Fluid Analysis:- Part 1 – Pleural, Pericardial, and ascites, Difference of Transudate and Exudate
Definition of Fluids in various cavities of the body:
- The fluid is secreted by the serous membranes lining the peritoneum, pleural and pericardial cavities.
- Literally, serous fluid means resembling serum.
- This serous fluid is found in the pleural, peritoneal, and pericardial cavities, which will lubricate the opposing parietal and visceral membrane surfaces.
- Inflammation or infection affecting the cavities causes fluid to accumulate.
- Serous fluid is the ultrafiltrate of the plasma.
- The fluid formation depends upon the following:
- Hydrostatic pressure.
- Capillaries permeability.
- Colloid osmotic pressure.
- Lymphatic drainage.
Types of body fluid found are:
- The pericardial cavity around the heart contains the fluid, and the aspiration of the pericardial fluid is called pericardiocentesis.
- Peritoneal or ascitic fluid is found in the abdomen. This is the effusion and accumulation of serous fluid in the abdominal cavity. Its aspiration is called paracentesis.
- Pleural cavity fluid was found in the chest. And aspiration is called thoracentesis.
- Gastric fluid is 1000 to 3000 mL/day.
- Bile is 300 to 1000 mL/day.
- Saliva is 500 to 1500 mL/day.
- Pancreatic fluid is 1000 to 1500 mL/day.
- Small intestinal fluid is 1000 to 2000 mL/day.
- Urine output is 500 to 1500 mL/day.
- Insensible loss through skin and lungs is 600 to 1000 mL/day.
