Opioid-induced hyperalgesia (OIH) or opioid-induced abnormal pain sensitivity, also called paradoxical hyperalgesia, is an uncommon condition of generalized pain caused by the long-term use of high dosages of opioids [1] such as morphine, [2] oxycodone, [3] and methadone. [4] [5] OIH is not necessarily confined to the original affected site. [6]
Opioid-induced endocrinopathy (OIE) is a complication of chronic opioid treatment. [ 1 ] [ 2 ] [ 3 ] It is a common name for all hypothalamo-pituitary axis disorders, which can be observed mostly after long term use of opioids, both as a treatment and as a substance of abuse .
Active and inactive μ-opioid receptors [1] Image of visual pain. 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.
Instead, it is a dynamic process wherein persistent painful stimuli can sensitize the system and either make pain management difficult or promote the development of chronic pain. For this reason, preemptive acute pain management may reduce both acute and chronic pain and is tailored to the surgery, the environment in which it is given (in ...
Interventional pain management or interventional pain medicine is a medical subspecialty defined by the National Uniforms Claims Committee (NUCC) as, " invasive interventions such as the discipline of medicine devoted to the diagnosis and treatment of pain related disorders principally with the application of interventional techniques in managing sub acute, chronic, persistent, and intractable ...
To maintain anesthesia, inhaled anesthetics and additional fentanyl may be used. [31] These are often given in 15–30 minute intervals throughout procedures such as endoscopy and surgeries and in emergency rooms. [32] [33] For pain relief after surgery, use can decrease the amount of inhalational anesthetic needed for emergence from anesthesia ...
General anaesthesia (UK) or general anesthesia (US) is medically induced loss of consciousness that renders a patient unarousable even by painful stimuli. [5] It is achieved through medications, which can be injected or inhaled, often with an analgesic and neuromuscular blocking agent .
Spinal anaesthesia (or spinal anesthesia), also called spinal block, subarachnoid block, intradural block and intrathecal block, [1] is a form of neuraxial regional anaesthesia involving the injection of a local anaesthetic or opioid into the subarachnoid space, generally through a fine needle, usually 9 cm (3.5 in) long.
