PRIMARY outcome

Timeframe: 45 min from the time of readiness of surgery

Population: 211 patients were enrolled in the study. 106 of the enrolled patients were randomised to the Test treatment group and 105 patients to the Reference treatment group. Two subjects, one in the Test and one in the Reference treatment group discontinued the study before treatment (withdrawal by subject). In the Test treatment group, 105 patients were treated and completed the study. In the Reference treatment group, 104 patients were treated, 103 of them completed the study.

Percentage of patients with a successful block for distal upper limb surgeries, without any supplementation in the first 45 min, calculated from the time of readiness for surgery (complete sensory block).
