ANTONIO, Viruez Soto  and  OSCAR, Vera Carrasco. Acid-base status in critical care obstetrics at altitude. Cuad. - Hosp. Clín. [online]. 2023, vol.64, n.2, pp.21-26. ISSN 1562-6776.

Abstract Objective: To describe the acid base status in critically ill obstetric patients at very high altitude, at the time of admission to the Intensive Care Unit. Methodology: Retrospective descriptive study. All obstetric patients admitted to the Adult Intensive Care Unit of the Hospital del Norte in the city of El Alto, La Paz at 4150 meters above sea level, in the period January 2019-January 2022, are included. Results: 79 patients were admitted, with a mean age of 29 years (standard deviation 8.06 years), 52 cases (66%) due to severe preeclampsia, 14 cases (18%) due to obstetric hemorrhage, 8 cases (10%) due to obstetric sepsis. and 5 (6%) due to various diagnoses such as supraventricular tachycardia and poisoning, there were 8 deceased patients (10% mortality), highlighting obstetric sepsis with the highest death rate and longest hospital stay. Discussion: The physiological changes during pregnancy make her a risk patient, identifying the apparent and abbreviated strong ion difference as possible prognostic factors in the critically ill obstetric patient

Keywords : Acid-base state; critical obstetrics; high altitude.
