Foley Catheter
In urology, a Foley catheter is one of many types of urinary catheters (UC). The Foley UC was named after Frederic Foley, who produced the original design in 1929. Foleys are indwelling UC, often referred to as an IDCs (sometimes IDUCs). This differs from in/out catheters (with only a single tube and no valves, designed to go into the bladder, drain it, and come straight back out). The UC is a flexible tube if it is indwelling and stays put, or rigid (glass or rigid plastic) if it is in/out, that a clinician, or the client themselves, often in the case of in/out UC, passes it through the urethra and into the Urinary bladder, bladder to drain urine. Foley and similar brand catheters usually have two separated channels, or Lumen (anatomy), ''lumina'' (or ''lumen''), running down its length. One lumen, opens at both ends, drains urine into a collection bag. The other has a valve on the outside end and connects to a balloon at the inside tip. The balloon is inflated with sterile water ...

Frederic Foley
Dr. Frederic Eugene Basil Foley, MD (April 5, 1891 – March 24, 1966) was an American urologist who designed the Foley catheter. Biography Frederic Foley was born in St. Cloud, Minnesota in 1891. He studied languages at Yale University, receiving a bachelor's degree in 1914, and then trained in medicine at the Johns Hopkins School of Medicine until his graduation in 1918. He subsequently worked with William Halsted and Harvey Cushing, and worked at the Peter Bent Brigham Hospital, Boston on the junior surgical staff. Although there is no record of his training in urology, he was certified by the American Board of Urology in 1937. Foley worked as a urologist in Boston, Massachusetts and later became chief of urology at Ancker Hospital in St. Paul, Minnesota. (Ancker Hospital was renamed St. Paul Ramsey Medical Center and is now known as Regions Hospital.) He died in 1966 of lung cancer.

Ultrasound Scan ND 013
Ultrasound is sound with frequencies greater than 20 kilohertz. This frequency is the approximate upper audible limit of human hearing in healthy young adults. The physical principles of acoustic waves apply to any frequency range, including ultrasound. Ultrasonic devices operate with frequencies from 20 kHz up to several gigahertz. Ultrasound is used in many different fields. Ultrasonic devices are used to detect objects and measure distances. Ultrasound imaging or sonography is often used in medicine. In the nondestructive testing of products and structures, ultrasound is used to detect invisible flaws. Industrially, ultrasound is used for cleaning, mixing, and accelerating chemical processes. Animals such as bats and porpoises use ultrasound for locating prey and obstacles. History Acoustics, the science of sound, starts as far back as Pythagoras in the 6th century BC, who wrote on the mathematical properties of stringed instruments. Echolocation in bats was ...

Coma
A coma is a deep state of prolonged unconsciousness in which a person cannot be awakened, fails to Nociception, respond normally to Pain, painful stimuli, light, or sound, lacks a normal Circadian rhythm, sleep-wake cycle and does not initiate voluntary actions. The person may experience respiratory and circulatory problems due to the body's inability to maintain normal bodily functions. People in a coma often require extensive medical care to maintain their health and prevent complications such as pneumonia or blood clots. Coma patients exhibit a complete absence of wakefulness and are unable to consciously feel, speak or move. Comas can be the result of natural causes, or can be Induced coma, medically induced, for example, during General anaesthesia, general anesthesia. Clinically, a coma can be defined as the consistent inability to follow a one-step command. For a patient to maintain consciousness, the components of ''wakefulness'' and ''awareness'' must be maintained. Wak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedation
Sedation is the reduction of irritability or agitation by administration of sedative drugs, generally to facilitate a medical procedure or diagnostic procedure. Examples of drugs which can be used for sedation include isoflurane, diethyl ether, propofol, etomidate, ketamine, pentobarbital, lorazepam and midazolam. Medical uses Sedation is typically used in minor surgical procedures such as endoscopy, vasectomy, or dentistry and for reconstructive surgery, some cosmetic surgeries, removal of wisdom teeth, or for high-anxiety patients. Sedation methods in dentistry include inhalation sedation (using nitrous oxide), oral sedation, and intravenous (IV) sedation. Inhalation sedation is also sometimes referred to as "relative analgesia". Sedation is also used extensively in the intensive care unit so that patients who are being mechanical ventilation, ventilated tolerate having an endotracheal tube in their vertebrate trachea, trachea. It can also be used during a long term brain EEG ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anesthesia
Anesthesia (American English) or anaesthesia (British English) is a state of controlled, temporary loss of sensation or awareness that is induced for medical or veterinary purposes. It may include some or all of analgesia (relief from or prevention of pain), paralysis (muscle relaxation), amnesia (loss of memory), and unconsciousness. An individual under the effects of anesthetic drugs is referred to as being anesthetized. Anesthesia enables the painless performance of procedures that would otherwise require physical restraint in a non-anesthetized individual, or would otherwise be technically unfeasible. Three broad categories of anesthesia exist: * ''General anesthesia'' suppresses central nervous system activity and results in unconsciousness and total lack of Sensation (psychology), sensation, using either injected or inhaled drugs. * ''Sedation'' suppresses the central nervous system to a lesser degree, inhibiting both anxiolysis, anxiety and creation of long-term memory, ...

