Risk factors for labour induction and augmentation: a multicentre prospective cohort study in India.

Background: Guidelines for labour induction/augmentation involve evaluating maternal and fetal complications, and allowing informed decisions from pregnant women. This study aimed to comprehensively explore clinical and non-clinical factors influencing labour induction and augmentation in an Indian population. Methods: A prospective cohort study included 9305 pregnant women from 13 hospitals across India. Self-reported maternal socio-demographic and lifestyle factors, and maternal medical and obstetric histories from medical records were obtained at recruitment (≥28 weeks of gestation), and women were followed up within 48 h after childbirth. Maternal and fetal clinical information were classified based on guidelines into four groups of clinical factors: (i) ≥2 indications, (ii) one indication, (iii) no indication and (iv) contraindication. Associations of clinical and non-clinical factors (socio-demographic, healthcare utilisation and lifestyle related) with labour induction and augmentation were investigated using multivariable logistic regression analyses. Findings: Over two-fifths (n = 3936, 42.3%, 95% confidence interval [CI] 41.3-43.3%) of the study population experienced labour induction and more than a quarter (n = 2537, 27.3%, 95% CI 26.4-28.2%) experienced augmentation. Compared with women with ≥2 indications, those with one (adjusted odds ratio [aOR] 0.50, 95% CI 0.42-0.58) or no indication (aOR 0.24, 95% CI 0.20-0.28) or with contraindications (aOR 0.12, 95% CI 0.07-0.20) were less likely to be induced, adjusting for non-clinical characteristics. These associations were similar for labour augmentation. Notably, 34% of women who were induced or augmented did not have any clinical indication. Several maternal demographic (age at labour, parity and body mass index in early pregnancy), healthcare utilization (number of antenatal check-ups, duration of iron-folic acid supplementation and individuals managing childbirth) and socio-economic factors (religion, living below poverty line, maternal education and partner's occupation) were independently associated with labour induction and augmentation. Interpretation: Although decisions about induction and augmentation of labour in our study population in India were largely guided by clinical recommendations, we cannot ignore that more than a third of the women did not have an indication. Decisions could also be influenced by non-clinical factors which need further research.

Perceptions of healthcare professionals regarding labour induction and augmentation: A qualitative systematic review.

BACKGROUND: Labour induction and augmentation procedures are commonly used in maternity units with or without medical indications. Research shows that healthcare professionals play a significant role in women's childbirth decisions. AIM: To consolidate healthcare professionals' perceptions about labour induction and augmentation. METHODS: Seven electronic databases were searched from their inception dates till January 2023: PubMed, Embase, CINAHL, PsycINFO, Web of Science, Scopus, ProQuest Dissertations, and Theses Global. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis and Sandelowski and Barroso's guidelines guided this review. Included studies' quality was appraised by the Critical Appraisal Skills Program tool. Data were thematically synthesised. Review findings were assessed using the Grading of Recommendations Assessment, Development, and Evaluation-Confidence in the Evidence from Reviews of Qualitative research approach. FINDINGS: Three main themes were identified from the 17 included studies: 1) Making sense of the phenomenon, 2) Two sides of the coin, and 3) The enlightened path ahead. DISCUSSION: Healthcare professionals' labour induction and augmentation decisions were affected by personal (knowledge and moral philosophies), and external factors (women, community members, colleagues, and healthcare institutions). Some clinicians were unfamiliar with the proper labour induction/augmentation procedures, while others were worried about their decisions and outcomes. CONCLUSION: Suggestions for improvement include conducting labour induction/augmentation training for clinicians, having sufficient resources in facilities, and developing appropriate labour induction/augmentation clinical guidelines. Women and their partners, community members, and traditional healers could benefit from receiving labour induction/augmentation education. To improve health outcomes, healthcare professionals could deliver woman-centred care and collaborate.

Extended balloon labour induction: A single arm proof of concept trial.

Background: Mechanical labour induction with a transcervical balloon is as effective as pharmacological methods, with fewer adverse effects. Its use has been limited to labour induction with an unfavourable cervix able to retain the balloon. We have developed an innovative approach using 2-3 balloons side-by-side to extend the benefits of mechanical labour induction/augmentation with a favourable cervix without having to resort to amniotomy or uterotonics. Objectives: To assess the effectiveness of side-by-side balloons for extended labour induction/augmentation. Methods: We conducted a single arm proof of concept trial at Princess Marina Hospital (PMH) in Gaborone, Botswana. Participants were assessed as unsuitable for single balloon labour induction based on a modified Bishop cervical score of 7 or more. Three Foley catheters taped symmetrically side by side were passed through the cervix and inflated with 60mls each. Traction was applied with a weight of 250mls water suspended over the bed-end. The use of uterotonics, time from induction to birth, mode of birth, Apgar scores and adverse maternal and neonatal outcomes were recorded. Participants' satisfaction with the method of labour induction was assessed using a descriptive scale. Results: We enrolled 20 participants of whom two were nulliparous. Indications for labour induction were mainly late term (70%) and hypertensive disorders of pregnancy (25%). The mean cervical score was 7.2. Overall, 17 (85%) of the participants achieved a vaginal birth, of whom 5 required oxytocin for labour augmentation. Four of these had requested removal of the balloons, one due to discomfort and three felt the process was taking too long. Three participants underwent caesarean birth. The mean time from initiation of labour induction to vaginal birth was 16 h (standard deviation (SD) 8.4) and 20 h for caesarean birth (SD 10.5). There were no 5-minute Apgar scores below 7 nor neonatal admissions. One baby required brief resuscitation. There were no adverse maternal outcomes. Conclusion: This proof-of-concept study suggests that use of side-by-side balloons in participants with favourable cervix is effective in achieving vaginal birth in most participants without uterotonics or amniotomy. There were no adverse outcomes, though the study was too small to exclude the possibility of rare adverse outcomes. This offers a novel option for labour induction/augmentation, particularly where uterotonics or amniotomy are best avoided such as prior caesarean birth, vertical infection transmission risk and in settings with limited capacity for fetal surveillance. The results clearly justify larger randomized trials to evaluate this novel approach with greater precision. On the basis of the current study we are developing a purpose-designed balloon for extended balloon labour induction.

