Brachial Plexus Birth Injury: Epidemiology and Birth Weight Impact on Risk Factors

Background: Brachial plexus birth injury (BPBI) is a condition in which the brachial plexus is thought to be damaged during the birth process. Studies have cited a varying incidence rate ranging from 0.5 to 4.0 per 1000 live births. The purpose of this study is to evaluate birth claims data over a 15-year period to identify risk and protective factors for BPBI in the state of Colorado. Methods: A data request was made to the state hospital association for birth claims data. We requested all birth claims from the years 2000 to 2014. ICD9 codes for variables of interest included: BPBI, shoulder dystocia, heavy-for-dates, macrosomia, breech delivery, instrumented birth, birth hypoxia, and gestational diabetes. A multivariable logistic regression model quantified both risk and protective factors for the development of BPBI as odds ratios (ORs) with 95% confidence intervals (CI). Results: There were 966,447 birth records received from State Hospital Association. The BPBI incidence was 0.63/1000 live births. The mean (SD) birth weight was 3187 (572) g for the total population and 3808 (643) g for the BPBI births. Later admission year indicated a decrease in BPBI births (OR, 0.94; 95% CI: 0.92, 0.96/y). Asian, black, and Hispanic infants were more likely to have a BPBI than white infants. Shoulder dystocia (OR, 60.37; 95% CI: 47.90, 76.13) was the highest risk factor for BPBI followed by instrumented forceps birth (OR, 21.04; 95% CI: 12.22, 36.21), breech deliv...

This study was aimed to assess whether the “39-week” rule is being extended to high-risk pregnancies and if so whether this has led to changes in neonatal morbidity or stillbirth. Study Design Birth certificate data between 2010 and 2014 from 23 states (55% of births in the United States) were used. Pregnancies were classified as high risk if they had any one of the following: maternal age greater than or equal to 40 years, prepregnancy body mass index (BMI) greater than or equal to 40 kg/m2, chronic (prepregnancy) hypertension, or diabetes (pregestational or gestational). Delivery timing changes...

AbstractPurposeWhile the increased rates of high degree perineal tears were previously associated with the use of forceps, in the current era of low volume of forceps practice, factors associated with the occurrence of this potential complication remain understudied. We aim to evaluate factors associated with obstetric anal sphincter injury (OASIS) in obstetric units with a low volume forceps practice.MethodsA retrospective cohort study was conducted at two tertiary medical centers. All singleton pregnancies delivered by forceps extraction between 2011 and 2019 were analyzed. Women who experienced anal sphincter injury wer...

Authors: Abstract Exercise, defined as physical activity consisting of planned, structured, and repetitive bodily movements done to improve one or more components of physical fitness, is an essential element of a healthy lifestyle, and obstetrician-gynecologists and other obstetric care providers should encourage their patients to continue or to commence exercise as an important component of optimal health. Women who habitually engaged in vigorous-intensity aerobic activity or who were physically active before pregnancy can continue these activities during pregnancy and the postpartum period. Observational studie...

AbstractBackgroundIreland has changed over the past sixty  years, and the dynamic practice of obstetrics and gynaecology has changed with it.Study design and methodsTo describe these changes, a review was performed of clinical reports of a tertiary referral teaching hospital over six decades.ResultsSince the 1960s, the hospital ’s total births per annum has risen (3050 to 8362 births). Teenage pregnancy is less common (4.7 to 2.0%,p

ConclusionAn attempt of vaginal birth is a reasonable option for short stature women. Maternal height could be included in the selection criteria for planned birth center or home birth.The customized gestational-related optimal weigh could be useful to identify large of gestational age fetus.

Authors: Huang SY, Yu B, He X, Chen Y Abstract To compare intrapartum results associated with differing degrees of ketonuria in nulliparous women with gestational diabetes mellitus (GDM), we implemented a retrospective cohort study comparing clinical characteristics among differing degrees of ketonuria and the duration and distribution of ketonuria at different stages of labor. We also analyzed adverse maternal and neonatal outcomes for each group. A total of 570 GDM deliveries were included; of these, 238 had negative ketonuria (41.8%), 180 had moderate ketonuria (31.6%), and 152 had ketosis (26.6%). The proportio...

The objective of this study is the generation of descriptive data on the mode of delivery and on maternal and foetal complications in the case of foetal macrosomia. The causes and consequences of foetal macrosomia as well as the rate of shoulder dystocia are examined in relation to the severity of the macrosomia. Patients The study investigated all singleton births ≥ 37 + 0 weeks of pregnancy with a birth weight ≥ 4000 g at the Charité University Medicine Berlin (Campus Mitte 2001 - 2017, Campus Virchow Klinikum 2014 - 2017).
