目的通过调查分析神经外科重症监护病房(NICU)医院感染发生情况、感染部位病原菌的构成及感染影响因素,以寻求有效的预防措施。方法通过自制调查表收集贵州省铜仁医院2008年1月至2010年5月362例NICU患者的临床资料,包括患者年龄、感染部位、感染诱发因素、病原菌种类及其耐药性、可能的影响因素等并作分析。结果医院感染发生率为18.5%,8.2例/1000床日,高于同期医院其他科室的感染率;发生医院感染的主要疾病为中枢神经系统炎症和医院获得性肺炎,分别为58.2%和34.3%;共检出病原菌220株,其中革兰阴性杆菌103株(46.8%),革兰阳性球菌96株(43.6%),真菌21株(9.5%)。金葡菌除对万古霉素呈敏感外.对其余测试抗菌药物的耐药率均高于80.0%,大肠埃希菌除对亚胺培南耐药率低,为1.1%外,对其余测试抗菌药物的耐药率均高于20.0%。单因素分析和多因素逐步logistic回归分析发现,患者发生医院感染与住院时间、是否机械通气、侵袭性操作、H2受体拮抗剂的使用有关。结论NICU患者中医院感染发生率高,感染部位集中,影响因素复杂,应采取综合措施控制医院感染,加强病室管理,在治疗及护理过程中应特别注意对呼吸系统和泌尿系统的无菌操作,合理使用抗生素,监测病原菌及其耐药性,减少住院期间的交叉感染等。 相似文献

Purpose
Patients may be at high risk for hemodynamic instability in the early postoperative period, with subsequent poor cerebral perfusion and the development of postoperative cerebral oxygen desaturation events (CDEs). Intraoperative CDEs have been associated with postoperative adverse events. However, none of these studies examined the incidence of early postoperative cerebral desaturations. This study was designed to identify the incidence of CDEs (defined as a decrease in SctO2 to less than 60% for at least 60 seconds) in the immediate postoperative period following cardiac surgery.Methods
Fifty-three moderate to high-risk patients undergoing elective cardiac surgery were enrolled in this observational study. Cerebral oximeter monitors were placed on all patients prior to induction of anesthesia and remained in place for 6 hours or until the patients were extubated postoperatively, whichever occurred first. Data were recorded from the cerebral oximeter, physiologic monitor and ventilator during the study period. Data were analyzed to identify the incidence of early postoperative CDEs, as well as association with subsequent clinical events.Results
The incidence of early postoperative CDEs was 53%. Sixty-four percent of these CDEs lasted for more than 1 hour. Patients with postoperative CDEs were more likely to have had intraoperative CDEs (P < 0.0001). Five out of 28 patients who experienced CDEs in the intensive care unit died while none of the patients without postoperative CDEs died (P = .053).Conclusion
A high incidence of CDEs (53%) was found in the early post-cardiac surgery period. Larger studies are needed to determine whether postoperative CDEs are correlated with various physiologic events or are associated with adverse patient outcomes. 相似文献12.

Chromobacterium violaceum is sensitive to temperature and the infection is usually confined to tropical or subtropical regions. Since Japan has a warm climate, C. violaceum has been scarcely isolated from clinical specimens. With global warming, however, the geographical distribution of C. violaceum infection is likely to change. We report two cases of C. violaceum nosocomial pneumonia that occurred at an intensive care center in Japan. C. violaceum was first detected from a patient in the same center as a pathogenic organism of pneumonia. Later, the organism was isolated from sputum and a ventilator circuit tube of another patient in the center. The two patients were admitted to the center in nearby beds for several days. All of the pathogens were confirmed to be C. violaceum by the nucleic acid sequence of the 16S rRNA gene and were proven to be genetically identical organisms by pulsed field gel electrophoresis. Both patients were managed with well-humidified and heated oxygen using a venturi mask and ventilator to promote excretion of sputum. It was thought that the medical respiratory care devices that provide a humid and warm environment, an optimal condition for proliferation of C. violaceum, can contribute to C. violaceum infection in a hospital environment. 相似文献

