Bronchoalveolar Lavage
Bronchoalveolar lavage (BAL), also known as bronchoalveolar washing, is a diagnostic method of the lower respiratory system in which a bronchoscope is passed through the mouth or nose into an appropriate airway in the lungs, with a measured amount of fluid introduced and then collected for examination. This method is typically performed to diagnose pathogenic infections of the lower respiratory airways (e.g. pneumonia and COVID-19), though it also has been shown to have utility in diagnosing interstitial lung disease. Bronchoalveolar lavage can be a more sensitive method of detection than nasal swabs in respiratory molecular diagnostics, as has been the case with SARS-CoV-2 where bronchoalveolar lavage samples detect copies of viral RNA after negative nasal swab testing. In particular, bronchoalveolar lavage is commonly used to diagnose infections in people with immune system problems, pneumonia in people on ventilators, and acute respiratory distress syndrome (ARDS). It is th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whole Lung Lavage
Whole lung lavage (WLL), also called lung washing, is a medical procedure in which the patient's lungs are washed with Saline (medicine), saline (salt water) by filling and draining repeatedly. It is used to treat pulmonary alveolar proteinosis, in which excess lung surfactant proteins prevent the patient from breathing. Some sources consider it a variation of bronchoalveolar lavage. WLL has been experimentally used for silicosis, other forms of mineral inhalation, and accidental inhalation of radioactive dust. It appears to effectively remove these foreign particles. WLL treatments may slow down the lung function decline of miners with pneumoconiosis. Medical uses Whole lung lavage (WLL) is primarily used for treating conditions like pulmonary alveolar proteinosis (Pulmonary alveolar proteinosis, PAP), where it helps remove accumulated surfactant proteins from the lungs. However, its application extends to other respiratory conditions, including Acute respiratory distress synd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ductal Lavage
Ductal lavage is a screening method used in at-risk women for breast cancer detection. In this method, cells are collected from milk ducts in the breast. The procedure involves inserting a catheter (tube) into the nipple, which releases a small amount of salt water into the duct. The water picks up breast cells and the entire fluid is then retrieved and sent to be examined for cells, which are checked under a microscope. Apart from clinical breast examination and mammography, ductal lavage can also be used to detect breast cancer. Procedure Ductal lavage is a non-invasive screening procedure. It is used to detect precancerous and cancerous cells in the breast ducts. It is a safe and well-tolerated procedure. Some doctors might apply anesthetic cream to numb the nipple area. In ductal lavage, the doctor applies suction to the nipple in order to bring out fluid from the milk ducts that eventually end at the nipple. A micro-catheter is inserted into the milk duct and the fluid is w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antral Lavage
Antral lavage is a surgical procedure in which a cannula is inserted into the maxillary sinus via the inferior meatus to allow irrigation and drainage of the sinus. It is also called proof puncture, as the presence of an infection can be proven during the procedure. Upon presence of infection, it can be considered as therapeutic puncture. Often, multiple repeated lavages are subsequently required to allow for full washout of infection. In contemporary practice, endoscopic sinus surgery has largely replaced antral lavage and as such, it is rarely performed. Medical uses It can be used as therapeutic procedure for: * Acute and chronic maxillary sinusitis not responding to medical treatment. * Chronic infections not responding to treatments. * Irrigating and washing out collected purulent secretions. * Dental maxillary sinusitis. * Oro-antral fistula if associated with sinusitis. * Acute Bacterial Rhinosinusitis. Though it is indicated only in severe cases not as a reg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gastric Lavage
Gastric lavage, also commonly called stomach pumping or gastric irrigation or gastric suction, is the process of cleaning out the contents of the stomach using a tube. Since its first recorded use in the early 19th century, it has become one of the most routine means of eliminating poisons from the stomach. Such devices are normally used on a person who has ingested a poison or overdosed on a drug such as ethanol. They may also be used before surgery, to clear the contents of the digestive tract before it is opened. Apart from toxicology, gastric lavage (or nasogastric lavage) is sometimes used to confirm levels of bleeding from the upper gastrointestinal tract. It may play a role in the evaluation of hematemesis. It can also be used as a cooling technique for hyperthermic patients. Technique Gastric lavage involves the passage of a tube (such as an ''Ewald tube'') via the mouth or nose down into the stomach followed by sequential administration and removal of small volumes of ...

