Reducing Sternal Wound Infection Rates in Patients Undergoing Cardiothoracic Surgery with Sternotomy.

Local Problem: Sternal wound infections (SWIs), whether superficial or deep, are associated with increased morbidity, mortality, and costs. From 2016 to 2017, our facility saw a 50% decrease in SWIs among patients undergoing cardiothoracic surgery with sternotomy. From 2017 to 2018, however, we identified a 33% increase in SWIs, prompting us to address our cardiac nurses' sternal wound care education and practice.

Evaluating the Effectiveness of an Alternating Pressure Overlay in Patients Undergoing Cardiothoracic Surgery.

Local Problem: In 2019 and the first half of 2020, our facility experienced an increase in the number and severity of hospital-acquired pressure injuries (HAPIs) among our cardiothoracic surgery population. Fifty percent of these HAPIs occurred within 72 hours of surgery. A review of the literature revealed that alternating pressure overlays (APOs) have been successfully used to prevent HAPIs in surgical patients.

Incorporation of Fiber Bragg Sensors for Shape Memory Polyurethanes Characterization.

Shape memory polyurethanes (SMPUs) are thermally activated shape memory materials, which can be used as actuators or sensors in applications including aerospace, aeronautics, automobiles or the biomedical industry. The accurate characterization of the memory effect of these materials is therefore mandatory for the technology's success. The shape memory characterization is normally accomplished using mechanical testing coupled with a heat source, where a detailed knowledge of the heat cycle and its influence on the material properties is paramount but difficult to monitor.
