Opioid use during pregnancy has serious consequences for mother and baby. The true extent of the problem is unknown and there is a need for better screening. Existing guidelines with respect to the management of pregnant women with opioid use are based on limited evidence. To improve recommendations for optimal identification, management, and treatment, publications on opioids in pregnancy were reviewed. Published literature from 2007 to 2017 was searched in PubMed, Cochrane and Embase databases. The review employed 60 publications from 210 studies identified, that were of varying quality and included randomized controlled trials, systematic reviews, meta-analyses, and Cochrane reviews. The prevalence of opioid use in pregnancy is underestimated. Screening by urine testing and self-reporting is acceptable to identify fetal exposure. To minimize risk, opioid agonist pharmacotherapy should replace the continued use of opioids or detoxification. Current guidelines recommend methadone and buprenorphine equally. However, recent studies indicate that buprenorphine has advantages over methadone. Accordingly, we suggest buprenorphine as first-line therapy. Future studies should elaborate on better objective screening methods to prevent the consequences of fetomaternal opioid exposure. [ABSTRACT FROM AUTHOR]

Introduction Material and Methods Results Conclusions Obstetric violence, or mistreatment of women in obstetric care, can have severe consequences such as fear of future childbirth, post‐traumatic stress disorder, and depression.The primary objective was to estimate the prevalence of obstetric violence in high‐income countries. The secondary objective was to extract the main domains of obstetric violence perceived by women from qualitative studies. Following prospective registration (PROSPERO CRD42023468570), PubMed, Web of Science, Scopus, CINAHL, Embase, and Cochrane Library were searched with no restrictions. Included studies were cross‐sectional, cohort, mixed methods, and qualitative studies based on populations from high‐income countries. The review was conducted by two independent reviewers. Risk of bias was assessed. Rates of obstetric violence were pooled using random effects model, computing 95% confidence intervals (CI) and assessing heterogeneity using I2 statistic. Funnel plots and Egger's test were used to detect potential reporting biases and small‐study effects.Of the 1821 records screened, 25 studies were included: 14 quantitative and 2 mixed methods studies, comprising 60 987 women, and 9 qualitative studies were included, comprising an additional 4356 women. 81.25% of quantitative studies, including the quantitative component of the mixed methods studies, were considered satisfactory or better regarding risk of bias. The prevalence of obstetric violence was overall 45.3% (95% CI 27.5–63.0; I2 = 100.0%). The prevalence of specific forms of mistreatment was also estimated. Lack of access to analgesia was 17.3% (95% CI 6.9–27.7; I2 = 99.7%). Ignored requests for help was 19.2% (95% CI 11.7–26.6; I2 = 99.0%). Shouting and scolding 19.7% (95% CI 13.0–26.4; I2 = 98.7%). The use of fundal pressure during the second stage of labor (Kristeller maneuver) was 30.3% (95% CI 22.1–38.5; I2 = 97.6%). There was no funnel asymmetry. Lack of information and/or consent were the most frequent domains extracted from the qualitative articles and the qualitative component of the mixed methods studies.The results demonstrate that obstetric violence is a prevalent problem that women in high‐income countries experience. Lack of information and/or consent were the domains most frequently described in the qualitative studies and the qualitative component of the mixed methods studies. [ABSTRACT FROM AUTHOR]
