Medical Procedure
A medical procedure is a course of action intended to achieve a result in the delivery of healthcare. A medical procedure with the intention of determining, measuring, or diagnosis, diagnosing a patient condition or parameter is also called a medical test. Other common kinds of procedures are therapeutic (i.e., intended to treat, cure, or restore function or structure), such as surgery, surgical and Physical medicine and rehabilitation, physical rehabilitation procedures.

Renal Replacement Therapy
Renal replacement therapy (RRT) is therapy that replaces the normal blood-filtering function of the kidneys. It is used when the kidneys are not working well, which is called kidney failure and includes acute kidney injury and chronic kidney disease. Renal replacement therapy includes dialysis (hemodialysis or peritoneal dialysis), hemofiltration, and hemodiafiltration, which are various ways of filtration of blood with or without machines. Renal replacement therapy also includes kidney transplantation, which is the ultimate form of replacement in that the old kidney is replaced by a donor kidney. These treatments are not truly cures for kidney disease. In the context of chronic kidney disease, they are more accurately viewed as life-extending treatments, although if chronic kidney disease is managed well with dialysis and a compatible graft is found early and is successfully transplanted, the clinical course can be quite favorable, with life expectancy of many years.

Intracorporeal
Intracorporeal or intracorporal is an adjective that means within ''(intra-)'' the body ''(corpus)''. Its antonym is extracorporeal. It is used frequently in medicine to describe medical procedures that occur within the body, or within a corpus, as opposed to extracorporeal procedures (e.g. extracorporeal membrane oxygenation). In a medical or surgical context, it may refer to: * Intracorporeal anastomosis * Intracorporeal circulation * Intracorporeal energy harvesting, harvesting energy from the body, and storing it, to sustain a medical device (e.g. a pacemaker). * Intracorporeal injection * Intracorporeal microrobotics * Intracorporeal reconstruction * Intracorporeal suturing * Intracorporeal urinary diversion * Lithotripsy: ** Intracorporeal electrohydraulic lithotripsy ** Intracorporeal laser lithotripsy ** Intracorporeal pneumatic lithotripsy ** Intracorporeal shock wave lithotripsy See also * * * Human body (''corpus humanum'') * ''In vivo Studies t ...

Radiotherapy
Radiation therapy or radiotherapy (RT, RTx, or XRT) is a treatment using ionizing radiation, generally provided as part of cancer therapy to either kill or control the growth of malignant cells. It is normally delivered by a linear particle accelerator. Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body, and have not spread to other parts. It may also be used as part of adjuvant therapy, to prevent tumor recurrence after surgery to remove a primary malignant tumor (for example, early stages of breast cancer). Radiation therapy is synergistic with chemotherapy, and has been used before, during, and after chemotherapy in susceptible cancers. The subspecialty of oncology concerned with radiotherapy is called radiation oncology. A physician who practices in this subspecialty is a radiation oncologist. Radiation therapy is commonly applied to the cancerous tumor because of its ability to control cell growth. Ionizin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extracorporeal Shockwave Lithotripsy
Extracorporeal shockwave therapy (ESWT) is a treatment using powerful acoustic pulses which is mostly used to treat kidney stones and in physical therapy and orthopedics. Medical uses The most common use of extracorporeal shockwave therapy (ESWT) is for lithotripsy to treat kidney stones (urinary calculosis) and biliary calculi (stones in the gallbladder or in the liver) using an acoustic pulse. It is also reported to be used for salivary stones and pancreatic stones. In the UK, the National Institute for Health and Care Excellence (NICE) found that the evidence for ESWT in the majority of indications is conflicting, and therefore ESWT should only be used where there are special arrangements for clinical governance and audit. Two 2017 reviews had similar findings, with moderate level evidence at best. Extracorporeal shockwave therapy is used as a second line measure to treat tennis elbow, shoulder rotator cuff pain, Achilles tendinitis, plantar fasciitis, and greater tr ...

