Thoracentesis and paracentesis are medical-surgical procedures, adopted for therapeutic and diagnostic purposes, with the aim of verifying the cause of a possible accumulation of thoracic – abdominal fluid; This is taken and analyzed in case of thoracentesis, from the pleural cavity (the fluid is called pleural exudate) and in case of paracentesis (or peritoneocentesis), from the peritoneal cavity (ascitic fluid).

The pleural cavity is the space bounded by the parietal and visceral pleural leaflet, in which the negative pressure is formed that allows the lungs to expand their volume during inspiration. The peritoneal cavity is also defined as an anatomical “space”, however more specifically, at the abdominal level, it is covered by a thin serous membrane and distinct in parietal and visceral peritoneum.

thoracentesis-and-paracentesis

The membranes that cover these regions of our body pour a limited amount of liquid, which in correct quantities, is essential for the mutual sliding of the walls of the cavities (thoracic or abdominal) and those membranes that line the organs; while, when there is an accumulation of it in quantities higher than normal, at the thoracic level we speak of pleural effusion, and at the abdominal level of ascites.

This phenomenon can occur due to several factors including:

1. the formation of a tumor that affects the lining membrane or the organ lined by it

2. the development of inflammatory diseases of the membranes

3. the absence of adequate proteins that are normally present within the plasma, with the function of limiting the extent of such effusions

4. etc…

Ascites and pleural effusion can lead to serious consequences both on our organs, which are forced due to effusion and therefore subjected to pressure exerted by excess fluid, which can hinder breathing or cause pain; and on our body tissues, which undergo an important subtraction of liquids, as evidently generate serious systemic reverberations.

The procedures of thoracentesis and paracentesis are acts of medical competence and are conducted under local anesthesia and under ultrasound guidance, with the introduction of a very thin needle, in the chest or abdomen, connected to a drainage tube that has the other end connected to a collection vessel.

The collection vessel can be, for example:

– a drainage bag

– a syringe, in case you want to carry out a laboratory analysis and then the procedure is for diagnostic purposes

– other sterile containers (glass bottle, etc…)

Infra, in this context, can contribute indirectly through the supply of one of the types indicated for collection, namely the drainage / drainage bag in PVC; This, in fact, is made of non-toxic material, with molded graduation, latex free and in various capacities.

Evidently the shape and finishes of the bag must comply with the particular request of the application in which it is inserted. However, in principle it is composed of two tubes at the lower ends, a longer one to be able to connect, for example, to a syringe / needle to drain the liquid present in the cavity and a shorter one, which can be equipped for example with a drain tap, such as Push / Pull (simplified version) or T, which represent more valuable versions.

Given the seriousness of the results of the aforementioned liquids, it is evident how basic the treatments described are to promptly correct the balance and prevent the damage mentioned. In this regard, each component involved must have performance characteristics that are adequate, reliable and safe. The Infra bag can effectively meet all these requirements.
