Passive drains rely on gravity or capillary action to remove fluid, whereas active drains rely on a suction/vacuum force, whether that be through connection to wall suction, a portable suction device, or a bulb that has been squeezed to create a vacuum. Open drains are commonly used for superficial wounds and drain into dressings or a stoma bag.
The wound can be allowed to close by secondary intention. Alternatively, if the infection is cleared and healthy granulation tissue is evident at the base of the wound, the edges of the incision may be reapproximated, such as by using butterfly stitches , staples or sutures .
Prior to the development of the Eloesser flap in the 1930s, the main surgical treatments for chronic tuberculous empyema were an open thoracotomy or chest tube drainage. In his original published description of the procedure, Dr. Eloesser wrote that he felt that those options were "unsatisfactory" as he felt they led to secondary infection and ...
Maggot therapy (also known as larval therapy) is a type of biotherapy involving the introduction of live, disinfected maggots (fly larvae) into non-healing skin and soft-tissue wounds of a human or other animal for the purpose of cleaning out the necrotic (dead) tissue within a wound (debridement), and disinfection.
Diagnosis of a skin abscess is usually made based on what it looks like and is confirmed by cutting it open. [1] Ultrasound imaging may be useful in cases in which the diagnosis is not clear. [1] In abscesses around the anus, computer tomography (CT) may be important to look for deeper infection. [3]
The cord provides a path that allows the fistula to drain continuously while it is healing, rather than allowing the exterior of the wound to close over. Keeping the fistula tract open can help prevent the trapping of pus or other infectious material in the wound. The procedure was mentioned by Hippocrates.
Infection will complicate healing of surgical wounds and is commonly observed. [ 2 ] [ 4 ] Most infections are present within the first 30 days after surgery. [ 5 ] Surgical wounds can become infected by bacteria, regardless if the bacteria is already present on the patient's skin or if the bacteria is spread to the patient due to contact with ...
Negative-pressure wound therapy (NPWT), also known as a vacuum assisted closure (VAC), is a therapeutic technique using a suction pump, tubing, and a dressing to remove excess exudate and promote healing in acute or chronic wounds and second- and third-degree burns. The therapy involves the controlled application of sub-atmospheric pressure to ...
