Abstract
Introduction: Trauma is a public health problem in Colombia and is the first cause of death in young people with an incidence rate of 331.99 cases per 100 000 inhabitants, of which approximately 30% die in the intensive care unit. These patients according to their severity will require stabilization of vital signs and close monitoring which includes the acid-base status. Objetive: To establish the relationship between outcome and variables of acid-base equilibrium of those patients diagnosed with trauma in the intensive care unit of the Hospital Universitario San Jorge in Pereira, Colombia. Materials and Methods: A prospective cohort study in type was performed on the intensive care unit with general trauma patients who were taking blood gases on admission to the unit and were monitored over time until discharge. Results: The population of the study were 38 patients with trauma, 68.4% were men. Average age was 35±19 years and 18.4% of patients admitted died. The univariate analysis was found individual relationship with outcome and variables such as sodium, arterial oxygen saturation, alveolar oxygen pressure and APACHE II score. In the Cox regression model it was found a relationship between outcome and variables such as alveolar oxygen pressure, pressure oxygen pressure, heart rate and arterial-alveolar ratio of oxygen. Conclusion: Variables found that alveolar oxygen pressure, arterial oxygen pressure, heart rate and arterial-alveolar oxygen ratio of arterial blood gas analysis, correlate with survival of patients in critical condition. An invitation to use this paraclinical test is done. MÉD UIS. 2015;28(3):273-80.
