failed induction [ 41 ]. In addition, to achieve vaginal delivery, obese women require more concentration, higher doses, and longer duration of exposure of uterotonics medication, using similar protocol and guidelines on labor induction for all women with different BMI to end up with higher failure rate among obese women [ 44 , 45 ].…”

“…Primiparous women were 2.3 times more likely to had failed induction than multipara women. This study is similar to the previous studies; nulliparous women are at greater risk for both failed inductions and cesarean sections as compared to multiparous women [ 12 , 16 , 20 , 35 , 38 , 40 , 41 ]. This might be due to the higher proportion of unfavorable bishop scores in Primiparous in the study; it may also be the reason that the lack of important practices likes the use of misoprostol with oxytocin to induction in Primiparous.…”

“…This finding is supported by studies in which the earlier epidural analgesia was given during labor, the higher the probability of cesarean delivery among induced women [ 7 , 13 , 18 ]. This might be using epidural anesthesia during induction of labor was related to a low bishop score which increased the rate of failed induction [ 41 ].…”

“…Women whose newborn birth weight ≥ 4000 g were 2 times more likely to have failed induction as compared with women whose newborn birth weight was 2500–3900 g. This study is supported by the previous studies [ 16 , 39 ]. This might happened due to the mean birth weight of neonates were higher among women who had greater BMI [ 44 ], larger BMI leads to lower bishop scores, and failed induction of labor [ 41 ].…”
