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.
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.
ObjectiveTo evaluate the safety and efficacy of second central venous catheterization in tunnel cuffed dialysis catheter (TCC) dysfunction with fibrin sheath.MethodA total of 14 maintenance hemodialysis patients who required second central venous catheterization were enrolled in West China Hospital of Sichuan University from June 2016 to June 2017 and the clinical information and procedure-related complications were recorded.ResultsAll of the 14 patients were successfully performed with second central venous catheterization, of whom 4 cases had superior vena cava cannulation, 7 cases had right brachiocephalic vein cannulation, 2 cases had internal jugular vein cannulation, and 1 case had external jugular vein cannulation. No procedure-related major complication occurred. During the follow-up, catheter malfunction occurred in 2 cases, which improved by urokinase seal and catheter change, respectively. The rest patients’ catheter function remained normal.ConclusionsWith increasing difficult to construction and maintenance of vascular access, preservation of central vein resource is of high importance. For patients with TCC dysfunction with fibrin sheath, second central venous catheterization based on percutaneous brachiocephalic vein or superior vena cava cannulation is a safe and effective method to establish the lifeline for hemodialysis patients.
ObjectiveTo investigate the therapeutic evaluation of catheter-directed thrombolysis combined with multiple minimally invasive techniques of endovascular in the treatment of lower extremity atherosclerotic occlusive disease (ASO). MethodsClinical data of 64 ASO patients who were treated in our hospital from June 2011 to October 2014 were analyzed retrospectively. These patients were divided into two groups according to the therapies:33 patients were treated by catheter-directed thrombolysis combined with multiple minimally invasive techniques of endovascular (combination group), and the other 31 patients were only treated by multiple minimally invasive techniques of endovascular (intervention group). Comparison of the clinical indexes was performed between the 2 groups, including vascular patency rate, stent implantation rate, operation time, ankle-brachial index (ABI), saturation of blood oxygen (SO2) of toes, temperature of foot skin, amputation rate, and hospitalization expense. ResultsIn the same group (combination group and intervention group), compared with the time point of before operation, the clinical indexes of the ABI, SO2 of toes, and temperature of foot skin were higher after operation (P<0.05). At the same time point of before or after operation, there were no significant difference between the 2 groups in ABI, SO2 of toes, and temperature of foot skin (P>0.05). The vascular patency rate of combination group was higher than that of intervention group[97.0% (32/33) vs. 83.9% (26/31)], P<0.05. But the stent implantation rate[18.2% (6/33) vs. 64.5% (20/31)], amputation rate[3.0% (1/33) vs. 16.1% (5/31)], operative time[(2.0±0.5) h vs. (4.0±1.1) h], and hospitalization expense of patients who got successful limb salvage[(8 500±1 200) yuan vs. (34 000±2 100) yuan] of combination group were all lower or shorter than those of intervention group (P<0.05). After operation, there were no complication happened in the patients who got successful limb salvage of combination group (n=32) and intervention group (n=26). In postoperative 6 months, the lower extremity arteries in patients who got successful limb salvage of combination group and intervention group were all examined by color ultrasonography, and they were unblocked. The lower extremity arteries of the patients with stent implantation in the 2 groups suffered with no obvious stenosis or occlusion. ConclusionsCatheter-directed thrombolysis combined with multiple minimally invasive techniques of endovascular can become one of the surgical treatment methods for ASO, which characterized by minimally invasive operation, effective treatment, and low cost.
ObjectiveTo assess the therapeutic effect of catheter thrombolysis combined with inferior vena cava (IVC) filter placement in treatment of deep venous thrombosis (DVT) complicated with floating IVC thrombus. MethodsThe clinical data of 16 patients with DVT complicated with floating IVC thrombus from July 2013 to November 2014 in this hospital were collected. These patients were treated with the catheter thrombolysis combined with IVC filter placement, the IVC filter was placed via jugular vein, the catheter thrombolysis was performed by the side of the small saphenous vein, the amount of urokinase was (60-80) ×104 U/d. Results①The floating IVC thrombi of 13 patients were disappeared following catheter thrombolysis combined with IVC filter placement therapy, a small amount of visible thrombi were adhered on the recycled IVC filter, the lower limb swelling was relieved, the IVC could effectively open.②The IVC filters of 2 patients could not be recycled due to the adhesion of floating IVC thrombus and lumen of IVC resulting in luminal stenosis.③The floating IVC thrombus of 1 patient was disappeared, the IVC filter could not be recy-cled due to a large of thrombi adhered on the IVC filter. The lower limb swelling was slowly relieved. The complications such as severe pulmonary embolism didn't happen in all the patients during treatment and following-up. ConclusionThe limited data preliminarily shows that it is an effective and safe method by catheter thrombolysis combined with IVC filter placement in treatment of DVT complicated with floating IVC thrombus.
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.
