- ap < 0.05 versus NS period; bp < 0.05 versus H period. ΔΦ, Φpeak - Φrest; Φpeak, maximal blood flow during reactive hyperaemia; H period, set of measurements obtained when the patients were sedated by midazolam; HS period, set of measurements obtained when the patients were sedated by midazolam and sufentanil; NS period, set of measurements obtained when the patients were non-sedated; PU, perfusion units; T1/2 R, time to half flow normalisation; TP, time to peak; TR, time to flow normalisation.
