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.

closed drainage

drainage of an empyema cavity carried out with protection against the entrance of outside air into the pleural cavity.

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.

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.
