Description

technical field [0001] The invention belongs to the field of medicine, in particular to a compound lidocaine facial mask liquid for anesthesia and its preparation method and application. Background technique [0002] The skin is one of the main sensory organs of the human body. When treating related diseases or related operations through the skin, the patient is more sensitive to pain. In order to reduce the pain of the patient, an anesthetic is usually applied to a specific part of the skin for surface anesthesia during the operation. Absorption of anesthetic drugs reduces the sensitivity of skin pain receptors, thereby reducing pain. [0003] Lidocaine is a commonly used anesthetic. At present, compound lidocaine is widely used in the form of injections, creams and patches. Injections are mainly used for local anesthesia before surgery, requiring special personnel to operate, and are prone to infection, so the scope of application is relatively limited; creams and patches...
