Prevalence of macrosomic newborn and maternal and neonatal complications in a high-risk maternity

Abstract Objective Evaluate the prevalence of macrosomic newborns (birth weight above 4000 grams) in a high-risk maternity from 2014 to 2019, as well as the maternal characteristics involved, risk factors, mode of delivery and associated outcomes, comparing newborns weighing 4000-4500 grams and those weighing above 4500 grams. Methods This is an observational study, case-control type, carried out by searching for data in hospital's own system and clinical records. The criteria for inclusion in the study were all patients monitored at the service who had newborns with birth weight equal than or greater than 4000 grams in the period from January 2014 to December 2019, being subsequently divided into two subgroups (newborns with 4000 to 4500 grams and newborns above 4500 grams). After being collected, the variables were transcribed into a database, arranged in frequency tables. For treatment and statistical analysis of the data, Excel and R software were used. This tool was used to create graphs and tables that helped in the interpretation of the results. The statistical analysis of the variables collected included both simple descriptive analyzes as well as inferential statistics, with univariate, bivariate and multivariate analysis. Results From 2014 to 2019, 3.3% of deliveries were macrosomic newborns. The average gestational age in the birth was 39.4 weeks. The most common mode of delivery (65%) was cesarean section. Diabetes mellitus was present in 30% of the deliveries studied and glycemic control was absent in most patients. Among the vaginal deliveries, only 6% were instrumented and there was shoulder dystocia in 21% of the cases. The majority (62%) of newborns had some complication, with jaundice (35%) being the most common. Conclusion Birth weight above 4000 grams had a statistically significant impact on the occurrence of neonatal complications, such as hypoglycemia, respiratory distress and 5th minute APGAR less than 7, especially if birth weight was above 4500 grams. Gestational age was also shown to be statistically significant associated with neonatal complications, the lower, the greater the risk. Thus, macrosomia is strongly linked to complications, especially neonatal complications.

Obstetric Paralysis: Who is to blame? A systematic literature review / Paralisia obstétrica: De quem é a culpa? Uma revisão sistemática de literatura

Abstract Obstetric palsy is classically defined as the brachial plexus injury due to shoulder dystocia or to maneuvers performed on difficult childbirths. In the last 2 decades, several studies have shown that half of the cases of Obstetric palsy are not associated with shoulder dystocia and have raised other possible etiologies for Obstetric palsy. The purpose of the present study is to collect data from literature reviews, classic articles, sentries, and evidence-based medicine to better understand the events involved in the occurrence of Obstetric palsy. A literature review was conducted in the search engine PubMed (MeSH - Medical Subject Headings) with the following keywords: shoulder dystocia and obstetric palsy, completely open, boundless regarding language or date. Later, the inclusion criterion was defined as revisions. A total of 21 review articles associated with the themes described were found until March 8, 2018. Faced with the best available evidence to date, it is well-demonstrated that Obstetric palsy occurs in uncomplicated deliveries and in cesarean deliveries, and there are multiple factors that can cause it, relativizing the responsibility of obstetricians, nurses, and midwives. The present study aims to break the paradigms that associate Obstetric palsy compulsorily with shoulder dystocia, and that its occurrence necessarily implies negligence, malpractice or recklessness of the team involved.

Resumo A paralisia obstétrica é classicamente definida como a lesão do plexo braquial decorrente da distócia de ombros ou das manobras executadas no parto difícil. Nas 2 últimas décadas, vários estudos comprovaram que metade dos casos de paralisia obstétrica não estão associados à distócia de ombros e levantaram outras possíveis etiologias para a paralisia obstétrica. O objetivo do presente trabalho é colher dados da literatura de revisão, artigos clássicos, sentinelas e da medicina baseada em evidências para compreender melhor os eventos envolvidos na ocorrência de paralisia obstétrica. Foi realizada uma revisão da literatura no motor de busca da PubMed (MeSH - Medical Subject Headings) com as seguintes palavras-chave: shoulder dystocia and obstetric palsy, completamente aberto, sem limites de língua ou data. Posteriormente, definimos como critério de inclusão artigos de revisão. Encontramos 21 artigos de revisão com associação dos temas descritos até 8 de março de 2018. Frente às melhores evidências existentes até o momento, está bem demonstrado que a paralisia obstétrica ocorre em partos não complicados e em partos cesáreos, e são múltiplos os fatores que podem causá-la, relativizando a responsabilidade de médicos obstetras, enfermeiras e parteiras. Procuramos, com o presente estudo, quebrar os paradigmas de que paralisia obstétrica se associa obrigatoriamente à distócia de ombros e que a sua ocorrência necessariamente implica em negligência, imperícia ou imprudência da equipe envolvida.

