RELACIóN DEL APORTE DE OXíGENO Y LA SUPERVIVENCIA DEL PACIENTE CON SHOCK EN UCI

introduction: to establish the repercussion between survival of the critically ill patient-diagnosed with shock (all kinds of etiology)-and the diagnosis of acid/ base balance of the blood gas analysis. methods: prospective cohort study. setting: one general intensive care unit. patients: ppatients diagnosed with shock to whom blood gas analysis was made. variables of interest: outcome defined as survival of the patients in function of time. moreover, some variables were monitored such as acid/base balance, respiratory function, ventilatory function and blood electrolytes. they were all monitored in function of time. results: the cox regression model showed that male patients diagnosed with shock had 2.78 times greater risk of dying compared to women. fio2 and thbc variables work as mortality predictors while pao2, pco2, and po2 variables are protective factors for mortality. conclusion: early diagnostic in acid/base balance of patients with shock-arriving at the intensive care unit-and immediate therapeutic intervention of those variables part of tissue oxygen delivery (such as pao2, fio2, thbc, pco2, and po2) will favorably change the prognostic and survival of the patients.
