Brief summary
The purpose of this study is to determine the incidence of post-operative residual curarization in our patients and to determine if Cisatracurium and Rocuronium behave differently from each other in terms of residual curarization.
Interventions
Cisatracurium (Nimbex): * initial dose: 0.2 mg/kg * maintaining dose: 0.1 mg/kg (repeated anytime TOF-count reaches 2 twitches)
Rocuronium (Esmeron): * initial dose: 0.6 mg/kg * maintaining dose: 0.15 mg/kg (repeated anytime TOF-count reaches 2 twitches)

Eligibility
Inclusion criteria
* general anaesthesia with need to use of neuromuscular-blocking agents * awakening and extubation of the patient in the operating room and permanence in the PACU for at least 60 minutes * age 18-80 * surgical operations lasting at least 1 hour * ASA class I-III * possibility to apply TOF-monitoring with thumb-acceleromyography * women of childbearing age not using contraceptives * women of childbearing age using contraceptives
Exclusion criteria
* subjects unable to give a valid consent * patients in emergency situations * patients not awakened and not extubated in the operating room * age above 80 years or under 18 years * surgical operations lasting less than an hour * ASA class IV * impossibility to apply and/or perform TOF-monitoring * neuromuscular diseases * intake of therapies interfering with the neuromuscular function * patients having contraindications for either studied drug * pregnant women * women who are breast-feeding
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of PORC | Participants will be followed for the duration of their stay in the post-anaesthesia care unit (PACU), an expected average of 60 minutes. | To determine the incidence of post-operative residual curarization in our operating rooms, comparing two different neuromuscular-blocking agents: Cisatracurium and Rocuronium. The primary endpoint is quantified with TOF-Ratio, determined with the device TOF-Watch SX (Organon, Netherlands). A TOF-Ratio\<0.90 defines PORC. Three clinical parameters (head-tilt for 5 seconds, ability to swallow, presence of diplopia) are also evaluated. TOF-Ratios, as long as the above-mentioned clinical parameters are determined and evaluated at 15, 30 and 60 minutes after extubation of the patient. |
Secondary
| Measure | Time frame |
|---|---|
| Incidence of PORC - comparison between Cisatracurium and Rocuronium | Participants will be followed for the duration of their stay in the post-anaesthesia care unit (PACU), an expected average of 60 minutes. |
