Abstract

The invention discloses a spinal canal anesthetic and its preparation method and application. The spinal canal anesthetic comprises dexmedetomidine, epinephrine, betamethasone and water for injection. The preparation method comprises the following steps: (1) after mixing betamethasone and epinephrine, adding 50% of the total amount of water for injection, and mixing uniformly; (2) adding dexmedetomidine to the mixed solution in step (1) , then add water for injection to the full amount, and mix evenly; (3) filter and sterilize the mixed solution in step (2) to obtain. The present invention also proposes the application of the spinal canal anesthetic in the preparation of spinal canal anesthetic drugs. The intraspinal anesthetic of the present invention avoids the neurotoxic effect caused by local anesthetics used in intraspinal anesthesia, has the effects of analgesia, sedation, muscle relaxation, and disappearance of adverse reflexes, and prevents shivering, and can avoid the adverse reactions of its intravenous use , can also be used for special patients.

Description

technical field

[0001] The invention belongs to the technical field of preparation and application of anesthetics, and in particular relates to a spinal anesthetic and its preparation method and application. Background technique

[0002] The existing intraspinal anesthesia is to inject local anesthetics into different cavities in the spinal canal, and the spinal nerve roots affected by the drugs are blocked or temporarily paralyzed, so that the corresponding areas dominated by the spinal nerves produce anesthesia, mainly including spinal anesthesia, Epidural anesthesia, which also includes sacral anesthesia. In the history of development, use and improvement of local anesthetics in the past 80 years, due to the irreplaceable role of local anesthetics, patients are forced to bear their neurotoxic effects, and anesthesiologists and scientific researchers have always been committed to the mechanism and mechanism of local anesthetic toxicity. However, unfortunately, all the cur...
