A preoperative machine check is imperative, yet machine faults are missed despite experience. We hypothesized that a simulation training session would improve junior residents' ability to perform a machine check beyond the level of final year residents who received only didactic training. ⋯ Our results suggest that an experiential training session allowed junior residents to achieve skills superior to those of senior colleagues after a five-year residency. This training was retained for two to four years as they continued to outperform their comparative controls.

Several fluids are available for volume therapy to address hypovolemia. We focus on two hydroxyethyl starches (HES) available for volume expansion in Canada, HES 130/0.4 (Voluven®) and HES 260/0.45 (Pentaspan®). Although information is available regarding their pharmacokinetic and risk/benefit profiles, this paper examines their viscous properties. ⋯ This study represents an innovative characterization of not only the viscosity of two commonly utilized HES solutions but also their viscous behaviour across physiologically relevant flow rates. The shear thickening behaviour of a sample of HES 130/0.40 (expiry 10/10) at high flow rates was not expected, and the effect this result may have on endothelial cell function is unknown.
