Ringer's Solution
Ringer's solution is a solution of several salts dissolved in water for the purpose of creating an isotonic solution relative to the body fluids of an animal. Ringer's solution typically contains sodium chloride, potassium chloride, calcium chloride and sodium bicarbonate, with the last used to balance the pH. Other additions can include chemical fuel sources for cells, including ATP and dextrose, as well as antibiotics and antifungals. Composition Ringer's solution typically contains NaCl, KCl, CaCl2 and NaHCO3, sometimes with other minerals such as MgCl2, dissolved in distilled water. The precise proportions of these vary from species to species, particularly between marine osmoconformers and osmoregulators. Uses Ringer's solution is frequently administered to human and veterinary patients for intravenous or subcutaneous hydration and to expand the vascular compartment in hypovolemia. It is also use in ''in vitro'' experiments on organs or tissues, such as ''in vitro'' m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Needle lavage should not be used in an attempt to treat persons seeking long-term relief for symptomatic osteoarthritis of the knee., which cites * * The use of this treatment in this cas ...

Ringer's Lactate Solution
Ringer's lactate solution (RL), also known as sodium lactate solution, Lactated Ringer’s, and Hartmann's solution, is a mixture of sodium chloride, sodium lactate, potassium chloride, and calcium chloride in water. It is used for replacing fluids and electrolytes in those who have low blood volume or low blood pressure. It may also be used to treat metabolic acidosis and to wash the eye following a chemical burn. It is given by intravenous infusion or applied to the affected area. Side effects may include allergic reactions, high blood potassium, hypervolemia, and high blood calcium. It may not be suitable for mixing with certain medications and some recommend against use in the same infusion as a blood transfusion. Ringer's lactate solution has a lower rate of acidosis as compared with normal saline. Use is generally safe in pregnancy and breastfeeding. Ringer's lactate solution is in the crystalloid family of medications. It is isotonic, i.e. it has the same tonicity as bl ...

Sodium Lactate
Sodium lactate is the sodium salt of lactic acid, and has a mild saline taste. It is produced by fermentation of a sugar source, such as corn or beets, and then, by neutralizing the resulting lactic acid to create a compound having the formula NaC3H5O3. Sodium lactate is used as a medication, and is included on the World Health Organization's List of Essential Medicines. Uses Food industry As a food additive, sodium lactate has the E number E325 and is naturally a liquid product, but also is available in powder form. It acts as a preservative, acidity regulator, and bulking agent. Despite the similarity in name, sodium lactate itself is not chemically similar to lactose (milk sugar), so need not be restricted by those with lactose intolerance. Cosmetics and personal care products Sodium lactate is sometimes used in shampoo products and other similar items such as liquid soaps, as it is an effective humectant and moisturizer. Medical use Sodium lactate is used to treat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexis Hartmann
Alexis Frank Hartmann Sr. (October 30, 1898 – September 6, 1964) was an American pediatrician and clinical biochemist. He is best known for adding sodium lactate to Ringer's solution, creating what is now known as Ringer's lactate solution or Hartmann's solution for intravenous infusions. Early life Hartmann was born in October 30, 1898 in St. Louis, Missouri. His parents were Henry Charles Hartmann, a general practitioner, and Bertha Hauck Griesedick; both were of German ancestry. He enrolled at Washington University in St. Louis, receiving a bachelor's degree in 1919 and master's and medical degrees in 1921. While he was a medical student, he developed a new technique to test blood sugar levels. Career Hartmann completed his residency in pediatrics at St. Louis Children's Hospital in 1923. He was an instructor in pediatrics at Washington University, his alma mater, and was promoted to assistant professor in 1925 then associate professor in 1927. He was promoted to ...

