Resumen

NOVOA P, José M et al. ¿Es posible disminuir la Incidencia de Encefalopatía Hipóxico Isquémica?. Rev. chil. obstet. ginecol. [online]. 2017, vol.82, n.1, pp.51-57. ISSN 0717-7526.  http://dx.doi.org/10.4067/S0717-75262017000100007.

Objectives: Determine whether a local policy to reduce the incidence of neonatal hypoxic-ischemic encephalopathy (HIE), established at the Maternity Unit of Hospital Padre Hurtado (HPH), is effective without significantly increasing the cesarean rate. Design: Cohort study. Setting: Maternity unit of Hospital Padre Hurtado. Population: Newborns older than 33 weeks born at Hospital Padre Hurtado between 1999 and 2015. Methods: The results of a training policy to prevent HIE and perinatal asphyxia established at the Maternity unit of Hospital Padre Hurtado were reviewed during a period of 14 years. Results: From a total of 102.612 newborns analyzed, results showed a decrease in all grades of HIE incidence, from a rate of 4.75 / 1,000 live births prior to intervention (control group) to a rate of 1.46 per 1,000 live births after interventions, with high statistically significance (p=0.008), it reached an average rate of 0.87/1000 for the last 6 years. The moderate and severe HIE rate decreased from 1.15/1000 to 0.62/1000, also with high statistically significance (p=0.02). During the same period of time, the cesarean rate varied between 26-29%. Conclusion: The introduction of protocolized and systematized interventions trough the implantation of Management guides, obstetrics emergency trainings to the professional team and continues audit of the HIE cases at the Maternity unit Hospital Padre Hurtado was associated to a significant decrease of HIE, maintaining the rate of cesareans below 30%.