Peripherally inserted central catheter (PICC) is widely used as an intravenous therapy pathway, and catheter occlusion is one of the most common complications during the use of PICC. Catheter occlusion may lead to extubation or re-catheterization, which may generate prolonged hospital stay and increased medical costs, thus affecting the implementation of treatment and patient prognosis. The prevention and treatment of occlusion are of great significance. Daily maintenance and nursing operations should be complete, standardized and implemented in place. Evidence-based standard procedures should be established to meet the needs of clinical work. This consensus follows the methods and principles provided in the WHO guidelines formulation manual, and forms a systematic and standardized clinical practice process, including PICC patency assessment, catheter occlusion degree and type assessment, risk factor prevention, blockage management, etc. The purpose of this consensus is to reduce catheter-related complications, ensure the longevity of PICC and the safety of patient treatment.
ObjectivesTo systematically review the influence for catheter mechanical dysfunction of different peritoneal dialysis catheterization methods.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were searched to collect randomized controlled trials (RCTs) and cohort studies on comparisons of different peritoneal dialysis catheterization from inception to March 31st, 2018. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Network meta-analysis was then performed by using ADDIS 1.16.6 software.ResultsA total of 33 studies (9 RCTs and 24 cohort studies) involving 3 301 patients were included. Network meta-analysis showed that the incidence of catheter mechanical dysfunctionwas the least and had statistically significant difference compared with that in percutaneous catheterization (OR=3.60; 95%CI, 1.64 and 15.38) and open surgery catheterization (OR=5.86; 95%CI, 2.68 and 14.53). Percutaneous catheterization was superior to open surgery catheterization, but there was no significant difference.ConclusionsLaparoscopic catheterization may be the best technique for catheter insertion in peritoneal dialysis considering catheter dysfunction. Each technology has its own advantages. Choice of insertion method should be based on the characteristics of both the patient and the insertion techniques.
Objective To understand the urination of orthopedic patients after the catheter is removed, and to explore the influencing factors of urodynia. Methods Convenient sampling was used to select 160 patients who underwent surgical treatment in the Department of Orthopedics of West China Hospital of Sichuan University from May to July 2020. Questionnaires were used to investigate the patients’ urination, and a logistic regression model was used to analyze the factors affecting the patients’ urodynia. Results A total of 157 patients urinated by themselves after the catheter was removed, with 102 cases of dysuria. Logistic regression results showed that male [odds ratio (OR)=0.282, 95% confidence interval (CI) (0.092, 0.863), P=0.027], Huaxi Emotional-Distress Index score [OR=1.407, 95%CI (1.124, 1.760), P=0.003] and intraoperative fluid infusion [OR=1.001, 95%CI (1.000, 1.002), P=0.014] were the influencing factors of urodynia. Conclusion Most orthopedic patients can urinate on their own after the catheter is removed, but more than half of the patients experience urodynia during the first urination. Gender, mental status and intraoperative fluid infusion are the influencing factors of urodynia after urinary catheter removal after surgery. Clinical nursing staff should identify these influencing factors as soon as possible and carry out targeted interventions to improve the success rate of patients with urination after removing the catheter, reduce the incidence of urodynia, and promote the recovery of patients.
ObjectiveTo evaluate the effectiveness and safety of the additional catheter-directed thrombolysis (CDT) and conventional treatment (CT) for treatment primary deep vein thrombosis. MethodsDatabases such as CNKI, WanFang Data, Pubmed, EMBASE.com, Medline, CBM, CSJD, CJFD, and the Cochrane Library were electronically searched from the date of their establishment to 30 June, 2013, and the relevant literatures and conference proceedings were also manually searched to include randomized controlled trials (RCTs) on comparison of additional CDT versus CT for primary deep vein thrombosis. Two reviewers independently screened studies according to the inclusion and exclusion criteria, extracted data, and accessed the methodological quality of the included studies. Then the meta-analysis was performed by using RevMan 5.1 software. Publication bias was assessed by STATA software. A meta-regression model was used to describe between study variability. ResultsTwo RCTs including 3 literatures contain 224 patients reporting data on safety and efficacy of CDT versus CT were included. There were no publication bias (Begg'S test, Z=1.02. P > 0.05;Egger'S test, t=0.98, P > 0.05). The results of meta-analysis showed that:in 6 months after surgery iliofemoral vein patency rate of CDT group was higher than that of CT group (OR=3.62, 95% CI:1.51-8.64, P=0.004), in 6 months after surgery CDT group with a lower rate than CT group of the iliofemoral vein occlusion and (or)venous reflux rate (OR=0.24, 95% CI:0.11-0.53, P=0.000), and the incidence rate of PTS in 24 months after surgery in CTD group was less than that of CT group (OR=0.55, 95% CI:0.31-0.96, P=0.040). There were no statistically significant of the major complications after surgery between CDT group and CT group (OR=1.34, 95% CI:0.12-15.69, P=0.810). But the incidence rates of minor complications and total complications after surgery in CT group were lower than those of CDT group (OR=13.67, 95% CI:4.08-45.83, P < 0.00 01 and OR=11.67, 95% CI:4.40-30.99, P < 0.000 01). ConclusionsCDT is a effective and positive way to treat early deep venous thrombosis especially in terms of the patency of vascular and prevent the occlusion and PTS. Due to the limitation of the included studies, large sample size, multicenter, and high quality studies are needed to verify the above conclusion, such as the ATTRACT Study. The intracavitary therapy could be applied to clinic combining individual conditions of patients.
