Clinical evaluation of Org NC 45.
Org NC 45, a new non-depolarizing neuromuscular blocking drug, was evaluated in 200 adult patients. The drug was administered in doses of 0.1, 0.15 or 0.2 mg kg-1. Intubation could be satisfactorily carried out at around 90 s in 90% of patients. The duration of clinical relaxation varied from 23 min with 0.1 mg kg-1 and neuroleptanaesthesia to 71 min with 0.2 mg kg-1 and anaesthesia with haloth...
متن کاملDose-response relation for atracurium, ORG NC 45 and pancuronium.
The potencies of atracurium, Org NC 45 and pancuronium were determined using cumulative dose-response curves. The effective doses producing 95% twitch depression were 279 microgram kg-1, 56 microgram kg-1 and 64 microgram kg-1 respectively, the relative potency being 1:5.0:4.3. The calculated log-probit dose-response curves showed the steepest slope for pancuronium, although the slopes did not ...
متن کاملClinical studies on Org NC 45: comparison with pancuronium.
Some actions of Org NC 45 have been compared with those of pancuronium in a study on 50 patients anesthetized with nitrous oxide and narcotic supplements. The train-of-four technique was used to assess the recovery of neuromuscular blockade and its antagonism. Org NC 45 was shown to have a duration of action from injection of the intubating dose (0.1 mg kg-1) to the reappearance of the first tw...
متن کاملPlacental transfer of org nc 45 in women undergoing Caesarean section.
Org NC 45 60-80 microgram kg-1 was administered to 20 pregnant women undergoing general anaesthesia for Caesarean section. Org NC 45 plasma concentrations were measured fluorimetrically in samples of maternal, venous and arterial cord blood obtained at delivery. The venous cord to maternal concentration ratio averaged 11% and was not influenced by the interval between induction and delivery. Th...
متن کاملRelative potency of ORG NC 45, pancuronium, alcuronium and tubocurarine in anaesthetized man.
The relative potency, time-course of action and cardiovascular effects of Org NC 45, a new non-depolarizing neuromuscular blocking agent, have been compared with those of pancuronium, alcuronium and tubocurarine in 64 anaesthetized patients. The relative potency (ED50) to Org NC 45 was 1.74, 3.69 and 8.57 respectively. In doses which caused useful surgical relaxation, duration of action of Org ...
