Background: Central venous catheters and midline catheters are commonly used as medium‐ to long‐term intravenous infusion tools in clinical nursing. However, there is currently no reliable conclusion on whether there are differences in complications and indwelling time between these two types of catheters. Aim: To investigate whether there are differences in the incidence of complications and indwelling time between the use of midline catheters and central venous catheters as intravenous infusion tools. Methods: A systematic search was conducted across various databases including Web of Science, PubMed, Embase, Cochrane Library, CINAHL, Wanfang and China National Knowledge Infrastructure. The selection of studies and assessment of their quality was carried out independently by two reviewers. Meta‐analysis was conducted using the RevMan 5.3 software. Heterogeneity was evaluated, one of the pooled analyses was performed using the random‐effect model, while the others used the fixed‐effect model. Mean differences or odds ratios with corresponding 95% confidence intervals were calculated. Results: Ten studies (1,554 participants) met the inclusion criteria. Meta‐analysis showed that there was a statistically significant difference in the complication rates [OR = 0.36, 95% CI (0.18, 0.70), p = 0.003], incidence of catheter‐related thrombosis [OR = 0.28, 95% CI (0.11, 0.71), I2 = 0%,p = 0.007], catheter‐related infection[OR = 0.36, 95% CI (0.16, 0.78), I2 = 27%, p = 0.007] and catheter blockage [OR = 0.21, 95% CI (0.09, 0.51), I2 = 18%, p = 0.0005] between midline catheters group and central venous catheters group. There was a statistically significant difference in the catheter indwelling time between the two groups [MD = 0.9, 95% CI (0.33, 1.46), I2 = 0%, p = 0.002]. There was no significant difference in other complications such as phlebitis, catheter dislodgement and leakage between the two groups. Linking Evidence to Action: Midline catheter was superior to central venous catheter in terms of the overall complication rates and incidence of catheter‐related thrombosis, catheter blockage, catheter‐related infection and indwelling time. Summary statement: What is already known about this topic? Choosing appropriate intravenous infusion tools can reduce the occurrence of complications and improve the safety of treatment. As two common medium and long‐term infusion tools, MCs and CVCs are widely used in nursing practice.Some studies have explored the comparison of complications and indwelling time between MCs and CVCs, but the conclusions vary between studies. What this paper adds? This first systematic assessment of the complications and indwelling time between MCs and CVCs.There was a statistically significant difference in the overall complication rates, incidence of catheter‐related thrombosis, catheter‐related infection and catheter blockage between MCs and CVCs.There was a statistically significant difference in the indwelling time between MCs and CVCs. The implications of this paper: MCs offer several advantages over CVCs in terms of implantation method, minimizing catheter‐related complications, and prolonging catheter indwelling time.Findings can be applied as a reference to help nurses select an appropriate intravenous infusion catheter according to patients' needs.

Bloodstream infection (BSI) is characterized by high mortality, especially among these increasing super-elderly patients (≥ 85 years), and this study was conducted to understand the species distribution, typical clinical features and risk factors for poor prognosis of super-elderly patients with BSI. Methods: Based on previous work, this retrospective study was performed by reviewing an ongoing prospective medical database in a comprehensive tertiary center in China, and all super-elderly patients with BSI in the past 6 years were enrolled in this study. Results: Out of 5944 adult-patients with BSI, there were totally 431 super-elderly patients (≥ 85 years old) enrolled in this study and age ≥ 90 years accounted for 31.1% (134/431). Among these 431 super-elderly patients with BSI, 40 patients (9.3%) were diagnosed with BSI and the remained 401 super-elderly patients (90.7%) were defined as hospital-acquired BSI. The typical feature of these super-elderly patients with BSI was the high proportion of patients with various comorbidities, such as cardiovascular disease (83.8%), ischemic cerebrovascular disease (63.3%) and pulmonary infection (61.0%). The other typical feature was that most (60.1%) of these patients had been hospitalized for long time (≥ 28 days) prior to the onset of BSI, and most patients had received various invasive treatments, such as indwelling central venous catheter (53.1%) and indwelling urinary catheter (47.1%). Unfortunately, due to these adverse features above, both the 7-day short-term mortality (13.2%, 57/431) and the 30-day long-term mortality (24.8%, 107/431) were high. The multivariate analysis showed that both chronic liver failure (OR 7.9, 95% CI 2.3– 27.8, P=0.001) and indwelling urinary catheter (OR 2.3, 95% CI 1.1– 4.7, P=0.023) were independent risk factors for 7-day short-term mortality, but not for 30-day long-term mortality. In addition, the microbiology results showed that the most common species were associated with nosocomial infection or self-opportunistic infection, such as Staphylococcus hominis (18.3%), Staphylococcus epidermidis (11.8%), Escherichia coli (9.7%), Klebsiella pneumoniae (9.3%) and Candida albicans (8.6%, fungi). Conclusion: Super-elderly patients with BSI had typical features, regardless of the pathogenic species distribution and their drug resistance, or clinical features and their risk factors for poor prognosis. These typical features deserved attention and could be used for the prevention and treatment of BSI among super-elderly patients. [ABSTRACT FROM AUTHOR]

