Objective To explore the risk factors of catheter-associated bloodstream infections ( CRBSI) in intensive care unit ( ICU) of primary hospital. Methods A total of 623 patients with central venous catheters were recruited in the study. 60 of themsuffered fromCRBSI served as an observation group and other 563 cases without CRBSI served as control. Univariate analysis was used to scan possible risk factors. Then logistic regression analysis was used to exclude the confounding factors. Results The overall incidence rate of CRBSI was 9. 63% ( 60 /623) . There were significant differences in APACHE score, type of catheter, location of catheter, duration of central venous catheter, intravenous nutrition, use of steroid, times of intubation, urgent intubations, nutritional status, diabetes, and MODS between the two groups. Logistic regression analysis revealed that higher APACHE score, double-lumen catheter, femoral vein catheter, catheter indwelling more than two weeks, intravenous nutrition, intubation more than 2 times, and emergency intubation were risk factors of CRBSI. Conclusions Higher APACHE score, double-lumen catheter, femoral vein catheter, catheter indwelling more than two weeks, intravenous nutrition, intubation more than 2 times, and emergency intubation were major risk factors of CRBSI in ICU of primary hospital.
【Abstract】Objective To investigate the diagnostic and therapeutic value of selective angiography and embolization treatment in massive biliary hemorrhage in emergency. Methods Eleven cases of massive biliary bleeding were selectively angiographied and embolized with thread segment and gelatin sponge grain by Seldinger technique in emergency. Results Massive biliary bleeding in this series included bleeding after biliary surgery (7), post-laparoscopic cholecystectomy bleeding (1), bleeding from traumatic injury to liver (1), and rupture of huge hepatic cancer (2). There were 9 cases with abnormal angiographic findings including contrast medium leakage (9), tumor vessels and tumor tissue staining (2) and signs of pseudo-aneurysm formation (4). All the bleedings were stopped after emergency intervention but 2 cases with recurrent massive bleeding after 48 hours. Conclusion Emergency trans-catheter embolization treatment is an effective and safe method for biliary massive hemorrhage. It is also important to keep the biliary tract unobstructed.
Objective To find the most effective treatment for a patient with difficult selective biliary cannulation (DSBC) during endoscopic retrograde cholangiopancreatography (ERCP) by EBM practice. Methods Evidence was retrieved from The Cochrane Library (Issue 1, 2010), ACP online, NGC (1998 to June 2010), PubMed (1950 to June 2010), and CBM (1994 to June 2010). The collected evidence was then graded. Results After preliminary research, we identified 18 relevant articles. The evidence showed that pre-cutting technique could increase cannulation success rates in DSBC and was safe, effective, and time-saving for an experienced endoscopist. Pancreatic duct occupation was easier to perform than pre-cutting technique and could also increase selective cannulation success rates in DSBC. According to the evidence, together with endoscopist’s experience and the preference of the patient and his family, needle-knife precut papillotomy was performed. Successful selective biliary cannulation was accomplished after pre-cutting. Conclusion The current evidence suggests that pre-cutting technique and pancreatic duct occupation could increase selective cannulation success rates in DSBC. Patients’ condition and endoscopist’s experience should be considered properly before the operation.
ObjectiveTo investigate the clinical efficacy of catheter directed thrombolysis (CDT) through three different approaches combined with iliac venous endovascular therapy for acute deep venous thrombosis (DVT) complicated with Cockett syndrome of the lower extremities. MethodThe clinical data of 87 patients with CDT through three different approaches (small saphenous vein group, popliteal vein group, and posterior tibial vein group) combined with iliac venous endovascular therapy for DVT complicated with Cockett syndrome of the lower extremities were analyzed retrospectively. ResultsThe lower extremity swelling of all the patients were disappeared obviously within 72 h after surgery, there was no death related surgery and pulmonary embolism. The limb edema reduction rates had no significant differences among the small saphenous vein group, popliteal vein group, and posterior tibial vein group﹝(77±13)% versus (82±12)% versus (77±18)%, P > 0.05﹞. The recanalization rates of thrombolysis had no significant differences among the above three groups﹝(86.5±10.6)% versus (92.0±7.7)% versus (87.3±7.8)%, P > 0.05﹞. The time required for the cannulation in the posterior tibial vein group was significantly shorter than that of the small saphenous vein group or popliteal vein group﹝(15.14±3.62) min versus (32.62±9.36) min or (42.79±13.30) min, P < 0.01﹞. All the patients were performed by balloon dilatation and iliac vein stenting. Eighty-seven cases were followed-up for 1-24 months, the primary patency rate of iliac venous was 100%. ConclusionsCDT with iliac venous endovascular therapy is an effective method in treatment of acute DVT with Cockett syndrome. CDT through posterior tibial vein is an easier and effective method with less complications and time. This way could be acceptable in basal hospital.
