The peritoneum is the serous membrane forming the lining of the abdominal cavity or coelom in amniotes and some invertebrates, such as annelids. It covers most of the intra-abdominal organs, and is composed of a layer of mesothelium supported by a thin layer of connective tissue. This peritoneal lining of the cavity supports many of the abdominal organs and serves as a conduit for their blood vessels, lymphatic vessels, and nerves.
Kidney dialysis is the process of removing excess water, solutes, and toxins from the blood in people whose kidneys can no longer perform these functions naturally. This is referred to as renal replacement therapy. The first successful dialysis was performed in 1943.
Peritonitis is inflammation of the localized or generalized peritoneum, the lining of the inner wall of the abdomen and cover of the abdominal organs. Symptoms may include severe pain, swelling of the abdomen, fever, or weight loss. One part or the entire abdomen may be tender. Complications may include shock and acute respiratory distress syndrome.
Kidney failure, also known as end-stage kidney disease, is a medical condition in which the kidneys can no longer adequately filter waste products from the blood, functioning at less than 15% of normal levels. Kidney failure is classified as either acute kidney failure, which develops rapidly and may resolve; and chronic kidney failure, which develops slowly and can often be irreversible. Symptoms may include leg swelling, feeling tired, vomiting, loss of appetite, and confusion. Complications of acute and chronic failure include uremia, hyperkalaemia, and volume overload. Complications of chronic failure also include heart disease, high blood pressure, and anaemia.
The mesothelium is a membrane composed of simple squamous epithelial cells of mesodermal origin, which forms the lining of several body cavities: the pleura, peritoneum and pericardium.
Peritoneal dialysis (PD) is a type of dialysis which uses the peritoneum in a person's abdomen as the membrane through which fluid and dissolved substances are exchanged with the blood. It is used to remove excess fluid, correct electrolyte problems, and remove toxins in those with kidney failure. Peritoneal dialysis has better outcomes than hemodialysis during the first couple of years. Other benefits include greater flexibility and better tolerability in those with significant heart disease.
The peritoneal cavity is a potential space between the parietal peritoneum and visceral peritoneum. The parietal and visceral peritonea are layers of the peritoneum named depending on their function/location. It is one of the spaces derived from the coelomic cavity of the embryo, the others being the pleural cavities around the lungs and the pericardial cavity around the heart.
Caulobacter is a genus of Gram-negative bacteria in the class Alphaproteobacteria. Its best-known member is Caulobacter crescentus, an organism ubiquitous in freshwater lakes and rivers; many members of the genus are specialized to oligotrophic environments.
In medicine, Kt/V is a number used to quantify hemodialysis and peritoneal dialysis treatment adequacy.
Standardized Kt/V, also std Kt/V, is a way of measuring (renal) dialysis adequacy. It was developed by Frank Gotch and is used in the United States to measure dialysis. Despite the name, it is quite different from Kt/V. In theory, both peritoneal dialysis and hemodialysis can be quantified with std Kt/V.
Pneumoperitoneum is pneumatosis in the peritoneal cavity, a potential space within the abdominal cavity. The most common cause is a perforated abdominal organ, generally from a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma. A perforated appendix seldom causes a pneumoperitoneum.
Alcaligenes is a genus of Gram-negative, aerobic, rod-shaped bacteria. The species are motile with amphitrichous flagella and rarely nonmotile. It is a genus of non-fermenting bacteria. Additionally, some strains of Alcaligenes are capable of anaerobic respiration, but they must be in the presence of nitrate or nitrite; otherwise, their metabolism is respiratory and never fermentative. Strains of Alcaligenes are found mostly in the intestinal tracts of vertebrates, decaying materials, dairy products, water, and soil; they can be isolated from human respiratory and gastrointestinal tracts and wounds in hospitalized patients with compromised immune systems. They are occasionally the cause of opportunistic infections, including nosocomial sepsis.
In nephrology, the peritoneal equilibration test (PET), is a tool used by nephrologists to determine the characteristics of the peritoneal membrane mass transport characteristics, when assessing a patient for peritoneal dialysis.
Icodextrin is a colloid osmotic agent, derived from maltodextrin, used in form of an aqueous solution for peritoneal dialysis under the trade name Extraneal, and after gynecological laparoscopic surgery for the reduction of post-surgical adhesions under the trade name Adept.
Brevibacterium is a genus of bacteria of the order Micrococcales. They are Gram-positive soil organisms.
Radioiodinated serum albumin, abbreviated RISA, is a marker used in identifying blood plasma via the dilution method in renal physiology.
Doxercalciferol (or 1-hydroxyergocalciferol, trade name Hectorol) is drug for secondary hyperparathyroidism and metabolic bone disease. It is a synthetic analog of ergocalciferol (vitamin D2). It suppresses parathyroid synthesis and secretion.
Sucroferric oxyhydroxide, sold under the brand name Velphoro, is a non-calcium, iron-based phosphate binder used for the control of serum phosphorus levels in adults with chronic kidney disease (CKD) on haemodialysis (HD) or peritoneal dialysis (PD). It is used in form of chewable tablets.
Qian Jiaqi, also romanized as Jia-Qi Qian, was a Chinese nephrologist and professor at Renji Hospital of Shanghai Jiao Tong University School of Medicine. He was the first clinical physician to perform hemodialysis and peritoneal dialysis in China, and established a Kt/V value of at least 1.7 as the target for peritoneal dialysis.
Encapsulating peritoneal sclerosis (EPS) is a medical condition that causes the encapsulation of feces within a thickened fibrocollagenous peritoneal membrane, which leads to recurrent episodes of bowel obstruction. It is a rare serious complication typically caused by peritoneal dialysis.
