  • 基于电子病历管理的ICU医护共同查房模式对临时医嘱执行效率的影响

    目的 探讨基于电子病历(EMR)系统的重症医学科胸外ICU医护共同查房模式对临时医嘱执行效率的影响。 方法 随机选取2010年4月-2011年11月入住ICU且实行EMR管理的200例患者及30名管床护士、10名一线医生为调查对象,回顾比较基于EMR模式下医护分离查房和医护共同查房两种方式对临时医嘱执行的效果及满意度。 结果 采取医护共同查房模式后,患者及管床护士对临时医嘱执行的满意度提高(P<0.05),临时医嘱平均执行时间较以前增快(P<0.000 01),护理差错率减少(P=0.04)。 结论 医护共同查房模式可行,对ICU临时医嘱的执行效率有良好的促进作用,值得推广。

  • Research on Fast Implementation Method of Image Gaussian RBF Interpolation Based on CUDA

    Image interpolation is often required during medical image processing and analysis. Although interpolation method based on Gaussian radial basis function (GRBF) has high precision, the long calculation time still limits its application in field of image interpolation. To overcome this problem, a method of two-dimensional and three-dimensional medical image GRBF interpolation based on computing unified device architecture (CUDA) is proposed in this paper. According to single instruction multiple threads (SIMT) executive model of CUDA, various optimizing measures such as coalesced access and shared memory are adopted in this study. To eliminate the edge distortion of image interpolation, natural suture algorithm is utilized in overlapping regions while adopting data space strategy of separating 2D images into blocks or dividing 3D images into sub-volumes. Keeping a high interpolation precision, the 2D and 3D medical image GRBF interpolation achieved great acceleration in each basic computing step. The experiments showed that the operative efficiency of image GRBF interpolation based on CUDA platform was obviously improved compared with CPU calculation. The present method is of a considerable reference value in the application field of image interpolation.
