What are the effects and indications of blocking injections

Blockade injection is a common emergency treatment method. Its main function is to relieve pain and inflammation. It is very effective in protecting the nervous system and avoiding a vicious cycle. For example, some athletes often receive blockade injections when they are injured. When conducting this type of treatment, it is important to understand some of the indications. Not all injuries are suitable for closed injections.

Sealing needle action

1. Analgesia. Local injection of anesthetic drugs can block the pain signals sent by the diseased area and has a significant analgesic effect.

2. Anti-inflammatory. Local injection of anesthetics combined with steroids can change local blood circulation, reduce inflammatory exudation, and promote the excretion of local metabolites, thereby playing an anti-inflammatory role and relieving local aseptic inflammation and soft tissue edema that stimulates the nervous system and causes soft tissue pain.

3. Protect the nervous system. Lidocaine is an anesthetic drug that has affinity for the nervous system. Local injection can block the vicious cycle of pain and allow the nervous system to rest and adjust.

4. Curative

The effect of injection is not only reflected in the literal analgesia and anti-inflammation. For some patients, injection can not only relieve the severe pain at the time, but also cure the disease, especially some chronic diseases. Clinicians will require patients to adhere to the injection therapy and not stop the medication without authorization.