The Association of Clavicle Fracture With Brachial Plexus Birth Palsy.

PURPOSE: Shoulder dystocia is the strongest known risk factor for brachial plexus birth palsy (BPBP). Fractures of the clavicle are known to occur in the setting of shoulder dystocia. It remains unknown whether a clavicle fracture that occurs during a birth delivery with shoulder dystocia increases the risk of BPBP or, alternatively, is protective. The purpose of this study was to use a large, national database to determine whether a clavicle fracture in the setting of shoulder dystocia is associated with an increased or decreased risk of BPBP. MATERIALS AND METHODS: The 1997 to 2012 Kids' Inpatient Database (KID) was analyzed for this study. International Classification of Diseases, Ninth Revision (ICD-9) codes were used to identify newborns diagnosed with shoulder dystocia and BPBP as well as a concurrent fracture of the clavicle. Newborns with shoulder dystocia were stratified into 2 groups: dystocia without a clavicle fracture and dystocia with a clavicle fracture. Multivariable logistic regression was used to quantify the risk for BPBP among shoulder dystocia subgroups. RESULTS: The dataset included 5,564,628 sample births extrapolated to 23,385,597 population births over the 16-year study period. A BPBP occurred at a rate of 1.2 per 1,000 births. Shoulder dystocia complicated 18.8% of births with a BPBP. A total of 7.84% of newborns with a BPBP also sustained a clavicle fracture. Births with shoulder dystocia and a clavicle fracture incurred BPBP at a rate similar to that for newborns with shoulder dystocia and no fracture (9.82% vs 11.77%). Shoulder dystocia without a concurrent clavicle fracture was an independent risk factor for BPBP (odds ratio, 112.1; 95% confidence interval, 103.5-121.4). Those with shoulder dystocia and clavicle fracture had a risk for BPBP comparable with those with shoulder dystocia but no fracture (odds ratio, 126.7 vs 112.1). CONCLUSIONS: This population-level investigation suggests that, among newborns with shoulder dystocia, clavicle fracture is not associated with a significant change in the risk of BPBP. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Perfil clínico y resultado perinatal en pacientes conducidas con oxitocina por distocias dinámicas en el Hospital Nacional de la Mujer en el periodo de julio a septiembre de 2016 / Clinical profile and perinatal outcome in patients treated with oxytocin for dynamic dystocia at the National Women's Hospital in the period from July to September 2016

En el hospital Nacional de la Mujer como centro de tercer nivel de atención en salud, uno de sus funciones es garantizar un buen resultado materno ­ perinatal en pacientes que consultan para la atención del parto, muchas veces durante el trabajo de parto ocurren situaciones como distocias dinámicas que no permiten el adecuado progreso de este, por lo cual hace necesario la utilización de oxitocina para mejorar la actividad uterina y poder garantizar un buen resultado materno- perinatal; muchas veces el uso inadecuado de esta puede poner en riesgo la salud de la madre y el feto, interfiriendo en la vía de finalización del parto y otras complicaciones que prolonga la estancia intrahospitalaria generando gastos extras a la institución. En el presente estudio se investigó, de manera retrospectiva, a través de revisión de expedientes clínicos, los resultados maternos- fetales así como la vía de finalización del embarazo en las pacientes en las cuales se utilizó oxitocina como conducción por distocia dinámica durante el trabajo de parto. Se incluyó solo embarazos únicos y de término; dentro de los resultados se obtuvo la detención de la fase activa como principal distocia dinámica para indicación de conducción con oxitocina durante el trabajo de parto. La principal indicación de evacuación vía abdominal fue deterioro fetal; la complicación materna más frecuente fue atonía uterina, la más severa fue hemorragia obstétrica severa que resolvieron con manejo médico. La mayoría de los recién nacidos fueron niño sano
