按摩推拿护理对胸外科手术患者的效果分析

目的:研究按摩推拿护理对胸外科手术患者的效果。方法:选取中山市人民医院胸外科就诊的136位手术患者,采用随机数字表法分为研究组70例,对照组66例。对照组采用常规综合护理,研究组在常规综合护理基础上进行按摩推拿护理。比较患者对护理方式的认可度,患者肺功能指标、排痰情况,以及不良反应发生情况。结果:通过记录各项指标,通过按摩推拿护理的研究组的患者认可度显著较高(P<0.05),研究组肺功能指标显著优于对照组(P<0.05),而且研究组的排痰量较显著(P<0.05),进而研究组发生的不良反应较少,不良反应率较低,和对照组相比,差异具有统计学意义(P<0.05)。结论:按摩推拿护理对胸外科手术患者能够有效地增加肺通气量,增加显著的排痰次数和排痰量,避免不良反应的发生,值得胸外科手术推广。

Numerical simulation of the pulsing air separation field based on CFD

The flow field of pulsing air separation is normally in an unsteady turbulence state.With the application of the basic principles of multiphase turbulent flows,we established the dynamical computational model,which shows a remarkable variation of the unstable pulsing air flow field.CFD(computational fluid dynamics) was used to conduct the numerical simulation of the actual geometric model of the classifier.The inside velocity of the flowing fields was analyzed later.The simulation results indicate that the designed structure of the active pulsing air classifier provided a favorable environment for the separation of the particles with different physical characters by density.We shot the movement behaviors of the typical tracer grains in the active pulsing flow field using a high speed dynamic camera.The displacement and velocity curves of the particles in the continuous impulse periods were then analyzed.The experimental results indicate that the effective separation by density of the particles with the same settling velocity and different ranges of the density and particle size can be achieved in the active pulsing airflow field.The experimental results provide an agreement with the simulation results.
