【摘要】：目的观察髋关节置换术后医院感染患者下肢微循环与微生物学检测结果,以为髋关节置换术后医院感染的预防控制与诊治提供依据。方法选取2015年1月-2016年7月医院诊治24例髋关节置换术后医院感染患者为观察组,同时选取24例髋关节置换术后未发生感染患者为对照组,然后检测及比较两组的下肢微循环指标,并比较不同感染部位患者的下肢微循环指标,同时检测及比较观察组患者中的病原菌情况。结果观察组足甲襞微循环加权积分襻周积分、管襻形态积分及总积分分别为(1.10±0.12)、(1.35±0.14)及(2.93±0.21),其显著地高于对照组(0.59±0.05)、(0.80±0.07)及(1.87±0.13),其他足甲襞微循环指标均低于对照组,手术部位感染患者足甲襞微循环指标差于其他部位感染者,24例感染患者共检出39株病原菌,革兰阳性菌所占比例明显高于革兰阴性菌,差异均有统计学意义(P0.05)。结论髋关节置换术后医院感染患者下肢微循环处于较差的状态,而革兰阳性菌在此类患者的检出率相对较高,应给予充分的重视与干预。
[Abstract]:Objective to observe the results of lower extremity microcirculation and microbiology in patients with nosocomial infection after hip arthroplasty, so as to provide evidence for the prevention, control, diagnosis and treatment of nosocomial infection after hip arthroplasty. Methods from January 2015 to July 2016, 24 patients with nosocomial infection after hip replacement were selected as observation group and 24 patients without infection after hip replacement as control group. Then the indexes of microcirculation of lower extremity were detected and compared between the two groups, and the indexes of microcirculation of lower extremities in patients with different infection sites were compared. At the same time, the pathogens of the patients in the observation group were detected and compared. Results the circumference integral, the shape integral and the total integral were (1.10 卤0.12), (, 1.35 卤0.14) and (2.93 卤0.21), respectively, in the observation group, which were significantly higher than those in the control group (0.59 卤0. 05). (0.80 卤0.07) and (1.87 卤0.13), other microcirculation indexes of foot nail fold were lower than those of control group. The index of foot nail fold microcirculation in patients with operative site infection was worse than that in other infected patients. 39 strains of pathogenic bacteria were detected in 24 cases of infection. The proportion of Gram-positive bacteria was significantly higher than that of Gram-negative bacteria (P0.05). Conclusion the lower extremity microcirculation of the patients with nosocomial infection after hip arthroplasty is in poor condition, and the detection rate of Gram-positive bacteria in these patients is relatively high, which should be paid more attention and intervention.
