The aim of the study is to compare, during general anesthesia using neuromuscular blocking agent, the feasibility of a new mechanographic device (ITF handle and Visual ITF software) with a standard acceleromyographic device (TOF Watch SX) and also to assess its safety during the first 24 hours after surgery.
The two devices will be studied simultaneously in each patient.

| Measure | Description | Time Frame |
|---|---|---|
| Delay of block installation between the injection and the disappearance of all the muscular contractions to stimulation by train of four | We compare the response to curare with one side a conventional TOF Watch SX monitor and other side Handle Isometric Thumb Force. | Usefulness of non depolarizing muscle relaxant-induced muscle paralysis is limited at the surgery period and should be avoided once the surgery is completed. Therefore, all measurements are done during this time. |
| Measure | Description | Time Frame |
|---|---|---|
| Clinical examination | Appearance of the wrist skin (for example: redness, irritations or marks) | the first 24 postoperative hours |
| Clinical examination | Wrist pain |

| the first 24 postoperative hours |
| Characteristics of maintenance curarization | Value of the post-tetanus count at the time of administration of an extra bolus of rocuronium and the number of muscle contractions in response to a four-train stimulation | Usefulness of non depolarizing muscle relaxant-induced muscle paralysis is limited at the surgery period and should be avoided once the surgery is completed. Therefore, all measurements are done during this time. |
| Characteristics of decurarization during spontaneous recovery phase | Delay of the gear ratio from train of four to 25; 75 and 90%. | Usefulness of non depolarizing muscle relaxant-induced muscle paralysis is limited at the surgery period and should be avoided once the surgery is completed. Therefore, all measurements are done during this time. |
| When the TOF ratio will be greater than 0.9 on the TOF Watch side, the degree of residual paralysis will be assessed on the ITF side using 100 Hz tetanus stimulation repeated 5 times at 2 minutes interval | The response of theses tetanus stimulations will be compared with the one observed before myorelaxant administration but after induction of anesthesia | Usefulness of non depolarizing muscle relaxant-induced muscle paralysis is limited at the surgery period and should be avoided once the surgery is completed. Therefore, all measurements are done during this time. |
