Sequelae Of Medical Nerve Block Injection

The sequelae of nerve block injection may result in nerve damage, local anesthetic poisoning, vascular injury, bleeding and hematoma, and even paraplegia. Injection of nerve block needle is a kind of blind puncture, which may cause reversible or permanent damage to human nerve roots. Reversible nerve damage will automatically recover in a short time, and permanent nerve damage will cause perceptual and motor nerve disorders. During blind puncture of nerve block needle, blood vessels will be damaged, and a small amount of anesthetic liquid may be injected into blood vessels, causing local anesthetic poisoning. If blood vessels are damaged, coagulation function will be poor and local hematoma will be formed. If anesthetics are injected into the spinal canal, it may compress the spinal nerve and cause paralysis, resulting in irreversible neurological complications. To inject the nerve block needle to a regular third-class hospital, we must be careful to choose the use.
