ABSTRACT:
Introduction: The Maternal Mortality Rate estimate for 2017 shows that, on average, 211 women died for every 100,000 live births
globally, with a rate of 415 in low-resource countries. Primary postpartum hemorrhage is defined as blood loss from the genital tract
greater than 500 mL after birth or 1000 mL at Caesarean section within the first 24 hours after birth.
Material and Method: A comparative study was carried out in 21 patients with a history of an obstetric hemorrhagic shock to
assess the correlation of the observational vs. arterial blood gases (lactate and DB during a period from March 2022 to January 2023.
Statistical analysis: Descriptive and parametric statistics were used for the variables included.
Results: Twenty-One patients were studied, patients with obstetric hemorrhage (100%) whose data are presented in Table 1. 7
patients (33%) were transfused with less than 1000 mL and 14 patients (66.6%) with more than 1000 mL, the range was 2500 mL,
the minimum transfusion of 500 mL and the maximum of 3000 mL, a total of 24,700 mL were transfused in these patients, there
were no maternal deaths. Conclusions: The use of blood gases is recommended in all patients with acute obstetric hemorrhage.
Discussion: The registry of Intraoperative blood loss plays a central role in the daily routine of doctors. Therefore, for the safety
of the patient, we should aim for the highest possible measurement accuracy.
Conclusion: Routine use of blood gases is recommended for patients with acute obstetric hemorrhage.
