简要总结
This randomized study prospectively evaluates our experience with administration of cisatracurium and rocuronium antagonized by sugammadex and evaluates the effects of various depths of neuromuscular blockage on providing optimal surgical conditions during laparoscopy with low-pressure capnoperitoneum.
详细描述
This randomized study prospectively evaluates our experience with administration of cisatracurium and rocuronium antagonized by sugammadex and evaluates the effects of various depths of neuromuscular blockage on providing optimal surgical conditions during laparoscopy with low-pressure capnoperitoneum.
After meeting inclusion criteria the patients will be randomized - - use of opaque envelopes, randomization into groups A and B in an operating theatre, study blinded for the patient (or his/her legal guardian) and surgeon.
Group A - muscle relaxation using rocuronium followed by sugammadex reversal (in a dose according to TOF - (train-of-four) 2-4mg/kg), depth of muscle relaxation TOF 0 PTC (post-tetanic count) 0-1 Group B - muscle relaxation using cisatracurium followed by decurarization (neostigmine 0.03 mg/kg and atropine 0.02 mg/kg)
Anesthesia management:
- intravenous cannulation, preoxygenation, sufentanil 0.2 μg/kg intravenously, propofol 2.0mg/kg and in Group A - rocuronium 0.6 mg/kg (1 mg/kg only in a case of a rapid sequence induction), in Group B - cisatracurium 0.15mg/kg
- orotracheal intubation, combined anesthesia using sevoflurane - MAC (minimal alveolar concentration) 1.0 with respect to the age of the patient
- ventilation: PCV (pressure-controlled ventilation ), PEEP (positive end-expiratory pressure) +5 cm H2O (aqua), normocapnia, FiO2 (fraction of inspired oxygen ) 1.0 until the intubation, afterwards 0.4 + AIR
- nasogastric tube placement

研究组 & 干预措施
Group A
After anesthesia induction: intravenous cannulation, preoxygenation, sufentanil 0.2 μg/kg intravenously, propofol 2.0mg/kg the neuromuscular blockade will be induced with rocuronium 0.6 mg/kg (1 mg/kg only in a case of a rapid sequence induction).
maintaining the depth of neuromuscular blockade - rocuronium: the appropriate depth of the block will be maintained with repeated boluses of rocuronium 0.3 mg/kg according to TOF 0, PTC 0-1.
Specific Neuromuscular Blockade reversal will be performed with Sugammadex intravenously. The proper dosage of sugammadex will depend on the depth of the blockade:at TOF -1-2 (train-of-four) 2m g/kg, if TOF 0 and PTC(post-tetanic count) 0-1 4mg/kg of sugammadex will be administered
干预措施: Rocuronium (Drug)
