VIRUEZ SOTO, Antonio et al. Lactate clearance and mortality in high altitude residents with severe trauma. Rev. Cuerpo Med. HNAAA [online]. 2021, vol.14, n.3, pp.291-296. Epub 26-Nov-2021. ISSN 2225-5109. http://dx.doi.org/10.35434/rcmhnaaa.2021.143.1247.
Introduction:
Several studies report that lactate clearance is associated with mortality in critically ill patients.
Objectives:
To describe the relationship between lactate clearance and lactate normalization with mortality in high-altitude resident patients with severe trauma. To know the mortality of patients with severe trauma at altitude. Know the injury distribution of severe trauma at altitude.
Methods:
Epidemiological, observational, analytical, cohort, retrospective study, carried out in an intensive care unit located at 4,150 "masl" in patients admitted for severe trauma. The inclusion criteria were: a) Diagnosis of severe trauma. b) Injury severity score greater than 16. c) Presence of the result of the lactate analysis at admission and at 6 hours in the ICU and d) Resident of the altitude since the age of 12. Patients with incomplete and unreadable medical records were excluded.
Results:
160 patients were included, mortality of 15%, 65% of the injuries were due to severe brain trauma. In the group of survivors (136), lactate clearance was 52.27% and in the group of deceased it was 21.38%. In relation to normalization (lactate <2 mmol / L), the group of survivors had 47% compared to 1% of the deceased.
Conclusions:
Lactate clearance and lactate normalization at 6 hours are protective factors to decrease mortality from severe trauma. Mortality from severe trauma is 15%. Severe head trauma was the most frequent injury.
