Muscle relaxants can be used for which of the following?

A. To facilitate intubation.

B. To provide optimal surgical conditions.

C. To optimize ventilator support.

DISCUSSION: Muscle relaxants are administered to facilitate endotracheal intubation, to provide the surgeon with optimal working conditions during anesthesia, and to optimize mechanical ventilator support in some patients. They do not produce analgesia, sedation, or amnesia. Therefore, muscle paralysis should not be performed without sedation or general anesthesia.
