ObjectiveTo explore the current status of nursing researches about catheter-related infections in recent 5 years in China, and provide reference for further research.MethodsThe China National Knowledge Infrastructure database and Wangfang database were selected to search for literature about catheter-related infections published in recent 5 years in 10 nursing journals of Statistic Source, with the terms of " catheter-related bloodstream infection” or " ventilator-associated pneumonia” or " catheter-related urinary tract infection”. Statistical analysis was conducted.ResultsA total of 216 papers were included. The number of papers was not increased year by year. In terms of the object of study, the studies on ventilator-associated pneumonia were the most, accounting for 71.3%. Only 36.5% of the studies had accurate diagnostic criteria. In terms of the type of study, experimental studies were the most (109 articles). The content was concentrated on the best practice intervention studies (149 articles). The data collection methods gave priority to active surveillance/screening, including 113 articles.ConclusionsThe present focused attention is not enough to the researches about catheter-related infections in nursing field, and rigorous design is lacking in published studies. There are only a few nursing studies about catheter-related infections with high quality and high level of evidence. The quantity and quality of nursing researches about catheter-related infections still need to be improved. Nurses should pay more attention to the control and prevention of catheter-related infections, and should improve their research capacity.
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.
【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.
ObjectiveTo evaluate tip location of peripherally inserted central catheter (PICC) by using the carina as evaluation mark, so as to provide clinical references for blinding manipulation of PICC.
MethodsA retrospective analysis about the effects of tip location of PICC by using the carina as evaluation mark on inpatients with malignant tumour was conducted in tumour centre of the West China Hospital from March 2013 to April 2014. Chest X radiography was applied to evaluate the tip location of PICC. Statistical analysis was performed using SPSS software (version 19.0) and the outcomes were presented by frequency and percentage.
ResultsA total of 612 cases of blinding manipulation of PICC were evaluated, of which, 502 (82%) were located in the central venous and 110 (18%) were located in the noncentral venous. The numbers of those with the catheter tips located in the non-central venous were 38 in the right atrium, 33 in the internal jugular vein, 24 in the innominate vein, 8 in the axillary vein, and 7 in the subclavian vein, respectively.
ConclusionThe effects of blinding manipulation of peripherally-inserted central catheter by using the carina as evaluation mark are relatively good. But it still needs to be improved.
Objective To formulate an evidence-based treatment plan for a child patient with Asymptomatic Wolff-Parkinson-White (WPW) Syndrome. Methods Based on the clinical problems whether the patients with asymptomatic WPW syndrome need prevent catheter ablation or not, we used “asymptomatic WPW syndrome” as the keywords and searched The Cochrane Library (Issue 3, 2007), MEDLINE (1981 to 2007), ACP Journal Club (1991 to 2007), BMJ Clinical Evidence (1999 to 2007) and NGC (1998 to 2007) for systematic reviews, randomized controlled trials (RCTs), controlled clinical trials and treatment guidelines. The methodological quality of the included studies was assessed to identify the current best evidence. Results Two RCTs were retrieved in MEDLINE. The results showed arrhythmic events increased significantly in the high-risk control group than those in the ablation group, and in the patients with multi-pathways than those with only one pathway. Based on the current evidence, integrated with clinical expertise and the patients’ values, the patients underwent electrophysiologic test and the result showed the dominance pathway in the right side and the concealed accessory pathway in the left side. Then prevent catheter ablation was performed, and no cardiovascular complications occurred in the following 12 months, which confirmed that the plan was proved optimal. Conclusion The findings of this study should reassure physicians and parents alike that in the children with the WPW syndrome who are at high risk for arrhythmias, ablation is an appropriate option.
