Abstract :

Introduction: Most serious diseases involve variable degree of acid–base disorder requiring rapid identification and treatment to achieve improved survival. Objectives: Identify differences in Arterial blood gas (ABG) parameters in patients visiting the Medical ICU and relate initial ABG results to mortality. Methods: 300 patients admitted to the MICU irrespective of underlying pathology and undergoing complete ABG analysis were included and divided into groups of survivors and non survivors depending upon mortality within 7 days of admission. Possible differences in ABG parameters were then compared between survivors and non–survivors. Results: Dividing the patients on the basis of reference range, acidosis (pH<7.35), hypercapnia (pCO2>45mHg), hyperoxia (pO2 >99%), hyperkalemia (>4.5 mmol/L), hyperglycaemia (>105mg/dL), hyperlactataemia (>1.6 mmol/L), decreased bicarbonate (<22.0mmol/L and hypochloremia (<98.0mmol/L) were related to high mortality. Conclusion: ABG analysis in patients presenting to the ICU can help in predicting adverse outcome.
