b. Anesthetic. Anesthetic refers to a technique or medication that partially or
completely eliminates sensation or feeling. There are two types of nerve-blocking
anesthetics, local and regional. Local anesthetics block sensory nerve pathways at the
organ level. Regional anesthetics block sensory nerve pathways along the course of
tissues. Refer to figure 4-3 for the level of anesthesia necessary for cesarean and
vaginal delivery.
