目的了解神经外科重症病房鲍曼不动杆菌临床分布特点及影响因素,为医院感染控制提供参考。方法前瞻性监测神经外科重症病房患者600例,收集鲍曼不动杆菌感染情况。结果 43例患者感染鲍曼不动杆菌,感染率为7.17%;共检测72株鲍曼不动杆菌,以气管切开患者下呼吸道痰液标本最多,占44.44%;急诊、留置引流管、有脑脊液漏、手术次数、术中失血量、有基础疾病(高血压、糖尿病等)、使用3种抗生素时间≥14d,可增加鲍曼不动杆菌感染率(P0.05,P0.01)。结论鲍曼不动杆菌已成为神经外科重症病房医院感染病原菌,主要引起气管切开下呼吸道感染。需加强对易感人群如急诊、留置引流管、有脑脊液漏及基础疾病患者防护,尽可能降低患者术中出血量及抗生素使用种类与时间,以减少鲍曼不动杆菌感染的发生。 相似文献

BACKGROUND:Low power microwave irradiation has been shown to promote the healing of fractures with internal fixation; however, its action mechanisms on the skeletal muscle around the fracture site are unclear.
OBJECTIVE:To study the effects of low power microwave irradiation (20 W) on the proliferation ability of skeletal muscle satellite cells in a rabbit model of femoral fracture with internal fixation.
METHODS:Forty male New Zealand rabbits were used to establish femoral fracture followed by internal fixation models, and then were equally randomized into spontaneous recovery and microwave treatment groups. Low power microwave irradiation (20 W) was given for 30 consecutive days in the microwave treatment group on day 4 after modeling, while no microwave irradiation was given in the spontaneous recovery group. Rabbit thigh muscles adjacent to the implant were obtained to isolate skeletal muscle satellite cells. Immunohistochemical staining, hematoxylin-eosin staining and quantitative RT-PCR were used to evaluate the ability of the proliferation and differentiation of skeletal muscle satellite cells.
RESULTS AND CONCLUSON: Hematoxylin-eosin staining showed that there was no significant difference in the morphology and histology of skeletal muscle tissues between the spontaneous recovery and microwave treatment groups. However, the relative mRNA expression of MyoG in the cultured skeletal muscle satellite cells in vitro and the number of α-sarcometric actin-postive cells in the microwave treatment group were significantly increased compared with the spontaneous recovery group (P < 0.05). The proliferative ability of skeletal muscle satellite cells was inhibited at the early stage, but not at the later stage. Our results suggest that low power microwave irradiation (20 W) can promote the proliferation and differentiation of skeletal muscle satellite cells around the implant in a rabbit model of femoral fracture with internal fixation, and thereby confirm the efficacy and safety of low power microwave irradiation for the internal fixation of fractures.
