[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.
Comparative evaluation of atracurium dosed on ideal body weight vs. total body weight in morbidly obese patients. [2011.01]
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT: Different conflicting reports have been published for the use of atracurium in morbidly obese patients. Dosing of atracurium based on lean body mass, total body weight, and total body weight with a dose reduction for every 10 kg more than 70 kg have been proposed. WHAT THIS STUDY ADDS: The current prospective randomized double-blind study compares atracurium 0.5 mg kg(-1) ideal body weight vs. 0.5 mg kg(-1) total body weight when used as a muscle relaxant in morbidly obese patients undergoing bariatric surgery. Based on our results in patients with body weights varying from 112 to 260 kg, we have concluded that atracurium 0.5 mg kg(-1) ideal body weight results in a predictable profile of muscle relaxation allowing for adequate intubation conditions and recovery of muscle strength within 60 min with lack of need for antagonism. A dose-dependent prolongation of action is shown when dosing is based on total body weight. AIMS: This double-blind randomized study evaluated atracurium dosing based on ideal body weight vs. total body weight for muscle relaxation in morbidly obese patients undergoing bariatric surgery... CONCLUSION: In morbid obesity (112-260 kg), atracurium 0.5 mg kg(-1) ideal body weight results in a predictable profile of muscle relaxation allowing for adequate intubation conditions and recovery of muscle strength to a TOF ratio >90% within 60 min with lack of need for antagonism. A dose-dependent prolongation of action is shown when dosing is based on total body weight. (c) 2010 The Authors.

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.

Clinical Trials Related to Atracurium
Peri -and Postoperative Drug Therapy Schedules for Morbidly Obese Patients [Completed]
Rationale: Obesity is an increasing health risk worldwide, with the USA recording prevalence
in adults of around 20%. The mean body weight of obese patients is also increasing. One of
the strategies to treat extreme obesity (Body Mass Index (BMI) > 40 kg/m2) is
weight-reducing surgery like laparoscopic gastric banding or gastric bypass. During
anaesthesia, morbidly obese patients are exposed to an increased risk at developing
postoperative wound infections, apnoea and thrombotic events and may be more difficult to
intubate. Routinely, amongst others, cefazolin, morphine, nadroparin and atracurium are
administered in standard dosages. However, it is not known to what extend the
pharmacokinetics and/or - dynamics of these drugs are affected in morbidly obese patients.
Therefore, evidence-based dosing schedules for these drugs in morbidly obese patients should
Objective: The study is performed in order to develop population pharmacokinetic and/or
pharmacodynamic models of the routinely used drug therapies during bariatric surgery in
morbidly obese patients (BMI > 40 kg/m2): cefazolin, morphine, nadroparin and atracurium.
A covariate analysis will be performed in order to account for variability in
pharmacokinetic and/or pharmacodynamic parameters. This covariate analysis will take into
account procedure and patient bound covariates, with specific interest for body weight as a
covariate. Whenever possible, non-obese patients will be included in the covariate analysis.
The results will be used to develop individualised dosing schemes for routinely used drugs
peri-operatively in morbidly obese patients.
Study design: A randomised, prospective, observational, therapeutic and invasive study.
Study population: Morbidly obese patients with a Body Mass Index > 40 kg/m2 undergoing
laparoscopic banding or gastric bypass surgery, 18-60 years old. A total of 20 patients will
be included in the study.
Intervention (if applicable): All measurements and data collection will take place around
administration of drugs that are given according to routine clinical practice (cefazolin 2
grams for prophylaxis of infections, morphine 10 mg intravenously at the end of surgery, a
patient-controlled analgesia (PCA) pump with morphine for postoperative pain relief and
nadroparin 0,6 ml for trombo-embolic prophylaxis). For muscle relaxation, patients are
randomised to receive one of two generally accepted dosing regimen of atracurium (0. 5 mg/kg
based on ideal body weight or 0. 5 mg/kg based on total body weight). Peri- and
postoperatively, a maximum amount of 70 ml of blood will be collected from an indwelling
arterial line for measurement of concentrations of cefazolin, morphine, and anti-Xa
(nadroparin). One week after surgery the patient will be checked for thrombosis using
Main study parameters/endpoints:
Primary endpoints to evaluate in morbidly obese patients are;
- pharmacokinetic parameters of cefazolin in blood;
- pharmacokinetic parameters of morphine and metabolites in blood;
- time course of anti-factor Xa levels in blood following nadroparin;
- time course of the pharmacodynamic effect of atracurium.
Secondary endpoints to evaluate in morbidly obese patients are:
- to compare primary endpoints (obtained in morbidly obese patients) with data of
- the occurrence of postoperative wound infections;
- postoperative pain scores, sedation scores and nausea scores;
- the occurrence of bleedings or thrombotic events ;
- required amounts of morphine (PCA);
- to compare the time course of the pharmacodynamic effect of two different doses of

Effect of Deep BLock on Intraoperative Surgical Conditions [Recruiting]
Rationale: A deep neuromuscular block is often associated with improved surgical conditions
especially in laparoscopic surgery. However, a deep block comes at the expense of a variety
of items that may conflict with the use of a deep surgical muscle blockade including a long
recovery phase, the need for muscle reversal, postoperative ventilation, impaired
postoperative breathing. With the introduction of Sugammadex there is now the possibility to
reverse an even deep surgical block. This may overcome most if not all of the issues
Objective: To assess whether a deep neuromuscular block provides better surgical conditions
than a moderately deep block as derived from a surgical rating score.
Study design: Single center, double-blind randomized controlled trial. Study population: 24
ASA I-III patients scheduled for laparoscopic renal (n=12, GROUP 1) or prostatic surgery
(n=12, GROUP 2).
Intervention: In both GROUP 1 and GROUP 2, 6 six patients will receive neuromuscular
blockade according to current practice (atracurium (bolus) plus mivacurium (cont. infusion))
aimed at a moderately deep neuromuscular block (1-2 twitches in the Train of Four (TOF)
monitor). The other six will receive a bolus plus continuous infusion with rocuronium aimed
at a deep neuromuscular block (1-2 twitches post tetanic count (PTC)). All surgical
procedures will be performed by one surgeon.
Main study parameters/endpoints: To study the surgical conditions in patients undergoing
laparoscopic renal or prostate surgery during deep versus less deep neuromuscular block as
assessed by the surgical rating score.
Nature and extent of the burden and risks associated with participation, benefit and group
relatedness: Compared to current practice there will be no additional risk.
