Fracture Reduction
Reduction is a medical procedure to restore the correct anatomical alignment of a Fracture (bone), fracture or Dislocation (medicine), dislocation. When an injury results in a Bone fracture, fracture, or broken bone, the bone segments can sometimes become misaligned. This is referred to as a displaced fracture which requires the medical procedure called reduction. Some providers may refer to this as 'setting the bone'. When an injury results in a Joint dislocation, dislocation of a joint, or the misalignment of two connecting bones, a similar process of reduction must be performed to relocate the joint back into normal anatomical positioning. In the case of both displaced fractures and joint dislocation reduction is required for effective healing. Fracture Reduction There are two main categories of fracture reductions, closed reductions and open reductions. Both procedures require confirmatory imaging, such as x-ray, before the reduction to confirm the misalignment of bones and ...

Pulled Elbow
A pulled elbow, also known as nursemaid's elbow or a radial head subluxation, is when the ligament that wraps around the radial head slips off. Often a child will hold their arm against their body with the elbow slightly bent. They will not move the arm as this results in pain. Touching the arm, without moving the elbow, is usually not painful. A pulled elbow typically results from a sudden pull on an extended arm. This may occur when lifting or swinging a child by the arms. The underlying mechanism involves slippage of the annular ligament off of the head of the radius followed by the ligament getting stuck between the radius and humerus. Diagnosis is often based on symptoms. X-rays may be done to rule out other problems. Prevention is by avoiding potential causes. Treatment is by reduction. Moving the forearm into a palms down position with straightening at the elbow appears to be more effective than moving it into a palms up position followed by bending at the elbow. F ...

General Anaesthetic
General anaesthetics (or anesthetics) are often defined as compounds that induce a loss of consciousness in humans or loss of righting reflex in animals. Clinical definitions are also extended to include an induced coma that causes lack of awareness to painful stimuli, sufficient to facilitate surgical applications in clinical and veterinary practice. General anaesthetics do not act as analgesics and should also not be confused with sedatives. General anaesthetics are a structurally diverse group of compounds whose mechanisms encompass multiple biological targets involved in the control of neuronal pathways. The precise workings are the subject of some debate and ongoing research. General anesthetics elicit a state of General anaesthesia, general anesthesia. It remains somewhat controversial regarding how this state should be defined. General anesthetics, however, typically elicit several key reversible effects: immobility, analgesia, amnesia, unconsciousness, and reduced autonomi ...

Local Anesthetic
A local anesthetic (LA) is a medication that causes absence of all sensation (including pain) in a specific body part without loss of consciousness, providing local anesthesia, as opposed to a general anesthetic, which eliminates all sensation in the entire body and causes unconsciousness. Local anesthetics are most commonly used to eliminate pain during or after surgery. When it is used on specific nerve pathways ( local anesthetic nerve block), paralysis (loss of muscle function) also can be induced. Classification LAs are of 2 types: *Clinical LAs: ** amino amide LAs ** amino ester LAs *Synthetic LAs **Cocaine derivatives Synthetic cocaine-derived LAs differ from cocaine because they have a much lower abuse potential and do not cause hypertension vasoconstriction (with few exceptions). The suffix "-caine" at the ends of these medication names is derived from the word "cocaine", because cocaine was formerly used as a local anesthetic. Examples Short Duration of Act ...

Hematoma Block
A hematoma block is an analgesic technique used to allow painless manipulation of fractures while avoiding the need for full anesthesia. When a bone is fractured as a result of an injury, the two fragments may be displaced relative to each other. If they are not, usually no treatment is required other than immobilisation in an appropriate cast. If displacement does occur, then the space separating the fragments fills with blood shed by the damaged blood vessels within the bone. This collection, or pool, of blood is known as a hematoma. Injection of a suitable local anesthetic A local anesthetic (LA) is a medication that causes absence of all sensation (including pain) in a specific body part without loss of consciousness, providing local anesthesia, as opposed to a general anesthetic, which eliminates all sensati ... by needle and syringe through the skin into this hematoma produces relief of the pain caused by the fracture, allowing the bones to be painlessly manipulated. ...

Etomidate
Etomidate (United States Adopted Name, USAN, International Nonproprietary Name, INN, British Approved Name, BAN; marketed as Amidate) is a short-acting intravenous anaesthetic agent used for the induction of general anaesthesia and sedation for short procedures such as reduction of dislocated joints, tracheal intubation, cardioversion and electroconvulsive therapy. It was developed at Janssen Pharmaceutica in 1964 and was introduced as an intravenous agent in 1972 in Europe and in 1983 in the United States. The most common side effects include venous pain on injection and skeletal muscle movements. Medical uses Sedation and anesthesia In emergency settings, etomidate can be used as a sedative hypnotic agent. It is used for conscious sedation and as a part of a rapid sequence induction to induce anaesthesia. It is used as an anaesthetic agent since it has a rapid onset of action and a safe cardiovascular risk profile, and therefore is less likely to cause a significant drop in b ...

