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

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

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.

Complete drainage is crucial and if percutaneous drainage is inadequate either laparoscopic drainage or laparotomy is essential to achieve optimal drainage, as persistent intra-abdominal sepsis is the most serious immediate threat to life.
In a similar case of recurrent, solitary Page kidney, (4) initial conservative radiologic management via percutaneous drainage of the subcapsular renal hematoma (along with sclerosing attempts) failed, leading to eventual definitive management requiring embolization.
Therefore, recently, for patients suspected of having appendicitis associated with an abscess in the periappendix, instead of traditional emergency surgery, the trend has been to perform conservative treatments, for example, ultrasound-guided percutaneous drainage and antibiotic treatments first and subsequently to perform an interval appendectomy after a certain time: nonetheless, until now, standard treatment protocols have not been established, so this issue is still controversial.
