[Modern nondepolarizing myorelaxants in cardiac surgery].

The electromyographic and hemodynamic profile and side effects of the new nondepolarizing myorelaxants Mivacurium chloride (Mivacron), Cisathracurium besilate (Nimbex), Rocuronium bromide (Esmerone) were studied in 117 adult patients. All the test myorelaxants as bolus or infusion in a dose of 3.ED95 were found to be effective in creating adequate conditions for tracheal intubation and neuromuscular block (NMB) maintenance during operations on the coronary arteries and cardiac vales under extracorporeal circulation.
