Suction drainage

Suction drainage - long active (with the creation of vacuum suction content from cavities and hollow organs: chest and abdominal cavity, small pelvis, stomach, intestines, bladder, etc.
installation for suction drainageSuction drainage may be water-jet pump, which is attached to the faucet (Fig.1), and the way Subbotina - moving vertically, one of the two communicating vessels. The vacuum in this case is created due to the leakage of fluid from the top of the vessel (connected to the receiver at the bottom. In surgical practice is widely applied suction from the stomach of a thin probe is inserted through the nose and connected to the suction of the three bottles (Fig. 2).
Depending on the conditions and goals of the suction drainage apply various vacuum (low pressure, the negative pressure in millimeters of mercury).
The method of constant suction gastro-intestinal contentsFor the evacuation of fluid and gas in the pleural cavity in a vessel sink, and consequently in the pleural cavity, create a vacuum operation from 5 to 50 mm RT. Art. this vacuum exudate comes thin stream or big drops.
A large gathering of the exudate are advised to evacuate simultaneously (syringe) not more than 500 ml of the liquid, and the rest to remove by means of suction drainage.
In the treatment of chronic ambiem used vacuum operation from 5 to 200 mm RT. Art., increasing the vacuum slowly. In this case, the fluid enters the vessel separate drops. Termination of its receipt serves as a signal of increasing the vacuum to the emergence of a new portion of exudate.
When the suction drainage after operations on the lungs vacuum mode start with 10-15 mm RT. century and gradually increase up to 300 mm RT. Art.
The mechanism of elimination of prirastajte gastrointestinal tract (enteroparesis after operations on the organs of abdominal cavity, peritonitis, dynamic obstruction of the bowel) in the suction drainage probe inserted through the nose into the stomach, is as follows: after the evacuation of the stomach to create evacuated space, making periodically through relaxing the porter content from pererastayut upper intestine reverse current enters the stomach and was evacuated from him.
The most effective evacuation of the contents of the gastrointestinal tract through a thin probe by source of constant negative pressure. In this case, the probe is introduced into the stomach, and for long-term extraction of the contents of the intestine (bowel intubation) and held later in the intestine that connects to the system of three large bottles, located on different levels (Fig. 2)where due to the flowing fluid continuously supported the negative pressure. Water, flowing from the bottle 1 bottle 2. creates negative pressure in the bottle 3, where the probe is aspiration of gastric-intestinal contents. When the suction drainage in this way you can judge about the number and nature of sucked content. Probe hold until then. until you restore the normal function of the gastrointestinal tract, which will indicate the emergence of a net content from the stomach and clear of intestinal peristalsis.

Suction drainage - long active (with the creation of vacuum suction content and detachable from a variety of cavities and hollow organs: chest and abdominal cavity, small pelvis, stomach, intestines, bladder, etc.
Suction drainage can be carried out by the gravity of the liquid column and water-jet pump, which is connected to the faucet. However, use of the pump often there is interference - shake and adhesion of trunk pipes made of plastic or rubber, which is drawn in the contents. More acceptable is the way M. S. Subbotin - move (but vertical) one of the two communicating vessels; the vacuum created by the flow of liquid from the top (connected to the receiver) of the vessel at the bottom. In surgery the most widely used evacuation of the stomach by means of three bottles.
Suction drainage, in addition to medical treatment, used in the diagnosis of bronchopleural fistula. This aspirator (suction station construction NIIHAU) disconnect from the receiver to the maximum rarefaction. The fall of underpressure in the receiver indicates the presence of the fistula, and the rate of decrease of its size. With the help of the Alexander Palace is possible to evacuate the exudate or gas from the pleural cavity, to spread light in the treatment of chronic ambiem and busy pneumothorax. For the same purposes of the Alexander Palace is used as the final stage of surgical intervention after pleurectomy, decortication and various types of lung resection. Depending on the conditions and goals of the suction drainage apply various vacuum mode.
1. For evacuation of fluid and gas in the pleural cavity in a vessel sink, and consequently, in the pleural cavity create a vacuum operation from 5 to 50 mm RT. Art. this vacuum exudate comes in the form of a trickle or a large drops. This allows you to avoid unpleasant subjective sensations of the patient (flank pain, shortness of breath and so on). A large gathering of the exudate are advised to evacuate not more than 500 ml of the liquid simultaneously, but the rest delete by A. D.
2. Unfolding rigid light in the treatment of chronic ambiem used vacuum operation from 5 to 200 mm RT. Art. the vacuum increase slowly to power, due to exhaustion, not far exceeded the power of the resistance offered rigid pleura. In this case, the fluid enters the vessel separate drops and termination of its receipt serves as a signal to increase the vacuum to the emergence of a new portion of exudate.
3. After operations on the lungs vacuum mode start with 10-15 mm RT. senior smoothly and gradually increase up to 300 mm RT. Art.
The empyema can be drained from several patients with special suction stations; the degree of rarefaction of air for each patient is regulated but indications.
The mechanism of removing stretch of the gastrointestinal tract using the Alexander Palace tube inserted into stomach, is as follows: after the evacuation of the accumulated congestive content in the stomach creates evacuated space, making periodically through relaxing the porter congestive content pererastayut intestine reverse current enters the stomach, and he was evacuated from it (see bowel Obstruction).
The most rational and effective evacuation of the contents of the gastrointestinal tract through a thin probe is carried out by means of a source of constant negative pressure (M. S. Subbotin). This probe is introduced into the stomach and then in the intestines, is connected to system of three large bottles, located on different levels. Suction drainage bowel - see bowel Intubation.
