Rocuronium, vecuronium is a muscle relaxant steroid.

This helps to relax allowing laryngeal intubation conditions.

This concept-> bufferred dissemination.

It allows the use of high doses of rocuronium in modified inductions in rapid sequence.

Nevertheless, the administration of sugammadex can enble the patient to resume spontaneous breathing should intubation fail...

However, this drug is not readily available in most regions of the world
