Resumen
Dentro de las causas que pueden provocar Sufrimiento Fetal Agudo, tenemos aquellas que determinan una disminución del aporte de sangre al útero en cantidad y calidad, como es la preeclampsia, que produce disminución de la llegada de sangre al útero, pacientes diabéticas o hipertensas, como así también mujeres con anemia o problemas pulmonares que provocan falta de oxígeno en la sangre. La transferencia de oxígeno en la placenta se realiza por difusión simple. La circulación sanguínea fetal se caracteriza por un flujo de sangre rápido, facilitado por la baja presión sanguínea fetal, que junto con la baja saturación de oxígeno y la elevada concentración de hemoglobina fetal aumenta y facilita el transporte de oxígeno a los tejidos. . Material y métodos. 2 grupos de 80 pacientes con gráfica insatisfactoria, comparables entre sí. En el primero se realizó el seguimiento del parto bajo pHmetría seriada, y en el otro grupo, los controles de los fetos se realizaron de forma conjunta con pHmetría y pulsioximetría. Resultados: estadísticamente significativos en la vía del parto en el estudio comparativo de ambos grupos. Atendiendo a los resultados perinatales obtenidos, los datos indican que no existen diferencias significativas en los valores de pH de arteria umbilical ni en los valores del Apgar al minuto y a los 5 minutos del parto entre los dos grupos, por lo cual ambos protocolos son igualmente satisfactorios. La correlación de los datos obtenidos por pHmetría con los de la pulsioximetría, fue estadísticamente significativa. Conclusiones. El proceso de oxigenación fetal inicia desde el medio ambiente hasta la célula fetal incluyendo el intercambio útero placentario, transporte de oxígeno por la sangre fetal, la transferencia y el consumo en los tejidos fetales. Se recomienda diseñar estrategias de prevención para evitar la mortalidad neonatal por el efecto del parto sobre la oxigenación fetal.

Among the causes that can cause fetal distress, we have those that determine a decrease in blood supply to the uterus in quantity and quality, such as preeclampsia, which produces decreased blood supply to the uterus, diabetic or hypertensive patients, as well women with anemia or lung problems that cause lack of oxygen in the blood. Oxygen transfer in the placenta is performed by simple diffusion. The fetal circulation is characterized by a rapid blood flow, facilitated by the low fetal blood pressure, together with the low oxygen saturation and the high concentration of fetal hemoglobin increases and facilitates the transport of oxygen to tissues. . Material and methods. 2 groups of 80 patients with unsatisfactory graph, comparable. In the first delivery tracking serial low pH monitoring it was performed, and in the other group, controls fetuses were conducted jointly with pH monitoring and pulse oximetry. Results: Statistically significant in the birth canal in the comparative study of both groups. Based on the perinatal results obtained, the data indicate no significant differences in pH values of umbilical artery or in the Apgar values at one minute and five minutes of labor between the two groups, which both protocols are equally satisfactory. The correlation of the data obtained by pH monitoring with pulse oximetry was statistically significant. Conclusions. The fetal oxygenation process starts from the environment to the cell including the uterus fetal placental exchange, oxygen transport by fetal blood, transfer and consumption in fetal tissues. It is recommended to design prevention strategies to prevent neonatal mortality effect of labor on fetal oxygenation. Keywords.