End-of-life Care
End-of-life care is health care provided in the time leading up to a person's death. End-of-life care can be provided in the hours, days, or months before a person dies and encompasses care and support for a person's mental and emotional needs, physical comfort, spiritual needs, and practical tasks. End-of-life care is most commonly provided at home, in the hospital, or in a long-term care facility with care being provided by family members, nurses, social workers, physicians, and other support staff. Facilities may also have palliative or hospice care teams that will provide end-of-life care services. Decisions about end-of-life care are often informed by medical, financial and ethical considerations. In most developed countries, medical spending on people in the last twelve months of life makes up roughly 10% of total aggregate medical spending, while those in the last three years of life can cost up to 25%.

Urinary Retention
Urinary retention is an inability to completely empty the bladder. Onset can be sudden or gradual. When of sudden onset, symptoms include an inability to urinate and lower abdominal pain. When of gradual onset, symptoms may include urinary incontinence, loss of bladder control, mild lower abdominal pain, and a weak urine stream. Those with long-term problems are at risk of urinary tract infections. Causes include blockage of the urethra, nerve problems, certain medications, and weak bladder muscles. Blockage can be caused by benign prostatic hyperplasia (BPH), urethral strictures, bladder stones, a cystocele, constipation, or tumors. Nerve problems can occur from diabetes, trauma, spinal cord injury, spinal cord problems, stroke, or heavy metal poisoning. Medications that can cause problems include anticholinergics, antihistamines, tricyclic antidepressants, cyclobenzaprine, diazepam, nonsteroidal anti-inflammatory drugs (NSAID), stimulants, and opioids.

ABIM Foundation
Choosing Wisely is a United States–based health educational campaign, led by the ABIM Foundation ( American Board of Internal Medicine), about unnecessary health care. The campaign identifies over 500 tests and procedures and encourages doctors and patients to discuss, research, and possibly get second opinions, before proceeding with them. To conduct the campaign, the ABIM Foundation asks medical specialty societies to make five to ten recommendations for preventing overuse of a treatment in their field. The foundation then publicizes this information, and the medical specialty societies disseminate it to their members. The campaign has garnered both praise and criticism, and some of its ideas have spread to other countries. It does not include evaluation of its effects on costs, on discussions or on medical outcomes. Some doctors have said they lack time for the recommended discussions.

Joseph-Frédéric-Benoît Charrière
Joseph-Frédéric-Benoît Charrière (March 19, 1803 – April 28, 1876) was a Swiss-born French manufacturer of surgical instruments. Charrière was born in Cerniat, in the Canton of Fribourg, Switzerland. He moved to Paris at age 13, and was apprenticed to a manufacturer of knives. In 1820, he founded a company manufacturing surgical instruments, which quickly grew to 400 employees by around 1840, and was world-famous by his death. He became a naturalized French citizen in 1843. He developed and improved a number of instruments, especially hypodermic needles and catheters; the French catheter scale is named after his work. In order to achieve this, Charrière benefitted from at the time newly developed materials such as nickel silver, stainless steel, and rubber. Several of his apprentices also became well-known instrument makers, including Georges-Guillaume-Amatus Lüer, Louis-Joseph Mathieu, and Adolphe Collin in Paris; Josef Leiter in Vienna; and Camillus Nyrop in C ...

French Catheter Scale
The French scale, also known as the French gauge or Charrière system, is a widely used measurement system for the size of catheters. It is commonly abbreviated as Fr but may also be abbreviated as Fg, FR or F, and less frequently as CH or Ch (referencing its inventor, Charrière). However, the term ''gauge'', abbreviated ''G'' or ''ga'', typically refers to the Birmingham gauge for hypodermic needles. The French scale measures and is proportional to the outer diameter of a catheter, with 1 French (Fr) defined as millimeter, making the relationship: 1 mm = 3 Fr. Thus, the outer diameter of a catheter in millimeters can be calculated by dividing the French size by 3. For example, a catheter with a French size of 9 would have an outer diameter of approximately 3mm. While the French scale aligns closely with the metric system, it introduces redundancy and the potential for rounding errors. This metrication problem is further complicated in medical contexts where metric and im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
