Rocuronium has been said to have an initially rapid onset of action followed by a slower final approach to maximum effect, the supporting data showing only that time to 75% of blockade is more rapid. Expressions of velocity are derived from basic measures such as length and time. The aim of our study was to confirm the onset characteristics of rocuronium by using appropriate expressions of velocity. ⋯ Using appropriate expressions and calculations, we can unequivocally conclude that rocuronium has a biphasic onset that is initially rapid and then slower. The rate of action is nearly 6 times faster at the beginning.

Case Reports[Refractory hypotension during anesthesia in a patient treated with angiotensin receptor blockers].
A 66-year-old woman treated with valsartan, an angiotensin II receptor blocker, and diuretics was scheduled for surgery to remove a pelvic mass. Both drugs were withdrawn 24 hours before anesthetic induction. ⋯ When hypotension developed and was refractory to fluid replacement and phenylephrine administration, terlipressin, a vasopressin receptor antagonist, was infused and outcome was favorable. Anesthetized patients treated with angiotensin II receptor blockers to control hypertension may experience hypotensive events that are refractory to standard treatment but that respond to vasopressin receptor antagonists.