A nationwide, prospective, cohort study on exogenous oxytocin and delays in early child development: the Japan environment and children's study.

Although it remains debatable, exogenous oxytocin, commonly used for labour induction and augmentation, reportedly increases risks of neurodevelopment delay, attention-deficit/hyperactivity disorder, and autism spectrum disorder among children prenatally exposed to exogenous oxytocin. However, only few studies have objectively examined exogenous oxytocin's impact on early childhood development through scoring evaluations. This study investigated the association between exogenous oxytocin exposure and neurodevelopment in 3-year-old children using the Ages and Stages Questionnaires, Third Edition. In this nationwide prospective cohort study, we extracted data from 104,062 foetal records regarding exogenous oxytocin use during labour from the Japan Environment and Children's Study. Participants completed questionnaires throughout the pregnancy and postpartum periods. Outcomes comprised the developmental status less than each cut-off value for the five domains of the Ages and Stages Questionnaire, Third Edition. We conducted multivariable logistic regression analyses on the data of 55,400 children after controlling for confounders. Among the 55,400 included women, 19.0% (n = 10,506) used exogenous oxytocin during labour and 81.0% (n = 44,894) did not. Children exposed to exogenous oxytocin showed no significantly increased risk of developmental delay in any domain (communication: odds ratio [OR] 1.04, 95% confidence interval [CI] 0.92-1.16; gross motor: OR 0.97, 95% CI 0.87-1.08; fine motor: OR 1.00, 95% CI 0.92-1.09; problem-solving: OR 1.02, 95% CI 0.94-1.11; personal-social: OR 0.91, 95% CI 0.80-1.03).   Conclusion: Exogenous oxytocin for labour induction did not adversely affect early childhood development. Further studies accounting for the degree of exogenous oxytocin exposure are required to confirm these results. What is Known: • In developed countries, labour is induced in 20-25% of all pregnancies, for which oxytocin is commonly used. • Studies have associated risks of neurodevelopment delay, attention-deficit/hyperactivity disorder, and autism spectrum disorder with exposure to exogenous oxytocin. What is New: • Evaluation with the Ages and Stages Questionnaire, Third Edition, revealed that exogenous oxytocin use did not adversely affect early childhood development. • This prospective study reinforced the lack of evidence of an association between exogenous oxytocin use and early childhood development after adjustment for confounding and rigorous bias elimination.

The role of traditional complementary physical interventions in obstetrics - A scientific review commissioned by the European board and college of obstetrics and gynaecology (EBCOG).

Because of the fear of the use of pharmacological agents, many pregnant women are opting to use alternative management modalities either as primary management or to compliment standard contemporary medical practices. The traditional complementary physical interventions of acupuncture, acupressure, and electrostimulation have a long tradition of use in traditional Chinese medical practice and are advocated for the management of antenatal conditions such as spontaneous miscarriages, gastrointestinal, respiratory, and urinary problems. They have also been advocated as useful to help the process of labour in promoting a cephalic delivery, induction/augmentation of labour and pain relief. Postpartum these modalities have been said to help the secretion and production of milk. While a number of studies, some randomized controlled, have suggested a potential role for these traditional complementary physical interventions, systematic reviews have generally failed to show a definite conclusive beneficial role and all reviews generally suggest the need for further controlled research in the field. Since no adverse effects appear to be associated with the use of these modalities in pregnancy, such modalities of management can be considered but only as an adjuvant to standard pharmacological management after a full clinical assessment has ruled out underlying pathology.

Accelerated Titration of Oxytocin in Nulliparous Women with Labour Dystocia: Results of the ACTION Pilot Randomized Controlled Trial.

OBJECTIVE: The primary objective was to determine the feasibility of a large RCT assessing the effectiveness of an accelerated oxytocin titration (AOT) protocol compared with a standard gradual oxytocin titration (GOT) in reducing the risk of CS in nulliparous women diagnosed with dystocia in the first stage of labour. The secondary objective was to obtain preliminary data on the safety and efficacy of the foregoing AOT protocol. METHODS: This was a multicentre, double-masked, parallel-group pilot RCT. This study was conducted in three Canadian birthing centres. A total of 79 term nulliparous women carrying a singleton pregnancy in spontaneous labour, with a diagnosis of labour dystocia, were randomized to receive either GOT (initial dose 2 mU/min with increments of 2 mU/min) or AOT (initial dose 4 mU/min with increments of 4 mU/min), in a 1:1 ratio. An intention-to-treat analysis was applied. RESULTS: A total of 252 women were screened and approached, 137 (54.4%) consented, and 79 (31.3%) were randomized. Overall protocol adherence was 76 of 79 (96.2%). Of the women randomized, 10 (25.6%) allocated to GOT had a CS compared with six (15.0%) allocated to AOT (Fisher exact test P = 0.27). CONCLUSION: This pilot study demonstrated that a large, multicentre RCT is not only feasible, but also necessary to assess the effectiveness and safety of an AOT protocol for labour augmentation with regard to CS rate and indicators of maternal and perinatal morbidities.