Objective To determine epidemiology and risk factors for nosocomial infections in intensive care unit (ICU).Design Prospective incidence survey.Setting An adult general ICU in a university hospital in western Turkey.Patients All patients who stayed more than 48 h in ICU during a 2-year period (2000–2001).Measurements and results The study included 434 patients (7394 patient-days). A total of 225 infections were identified in 113 patients (26%). The incidence and infection rates were 56.8 in 1000-patient days and 51.8%, respectively. The infections were pneumonia (40.9%), bloodstream (30.2%), urinary tract (23.6%) and surgical site infections (5.3%). Pseudomonas aeruginosa (22.6%), methicillin-resistant Staphylococcus aureus (22.2%) and Acinetobacter spp. (11.9%) were frequently isolated micro-organisms. Median length of stay with nosocomial infection and without were 13 days (Interquartile range, IQR, 20) and 2 days (IQR, 2), respectively (P<0.0001). In logistic regression analysis, mechanical ventilation [odds ratio (OR): 16.35; 95% confidence interval (CI): 8.26–32.34; P<0.0001), coma (OR: 15.04; 95% CI: 3.41–66.33; P=0.0003), trauma (OR: 10.27; 95% CI: 2.34–45.01; P=0.002), nasogastric tube (OR: 2.94; 95% CI: 1.47–5.90; P=0.002), tracheotomy (OR: 5.77; 95% CI: 1.10–30.20; P=0.04) and APACHE II scores 10–19 (OR: 10.80; 95% CI: 1.10–106.01; P=0.04) were found to be significant risk factors for nosocomial infection. Rate of nosocomial infection increased with the number of risk factors (P<0.0001). Mortality rates were higher in infected patients than in non-infected patients (60.9 vs 22.1%; P<0.0001).Conclusion These data suggest that, in addition to underlying clinical conditions, some invasive procedures can be independent risk factors for nosocomial infection in ICU. 相似文献

Background: Changes in patient profile, and in the health care environment, altering socioeconomic conditions and advances in science and information technology challenge the nursing profession, in particular intensive care nursing. All these changes will undoubtedly affect the way we will practice in the (near) future. A comprehensive understanding of these factors is therefore essential if nursing is to meet the challenges presented by tomorrow's critical care environment. Precisely because of the often expensive high‐tech evolutions that have occurred at a rapid pace and are to be further expected, a continued focus on the basics of nursing, the core role of care, as well as maintaining confidence in the capacity to deliver safe, high‐quality, and evidence‐based patient care will increasingly be a challenge to critical care nurses. In particular, basic nursing skills and knowledge remain a key prerequisite in the prevention of nosocomial infections, which is a continuing major complication and threat to intensive care unit patients. However, critical care nurses' knowledge about the evidence‐based consensus recommendations for infection prevention and control has been found to be rather poor. It has nevertheless been demonstrated that a meticulous implementation of such preventive bundles may result in significantly better patient and process outcomes. Moreover, many preventive strategies are considered to be easy to implement and inexpensive. As such, a first and critical step should be to increase critical care nurses' adherence to the recommendations of the Centers for Disease Control and Prevention. Aim: In this article, an up‐to‐date assessment of evidence‐based recommendations for the prevention of nosocomial infections, with special focus on catheter‐related bloodstream infections and strategies relevant for nurses working in critical care environments, will be provided. Additionally, we will detail on a number of approaches advocated to translate the internationally accepted consensus recommendations to the needs and expectations of critical care nurses, and to consequently enhance the likelihood of successful implementation and adherence. These steps will help critical care nurses in their striving towards excellence in their profession. Summary: Intensive care nurses can make a significant contribution in preventing nosocomial infections by assuming full responsibility for quality improvement measures such as evidence‐based infection prevention and control protocols. However, as general knowledge of the preventive measures has been shown to be rather poor, nurses' education should include supplementary support from evidence‐based recommendations. 相似文献
