“…CDB is a good alternative method for inducing women with unfavorable cervix [14] ,which has been a commonly used induction for the term pregnancies [15] , prolonged pregnancies [16] , vaginal birth after caesarean section [17] , high risk of uterine hyperstimulation [18] , and oligohydramnios [19] . CDB used in labor has low risk of hyperstimulation and brings high maternal satisfaction [20] .…”

Background Pregnancy termination in the second trimester is a complex and delicate situation for patients with complete placenta previa (CPP), which has less been reported. The objective of this research was to investigate and evaluate the clinical effect of uterine artery embolization(UAE) combined with cervical double balloon(CDB) for patients with CPP. Methods We conducted a retrospective study based on a large medical center. The medical records of patients who were diagnosed with CPP and treated UAE combined with CDB for termination in the second trimester in our hospital from January 2017 and March 2021 were retrospectively reviewed. The clinical outcomes were analyzed.Results A total of 11 patients with CPP were included in this study. Prenatal diagnosis of CPP was realized by trans-vaginal ultrasound. The average age was 34.2 years old, and the gestational week was 21.6 weeks. Of the selected patients, 3 cases (3/11) had previous caesarean delivery, 5 cases were at older maternal age (≥35 years old), 10 cases underwent emergency UAE for prenatal bleeding equal or up to 400 mL and 1 case underwent prophylactic UAE for placenta percreta, and all cases underwent CDB to promote cervical ripening. It was worth noting that 5 cases (5/11) of selected patients underwent curettage to take out fetus and placenta. The uterus preservation was achieved in all 11 patients. The complications associated with conservative management included prenatal hemorrhaging (10/11), blood transfusion (5/11), fever (2/11), and septicemia (1/11). The mean dilation of cervix was from 0cm to 1.9cm, the length of cervix was from 3.5cm to 0.6cm and the Bishop scores were from 1.5 to 7.3 after using CDB, the changes of cervical conditions were statistically significant (p＜0.05). The levels of WBC and CRP were higher after termination with medicine+UAE+CDB and/or curettage. Conclusion The adjuvant therapy of UAE, CDB, and/curettage step by step is a preferred choice for patients with CPP who underwent pregnancy termination in the second trimester.

“…This prospective descriptive-analytical study was the first part of a larger research project titled "A nomogram for cesarean risk assessment and evaluating the effect of cervical ripening balloon and evening primrose oil comparing with misoprostol on Bishop Score and duration of first stage of labor" that was approved by Tabriz University of Medical Sciences (ethical code IR.TBZMED.REC.1399.141) and a protocol has been published (Hemmatzadeh et al, 2021). This section aimed to develop and validate a predictive model of cesarean section after labor induction with an unfavorable cervix, which was done in the labor and delivery units of three selected academic and non-academic hospitals from September 2020 to June 2021.…”

This study aimed to develop and validate a labor induction nomogram for nulliparous and multiparous women who were 38 weeks pregnant or more and had their labor induced by an unfavorable cervix. This prospective study was conducted on 300 individuals (200 for nomogram development and 100 for nomogram validation). Height, body mass index at delivery, parity, gestational age, adjusted bishop score, and cesarean section risk assessment were all recorded on a checklist. Participants were followed until they gave birth, and the type of delivery was noted in the checklist. Out of 300 labor inductions, 80 (26.7%) underwent a cesarean section. Cesarean risk estimation was the only predictor of delivery type based on multivariate logistic regression. The AUC (Area Under the Curve) in development group was 0.68 and in validation group was 0.71. The developed nomogram for predicting of cesarean section risk following labor induction has a relatively good predictive value among women.