ObjectivesTo systematically evaluate the efficacy and safety of dabigatran vs. rivaroxaban for perioperative anticoagulation in the ablation of nonvalvular atrial fibrillation. MethodsPubMed, EMbase, Web of Science, The Cochrane Library, WanFang Data, CNKI and VIP databases were electronically searched to collect cohort studies on the efficacy and safety of dabigatran vs. rivaroxaban for perioperative anticoagulation in the ablation of nonvalvular atrial fibrillation from inception to July 1st, 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by RevMan 5.3 and Stata 12.0 software. ResultsA total of 12 cohort studies involving 4 051 patients were included. The results of meta-analysis showed that: there were no differences in the rate of thromboembolic (OR=0.92, 95%CI 0.36 to 2.35, P=0.86), ischemic stroke (OR=1.15, 95%CI 0.22 to 6.07, P=0.87), major bleeding (OR=0.84, 95%CI 0.43 to 1.66, P=0.61), minor bleeding (OR=0.90, 95%CI 0.60 to 1.34, P=0.60) and pericardial tamponade (OR=1.05, 95%CI 0.45 to 2.47, P=0.90) between dabigatran and rivaroxaban groups. ConclusionsCurrent evidence shows that the efficacy and safety of dabigatran vs. rivaroxaban for perioperative anticoagulation in the ablation of nonvalvular atrial fibrillation are similar. Due to limited quality and quantity of the included studies, more high quality studies are required to verify the above conclusion.
Objective To systematically evaluate the influence of PICC (peripherally inserted central catheter) ultrasound guidance on success rates and incidences of complications of elbow catheterization. Methods The Cochrane Library (Issue 3, 2012), Library of JBI evidence-based nursing center, MEDLINE, EMbase, CBM, VIP, CNKI and WanFang Data were searched for relevant studies to influence on success rates of puncture and catheterization and complications from upper arm placement of PICC ultrasound guidance as well as conventional PICC placement from inception to March, 2012. The data were extracted according to the inclusion and exclusion criteria by two reviewers, the quality of included studies was also evaluated. Meta-analysis was conducted using RevMan 5.1, or only descriptive analysis was conducted instead. Results Eleven randomized controlled trials, five clinical controlled trials and four cohort studies were included, involving 4 052 patients. The results of meta-analysis showed that, upper arm placement of PICC ultrasound guidance combined with modified Seldinger technique was associated with significantly higher one-time success rates of puncture and catheterization than conventional PICC placement below the elbow, with significant differences (OR=4.71, 95%CI 1.97 to 11.28, P=0.000 5; OR=8.63, 95%CI 1.92 to 38.82, P=0.005). Conventional elbow catheterization had a significantly higher incidence of phlebitis than catheterization on the elbow that under the guidance of PICC ultrasound and modified Seldinger technique (OR=0.13, 95%CI 0.08 to 0.21, Plt;0.000 01). Conclusion Elbow catheterization under the guidance of PICC ultrasound combined with modified Seldinger technique has an obvious advantage in improving the success rates of puncture and catheterization and reducing the incidence of complications, compared with conventional elbow catheterization.
Abstract： Objective To analyze clinical outcomes of interventional therapy for common congenital heart diseases （CHD）. Methods We retrospectively analyzed the clinical records of 57 patients with CHD who underwent catheter interventional therapy in People’s Hospital of Deyang City between March 2009 and January 2012. There were 31 male patients and 26 female patients with their mean age of 29.4±3.5 years（ranging from 1.5 to 75.0 years）. There were 21 patients with patent ductus arteriosus （PDA）, 12 patients with ventricular septal defect （VSD）, and 20 patients with atrial septal defect（ASD）；and 2 patients with VSD plus ASD, 1 patient with VSD plus PDA, and 1 patient with ASD plus PDA. Occluder and supplying system made in China were used in the interventional therapy. For the patients with ASD plus PDA, PDA was blocked before ASD；for the patients with VSD plus PDA, PDA was blocked before VSD；and for the patients with VSD plus ASD, VSD was blocked before ASD. Results The duration of interventional therapy ranged from 30 to 90 minutes. The success rate of operation was 98.3%（56/57）. Operation was given up in an old female patient with ASD and chronic obstructive pulmonary disease because of pulmonary hypertension. The hospital stay was 3 -7 days. All the patients were followed up at the outpatient department for 1 month to 2 years by color Doppler echocardiogram, chest X-ray and electrocardiograph, and no complication occurred during follow-up. Conclusion With complete understanding of surgical indications and strict compliance with procedures, catheter interventional therapy is safe, minimal invasive, and effective in CHD treatment.
