It is well known that suspension laryngoscopy (SL) produces marked hemodynamic changes. Coughing during extubation sometimes causes adverse clinical problems. We investigated whether 10% lidocaine spray could attenuate hemodynamic stress responses due to SL and reduce coughing incidence during extubation. Sixty patients undergoing SL were randomly divided into two groups ...

BACKGROUND AND OBJECTIVES: Ankle-brachial index (ABI) is currently recommended for the screening of peripheral arterial disease. However, this method becomes less reliable in the presence of calcified, incompressible arteries, as they result in an erroneously elevated ABI, and an additional measure termed the toe-brachial index (TBI) is recommended. The evaluation ...

Under pressure, people often prefer what is familiar, which can seem safer than the unfamiliar. We show that such favoring of familiarity can lead to choices precisely contrary to the source of felt pressure, thus exacerbating, rather than mitigating, its negative consequences. In Experiment 1, time pressure increased participants' frequency ...
