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. ...

Analgesia
Pain management is an aspect of medicine and health care involving relief of pain (pain relief, analgesia, pain control) in various dimensions, from acute and simple to chronic and challenging. Most physicians and other health professionals provide some pain control in the normal course of their practice, and for the more complex instances of pain, they also call on additional help from a specific medical specialty devoted to pain, which is called pain medicine. Pain management often uses a multidisciplinary approach for easing the suffering and improving the quality of life of anyone experiencing pain, whether acute pain or chronic pain. Relieving pain (analgesia) is typically an acute process, while managing chronic pain involves additional complexities and ideally a multidisciplinary approach. A typical multidisciplinary pain management team may include: medical practitioners, pharmacists, clinical psychologists, physiotherapists, occupational therapists, recreationa ...

Bone Fracture
A bone fracture (abbreviated FRX or Fx, Fx, or #) is a medical condition in which there is a partial or complete break in the continuity of any bone in the body. In more severe cases, the bone may be broken into several fragments, known as a ''comminuted fracture''. An open fracture (or compound fracture) is a bone fracture where the broken bone breaks through the skin. A bone fracture may be the result of high force Impact force, impact or Stress fracture, stress, or a minimal trauma injury as a result of certain medical conditions that weaken the bones, such as osteoporosis, osteopenia, bone cancer, or osteogenesis imperfecta, where the fracture is then properly termed a pathologic fracture. Most bone fractures require urgent medical attention to prevent further injury. Signs and symptoms Although bone tissue contains no nociceptors, pain receptors, a bone fracture is painful for several reasons: * Breaking in the continuity of the periosteum, with or without similar disconti ...

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, ...

Hematoma
A hematoma, also spelled haematoma, or blood suffusion is a localized bleeding outside of blood vessels, due to either disease or trauma including injury or surgery and may involve blood continuing to seep from broken capillaries. A hematoma is benign and is initially in liquid form spread among the tissues including in sacs between tissues where it may coagulate and solidify before blood is reabsorbed into blood vessels. An ecchymosis is a hematoma of the skin larger than 10 mm. They may occur among and or within many areas such as skin and other organs, connective tissues, bone, joints and muscle. A collection of blood (or even a hemorrhage) may be aggravated by anticoagulant medication (blood thinner). Blood seepage and collection of blood may occur if heparin is given via an intramuscular route; to avoid this, heparin must be given intravenously or subcutaneously. Signs and symptoms Some hematomas are visible under the surface of the skin (commonly called bruise ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
