In this context, the most important assessment of the pleural fluid is the percentage by volume that is taken up by red blood cells (the hematocrit) A hemothorax is defined as having a hematocrit of at least 50% [6] of that found in the affected person's blood, although the hematocrit of a chronic hemothorax may be between 25 and 50% if ...
Focused assessment with sonography in trauma (commonly abbreviated as FAST) is a rapid bedside ultrasound examination performed by surgeons, emergency physicians, and paramedics as a screening test for blood around the heart (pericardial effusion) or abdominal organs (hemoperitoneum) after trauma.
Hemopneumothorax, or haemopneumothorax, is the condition of having both air (pneumothorax) and blood in the chest cavity. A hemothorax, pneumothorax, or the combination of both can occur due to an injury to the lung or chest.
Massive right sided pleural effusion later confirmed to be a hemothorax. Hemothorax, or accumulation of blood in the pleural space, can result from trauma or surgical procedures in the chest. This accumulation of blood can grow large enough to compress the lung and push away other structures in the chest, thus causing a mediastinal shift. [6]
Red blood cell counts are elevated in cases of bloody effusions (for example after heart surgery or hemothorax from incomplete evacuation of blood). Amylase levels are elevated in cases of esophageal rupture, pancreatic pleural effusion, or cancer. Glucose is decreased with cancer, bacterial infections, or rheumatoid pleuritis.
Hepatic hydrothorax is a rare form of pleural effusion that occurs in people with liver cirrhosis.It is defined as an effusion of over 500 mL in people with liver cirrhosis that is not caused by heart, lung, or pleural disease.
Considering that the total volume of the tracheal and bronchial lumen is about 150 cc, [28] [29] it may be reasonable to define massive hemoptysis as 200 ml, which is a little more than 150 ml, in terms of setting the threshold for fatal hemoptysis. More than 400ml/day is not adequate for screening purposes.
Initial management consists of immediate blood transfusion if the patient is in hemorrhagic shock. Classically, hemoperitoneum was an indication for emergency surgery to locate the source of bleeding and also to recover spilled blood from the peritoneal cavity and to use it for auto-transfusion if it has not been contaminated by ruptured bowel contents.
