Example text

Hypothermia and acidosis slow down its metabolism; in fact, we keep it in a refrigerator until we’re ready to use it. Pancuronium is an older, long-acting muscle relaxant with a unique twist of its own: vagal blockade. It’s used when we want to speed up heart rate and support blood pressure. Pancuronium is partially metabolized by the liver and excreted by the kidneys, so compromise of either system will extend its action. One might ask why we give nondepolarizers instead of additional doses of succinylcholine, since the nondepolarizing blockade looks just like succinylcholine’s phase II block when we test with the nerve stimulator.

The BIS gives us the answer. If the patient has a BIS reading well below 60 and is hypotensive, the anesthetic level 30 ANESTHESIA CRASH COURSE can be decreased safely. If the BIS is elevated and the patient is hypotensive, as with trauma patients, the treatment is to administer fluids or vasopressors. We’ve talked about how much anesthesia a patient requires; let’s talk for a moment about how quickly we can increase or decrease the level he or she is getting. Some inhaled anesthetics are quicker than others and the reason isn’t very intuitive.

When we give a dose of succinylcholine and check it with the nerve stimulator, the response to a train of four is constant but less than normal; it does not get stronger after a tetanic stimulus. Interestingly, this changes with a second dose. With a second dose, “fade” happens—meaning that the twitches grow progressively weaker but get stronger after a tetanic stimulus. We call those a “phase I block” and “phase II block,” respectively. Phase II block is unpredictable, long-lasting, and not pharmacologically reversible; we avoid it whenever possible.
