The investigators hypothesize that by monitoring and analyzing physiological parameters (heart rate, blood pressure, saturation) and well-being (pain, nausea, vomiting, comfort) the SMART ANGEL ™ device improves the quality of care after major or intermediate outpatient surgery. This active surveillance will result in a decrease in the rate of unplanned recourse (hospitalization, consultation, telephone call).