Midazolam
Midazolam, sold under the brand name Versed among others, is a benzodiazepine medication used for anesthesia, premedication before surgical anesthesia, and procedural sedation, and to treat psychomotor agitation, severe agitation. It induces sleepiness, decreases anxiety, and causes anterograde amnesia. The drug does not cause an individual to become unconscious, merely to be sedated. It is also useful for the treatment of prolonged (lasting over five minutes) seizures. Midazolam can be given Oral administration, by mouth, intravenously, by Intramuscular injection, injection into a muscle, by spraying into the intranasal, nose, or through the buccal administration, cheek. When given intravenously, it typically begins working within five minutes; when injected into a muscle, it can take fifteen minutes to begin working; when taken orally, it can take 10–20 minutes to begin working. Side effects can include a decrease in efforts to breathe, hypotension, low blood press ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propofol
Propofol is the active component of an intravenous anesthetic formulation used for induction and maintenance of general anesthesia. It is chemically termed 2,6-diisopropylphenol. The formulation was approved under the brand name Diprivan. Numerous generic versions have since been released. Intravenous administration is used to induce unconsciousness after which anesthesia may be maintained using a combination of medications. It is manufactured as part of a sterile injectable emulsion formulation using soybean oil and lecithin, giving it a white milky coloration. Recovery from propofol-induced anesthesia is generally rapid and associated with less frequent side effects (e.g., drowsiness, nausea, vomiting) compared to other anesthetic agents. Propofol may be used prior to diagnostic procedures requiring anesthesia, in the management of refractory status epilepticus, and for induction or maintenance of anesthesia prior to and during surgeries. It may be administered as a bolus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fentanyl
Fentanyl is a highly potent synthetic piperidine opioid primarily used as an analgesic (pain medication). It is 30 to 50 times more Potency (pharmacology), potent than heroin and 50 to 100 times more potent than morphine. Its primary Medicine, clinical utility is in pain management for cancer patients and those recovering from painful surgeries. Fentanyl is also used as a sedative. Depending on the method of delivery, fentanyl can be very fast acting and ingesting a relatively small quantity can cause overdose. Fentanyl works by activating μ-opioid receptors. Fentanyl is sold under the brand names Actiq, Duragesic, and Sublimaze, among others. Pharmaceutical fentanyl's adverse effects are similar to those of other opioids and narcotics including addiction, confusion, hypoventilation, respiratory depression (which, if extensive and untreated, may lead to respiratory arrest), drowsiness, nausea, visual disturbances, dyskinesia, hallucinations, delirium, a subset of the latte ...

Ketamine
Ketamine is a cyclohexanone-derived general anesthetic and NMDA receptor antagonist with analgesic and hallucinogenic properties, used medically for anesthesia, depression, and pain management. Ketamine exists as its S- (esketamine) and R- (arketamine) two enantiomers and has antidepressant action likely involving additional mechanisms than NMDA antagonism. At anesthetic doses, ketamine induces a state of dissociative anesthesia, a trance-like state providing pain relief, sedation, and amnesia. Its distinguishing features as an anesthestic are preserved breathing and airway reflexes, stimulated heart function with increased blood pressure, and moderate bronchodilation. As an anesthetic, it is used especially in trauma, Emergency medical services, emergency, and Pediatrics, pediatric cases. At lower, sub-anesthetic doses, it is used as a treatment for pain and treatment-resistant depression. Ketamine is legally used in medicine but is also tightly controlled due to ...

Anesthesiology
Anesthesiology, anaesthesiology or anaesthesia is the medical specialty concerned with the total perioperative medicine, perioperative care of patients before, during and after surgery. It encompasses anesthesia, intensive care medicine, critical emergency medicine, and pain medicine. A physician specialized in anesthesiology is called an anesthesiologist, anaesthesiologist, or anaesthetist, #Terminology, depending on the country. In some countries, the terms are synonymous, while in other countries, they refer to different positions and ''anesthetist'' is only used for non-physicians, such as nurse anesthetists. The core element of the specialty is the prevention and mitigation of pain and distress using various anesthetic agents, as well as the monitoring and maintenance of a patient's vital functions throughout the perioperative period. Since the 19th century, anesthesiology has developed from an experimental area with non-specialist practitioners using novel, untested drugs a ...
