Background: Hepatopulmonary syndrome is characterized by clinical triad of chronic liver disease, hypoxemia and intrapulmonary vascular dilatation. Routine screening of hypoxemia is not performed in all patients with liver cirrhosis. Blood gas analysis is difficult, fairly invasive, expensive and requires special skills; thus, another alternative is required for detection of hypoxemia including pulse oximetry (SpO2).
Objective: To analyze the comparison of SpO2 pulse oximetry with SaO2
to detect hypoxemia in patients with liver cirrhosis.
Methods: Subjects were grouped into the severity based on Child Pugh score A, B, and C. The subjects were examined for blood gas analysis and pulse oximetry. Data were analyzed using Kruskal Wallis test and Wilcoxon test (p <0.05).
Results: The highest cause of liver cirrhosis was hepatitis B of 19 patients (57.6%) and the severity based on Child Pugh B as many as 18 patients (54.5%). The proportion of hypoxemia (<80 mmHg) was 15%. The comparison of SpO2 and SaO2 in LC patients showed no significant difference between SPO2 and SaO2 (child B, p = 0.15 and child C, p = 0.07).
Conclusion: There was no significant difference between SpO2 (pulse oximetry) and SaO2 (Blood Gas Analysis) in liver cirroshis patients.
