NIMBEX (cisatracurium besylate) is a nondepolarizing skeletal muscle relaxant for intravenous administration. Compared to other neuromuscular blocking agents, it is intermediate in its onset and duration of action. Cisatracurium besylate is one of 10 isomers of atracurium besylate and constitutes approximately 15% of that mixture. Cisatracurium besylate is [1 R -[1α,2α(1' R *,2' R *)]]-2,2'-[1,5-pentanediylbis[oxy(3-oxo-3,1-propanediyl)]]bis
NIMBEX is an intermediate-onset/intermediate-duration neuromuscular blocking agent indicated for inpatients and outpatients as an adjunct to general anesthesia, to facilitate tracheal intubation, and to provide skeletal muscle relaxation during surgery or mechanical ventilation in the ICU.

Published Studies Related to Nimbex (Cisatracurium)
[Comparison of atracurium, cisatracurium and vecuronium during anaesthesia for laparoscopic surgery]. [2011.01]
BACKGROUND: The aim of the study was to compare the intubating conditions, onset time, and duration of action of atracurium, cisatracurium, and vecuronium, when used for muscle relaxation in laparoscopic surgery with carbon dioxide inflation. In trying to find an "ideal" relaxant we compared the relative potency of these drugs, and also measured pH, PaCO2 and skin temperature... CONCLUSIONS: Vecuronium, besides providing excellent conditions for tracheal intubation, had the fastest onset time and optimal duration of action. We found the drug to be the most suitable for laparoscopic surgery.
Effect of an intravenous infusion of lidocaine on cisatracurium-induced neuromuscular block duration: a randomized-controlled trial. [2010.11]
BACKGROUND: Intravenous lidocaine can be used intraoperatively for its analgesic and antihyperalgesic properties but local anaesthetics may also prolong the duration of action of neuromuscular blocking agents. We hypothesized that intravenous lidocaine would prolong the time to recovery of neuromuscular function after cisatracurium... CONCLUSIONS: No significant prolongation of spontaneous recovery of a TOF ratio >/= 0.9 after cisatracurium was found in patients receiving intravenous lidocaine. (c) 2010 The Authors.

Cisatracurium in different doses versus atracurium during general anesthesia for abdominal surgery. [2010.09]
BACKGROUND: Cisatracurium in clinical practice is devoid of histamine-induced cardiovascular effects. On the other hand, 2 ED(95) doses of cisatracurium (100 micro g/kg) do not create satisfactory intubating conditions such as those seen with equipotent doses of atracurium. The recommended intubating dose of cisatracurium is 3 ED(95). To understand this discrepancy better, we evaluated the potency and onset of atracurium and cisatracurium... CONCLUSION: The same dose (2xED(95) dose) atracurium is more effective neuromuscular blocking agent than cisatracurium, while higher doses of cisatracurium 4xED(95) and 6xED(95) provide more effective, more rapid neuromuscular blocking with longer duration of action, stable hemodynamic status, and no associated signs of histamine release clinically.
Effect of nitrous oxide on cisatracurium infusion demands: a randomized controlled trial. [2010.08.18]
ABSTRACT: BACKGROUND: Recent studies have questioned our previous understanding on the effect of nitrous oxide on muscle relaxants, since nitrous oxide has been shown to potentiate the action of bolus doses of mivacurium, rocuronium and vecuronium. This study was aimed to investigate the possible effect of nitrous oxide on the infusion requirements of cisatracurium... CONCLUSIONS: Nitrous oxide does not affect the infusion requirements of cisatracurium.

Comparison of the Effects of Vecuronium and Cisatracurium on Electrophysiologic Monitoring During Neurosurgery [Recruiting]
Recently intraoperative motor evoked potential monitoring (MEP) is widely used to reduce
neural damage during neurosurgery.
As neuromuscular blockade(NMB) during MEP monitoring decreases the amplitude of MEP, partial
NMB is usually maintained during general anesthesia. Continuous infusion of NMB agent is
preferred than bolus infusion during MEP monitoring. There are a lot of NMB agents in
clinical use. But there have been no reports about the effect of changing NMB agent on
efficacy of MEP monitoring.
Therefore, the investigators performed a randomized controlled trial to evaluate the effect
of changing NMB agent on the variability of MEP amplitude during neurosurgery.

The purpose of this study was to demonstrate in adult patients a faster recovery from a
neuromuscular block with 2. 0 mg/kg Org 25969 (sugammadex) after rocuronium as compared to 50
ug/kg neostigmine after cisatracurium when administered at reappearance of T2
Effects of Neuromuscular Blocking Agents (NMBA) on the Alteration of Transpulmonary Pressures at the Early Phase of Acute Respiratory Distress Syndrome (ARDS) [Recruiting]
Mortality in Acute Respiratory Distress Syndrome is high (40 to 60 %). Protective mechanical
ventilation, until 2010, was the cornerstone of the ARDS therapeutic strategies. Recently, a
prospective multicenter study demonstrates that a 48h continuous infusion of neuromuscular
blocking agents (NMBA) have a positive impact on mortality of ARDS patients. (Papazian et
al. ACURASYS Study. NEJM 2010; 363: 1107-16). The mechanisms through which NMBAs could
improve survival remain speculative. They are as follows:
- reduction of the consumption of oxygen linked to ventilatory workload;
- increase of chest wall compliance improving mechanical ventilation during ARDS and
better adaptation to the protective ventilation strategy;
- anti-inﬂammatory effect contributing to a reduction in pulmonary inﬂammation and
improvement in oxygenation,
- reduction of the variations of transpulmonary pressure (TPP) by the way of better
synchronisation between patient and the ventilator.
The use of NMBA could also reduce the ventilator induced lung injury by a better control of
