  2. Cryoneurolysis - Wikipedia

    en.wikipedia.org/wiki/Cryoneurolysis

    Cryoneurolysis treatments that use nitrous oxide (boiling point of −88.5 °C) as the coolant fall in the range of an axonotmesis injury, or 2nd degree injury, according to the Sunderland classification system. [1] Treatments of the nerve in this temperature range are reversible, usually within a few months.

  3. Nitrous oxide (medication) - Wikipedia

    en.wikipedia.org/wiki/Nitrous_oxide_(medication)

    Nitrous oxide, as medical gas supply, is an inhaled gas used as pain medication, and is typically administered with 50% oxygen mix. It is often used together with other medications for anesthesia . [ 2 ]

  4. Nitrous oxide - Wikipedia

    en.wikipedia.org/wiki/Nitrous_oxide

    Nitrous oxide is a colourless gas with a faint, sweet odour. Nitrous oxide supports combustion by releasing the dipolar bonded oxygen radical, and can thus relight a glowing splint. N 2 O is inert at room temperature and has few reactions. At elevated temperatures, its reactivity increases. For example, nitrous oxide reacts with NaNH

  5. Postoperative nausea and vomiting - Wikipedia

    en.wikipedia.org/wiki/Postoperative_nausea_and...

    Anesthetic risk factors include the use of volatile anesthetics, nitrous oxide (N 2 O), opioids, and longer duration of anesthesia. Patient factors that confer increased risk for PONV include female gender, obesity , age less than 16 years, past history of motion sickness or chemotherapy-induced nausea, high levels of preoperative anxiety , and ...

  6. Nerve injury - Wikipedia

    en.wikipedia.org/wiki/Nerve_injury

    This type of nerve damage may cause paralysis of the motor, sensory, and autonomic functions, and is mainly seen in crush injury. [2] If the force creating the nerve damage is removed in a timely fashion, the axon may regenerate, leading to recovery. Electrically, the nerve shows rapid and complete degeneration, with loss of voluntary motor units.

  7. Neurectomy - Wikipedia

    en.wikipedia.org/wiki/Neurectomy

    As cutaneous nerves cover all areas of the skin, and any surgery which requires incisions may inadvertently cause injury or scarring, now entrapping a cutaneous nerve. [ 15 ] A common tradeoff when electing to a neurectomy is that numbness along the nerve distribution is expected.

  8. Twilight anesthesia - Wikipedia

    en.wikipedia.org/wiki/Twilight_anesthesia

    Twilight anesthesia is also known as twilight sleep and allows an easy awakening and a speedy recovery time for the patient. Anesthesia is used to control pain by using medicines that reversibly block nerve conduction near the site of administration, therefore, generating a loss of sensation at the area administered. Close monitoring by the ...

  9. Neurotoxicity - Wikipedia

    en.wikipedia.org/wiki/Neurotoxicity

    As a result, the increased concentration of Ca 2+ directly increases the stress on mitochondria, resulting in excessive oxidative phosphorylation and production of reactive oxygen species (ROS) via the activation of nitric oxide synthase, ultimately leading to cell death. Aβ was also found aiding this route to neurotoxicity by enhancing neuron ...
