[The interrelation between lung function disorders and deviations in the blood coagulation system]

Area of Science:

• Pulmonary Medicine
• Hematology
• Critical Care Medicine

Background:

• Pneumonia is a common complication in patients with abdominal hemorrhage.
• Alterations in blood coagulation are frequently observed in critical illness.
• The relationship between lung function and coagulation disorders needs further elucidation.

Purpose of the Study:

• To investigate the interrelationship between lung function disorders and blood coagulation system deviations.
• To analyze coagulation parameters in mixed venous and arterial blood of patients post-abdominal hemorrhage.
• To determine the primary drivers of hemostasiologic changes in this patient cohort.

Main Methods:

• Conducted 102 complex studies on blood coagulation in mixed venous blood.
• Performed 36 studies on arterial blood coagulation in patients after abdominal hemorrhage.
• Analyzed arteriovenous differences for blood coagulation parameters.

Main Results:

• Patients with pneumonia exhibited disseminated intravascular blood coagulation (DIC) or its aggravation.
• The observed DIC typically presented as a hypocoagulable type.
• Platelet aggregation activity was notably increased in these patients.
• Analysis of arteriovenous differences indicated inflammatory processes as the main cause of hemostasiologic changes.

Conclusions:

• Pneumonia in the context of abdominal hemorrhage is associated with DIC.
• The inflammatory process, rather than primary lung function failure, is the main driver of coagulation abnormalities.
• Increased platelet aggregation is a key feature of the observed coagulation derangements.
