Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Latency time evaluation (waiting) for sensory block by the time interval spent between the withdrawal of the needle at the end of the local anesthetic injection and the absence of response to sensory impulse. | — |
Secondary
| Measure | Time frame |
|---|---|
| Motor block degree evaluation by modified Bromage scale; Motor block duration measured by the time interval between the withdrawal of the needle after the puncture and the return to level 0 in the modified Bromage scale; Cardiovascular safety evidenced by the incidence and severity of changes Blood pressure and heart rate measurements automatically by the device; Anesthesia failure: classification will be evaluated in total failure or partial failure identified by the absence or presence of sensory and motor aspects); Presence of adverse events identified by means of unexpected effects. | — |
