Resumen
En la etiología y desarrollo de la preeclampsia-eclampsia se desarrollan eventos que favorecerían la alteración del intercambio gaseoso a nivel placentario lo que determinaría que la frecuencia de estas alteraciones sea mucho más alta que en la población general. Siendo el hospital GinecoObstétrico “Enrique C. Sotomayor” una institución de atención especializada que atiende anualmente aproximadamente 4000 mujeres embarazadas con preeclampsia se debía establecer si existía asociación entre el estado ácidobásico en los productos de estas pacientes y el resultante perinatal. Se ejecutó un estudio de tipo observacional, descriptivo, correlacional de diseño no experimental longitudinal retrospectivo en el que se incluyeron los casos de neonatos nacidos de madres con preeclampsia. Para el análisis estadístico se calcularon frecuencias simples, porcentajes y promedio y se emplearon las Prueba de Chi2 y Test exacto de Fisher considerándose significativos valores de P <0.05. La prevalencia de acidosis reportada en sangre arterial de cordón umbilical de neonatos de madres con preeclampsia eclampsia fue del 52%. Las variables como edad, sexo neonatal, condición nutricional al nacer, tipo de preeclampsia-eclampsia, uso de sulfato de magnesio y el uso de oxitocina durante el trabajo de parto, en el grupo de pacientes con y sin acidosis fue similar (P > 0.05). Existió una diferencia significativa entre el grupo con trastorno del estado ácido básico y el que no la desarrollo en relación a la puntuación de Apgar al minuto menor a 8 (76% y 36%; P 0,001) y necesidad de reanimación (21% y 0%; P 0.006). No existieron diferencias estadísticamente significativas (P> 0.05) en relación a puntuación de Apgar a los 5 minutos (12% y 6%); ingreso a TIN (2% y 0%); necesidad de entubación (6% y 0%)

The Sotomayor hospital facility serves annually approximately 4000 preeclampsia – pregnant with should be established if there was a relationship between acid-base status in the products of these patients and the perinatal outcome. The statistical analysis was calculated when the frequency simple percentages and mean, and were used Chi2 test and Fisher exact test considering significant values of P <0.05. The reported prevalence of acidosis in umbilical cord arterial blood of infants of mothers with preeclampsia eclampsia was 52%. Variables such as age, neonatal sex, nutritional status at birth, type of pre-eclampsia, magnesium sulfate use and use of oxytocin during labor, in the group of patients with and without acidosis was similar (P> 0.05 .) There was a significant difference between the group with mood disorders acid-base and not the development in relation to minute Apgar score less than 8 (76% and 36%, P 0.001) and resuscitation (21% and 0 %, P 0.006). No statistically significant differences (P> 0.05) in relation to Apgar score at 5 minutes (12% and 6%) TIN income (2% and 0%), need for intubation (6% and 0%)
