RESUMEN
Objective To design a kind of special support mattress for the endoscopic retrograde cholangiopancreatography (ERCP), and to improve the comfort of the patients during the procedure, and evaluate the efficacy and safety during clinical application. Methods By 3D modeling, we designed a special memory foam mattress for ERCP. From January 2014 to September 2014, 424 patients who underwent ERCP treatment without general anesthesia and could take semi-prone position, were divided into special mattress group (210 cases) and ordinary mattress group (214 cases) according to the random number table method. The satisfaction of the patients and the operators of the two groups were evaluated and compared. Results The operation times of the two groups were (32.9±18.5) min and (33.2±20.1) min, respectively, and there was no significant difference between the two groups (P>0.05). The overall satisfaction ratings of the patients in the two groups were (7.9±1.6) points and (6.3±1.3) points, respectively (P0.05). No mattress related complications were found. Conclusions The special memory foam mattress for ERCP can alleviate the discomfort and improve the tolerance during the procedure. Therefore, it is worth promoting the application.
