Excess Base Comparison Between Pregnant Subjects With Severe Preeclampsia vs. Normotensive Pregnant Women

Brief summary (registry, in English)

The study's primary goal is to compare the base excess (BE) values-an indicator of metabolic changes-in two groups of patients at Santo Tomás Hospital: those with severe preeclampsia and healthy, pregnant individuals. Researchers will measure these values using an arterial blood gas test before delivery or surgery. This is a prospective cohort study. The researchers will analyze various blood gas parameters, including pH, lactate, and BE, and then correlate the BE values with clinical variables and negative maternal outcomes. The expected outcome is that a abnormal BE values will be linked to a greater severity of preeclampsia. If this association is confirmed, BE could serve as an additional marker for predicting the severity of the condition and may lay the groundwork for future research on diagnostic and therapeutic standards based on blood gas analysis.
