Abstract:

Introduction and Purpose: This study studies the effects of blood gas analysis on mortality. This method can contribute to the reduction of mortality rates in intensive care and emergency services. Method and Requirements: Work data were obtained and analyzed backward from patients brought to the Emergency Service of Haydarpaşa sample Education and Research Hospital between January 2016-January 2017. The study included 274 patients and the patient data was collected from the first blood gas records in emergency applications. Discoveries: Our study has shown us that laktate, basal deficiency and bikarbonate levels may be associated with mortality. The statistical analysis for lactate had the values of 4.64±4.696 mEq/L in the non-resistance group and was significant in terms of mortality (p=0,000). In the ROC analysis of lactate, the area under the curve was determined at 0.725 . When the laktate is above 1.5 mEq/L, it has a 76% sensitivity and a 54% individuality. In the surviving group (medium±SS), the values of -5.57±9.852 mmol/L for the base gap were found meaningful in terms of mortality (p=0,000). The area under the curve, for the base gap, was found at 0.726 ROC analysis at -2.5 mmol/L. This value was found to have 63% sensitivity and 74.7% individuality. For bikarbonate (medium±SS) 19.63±7.725 mmol/L range values were found meaningful as the predictor of mortality (p<0.05). Our study observed a mortality of 62% in the basal values of -2 mmol/L and below for the basal gap and found that the mortality was a meaningful predictor. Other parameters (pH, PCO2, PaO2) were not found meaningful in predicting mortality (p>0.05). CONTRACT AND RESULT: The data obtained in our study has determined that the laktate, bikarbonate and basic gap values may be the predictor of mortality.