ObjectiveTo investigate the incidence and trendency of healthcare-associated infections (HAIs) in a pediatric intensive care unit (ICU) of a hospital, identify the main objectives of infection control, and formulate corresponding preventive and control measures.MethodsA prospective targeted monitoring method was adopted to investigate HAIs in the pediatric ICU of a hospital from January 2013 to December 2018.ResultsFrom January 2013 to December 2018, the number of target ICU patients was 11 898, the number of patient-days was 55 159; 226 HAIs occurred, the HAI case rate was 1.90%, the incidence of HAI per 1 000 patient-days was 4.10‰, and the adjusted incidence of HAI per 1 000 patient-days was 1.21‰. The main infection site was respiratory tract [83 cases (36.7%)], with ventilator-associated pneumonia in 73 cases (32.3%); secondly, 69 patients (30.5%) had bloodstream infection, among which 48 (21.2%) had non-catheter-related bloodstream infection.ConclusionHospital targeted monitoring is helpful to grasp the situation and trend of HAIs, define the main target of infection control, and formulate corresponding preventive and control measures, which can effectively reduce the incidence of HAIs.
ObjectivesTo systematically review the efficacy and safety of catheter-directed thrombolysis (CDT) versus anti-coagulation (AC) for deep vein thrombosis (DVT). MethodsWe searched PubMed, EMbase, The Cochrane Library, Web of Science, WanFang Data and CNKI databases to collect randomized clinical trials (RCTs) about CDT versus AC for DVT from inception to March 2018. Two reviewers independently screened literature, extracted data and evaluated the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.3 software. ResultsA total of 5 RCTs and 989 patients were included. Meta-analysis showed that there was no significant difference between the two group in incidence of post-thrombotic syndrome (RR=0.73, 95%CI 0.49 to 1.09, P=0.13), iliofemoral venous patency rate (RR=2.57, 95%CI 0.59 to 11.24, P=0.21), bleeding (RR=2.03, 95%CI 0.50 to 8.28, P=0.32), severe bleeding (RR=1.77, 95%CI 0.91 to 3.42, P=0.09) and recurrence rate of venous thromboembolism (RR=1.00, 95%CI 0.42 to 2.36, P=0.99). However, the incidence of moderate-severe PTS decreased in CDT group was lower than that in the control group (RR=0.70, 95%CI 0.53 to 0.92, P=0.01). ConclusionsCompared with the control group, catheter-directed thrombolysis does not reduce the incidence of PTS and VTE recurrence rate, cannot improve the long-term patency of the iliofemoral vein, yet can prevent the occurrence of moderate to severe PTS. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
ObjectiveTo investigate the species and resistance phenotypes of the pathogens causing catheter-associated urinary tract infection (CAUTI) in critically ill patients in West China Hospital of Sichuan University, and to provide the basis for the prevention and treatment of this kind of infection. MethodsThe clinical data and findings of the laboratory examination of the patients, who were admitted to intensive care units and suffered from CAUTI in our hospital during January 2012 to December 2014, were retrospectively analyzed. The pathogens isolates from the urine specimens of the patients with CAUTI and their resistance phenotypes were analyzed. ResultsThree hundred and seventy patients suffering from CAUTI were included in this study. Five hundred and seventeen strains of pathogens were isolated from the urine specimens of these patients, including 222 isolates (42.9%) of fungus, 181 isolates (35.0%) of gram negative bacteria, and 114 isolates (22.0%) of gram positive bacteria. In terms of species distribution, Candida albicans (105 isolates, 20.3%), C.glabrata (78 isolates, 15.1%) and C.glabrata (30 isolates, 5.8%) were the predominant fungus. Among the gram negative bacteria, Escherichia coli (81 isolates, 15.7%), Klebsiella pneumoniae (37 isolates, 7.2%), and Acinetobacter calcoaceticus-baumannii complex (23 isolates, 4.4%) were the main species. Enterococcus faecium (79 isolates, 15.3%) and E.faecalis (13 isolates, 2.5%) were the frequently isolated gram positive bacteria. Analysis of the resistance phenotype showed that the resistance rates to itraconazole, voriconazole and fluconazole of Candida spp. were above 10%. Thirty percent of the isolates of E.coli and K.pneumoniae, and 60% of the isolates of A.calcoaceticus-Baumannii complex were resistant to many of the regular antibiotics. Imipenem resistance rate of A.calcoaceticus-Baumannii complex was 60.8%. Sixty percent of the isolates of E.faecium and E.faecalis were resistant to many of the regular antibiotics. The vancomycin-resistant isolates accounted for 16.5% of E.faecium and 31.0% of E.faecalis. ConclusionCandida species are the major pathogens for CAUTI in critically ill patients in our hospital and show the resistance to azoles. We should focus on the drug resistance of gram negative bacteria and gram positive bacteria. The rational use of antibiotics and application of effective infection control measures are important to decrease the CAUTI.
