Obstetric brachial palsy (OBP) is a lesion of the brachial plexus during the neonatal period associated to delivery.
Know the incidence of OBP in children born in the Materno Infantil University Hospital of the Canary Islands in the last 5 years, study the risk factors of pregnancy and delivery associated to OBP, make a review of the literature in order to compare the results obtained and follow the patient's evolution.
Observational retrospective study of all patients affected by OBP born at our hospital between January 2000 and December 2004. Data of the mother, newborn, type of delivery and lesion were recorded and compared with the rest of deliveries. Statistical analysis: we used the SPSS 13.0 program. Results are expressed as incidence of OBP per thousand, with confidence intervals at 95%. In addition, children affected by a transitory OBP (those who had been cured before one year) were analyzed separately from those affected by a permanent OBP (with clinical affectation persisting one year later).
A total of 49 patients affected by OBP were diagnosed. Incidence was 1.23 鈥? Statistically significant results were found between OBP incidence and high birth weight, use of forceps and the existence of Apgar's test and pH with lower than usual scores. At 12 months 86%of the patients presented symmetric mobility. No cases of distal palsies were found.
Brachial plexus lesions are related to the common risk factors. The results are similar to those found in the literature. Control of children with OBP is essential to minimize the appearance of sequelae.
