Introduction
Nerve block anesthesia refers to a method in which anesthetic agents are injected around peripheral nerve trunks or plexuses to temporarily interrupt the conduction of nerve impulses, thereby causing temporary loss of pain sensation in the area innervated by the targeted nerve. Nerve block anesthesia is suitable for surgical procedures confined to regions innervated by specific peripheral nerves or nerve plexuses.
Neuraxial block anesthesia refers to a method in which anesthetic agents are injected around peripheral nerve trunks or plexuses to temporarily interrupt the conduction of nerve impulses, thereby causing transient loss of pain sensation in the area innervated by the targeted nerve.
This type of anesthesia is suitable when the surgical procedure is confined to regions supplied by specific peripheral nerves or nerve plexuses, and the duration of anesthesia required can be adequately achieved. While there are no special timing requirements for performing the block, certain contraindications exist for patient selection, including coagulation disorders, infection at the injection site, severe anatomical deformities, or known allergy to local anesthetics. Neuraxial block anesthesia is currently considered a relatively safe technique with a low incidence of complications; however, potential risks such as systemic toxicity, nerve injury, and infection may still occur.
After administering neuraxial block anesthesia, close monitoring of the patient's vital signs is essential. If any adverse reactions or discomfort occur following anesthesia, appropriate interventions should be promptly initiated.
