AbstractShort communicationThis study aimed to investigate the role of prolonged second stage of labour and second stage caesarean section on the risk of spontaneous preterm birth (sPTB) in a subsequent pregnancy.Objectives and MethodsThis was a retrospective cohort study of nulliparous women with two consecutive singleton deliveries between 2014 and 2017 at a tertiary centre. In the vaginal delivery cohort, subsequent pregnancy outcomes for women with a prolonged second stage (>2 h) were compared with those with a normal second stage (≤2 h). In the caesarean delivery cohort, women with a first stage or a second stage were compared with the vaginal delivery cohort. The primary outcome was subsequent sPTB.ResultsA total of 821 women met inclusion criteria, of which 74.8% (614/821) delivered vaginally and 25.2% (207/821) delivered by caesarean section. There was no association between a prolonged second stage in the index pregnancy and subsequent sPTB (aOR 0.70, 95% CI 0.13–3.83, p=0.7). The risk of subsequent sPTB was threefold for those with a second stage caesarean section; however this did not reach statistical significance.ConclusionsA prolonged second stage of labour in the index pregnancy is not associated with an increased risk of subsequent sPTB. A second stage caesarean section in the index pregnancy may be associated with an increased risk of subsequent sPTB, however there was no statistically significant difference. These findings are important for counseling and suggest that the effects of these factors are not clinically significant to justify additional interventions in the subsequent pregnancy.

Abstract Background Full dilatation caesarean sections are associated with recurrent early spontaneous preterm birth and late miscarriage. The risk following first stage caesarean sections, are less well defined, but appears to be increased in late-first stage of labour. The mechanism for this increased risk of late miscarriage and early spontaneous preterm birth in these women is unknown and there are uncertainties with regards to clinical management. Current predictive models of preterm birth (based on transvaginal ultrasound and quantitative fetal fibronectin) have not been validated in these women and it is unknown whether the threshold to define a short cervix (≤25 mm) is reliable in predicting the risk of preterm birth. In addition the efficacy of standard treatments or whether benefit may be derived from prophylactic interventions such as a cervical cerclage is unknown. Methods There are three distinct components to the CRAFT project (CRAFT-OBS, CRAFT-RCT and CRAFT-IMG). CRAFT-OBS: Observational Study; To evaluate subsequent pregnancy risk of preterm birth in women with a prior caesarean section in established labour. This prospective study of cervical length and quantitative fetal fibronectin data will establish a predictive model of preterm birth. CRAFT-RCT: Randomised controlled trial arm; To assess treatment for short cervix in women at high risk of preterm birth following a fully dilated caesarean section. CRAFT-IMG: Imaging sub-study; To evaluate the use of MRI and transvaginal ultrasound imaging of micro and macrostructural cervical features which may predispose to preterm birth in women with a previous fully dilated caesarean section, such as scar position and niche. Discussion The CRAFT project will quantify the risk of preterm birth or late miscarriage in women with previous in-labour caesarean section, define the best management and shed light on pathological mechanisms so as to improve the care we offer to women and their babies. Trial registration CRAFT was prospectively registered on 25th November 2019 with the ISRCTN registry (10.1186/ISRCTN15068651).

Background: Adverse maternal and perinatal outcomes are related to pregnancies spaced too closely together. Objective of present study was to compare the expulsion rate and complications between post placental IUCD insertion between caesarean section and vaginal delivery.Methods: This study was a prospective comparative study conducted in the department of Obstetrics and Gynecology, at Agartala Government Medical College over 1.5 Years (January 2016-June2017) All cases at term pregnancy delivering by caesarean section and vaginal delivery were divided into two different groups. Sample size of 105 in each group. Subjects recruited from-obstetrics OPD and casualty of Agartala Government Medical College (AGMC) and GB Pant Hospital expulsion rate and complications. Comparative evaluation of Expulsion rate and complications following post placental IUCD insertion between caesarean section and vaginal delivery at the end of six months, one year and one and half year.Results: There was no significant difference in either complications between the two groups (P value-.913) or outcomes (p value-.035). Expulsion rate 18.2% following vaginal delivery compared to those with intracaesarean insertion i.e 3.8%.Conclusions: The complications associated with postplacental Intrauterine device insertion is insignificant, still the awareness, acceptance and continuation are very low. Therefore Information, education Communication activity by the field workers must be enhanced to overcome this knowledge gap.
