A STUDY ON CORRELATION OF ACIDEMIA WITH PATIENTS 30 DAYS MORTALITY THOSE PRESENTING TO EMERGENCY DEPARTMENT OF A TERTIARY HOSPITAL

Abstract

Introduction: Acidosis is a process causing increased acidity in the blood and other body tissues (i.e., an increase in hydrogen ion concentration). If not further qualied, it usually refers to acidity of the blood plasma Acidemia is said to occur when arterial pH falls below 7.35 , while its counterpart (alkalemia) occurs at a pH over 7.45. Arterial blood gas analysis and other tests are required to separate the main causes.Aims: To nd out correlation between different grades of Acidemia with 30 day mortality of patient diagnosed as academic in emergency department Materials and method: This was a single center observational, retrospective cohort study from tertiary care hospital in Kolkata, India from January 2021 – January – 2022. All Patients were presenting with signs of Acidemia in Emergency Department. Age >18 years, Blood gas analysis, Done in ED and pH ≤ 7.34 were included in this study. Result: In mortality, 33(32.4%) patients were in <7.0 PH group, 31(30.4%) patients were in 7.0-7.10 PH group, 23 (22.5%) patients were in 7.11-7.20 PH group and 15 (14.7%) patients were in 7.21-7.34 PH group. Association of PH group with Mortality was statistically signicant (p<0.0001). In without Mortality, the mean Age (mean± s.d.) of patients was 57.0268 ±9.2811. In with Mortality, the mean Age (mean± s.d.) of patients was 56.2549±9.0758. Distribution of mean Age with Mortality was not statistically signicant (p=0.4506). In without Mortality, the mean PH (mean± s.d.) of patients was 7.1898 ±.1189. In with Mortality, the mean PH (mean± s.d.) of patients was 6.9708 ±.2907. Distribution of mean PH with Mortality was statistically signicant (p<0.0001). In without Mortality, the mean Hospital Stay (mean± s.d.) of patients was 14.1512 ±5.5302. In with Mortality, the mean Hospital Stay (mean± s.d.) of patients was 7.4804 ±6.1010. Distribution of mean Hospital Stay with Mortality was statistically signicant (p<0.0001). Conclusion: Patients presenting in emergency with low PH (acidemia) require immediate management and hospitalization for better outcome.
