Abstract

Introduction: Erb-Duchenne paralysis is the most common form of neonatal brachial plexus palsy. Cesarean section is one of the protective factors in Erb paralysis.

Materials and Methods: The data were related to mothers who gave birth by both natural and cesarean section during the study period in Al-Zahra Hospital in Rasht, as well as their infants. The number of cases of Erb paralysis during one-month periods was identified and for the mentioned period, the interrupted time series analysis or ITSA method was calculated and its changes were measured. Other variables including maternal age at delivery, weight of newborns at birth and total number of deliveries by delivery method were extracted and recorded from the maternity and neonatal registry.

Results: In this study, 7 cases of neonatal paralysis were recorded, which indicates an incidence of 0.17 cases per 1000 births, of which 6 cases were registered after the implementation of the Health Transformation Plan. Considering the confounding variables, the number of cases of Erb paralysis during the period after the implementation of the health system transformation plan has an upward trend compared to before its implementation, which according to P = 0.079, this difference with a 90% confidence interval is significant. have been. Also, deliveries performed by cesarean section have increased from 60.1% before the transformation plan to 64.1% after the transformation plan.

Conclusion: This study showed that the incidence of Erb paralysis in Al-Zahra Center is lower than other incidence in other studies in other countries. Also, due to its higher incidence in normal deliveries, in addition to reducing the rate of cesarean section to maintain the health of mother and baby, special attention should be paid to increasing the likelihood of some complications following a normal delivery.
