Pulmonary function changes in cirrhosis of the liver

Area of Science:

• Pulmonology
• Hepatology
• Internal Medicine

Background:

• Cirrhosis of the liver is a severe condition often leading to various complications.
• Ascites, a common complication of cirrhosis, may impact respiratory function.
• Understanding the pulmonary effects of cirrhosis is crucial for comprehensive patient management.

Purpose of the Study:

• To investigate and quantify the presence and nature of ventilatory disorders in cirrhotic patients with ascites.
• To compare pulmonary function test results between cirrhotic patients with ascites and healthy controls.

Main Methods:

• Pulmonary function tests were conducted on 21 patients diagnosed with liver cirrhosis and ascites.
• A control group of 50 healthy individuals was included for comparative analysis.
• Key pulmonary parameters measured included vital capacity, maximum voluntary ventilation, functional residual capacity, total lung capacity, and forced expiratory volume.

Main Results:

• Cirrhotic patients exhibited significantly lower vital capacity (93.67% vs. 102.47%, p<0.05) and total lung capacity (4675 ml vs. 5791.56 ml, p<0.01) compared to controls.
• Maximum voluntary ventilation was markedly reduced in the cirrhotic group (89.33% vs. 127.48%, p<0.001).
• Functional residual capacity (2362.19 ml vs. 3085.1 ml, p<0.01) and forced expiratory volume (70.1% vs. 77.74%, p<0.05) were also significantly diminished in patients with cirrhosis.

Conclusions:

• The study demonstrates prominent restrictive ventilatory disorders in cirrhotic patients with ascites.
• Obstructive ventilatory disorders were also identified in this patient group.
• These findings highlight the significant impact of liver cirrhosis on respiratory system function.
