一次性电动脉冲冲洗吸引器临床试验研究

Clinical trial study on disposable electric pulse flushing suction apparatus

目的探讨一次性电动脉冲冲洗吸引器的临床使用效果,为开放性手术提供一种选择方法。方法选取2011年5月～2013年2月收治的60例开放性伤口的患者分为常规冲洗(对照组28例)和一次性电动脉冲冲洗器冲洗(实验组32例),评价两组红、肿、热、渗液及试验前后细菌计数及菌落结果。结果使用一次性电动脉冲冲洗吸引器的患者创面除红外,肿、热痛渗液等临床观察指标与对照组有显著性差异(P<0.05),两组试验后菌落计数比较差异具有统计学意义(P<0.05)。两组在临床试验前渗液细菌培养结果比较,差异有统计学意义(P<0.05);经临床试验后两组渗液细菌培养结果比较,差异均无统计学意义(P>0.05)。结论一次性电动脉冲冲洗吸引器能够有效地清除外科清创术中细菌污染,和常规冲洗一样有效、安全,有一定的推广价值。

Objective To investigate the clinical using effect of disposable electric pulse flushing suction apparatus, and to provide a selection method for open surgery. Methods Sixty cases of patients with open wounds admitted into hospital from May 2011 to February 2013 were divided into conventional washing group with 28 cases and disposable electric pulse flushing suction apparatus group with 32 cases, evaluated the redness, swolling, heat, seepage and results of bacteria count and bacterial colonies before and after test of the two groups. Results Except the redness, the swolling, heat and seepage of experimental group were more significantly different than that in control group （P〈0.05）, the bacteria count between the two groups group after the test was significant difference （P〈0.05）, there were significant differences between the two groups in bacterial culture results of seepage before the test （P〈0.05）, there were no signifi- cant difference between the two groups in bacterial culture results of seepage after the test （P〉0.05）. Conclusion Dispos- able electric pulse flushing suction apparatus can effectively remove bacteria pollution in surgical debridement, have the same effect and security as conventional washing, and has certain popularization value