Background: China has not yet established a national surveillance network such as NHSN from America, so there is still no large-scale investigations on central line-associated bloodstream infection (CLABSI) incidence. Several retrospective studies in China reported that the incidence of CLABSI varied due to inconsistent diagnostic criteria. We performed a nationwide survey to investigate the utilization rate of central venous catheters (CVCs) and the incidence of CLABSI in ICUs of different areas of China.Methods: This is a prospective multi-center study. Patients admitted to ICUs with the use of CVCs between January 1, 2014 and December 31, 2018 were enrolled in this study. Hospitals were given the definition of catheter-related bloodstream infection as: a laboratory-confirmed bloodstream infection where CVC was in place on the date of event or the day before. The characteristics of patients, information of catheterization, implementation rates of precautions, and CLABSIs were collected. The statistical analysis was performed by SPSS 25.0 software and website of Open Source Epidemiologic Statistics for Public Health.Results: A total of 38,212 patients and 466,585 catheter days were involved in surveillance. The average CLABSI incidence in a thousand catheter days was 1.50, the lowest incidence unit was in pediatric ICU (0/1000 catheter days), and the lowest incidence area was in Northeast China (0.77/1000 catheter days), while the highest incidence unit was in cardiac ICU (2.48/1000 catheter days) and the highest incidence area was in Eastern China (1.62/1000 catheter days). The average utilization rate of CVC was 42.85%, the lowest utilization rate was in pediatric ICU (5.85%) and in Central China (38.05%), while the highest utilization rate was in surgical ICU (64.92%) and in Western China (51.57%). Among the 702 CLABSI cases reported, a total of 735 strains of pathogens were cultured. Staphylococcus spp. was the most common organism isolated (27.07%), followed by Enterobacteriaceae (22.31%). The implementation rates of all precautions showed an upward trend during the study period (P ≤ 0.001).Conclusion: The average incidence of CLABSI in ICUs in China is 1.5/1000 catheter days, similar to the rates reported in developed countries but lower than previous reports in China. CLABSI incidence showed regional differences in China. It is necessary to implement targeted surveillance of CLABSI cases by using standardized CLABSI surveillance definitions and methodologies.

Introduction: Catheter management strategies for suspected catheter-related bloodstream infection (CRBSI) remain a major challenge in intensive care units (ICUs). The objective of this study was to determine the incidence, risk factors, and mortality attributable to CRBSIs in those patients. Methods: A population-based surveillance on suspected CRBSI was conducted from 2009 to 2018 in a tertiary care hospital in China. We used the results of catheter tip culture to identify patients with suspected CRBSIs. Demographics, systemic inflammatory response syndrome (SIRS) criteria, interventions, and microorganism culture results were analysed and compared between patients with and without confirmed CRBSIs. Univariate and multivariate analyses identified the risk factors for CRBSIs, and attributable mortality was evaluated with a time-varying Cox proportional hazard model. Results: In total, 686 patients with 795 episodes of suspected CRBSIs were included; 19.2% (153/795) episodes were confirmed as CRBSIs, and 17.4% (119/686) patients died within 30 days. The multifactor model shows that CRBSIs were associated with fever, hypotension, acute respiratory distress syndrome, hyperglycaemia and the use of continuous renal replacement therapy. The AUC was 77.0% (95% CI 73.3%–80.7%). The population attributable mortality fraction of CRBSI in patients was 18.2%, and mortality rate did not differ significantly between patients with and without CRBSIs (95% CI 0.464–1.279, P = 0.312). Conclusions: This initial model based on the SIRS criteria is relatively better at identifying patients with CRBSI but only in domains of the sensitivity. There were no significant differences in attributable mortality due to CRBSI and other causes in patients with suspected CRBSI, which prompt catheter removal and re-insertion of new catheter may not benefit patients with suspected CRBSIs.

