Objective To study the catheter-related infection (CRI) in cancer patients treated with central venous catheterization. Methods A prospective study with 196 cancer patients was conducted to analyze the types of catheter-related infection and pathogen, as well as the relationship between CRI and the following factors: insert location, gender, age, remained time, or bone marrow suppression. Results Of the total 196 cases, 16 cases were diagnosed as CRI and the CRI rate was 8.2%. The types of CRI were five cases of pathogen colonization, four cases of insert location infection and seven cases of catheter-related bloodstream infection. Of the total 244 specimens, 20 were positive including 7 pathogenic bacteria in either Gram positive or Gram negative types, the dominating pathogens were staphylococcus aureus, staphylococcus epidermidis, acinetobacter baumannii and klebsiella pneumoniae. CRI was related to both insert location and age which were both the independent risk factors. Conclusion The concept of prevention should be set up, and the comprehensive measures should be taken to reduce CRI, such as choosing an appropriate insert location and complying with a strict catheter insert standard.
Objective To investigate the risk factors of central line-associated bloodstream infection (CLABSI) and provide clinical guidance for reducing the incidence of CLABSI. Methods The clinical data of patients with central venous catheter catheterization in Sichuan Provincial People’s Hospital between January 2018 and December 2021 were retrospectively collected. According to whether CLABSI occurred, the patients were divided into CLABSI group and non-CLABSI group. The data of patients were analyzed and the risk factors of CLABIS were discussed. Results A total of 43 987 patients were included. Among them, there were 63 cases in the CLABSI group and 43924 cases in the non-CLABSI group. The incidence of CLABSI was 0.18/1 000 catheter days. Multivariate logistic regression analysis showed that admission to intensive care unit (ICU) [odds ratio (OR)=74.054, 95% confidence interval (CI) (22.661, 242.005), P<0.001], hemodialysis [OR=4.531, 95%CI (1.899, 10.809), P=0.001] and indwelling catheter days [OR=1.017, 95%CI (1.005, 1.029), P=0.005] were independent risk factors for CLABSI. A total of 63 strains of pathogenic bacteria were isolated from the 63 patients with CLABSI. Among them, 28 strains of Gram-positive bacteria, 25 strains of Gram-negative bacteria and 10 strains of Candida. Conclusions Admission to ICU, hemodialysis and long-term indwelling catheter are independent risk factors for CLABSI. The prevention and control measures of CLABSI should be strictly implemented for such patients to reduce the risk of infection.
ObjectiveTo explore the trend and hotspots of research in the field of peripherally inserted central catheter (PICC), so as to provide a reference for clinical nursing and nursing research in the field of vascular access in China.MethodsAll PICC-related articles from 1806 to November 22nd, 2018 were searched in the Foreign Medical Retrieval System. The publication amount, year of publication, language, country, journals and impact factor, high-yield authors and high-frequent medical subject headings (MeSH) of the PICC-related articles were analyzed by using frequency, cumulative frequency, and constituent ratio.ResultsA total of 1 550 articles were included. They were published in 586 journals, of which 393 were included in Science Citation Index. English was the dominant publication language, and the top high-yield country was the United States. The top 16 high-yield authors published 199 articles, the top 3 of whom all had published co-operative papers, ranging from 1 article to 19 articles. The top 3 high-frequent MeSHs were “Catheters, Indwelling” “Catheterization, Central Venous” “Central Venous Catheter”.ConclusionsPICC has become a hotspot in clinical research, and the publication amount of relative literature has increased rapidly since 2000. Chinese scholars should improve their English and carry out multi-center cooperative research to improve the quality of PICC-related literature.
目的 了解成都市肿瘤科医护人员经外周静脉留置中心静脉导管术（PICC）认知现状，为今后开展PICC相关知识培训提供科学依据。 方法 2009年12月－2010年1月采用自行设计的问卷对成都市5家三甲医院的肿瘤科医护人员309名（医生134名，护士175名）进行PICC认知态度现状调查。 结果 成都市三甲医院肿瘤科医护人员PICC认知呈中等偏低的水平，护士PICC知识的掌握高于医生（P＜0.05），护士PICC态度得分优于医生（P＜0.05）。94.84%的医护人员知道PICC技术；只有8.38%的肿瘤科医护人员接受过PICC专业培训。不同文化程度、年龄、工龄、职业与PICC认知之间的差异存在统计学意义（P＜0.05）。 结论 三甲医院肿瘤科医护人员对PICC技术有一定的了解，但总体认知仍有待提高，需加强PICC相关知识培训，进一步提高医护人员PICC认知水平，以利于肿瘤专科开展PICC技术，促进肿瘤护理的专业化发展。