Arthroscopic Lavage
Arthroscopic lavage is the washing out or cleaning out the contents (blood, fluid or loose debris) inside a joint space. Lavage is a general term referring to the therapeutic washing, cleaning or rinsing. Medical uses Excessive growth of irritated synovial membrane causes it to increase its surface area by buckling into fronds, and the fronds may become inflamed and pour destructive enzymes into the joint space, causing joint swelling and joint surface destruction. Removing this excess material via lavage frequently resolves arthritic knee inflammation or pain. Arthroscopic lavage is one of many procedures available to help reverse the damage of early arthritis. There is, however, controversy about the value of simple lavage and debridement for the older patient with established osteoarthritis Osteoarthritis is a type of degenerative joint disease that results from breakdown of articular cartilage, joint cartilage and underlying bone. A form of arthritis, it is believed to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diagnostic Peritoneal Lavage
Diagnostic peritoneal lavage (DPL) or diagnostic peritoneal aspiration (DPA) is a surgical diagnostic procedure to determine if there is free floating fluid (most often blood) in the abdominal cavity. Indications This procedure is performed when intra-abdominal bleeding ( hemoperitoneum), usually secondary to trauma, is suspected. In a hemodynamically unstable patient with high-risk mechanism of injury, peritoneal lavage is a means of rapidly diagnosing intra-abdominal injury requiring laparotomy, but has largely been replaced in trauma care by the use of a focused assessment with sonography for trauma (FAST scan) due to its repeatability, non-invasiveness and non-interference with subsequent computed tomography (CT scan). Abdominal CT and contrast duodenography may complement lavage in stable patients, but in an unstable or uncooperative persons, these studies are too time-consuming or require ill-advised sedation. Magnetic resonance imaging is extremely accurate for the anatom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antiseptic Lavage
Antiseptic lavage is a means of washing, especially of a hollow organ, such as the stomach or lower bowel, with repeated injections of warm water mixed with an antiseptic or antifungal solution. Antiseptic lavages are commonly used as a treatment to pericoronitis of wisdom teeth The third molar, commonly called wisdom tooth, is the most posterior of the three molars in each quadrant of the human dentition. The age at which wisdom teeth come through ( erupt) is variable, but this generally occurs between late teens a .... Applying antibacterial solutions to wash out wounds may reduce infection rates compared with non-antibacterial products. Pumping the washing solution into the wound may reduce infections compared with other methods of washing out. References {{Treatment-stub Medical treatments ...

Nasal Irrigation
Nasal irrigation (also called nasal lavage, nasal toilet, or nasal douche) is a personal hygiene practice in which the nasal cavity is washed to flush out mucus and debris from the nose and sinuses, in order to enhance nasal breathing. Nasal irrigation can also refer to the use of saline nasal spray or nebulizers to moisten the mucous membranes. Medical uses Nasal irrigation can be an effective therapy to relieve symptoms of acute sinusitis caused by upper respiratory tract infections such as the common cold. The evidence for effectiveness in relieving chronic sinusitis is weak. It can also be useful for the temporary relief of the symptoms associated with allergic rhinitis. Adverse effects Adverse effects include nasal irritation, nosebleeds, headache, and drainage after the irrigation is done. It is generally well tolerated. There is a risk of infection if the water is not sterile or the device is not cleaned after use. If the device is used improperly this can be h ...

Chronic Wound
A chronic wound is a wound A wound is any disruption of or damage to living tissue, such as skin, mucous membranes, or organs. Wounds can either be the sudden result of direct trauma (mechanical, thermal, chemical), or can develop slowly over time due to underlying diseas ... that does not progress through the normal stages of wound healing—haemostasis, inflammation, Cell proliferation, proliferation, and Tissue remodeling, remodeling—in a predictable and timely manner. Typically, wounds that do not heal within three months are classified as chronic. Chronic wounds may remain in the inflammatory phase due to factors like infection or bacterial burden, Ischemia, ischaemia, presence of necrotic tissue, improper moisture balance of wound site, or underlying diseases such as diabetes mellitus. In acute wounds, a regulated balance of Proinflammatory cytokines, pro-inflammatory cytokines (signalling molecules) and Protease, proteases (enzymes) prevent the degradation of the extra ...

Hematopoietic Stem Cell Transplantation
Hematopoietic stem-cell transplantation (HSCT) is the transplantation of multipotent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood, in order to replicate inside a patient and produce additional normal blood cells. HSCT may be autologous (the patient's own stem cells are used), syngeneic (stem cells from an identical twin), or allogeneic (stem cells from a donor). It is most often performed for patients with certain cancers of the blood or bone marrow, such as multiple myeloma, leukemia, some types of lymphoma and immune deficiencies. In these cases, the recipient's immune system is usually suppressed with radiation or chemotherapy before the transplantation. Infection and graft-versus-host disease are major complications of allogeneic HSCT. HSCT remains a dangerous procedure with many possible complications; it is reserved for patients with life-threatening diseases. As survival following the procedure ha ...

Regenerative Medicine
Regenerative medicine deals with the "process of replacing, engineering or regenerating human or animal cells, tissues or organs to restore or establish normal function". This field holds the promise of engineering damaged tissues and organs by stimulating the body's own repair mechanisms to functionally heal previously irreparable tissues or organs. Regenerative medicine also includes the possibility of growing tissues and organs in the laboratory and implanting them when the body cannot heal itself. When the cell source for a regenerated organ is derived from the patient's own tissue or cells, the challenge of organ transplant rejection via immunological mismatch is circumvented. This approach could alleviate the problem of the shortage of organs available for donation. Some of the biomedical approaches within the field of regenerative medicine may involve the use of stem cells. Examples include the injection of stem cells or progenitor cells obtained through directed differe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
