Self-surgery
Self-surgery is the act of performing a surgery, surgical procedure on oneself. It can be an act taken in extreme circumstances out of necessity, an attempt to avoid embarrassment, legal action, or financial costs, or a rare manifestation of a psychological disorder. Genitals These surgeries are generally the least life-threatening. Sometimes people resort to self-surgery in the form of castration in an attempt to control their sexual urges, or due to gender dysphoria. Boston Corbett, the soldier who killed Abraham Lincoln's assassin John Wilkes Booth, had performed self-surgery earlier in life. He castration, castrated himself with a pair of scissors in order to avoid the temptation of prostitutes. Afterwards, he went to a prayer meeting and ate a meal before going for medical treatment. Abdominal Successful abdominal self-surgery is extremely rare. A few well-publicized cases have found their way into the medical literature. *On February 15, 1921, Evan O'Neill Kane carried out h ...

Evan O'Neill Kane
Evan O'Neill Kane (April 6, 1861 – April 1, 1932) was an American physician and surgeon from the 1880s to the early 1930s who served as chief of surgery at Kane Summit Hospital in Kane, Pennsylvania. He was a significant contributor in his day to railway surgery; that is, the medical and managerial practices directed toward occupational health and accident-related trauma surgery for railroad workers. Kane was also a well published contributor of innovations in surgical procedures and equipment, including asbestos bandages, mica windows for brain surgery, and multiple site hypodermoclysis. Kane was convinced that particular surgeries need not involve general anesthesia. He is most well known, both in his own time and today, for demonstrating this by performing self-surgery in 1921 to remove his own vermiform appendix, appendix under local anesthetic. In 1932 at age 70, he very publicly again performed self-surgery to repair a hernia. Some of Kane’s practices were idiosyncra ...

Surgery
Surgery is a medical specialty that uses manual and instrumental techniques to diagnose or treat pathological conditions (e.g., trauma, disease, injury, malignancy), to alter bodily functions (e.g., malabsorption created by bariatric surgery such as gastric bypass), to reconstruct or alter aesthetics and appearance (cosmetic surgery), or to remove unwanted tissue (biology), tissues (body fat, glands, scars or skin tags) or foreign bodies. The act of performing surgery may be called a surgical procedure or surgical operation, or simply "surgery" or "operation". In this context, the verb "operate" means to perform surgery. The adjective surgical means pertaining to surgery; e.g. surgical instruments, operating theater, surgical facility or surgical nurse. Most surgical procedures are performed by a pair of operators: a surgeon who is the main operator performing the surgery, and a surgical assistant who provides in-procedure manual assistance during surgery.

Orchiectomy
Orchiectomy (also named orchidectomy) is a surgery, surgical procedure in which one or both testicles are removed. The surgery can be performed for various reasons: *treatment for testicular cancer *as part of gender-affirming surgery for transgender women *as management for advanced prostate cancer *to remove damaged testes after testicular torsion. *after a trauma or complex rupture of the tunica albuginea. *as a treatment for post vasectomy pain syndrome. Less frequently, orchiectomy may be performed following a trauma, or due to wasting away of one or more testicles. Procedure Simple orchiectomy A simple orchiectomy is commonly performed as part of gender-affirming surgery for transgender women, or as palliative treatment for advanced cases of prostate cancer. A simple orchiectomy may also be required in the event of testicular torsion. For the procedure, the person lies flat on an operating table with the Human penis, penis taped against the abdomen. The nurse shaves a sm ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Hemostasis
In biology, hemostasis or haemostasis is a process to prevent and stop bleeding, meaning to keep blood within a damaged blood vessel (the opposite of hemostasis is hemorrhage). It is the first stage of wound healing. Hemostasis involves three major steps: * vasoconstriction * temporary blockage of a hole in a damaged blood vessel by a platelet plug * blood coagulation (formation of fibrin clots) Coagulation, the changing of blood from a liquid to a gel which forms the fibrin clots, is essential to hemostasis. Intact blood vessels moderate blood's tendency to form clots. The endothelial cells of intact vessels prevent blood clotting with a heparin-like molecule and thrombomodulin, and prevent platelet aggregation with nitric oxide and prostacyclin. When endothelium of a blood vessel is damaged, the endothelial cells stop secretion of coagulation and aggregation inhibitors and instead secrete von Willebrand factor, which initiates the maintenance of hemostasis after in ...

