Abstract

OBJECTIVE: Our purpose was to examine risk factors associated with brachial plexus injury (BPI) in a large population based study. STUDY DESIGN: Using a data set linking birth certificates with maternal and newborn hospital discharge records from acute care civilian hospitals in CA in 1992, newborns with the diagnosis of BPI at birth were identified. RESULTS: There were 446,404 vaginal births of which 854 (0.19%) had BPI. The mean gestational age at deliver)' was 40.0 weeks, and mean birth weight 3959 gms, both which were greater than the general population. Of the 854 cases of BPI, only 371 (43%) also had the diagnosis of shoulder dystocia (SD). BPI increased with increasing birthweight (BW) and with assisted delivery: Brachial plexus injury Assisted Unassisted 3500-4000 gms 0.54% 0.31% 4000-4500 gms 1.95% 1.03% 4500-5000 gms 5.80% 2.92% 5000+ -5.94% CONCLUSION: While the incidence of BPI increased (as expected) with increasing BW and assisted deliver)', interestingly, only 43% of BPI cases were associated with SD. This would suggest that either SD is under reported, or other factors are involved with BPI. The degree of permanent BPI could not be determined in this study but has been reported to be 5-10% of cases with BPI at birth.
