drainage

 [drān´ij]
systematic withdrawal of fluids and discharges from a wound, sore, or cavity.
capillary drainage that effected by strands of hair, surgical gut, spun glass, or other material of small caliber which acts by capillary attraction.
closed drainage airtight or water-tight drainage of a cavity so that air or contaminants cannot enter; for example, drainage of an empyema cavity carried out by means of an intercostal drainage tube passing into an airtight receiving vessel.
open drainage drainage of a cavity through an opening in the chest wall into which one or more drainage tubes are inserted, the opening not being sealed against the entrance of outside air.
percutaneous drainage drainage of an abscess or collection of fluid by means of a catheter inserted through the skin and positioned under the guidance of computed tomography or ultrasonography.
postural drainage see postural drainage.
tidal drainage drainage of the urinary bladder by an apparatus that alternately fills the bladder to a predetermined pressure and empties it by a combination of siphonage and gravity flow.

drainage

/drain·age/ (drān´ij) systematic withdrawal of fluids and discharges from a wound, sore, or cavity.
capillary drainage  that effected by strands of hair, surgical gut, spun glass, or other material of small caliber which acts by capillary attraction.
closed drainage  drainage of an empyema cavity carried out with protection against the entrance of outside air into the pleural cavity.
manual lymph drainage  the application of light rhythmic strokes, similar to those of effleurage, in the direction of the heart to increase the drainage of lymph from the involved structures.
open drainage  drainage of an empyema cavity through an opening in the chest wall into which one or more rubber drainage tubes are inserted, the opening not being sealed against the entrance of outside air.
postural drainage  therapeutic drainage in bronchiectasis and lung abscess by placing the patient head downward so that the trachea will be inclined below the affected area.
through drainage  that achieved by passing a perforated tube through the cavity, so that irrigation may be effected by injecting fluid into one aperture and letting it escape out of another.

drainage

(drā′nĭj)
n.
Medicine The removal of fluid or purulent material from a wound or body cavity.

drainage

[drā′nij]
Etymology: AS, drachen, teardrop
the removal of fluids from a body cavity, wound, or other source of discharge by one or more methods. Closed drainage is a system of tubing and other apparatus attached to the body to remove fluid in an airtight circuit that prevents environmental contaminants from entering the wound or cavity. Continuous bladder irrigation is drainage in which a body area is washed out by alternately flooding and then emptying it with the aid of gravity, a technique that may be used in treating a urinary bladder disorder. Open drainage is drainage in which discharge passes through an open-ended tube into a receptacle. Suction drainage uses a pump or other mechanical device to assist in extracting a fluid. See also postural drainage,tidal drainage.

Surgery
1. The withdrawal of fluids from a body cavity or region.
2. Discharge, see there. See Percutaneous transhepatic biliary.

drain·age

(drān'ăj)
Continuous flow or withdrawal of fluids from a wound or other cavity.

drainage

(dran'ij)
The flow or withdrawal of fluids, such as blood, infused saline, pus, and collected debris, from a cavity, organ, surgical site, or wound. See: autodrainage; drain

active drainage

Drainage in which negative pressure is maintained in the drainage tube. It is used in treating pneumothorax and in certain types of drains or catheters in the intestinal tract, body cavity, or surgical wound. Synonym: negative pressure drainage; suction drainage. See: Wound Drainage Systems: Negative Pressure

autogenic drainage

A diaphragmatic breathing pattern used by patients with respiratory illnesses (e.g., cystic fibrosis, bronchiectasis) to clear the lungs of mucus and other secretions. Various techniques are used, all of which combine positive reinforcement of deep breathing and voluntary cough suppression for as long as possible before evacuating the airways of mucus.

capillary drainage

Drainage by means of capillary attraction.

chest drainage

Placement of a drainage tube in the chest cavity, usually in the pleural space. The tube is used to drain air, fluid, or blood from the pleural space so the compressed and collapsed lung can expand. The tube is connected to a system that produces suction. This helps to remove the material from the pleural space and also prevents air from being sucked into the space.

closed drainage

Drainage of a wound or body space into a self-contained, sealed collecting system.

closed sterile drainage

A sterile tube draining a body site, such as the abdominal cavity or pleural space, that is designed to prevent the entry of air and bacteria into the tubing or the area being drained.

lymphatic drainage

Manual lymphatic drainage.

manual lymphatic drainage

Abbreviation: MLD
Gentle massage techniques used to correct localized lymphedema, e.g., in patients who have swelling of an arm after mastectomy with lymph node dissection. The therapist assists lymphatic flow from the extremity toward the heart. Synonym: lymphatic drainage

negative pressure drainage

Active drainage.

open drainage

Drainage of a wound or body cavity using absorbent materials or catheters that are in contact with the ambient conditions outside the patient.

postural drainage

A passive airway clearance technique in which patients are positioned so that gravity will assist the removal of secretions from specific lobes of the lung, bronchi, or lung cavities. It can be used for patients with pneumonia, chronic bronchitis, cystic fibrosis, bronchiectasis, inhaled foreign bodies, before surgery for lobectomy, or in any patient having difficulty with retained secretions. A side effect of the treatment in some patients is gastroesophageal reflux. See: illustration

Patient care

Physical tolerance to the procedure is evaluated. The respiratory therapist teaches and assists the patient in the procedure, as ordered, by positioning the patient for effective drainage of the affected lung region(s). The patient is encouraged to remove secretions with an effective cough. To decrease the risk of aspiration, the patient should not perform the procedure after meals. Chest vibration and percussion are often performed at the same time to assist movement of retained secretions in the lung.

suction drainage

Active drainage.

through-and-through drainage

Irrigation and drainage of a cavity or an organ such as the bladder by placing two perforated tubes, drains, or catheters in the area. A solution is instilled through one catheter, and the other tube collects the returned fluid actively (by suction) or passively.

tidal drainage

A method, controlled mechanically, of filling the bladder with solution by gravity and periodically emptying the bladder with a catheter. It is usually used when the patient lacks bladder control as in injuries or lesions of the spinal cord.

capillary drainage
that effected by strands of hair, catgut, spun glass, or other material of small caliber which acts by capillary attraction.
closed drainage

peritoneal drainage
drainage of the peritoneum; limited by the rapid formation of adhesions and can only be accomplished with lavage or through an open cavity.
suction drainage
a source of continuous or intermittent negative pressure is used to maintain drainage in various sites, particularly negative pressure in the pleural cavity. A syringe and valve, one-way valve, vacuum tube or underwater drain can be used for this purpose.
