Insights
Most infants with obstetric brachial plexus injury recover, with permanent damage linked to shoulder dystocia. Parental caregiving burden for neonatal brachial plexus injury is typically low.
Area of Science:
- Obstetrics
- Neonatal Medicine
- Pediatric Neurology
Background:
- Obstetric brachial plexus injury (OBPI) is a significant cause of neonatal morbidity.
- Understanding associated maternal and perinatal factors is crucial for prevention and management.
- Clinical outcomes and parental impact require thorough investigation.
Purpose of the Study:
- To evaluate maternal and perinatal factors linked to obstetric brachial plexus injury.
- To analyze clinical follow-up outcomes in affected infants.
- To assess the parental caregiving burden associated with neonatal brachial plexus injury.
Main Methods:
- Retrospective descriptive study design.
- Analysis of 28 infants with obstetric brachial plexus injury from 27,695 live births (Feb 2018-Dec 2023).
- Inclusion of maternal demographics, delivery details, infant diagnoses, follow-up data, and parental-reported burden.
Main Results:
- Eighty-nine percent of affected infants had Erb's palsy.
- Eighty-six percent of infants recovered from injury within a mean 12-month follow-up.
- Permanent injury was significantly associated with shoulder dystocia (p=0.007).
- Most parents reported no to mild caregiving burden (78.6%).
Conclusions:
- The majority of infants with obstetric brachial plexus injury experience recovery.
- Shoulder dystocia is a key risk factor for permanent neonatal brachial plexus injury.
- Parental caregiving burden associated with neonatal brachial plexus injury is generally manageable.
Objective:
Obstetric brachial plexus injury is a significant cause of neonatal morbidity. The aim of this study was to evaluate the maternal and perinatal factors associated with plexus injury and to analyze clinical follow-up outcomes and parental caregiving burden.
Material And Methods:
This study was conducted as a retrospective descriptive study at the maternity center of a tertiary hospital. Deliveries resulting in obstetric plexus injury between February 2018 and December 2023 were included in the study. Out of 27,695 live births, 28 infants with plexus injury were identified and analyzed.
Results:
Of the women who gave birth to infants with brachial plexus injury, 25 (89.3%) were aged 21-34 years, and 22 (78.6%) had a body mass index between 25 and 29.99 kg/m2. Of the cohort, 16 (57.1%) were multiparous, and 3 (10.7%) had gestational diabetes. In addition, 15 (53.6%) women underwent labor induction, and all had vaginal deliveries. Shoulder dystocia occurred in 11 deliveries (39.3%). Of the newborns with brachial plexus injury, 25 (89.3%) had Erb's palsy. The mean follow-up period for the infants was 12 (3-31) months. Injury recovery occurred in 24 babies (85.7%), while four babies (14.3%) experienced permanent injury. Regarding parental caregiving burden, 22 parents (78.6%) reported "no to mild burden," while six parents (21.4%) reported a "mild to moderate burden." No parents reported "moderate to severe" or "severe burden". All newborns with permanent damage developed shoulder dystocia at delivery (p=0.007).
Conclusion:
Most infants with plexus injury recovered, while permanent injury was linked to shoulder dystocia, and parental caregiving burden was generally low.
