ESRA19-0278 Sufentanil sublingual tablet system (SSTS) in post-operative pain: a case series
Background and aims SSTS is a preprogrammed, non invasive, patient-activated bed-side system that enables patients to manage moderate-severe acute pain in a hospital setting. Our aim is to evaluate efficacy, ease of use of SSTS, patients and nurses’ satisfaction. Methods We evaluate pain control and general satisfaction in patients treated with SSTS after general or orthopedic prosthetic surgery. Enrollment started on April the 1st at Policlinico Paolo Giaccone in Palermo and is still ongoing. SSTS allows patients to self-administer a 15-μg sufentanil tablet sublingually with a 20-minute lockout, up to 72 hours. We visit patients three times per day, recording pain control (NRS scale), arte…
Mechanism of large oscillations of anodic potential during anodization of silicon in H3PO4/HF solutions
Abstract Effect of large oscillations of electrical potential during anodic polarization of silicon in electrolytes composed of phosphoric and hydrofluoric acids has been reported. The oscillations last hours without damping if experimental conditions are optimal. Changes of temperature, anodic current density, intensity of stirring, etc. quench them or convert into less periodic ones. The oscillations are of very high amplitude (typically 15 V) with a period ranging from 18 to 30 s. Scanning electron microscopy (SEM)-imaging of the samples experiencing the oscillatory kinetic behaviour shows unambiguously that the stage of the anodic voltage growth is assisted by the formation of a thin (5…