Liver Support System
A liver support system or diachysis is a type of therapeutic device to assist in performing the functions of the liver. Such systems focus either on removing the accumulating toxins (liver dialysis), or providing additional replacement of the metabolic functions of the liver through the inclusion of hepatocytes to the device (bioartificial liver device). A diachysis machine is used for acute care i.e. emergency care, as opposed to dialysis machinewhich are typically used over the longer term. These systems are being trialed to help people with acute liver failure (ALF) or acute-on-chronic liver failure. The primary functions of the liver include removing toxic substances from the blood, manufacturing blood proteins, storing energy in the form of glycogen, and secreting bile. The hepatocytes that perform these tasks can be killed or impaired by disease, resulting in acute liver failure (ALF) which can be seen in person with previously diseased liver or a healthy one.

Cardiopulmonary Bypass
Cardiopulmonary bypass (CPB) or heart-lung machine, also called the pump or CPB pump, is a machine that temporarily takes over the function of the heart and lungs during open-heart surgery by maintaining the circulation of blood and oxygen throughout the body. As such it is an Extracorporeal, extracorporeal device. CPB is operated by a perfusionist. The machine mechanically circulates and oxygenates blood throughout the patient's body while bypassing the heart and lungs allowing the surgeon to work in a bloodless surgical field. Uses CPB is commonly used in operations or surgical procedures involving the heart. The technique allows the surgical team to oxygenate and circulate the patient's blood, thus allowing the surgeon to operate safely on the heart. In many operations, such as Coronary artery bypass surgery, coronary artery bypass grafting (CABG), the heart is Cardioplegia, arrested, due to the degree of the difficulty of operating on a beating heart. Operations requiring t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extracorporeal Membrane Oxygenation
Extracorporeal membrane oxygenation (ECMO) is a form of extracorporeal life support, providing prolonged cardiac and respiratory system, respiratory support to people whose human heart, heart and human lung, lungs are unable to provide an adequate amount of oxygen, gas exchange or blood supply (perfusion) to sustain life. The technology for ECMO is largely derived from cardiopulmonary bypass, which provides shorter-term support with arrested native circulation. The device used is a membrane oxygenator, also known as an artificial lung. ECMO works by temporarily drawing blood from the body to allow artificial oxygenation of the red blood cells and removal of carbon dioxide. Generally, it is used either post-cardiopulmonary bypass or in late-stage treatment of a person with profound heart and/or lung failure, although it is now seeing use as a treatment for cardiac arrest in certain centers, allowing treatment of the underlying cause of arrest while circulation and oxygenation are ...

Extracorporeal Carbon Dioxide Removal
Extracorporeal carbon dioxide removal (ECCO2R) is the removal of carbon dioxide (CO2) from the bloodstream in people who have elevated levels of carbon dioxide as a result of respiratory failure. The use of extracorporeal carbon dioxide removal is currently considered experimental, but it has been studied in a number of situations, specifically severe exacerbations of chronic obstructive pulmonary disease and in adult respiratory distress syndrome where conventional mechanical ventilation Mechanical ventilation or assisted ventilation is the Medicine, medical term for using a ventilator, ventilator machine to fully or partially provide artificial ventilation. Mechanical ventilation helps move air into and out of the lungs, wit ... would cause excessive lung damage. It requires the insertion of a tube similar to a dialysis catheter into a large vein. Blood is pumped through a machine where the carbon dioxide is filtered out. References Intensive care medicine Extracorpo ...

Continuous Renal Replacement Therapy
Hemofiltration, also haemofiltration, is a renal replacement therapy which is used in the intensive care setting. It is usually used to treat acute kidney injury (AKI), but may be of benefit in multiple organ dysfunction syndrome or sepsis. During hemofiltration, a patient's blood is passed through a set of tubing (a ''filtration circuit'') via a machine to a semipermeable membrane (the ''filter'') where waste products and water (collectively called ''ultrafiltrate'') are removed by convection. Replacement fluid is added and the blood is returned to the patient. As in dialysis, in hemofiltration one achieves movement of solutes across a semi-permeable membrane. However, solute movement with hemofiltration is governed by convection rather than by diffusion. With hemofiltration, dialysate is not used. Instead, a positive hydrostatic pressure drives water and solutes across the filter membrane from the blood compartment to the filtrate compartment, from which it is drained. Solutes, ...
