A patient asks a nurse to explain the differences between general anesthesia and regional anesthesia. What is the correct response?
A. "General anesthesia inhibits peripheral nerve conduction."
B. "Under general anesthesia all sensation and consciousness is lost."
C. "Under general anesthesia there is a loss of sensation in a specific area of the body."
D. "General anesthesia is routinely used for procedures that only require a decreased level of consciousness."
B
Local anesthesia involves loss of sensation at the desired site by inhibiting peripheral nerve con-duction. Regional anesthesia results in loss of sensation in an area of the body by anesthetizing sensory pathways. Moderate sedation/analgesia (conscious sedation) is routinely used for diag-nostic or therapeutic procedures that do not require complete anesthesia but simply a decreased level of consciousness.
