What it means
A depolarizing neuromuscular blocker. It works within about a minute and wears off in several minutes, so it is used for rapid-sequence intubation and short procedures. Muscles twitch briefly (fasciculations) before they go limp. It does not cause sleep or relieve pain.

For the nurse
It is given only where breathing can be fully supported, and always with a sedative, since the client cannot move or breathe but may be aware. Store and label it carefully as a paralyzing agent. Watch for high potassium in clients with burns, crush injuries or nerve damage.
