Using a monitored sip test to assess risk of aspiration in perioperative patients.

• PULMONARY ASPIRATION is associated with high morbidity and mortality rates. Older adult patients have been shown to be particularly at risk for aspiration.<br /><br />• A RANDOMIZED CONTROLLED TRIAL was conducted to investigate the efficacy of a simple, noninvasive screening test—the monitored sip test—in identifying patients at risk for aspiration, including “silent aspirators.”<br /><br />• BASED ON CLINICAL JUDGMENT using the study's outcome measures, incidence of aspiration-related lung injury was high (ie, 37.5%); however, no identification of patients at risk for aspiration occurred after either the use of the monitored sip test or routine cautious introduction of fluids during the data collection phase of the study.<br />