Lidocaine
Lidocaine, also known as lignocaine and sold under the brand name Xylocaine among others, is a local anesthetic of the amino amide type. It is also used to treat ventricular tachycardia and ventricular fibrillation. When used for local anaesthesia or in nerve blocks, lidocaine typically begins working within several minutes and lasts for half an hour to three hours. Lidocaine mixtures may also be applied directly to the skin or mucous membranes to numb the area. It is often used mixed with a small amount of adrenaline (epinephrine) to prolong its local effects and to decrease bleeding. If injected intravenously, it may cause cerebral effects such as confusion, changes in vision, numbness, tingling, and vomiting. It can cause low blood pressure and an irregular heart rate. There are concerns that injecting it into a joint can cause problems with the cartilage. It appears to be generally safe for use in pregnancy. A lower dose may be required in those with liver problems. I ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Retractor (medical)
A retractor is a surgical instrument used to separate the edges of a surgical incision/wound or to hold away certain organs and tissues (i.e. to provide tissue ''retraction'') so that body parts underneath may be accessed during surgical operations. The broad term ''retractor'' typically describes a simple steel tool possessing a curved, hooked, or angled blade, which is manually manipulated to help maintain a desired position of tissue during surgery. More sophisticated retractors may be clamped in place (usually to a tableside frame) or suspended at the end of a robotic arm. Retractors can also be "self-retaining" and no longer need to be held once inserted, having two or more opposing blades or hooks which are separated via spring, ratchet, worm gear or other method. The term ''retractor'' is also used to describe distinct, hand-cranked devices such as rib spreaders (also known as thoracic retractors, or distractors) with which surgeons may use to forcefully drive tissues apa ...

Scalpel
A scalpel or bistoury is a small and extremely sharp bladed instrument used for surgery, anatomical dissection, podiatry and various handicrafts. A lancet is a double-edged scalpel. Scalpel blades are usually made of hardened and tempered steel, stainless steel, or high carbon steel; in addition, titanium, ceramic, diamond and even obsidian knives are not uncommon. For example, when performing surgery under MRI guidance, steel blades are unusable (the blades would be drawn to the magnets and would also cause image artifacts). Historically, the preferred material for surgical scalpels was silver. Scalpel blades are also offered by some manufacturers with a zirconium nitride–coated edge to improve sharpness and edge retention. Others manufacture blades that are polymer-coated to enhance lubricity during a cut. Scalpels may be single-use disposable or re-usable. Re-usable scalpels can have permanently attached blades that can be sharpened or, more commonly, removable ...

Adrenaline
Adrenaline, also known as epinephrine, is a hormone and medication which is involved in regulating visceral functions (e.g., respiration). It appears as a white microcrystalline granule. Adrenaline is normally produced by the adrenal glands and by a small number of neurons in the medulla oblongata. It plays an essential role in the fight-or-flight response by increasing blood flow to muscles, heart output by acting on the SA node, pupil dilation response, and blood sugar level. It does this by binding to alpha and beta receptors. It is found in many animals, including humans, and some single-celled organisms. It has also been isolated from the plant '' Scoparia dulcis'' found in Northern Vietnam. Medical uses As a medication, it is used to treat several conditions, including allergic reaction anaphylaxis, cardiac arrest, and superficial bleeding. Inhaled adrenaline may be used to improve the symptoms of croup. It may also be used for asthma when other treatments a ...

Hydrocortisone
Hydrocortisone is the name for the hormone cortisol when supplied as a medication. It is a corticosteroid and works as an anti-inflammatory and by immune suppression. Uses include conditions such as adrenocortical insufficiency, adrenogenital syndrome, high blood calcium, thyroiditis, rheumatoid arthritis, dermatitis, asthma, and COPD. It is the treatment of choice for adrenocortical insufficiency. It can be given by mouth, topically, rectally or by injection. Stopping treatment after long-term use should be done slowly. Common side effects may include mood changes, increased appetite, hyperglycemia, hypertension, and edema (swelling). With long-term use, common side effects include osteoporosis, adrenal insufficiency, upset stomach, physical weakness, easy bruising, and candidiasis (yeast infections). It is unclear if it is safe for use during pregnancy. Hydrocortisone was patented in 1936 and approved for medical use in 1941. It is on the World Health Orga ...

Barbiturate
Barbiturates are a class of depressant, depressant drugs that are chemically derived from barbituric acid. They are effective when used medication, medically as anxiolytics, hypnotics, and anticonvulsants, but have physical and psychological addiction potential as well as overdose potential among other possible adverse effects. They have been recreational drug use, used recreationally for their anti-anxiety and sedative effects, and are thus prohibition of drugs, controlled in most countries due to the risks associated with such use. Barbiturates have largely been replaced by benzodiazepines and nonbenzodiazepines ("Z-drugs") in routine medical practice, particularly in the treatment of anxiety disorders and insomnia, because of the significantly lower risk of overdose, and the lack of an antidote for barbiturate overdose. Despite this, barbiturates are still in use for various purposes: in general anesthesia, epilepsy, treatment of acute migraines or cluster headaches, acute t ...

Abscess
An abscess is a collection of pus that has built up within the tissue of the body, usually caused by bacterial infection. Signs and symptoms of abscesses include redness, pain, warmth, and swelling. The swelling may feel fluid-filled when pressed. The area of redness often extends beyond the swelling. Carbuncles and boils are types of abscess that often involve hair follicles, with carbuncles being larger. A cyst is related to an abscess, but it contains a material other than pus, and a cyst has a clearly defined wall. Abscesses can also form internally on internal organs and after surgery. They are usually caused by a bacterial infection. Often many different types of bacteria are involved in a single infection. In many areas of the world, the most common bacteria present is ''methicillin-resistant Staphylococcus aureus''. Rarely, parasites can cause abscesses; this is more common in the developing world. Diagnosis of a skin abscess is usually made based on what it looks ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