Sydney Ringer
Sydney Ringer FRS (March 1835 – 14 October 1910) was a British clinician, physiologist and pharmacologist, best known for inventing Ringer's solution. He was born in 1835 in Norwich, England and died following a stroke in 1910 in Lastingham, Yorkshire, England. His gravestone and some other records report 1835 for his birth, some census records and other documents suggest 1836, but his baptismal record at St Mary's Baptist Chapel (referred to in Ringer's own will) confirms this was 1835. Life Born into a non-conformist family (often, but incorrectly described as 'Quaker') in Norwich, Ringer's father died in 1843, while he was still very young. Ringer's early education was at a Baptist school in Norwich founded by the father of John Sherren Brewer Jnr. His school fellows included the headmaster's grandson Henry William Brewer, later a notable architectural illustrator, as well as the orientalist Professor Robert Lubbock Bensly and the architect Edward Boardman. A significant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dehydration
In physiology, dehydration is a lack of total body water, with an accompanying disruption of metabolic processes. It occurs when free water loss exceeds free water intake, usually due to exercise, disease, or high environmental temperature. Mild dehydration can also be caused by immersion diuresis, which may increase risk of decompression sickness in divers. Most people can tolerate a 3-4% decrease in total body water without difficulty or adverse health effects. A 5-8% decrease can cause fatigue and dizziness. Loss of over ten percent of total body water can cause physical and mental deterioration, accompanied by severe thirst. Death occurs at a loss of between fifteen and twenty-five percent of the body water.Ashcroft F, Life Without Water in Life at the Extremes. Berkeley and Los Angeles, 2000, 134-138. Mild dehydration is characterized by thirst and general discomfort and is usually resolved with oral rehydration. Dehydration can cause hypernatremia (high levels of sodium ...

Extracellular Fluid
In cell biology, extracellular fluid (ECF) denotes all body fluid outside the cells of any multicellular organism. Total body water in healthy adults is about 60% (range 45 to 75%) of total body weight; women and the obese typically have a lower percentage than lean men. Extracellular fluid makes up about one-third of body fluid, the remaining two-thirds is intracellular fluid within cells. The main component of the extracellular fluid is the interstitial fluid that surrounds cells. Extracellular fluid is the internal environment of all multicellular animals, and in those animals with a blood circulatory system, a proportion of this fluid is blood plasma. Plasma and interstitial fluid are the two components that make up at least 97% of the ECF. Lymph makes up a small percentage of the interstitial fluid. The remaining small portion of the ECF includes the transcellular fluid (about 2.5%). The ECF can also be seen as having two components – plasma and lymph as a delivery system ...

Intravenous Infusion
Intravenous therapy (abbreviated as IV therapy) is a medical technique that administers fluids, medications and nutrients directly into a person's vein. The intravenous route of administration is commonly used for rehydration or to provide nutrients for those who cannot, or will not—due to reduced mental states or otherwise—consume food or water per os, by mouth. It may also be used to administer pharmaceutical drug, medications or other medical therapy such as blood transfusion, blood products or electrolytes to correct electrolyte imbalances. Attempts at providing intravenous therapy have been recorded as early as the 1400s, but the practice did not become widespread until the 1900s after the development of techniques for safe, effective use. The intravenous route is the fastest way to deliver medications and fluid replacement throughout the body as they are introduced directly into the circulatory system and thus quickly distributed. For this reason, the intravenous route o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Septic Arthritis
Acute septic arthritis, infectious arthritis, suppurative arthritis, osteomyelitis, or joint infection is the invasion of a joint by an infectious agent resulting in joint inflammation. Generally speaking, symptoms typically include redness, heat and pain in a single joint associated with a decreased ability to move the joint. Onset is usually rapid. Other symptoms may include fever, weakness and headache. Occasionally, more than one joint may be involved, especially in neonates and younger children. In neonates, infants during the first year of life, and toddlers, the signs and symptoms of septic arthritis can be deceptive and mimic other infectious and non-infectious disorders. In children, septic arthritis is usually caused by non-specific bacterial infection and commonly hematogenous, i.e., spread through the bloodstream. Septic arthritis and/or acute hematogenous osteomyelitis usually occurs in children with no co-occurring health problems. Other routes of infection include ...

In Vitro Muscle Testing
''In vitro'' muscle testing is a method used to characterize properties of living muscle tissue after removing it from an organism, which allows more extensive and precise quantification of its properties than ''in vivo'' testing. ''In vitro'' muscle testing has provided the bulk of scientific knowledge of muscle structure and physiology, and how both relate to organismal performance. Isolation of tissue Once an appropriate animal has been selected—whether for a specific locomotor function (i.e. frogs for jumping); or a specific animal strain, to answer a research question—a specific muscle is identified based on its ''in vivo'' function and fibre type distribution. Following ethical approval, and if necessary, government approval, the animal is humanely euthanised. Humane methods differ by country, with the most appropriate based on ethical approval and researcher skill level. A number of further criteria should be followed to ensure the animal is completely dead without the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