Objective?To investigate the role of low-dose heparin added to total nutrient admixture (TNA) solutions in the prevention of catheter related infections (CRIs). Methods?One-hundred three newborn infants with periph-erally inserted central catheter (PICC) were divided into heparin group (n=63) and control group (n=40). The patients in the heparin group received TNA with 0.5 U/ ml heparin. The patients in the control group received TNA without heparin. We retrospectively analyzed the incidence of CRTs in the two groups. Results?We found that the incidence of CRIs was 0 in the heparin group and 12.5% (5/40) in the control group. The incidence of catheter obstruction was 6.3% (4/63) in the heparin group and 20% (8/40) in the control group. The incidence of catheter-tip colonization was 1.58% (1/40) in the heparin group and 17.5% (7/40) in the control group. The incidences of CRIs, catheter obstruction, and catheter-tip colonization were signiicantly lower in the heparin group than those in the control group (Plt;0.05). Conclusion?TNA solutions with 0.5U/ml heparin have decreased catheter obstruction and CRIs.
ObjectiveTo assess the efficacy and safety of low-(10 mg) and high-dose (20 mg) of recombinant tissue typeplasminogen activator (rt-PA) catheter-directed thrombolysis for lower limb ischemia by using meta-analysis.
MethodsThe literatures of randomized clinical trials (RCT) concerning low-versus high-dose rt-PA catheter-directed thrombolysis for lower limb ischemia study were searched using the national and international electronic databases.The literatures were screened and quality evaluated according to the inclusion and exclusion criteria, and analyzed by using the Cochrane Center the RevMan 5.2 software.
ResultsA total of 4 RCT studies, with a total of 360 patients (192 patients in low dose group and 168 patients in high-dose group) were included.No statistical difference were noted in low-versus high-dose group with regard to ankle-brachial index (RR=0.20, 95%CI=-0.43-0.02, P=0.07), 30 days amputation-free survival (RR=1.00, 95%CI=0.94-1.08, P=0.91), 6 months the probability of restenosis (RR=1.00, 95%CI=0.60-1.67, P=1.00), and the incidence of groin hematoma (< 5 cm, RR=1.24, 95%CI=0.56-2.77, P=0.59).But the incidence of bleeding and the incidence of stress ulcer in low-dose group were lower than those in high-dose group (RR=2.38, 95%CI=1.10-5.15, P=0.03;RR=2.49, 95%CI=1.21-5.13, P=0.01).
ConclusionTwo doses of rt-PA treatment of limb ischemia similar efficacy, but the incidence of low-dose regimen of complications is significantly lower than the high dose regimen.
Objective
To discuss the effect of monitoring-training-planning (MTP) intervention model on the prevention and control of catheter–associated urinary tract infection (CAUTI) in Intensive Care Unit (ICU).
Methods
Patients with indwelling catheter from departments with ICU (ICU, ICU of the Department of Neurosurgery, ICU of the Department of Neurologic Medicine) between 2014 and 2015 were included in this study. Based on the inclusion criteria, target monitoring indicators were set in accordance with Hospital Infection Monitoring Norms. A total of 493 patients with indwelling catheters from January to December 2014 were subjected to target surveillance, and were used as baseline for the study. A total of 529 patients with indwelling catheters from January to December 2015 were treated with MTP intervention. The occurrence of indwelling catheter–associated urinary tract infections in the intensive care unit was compared before and after intervention.
Results
The incidence of indwelling catheter-associated urinary tract infections before and after MTP intervention were different, and the difference was statistically significant (P<0.05).
Conclusion
MTP intervention model can effectively prevent and reduce indwelling catheter-associated urinary tract infections in ICU.
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.
ObjectiveTo reduce the incidence of peritoneal dialysis (PD) catheter complications through a continuous quality improvement (CQI) process.
MethodsTwenty-nine patients with catheters inserted (from January 2011 to March 2011) before CQI, and another 41 patients with catheters inserted (between April 2011 and January 2012) after CQI were observed and analyzed. The possible causes of complications of catheter were summarized, and then on the basis of that, a PDCA four-step (plan-do-check-act) method was designed with a view to reducing the incidence of postoperative complications.
ResultsPD catheter dysfunction decreased from 6.90% to 2.44%. The incidence of leakage decreased from 44.83% to 9.76%.
ConclusionCQI is a useful method to reduce the incidence of postoperative complications of PD catheter in peritoneal dialysis.
