Anesthesia of an area of the body through administration of a local anesthetic that blocks a group of sensory nerve fibers. Kinds of regional anesthesia include epidural anesthesia, paracervical block, pudendal block, saddle block anesthesia, and spinal anesthesia.
The use of medication to make a portion of the body unable to feel pain. Regional anesthesia works by blocking pain impulses from nerves located in the part of the body that is anesthetized. In some cases, regional anesthesia is combined with conscious sedation, leaving the person awake, relaxed, and insensitive to pain. For many types of surgery, regional anesthesia is preferred to general anesthesia because it has no effect on the respiratory system and may be safer for the patient.
Nerve or field blocking, causing loss of sensation in a dermatome innervated by a specific nerve.
The process of impeding targeted nerve pathways involves the introduction of an anesthetic substance through injection into a precise region of the body, effectively blocking sensory signals in that area.
