“…These include advanced maternal age, obesity, diabetes, abnormalities of second-stage labor, vacuum-or forceps-assisted delivery, and shoulder dystocia. 20,27,28,40,43 Factors that have been suggested to be protective against NBPP include twin or multiple births and cesarean delivery. 16 Though this wide range of factors has been suggested, none have been consistently shown to be predictive of NBPP occurrence.…”

OBJECTIVE Neonatal brachial plexus palsy (NBPP) occurs due to the stretching of the nerves of the brachial plexus before, during, or after delivery. NBPP can resolve spontaneously or become persistent. To determine if nerve surgery is indicated, predicting recovery is necessary but difficult. Historical attempts explored the association of recovery with only clinical and electrodiagnostic examinations. However, no data exist regarding the neonatal and peripartum factors associated with NBPP persistence. METHODS This retrospective cohort study involved all NBPP patients at the University of Michigan between 2005 and 2015. Peripartum and neonatal factors were assessed for their association with persistent NBPP at 1 year, as defined as the presence of musculoskeletal contractures or an active range of motion that deviated from normal by > 10° (shoulder, elbow, hand, and finger ranges of motion were recorded). Standard statistical methods were used. RESULTS Of 382 children with NBPP, 85% had persistent NBPP at 1 year. A wide range of neonatal and peripartum factors was explored. We found that cephalic presentation, induction or augmentation of labor, birth weight > 9 lbs, and the presence of Horner syndrome all significantly increased the odds of persistence at 1 year, while cesarean delivery and Narakas Grade I to II injury significantly reduced the odds of persistence. CONCLUSIONS Peripartum/neonatal factors were identified that significantly altered the odds of having persistent NBPP at 1 year. Combining these peripartum/neonatal factors with previously published clinical examination findings associated with persistence should allow the development of a prediction algorithm. The implementation of this algorithm may allow the earlier recognition of those cases likely to persist and thus enable earlier intervention, which may improve surgical outcomes.

“…No hay consenso en la literatura revisada la relación trauma obstétrico relacionado a la variable edad materna (14). Se destaca que las mujeres con edad superior a 35 años se relacionan a mayor número de casos de parálisis del plexo braquial, aunque no haya sido observada diferencia estadísticamente significativa entre las primíparas y las multíparas (17).…”

“…Vale resaltar que los traumatismos también pueden ocurrir por ocasión de partos abdominales, más frecuentemente en cirugías de emergencia (11). Para algunos autores, la incidencia de traumatismos relativa a la vía de parto no presentó diferencia estadística, cuando el parto vaginal ocurrió con el auxilio de fórceps o vacuo ex-tractor (2,8% vs. 1,3%, p=0,303) (6,7,12,17).…”

RESUMENAntecedentes: Se define trauma al nacimiento las lesiones sufridas por el feto durante el trabajo de parto o expulsión. Objetivo: Identificar los factores de riesgo asociados a lesiones originadas durante el nacimiento en recién nacidos. Método: Estudio casos y controles, realizado en el período de julio/2004 a diciembre/2005, en la División de Ginecología y Obstetricia del Hospital General de Caxias do Sul/ Facultad de Medicina, Universidad de Caxias do Sul, RS, Brasil. Fueron analizadas variables maternas, del parto y fetales, utilizando el programa estadístico SPSS versión 19.0. Los factores que obtuvieron nivel significativo <0,10 en los análisis bivariado fueron insertas en la regresión logística. Se utilizó el modelo de entrada por bloques (block entry) para selección del modelo final de la regresión. Resultados: En el período citado nacieron 2.137 infantes, 26 de ellos (1,2%) sufrieron trauma al nacimiento. La fractura de clavícula fue la lesión más frecuente (n=14; 53,8%), seguida del cefalohematoma (n=5; 19,2%). Las variables gasométricas no presentaron diferencia estadística. En la regresión logística, las únicas variables independientes asociadas a traumatismo al nacimiento fueron parto vaginal (OR-A: 11,08; IC95%: 2,45-49,98; p=0,002) y perímetro torácico ≥33 cm 36; IC95%: 1,73; p=0,010). Conclusión: Los factores de riesgo asociados a lesiones durante el nacimiento involucran el parto vaginal y el perímetro torácico igual o superior a 33cm. PALABRAS CLAVE: Traumatismo, factores de riesgo, estudios de casos y controles, embarazo SUMMARYBackground: Obstetrics injuries can be defined as fetal lesions suffered by the fetus during labor or expulsion. Objective: Identify risk factors for fetal birth trauma. Method: Case-control study conducted from July 2004 to December 2005. We analyzed maternal and fetal variables using software SPSS 19.0. The variables showing a significance level <0.10 in the bivariate analysis were included in the logistic regression analysis. We used the block entry model for selection of the final regression model. Results: During these period, we identified 2137 births and 26 (1.2%) were related to fetal birth injury. Clavicle fracture was the most frequent injury (n = 14; 53.8%), followed by cephalohematoma (n = 5; 19.2%). Umbilical cord blood gas analysis did not show statistical significance. In the regression analysis of the variables that had significance level <0.10, the only independent variables associated with fetal birth injury were vaginal delivery (OR-A: 11.08; 95%CI: 2.45-49.98; p=0.002) and thorax circumference ≥ 33 cm (OR-A: 3.36; 95%CI: 1.35-9.73; p=0.010). Conclusion: The risk factors for fetal birth injury were vaginal delivery and chest circumference equal to or larger than 33 cm. Other variables were not associated with the outcome in discussion.

“…While there is no difference in gender of the newborns with BPP, most cases occur in spontaneous deliveries. BPP which develops in the newborn associated with insufficient placenta is known as Kaiser Wilhelm syndrome and is included in the obstetric BPP group [1,2].…”