Background: Maintaining venous access is of great clinical importance. Running a slow continuous infusion to keep the vein open (KVO) is often used in peripheral intravenous catheters (PIVCs). Previous studies have compared the effects of intermittent flushing and continuous infusion via peripherally inserted central catheters (PICCs). In this study, we applied KVO to central venous catheters (CVCs) and compared the occlusion rate of this technique with that of the intermittent flushing technique., Method: This is a randomized controlled trial of 14 hospitals in China. A total of 250 patients will be recruited in this study, and they will be randomized at a 1:1 ratio. After study inclusion, patients who will undergo CVC insertion will receive intermittent flushing with prefilled saline syringes (control group) or KVO infusion with elastic pumps (test group). All the catheters will be checked for patency by scoping Catheter Injection and Aspiration (CINAS) Classification on Days 3 and 7. The primary outcome is the rate of catheter occlusion in 7 days. Patients will be followed up until 9 days after CVC insertion, catheter occlusion, or catheter removal. The secondary outcomes are the rate of catheter occlusion in 3 days, nurse satisfaction, cost-effectiveness, adverse event rate, catheter-related bloodstream infection rate, catheter-related thrombosis rate, extravasation rate, phlebitis rate, and catheter migration., Discussion: We expect that the trial will generate findings that can provide an evidence-based basis for the improvement and optimization of clinical catheter flushing techniques., Trial Registration: Chinese Clinical Trial Registry, ChiCTR2200064007.

Central venous catheters are widely used in clinical practice, and the incidence of central venous catheter occlusion is between 25 % and 38 %. The turbulence caused by the pulsatile flushing technique is harmful to the vascular endothelium and may lead to phlebitis. The low-speed continuous infusion catheter technique is a new type of continuous infusion that ensures that the catheter is always in a keep-vein-open state by continuous low-speed flushing; hence, avoiding the problem of catheter occlusion. To investigate the effectiveness of the low-speed continuous infusion catheter technique and the routine care of double-lumen central venous catheters. This was a prospective, randomized, controlled, open-label trial. Patients were recruited from 14 medical institutions in China between February and June 2023. In total, 251 patients were recruited, with 125 in the intervention group and 126 in the control group. Patients who used double-lumen central venous catheters for infusion treatment were selected, and those who met the sampling criteria were randomly divided into intervention and control groups using the random envelope method. The intervention group used the low-speed continuous infusion catheter technique to maintain catheter patency, whereas the control group used routine care with a trial period of 7 days. The primary outcome was the occlusion rate. The secondary outcomes included nursing satisfaction and complication rates of the two groups. After 7 days, the rate of catheter occlusion was 28.0 % (35/125, 95 % confidence interval (CI):0.203, 0.367) in the intervention group and 53.97 % (68/126, 95 % CI: 0.449–0.629) in the control group, with a statistically significant difference (χ2 = 17.488, p < 0.001); at 3 days of intervention, the rate of catheter blockage was 8.0 % (10/125, 95 % CI: 0.039–0.142) in the intervention group and 23.8 % (30/126, 0.167–0.322) in the control group, with a statistically significant difference (χ2 = 11.707, p < 0.001). Nurse satisfaction was significantly higher in the intervention group (115/125, 92.0 %, 95 % CI: 0.858–0.961) than in the control group (104/126, 82.54 %, 95 % CI: 0.748–0.887) (χ2 = 5.049, p = 0.025). There were no statistically significant complication rates in either group (p = 0.622). The low-speed continuous infusion catheter technique helps maintain catheter patency, improves nurse satisfaction, and provides a high level of safety.

Abstract Background Peripherally-inserted central catheter-related venous thrombosis has serious complications including the loss of vascular access, recurrent venous thrombosis, and post-thrombotic syndrome. Current guidelines recommend non-pharmacological strategies to prevent peripherally-inserted central catheter-related venous thrombosis. There is little evidence for the effectiveness of handgrip exercise on the prevention of peripherally-inserted central catheter-related venous thrombosis. Objectives To examine the effectiveness of handgrip exercise using an elastic ball to prevent peripherally-inserted central catheter-related venous thrombosis in patients with solid cancers. Design A randomized controlled trial. Settings One teaching hospital in Nanjing, China. Participants In total, 120 subjects with solid cancers were eligible; each had a new peripherally-inserted central catheter. They were recruited and randomly assigned into two exercise groups and one control group. Methods Subjects from exercise groups 1 and 2 performed a 3-week, 25-repetition handgrip exercise, 3 and 6 times daily, respectively. The control group subjects performed a gentle limb exercise with no frequency and intensity requirements. Ultrasound was used to detect venous thrombosis development and examine axillary vein blood flow over the three points. Results There were 32 cases of peripherally-inserted central catheter-related venous thrombosis detected. Two venous thrombosis cases in the control group were symptomatic, but all venous thrombosis cases in the exercise groups were asymptomatic. All venous thromboses were partial. There were significant differences in the incidence of venous thrombosis among the three groups (χ2 = 12.813, p = 0.002; χ2 = 9.340, p = 0.009; χ2 = 11.480, p = 0.003; and χ2 = 10.534, p = 0.005, respectively) at days 2, 3 and 21. The incidence of venous thrombosis in the two exercise groups was lower than that in the control group over the 3 time points (all, p < 0.05). The between-group effects and interaction effect in vein maximum velocity and time-mean flow velocity showed significant differences (F = 4.180, p = 0.025; F = 4.010, p = 0.045; and F = 2.928, p = 0.025) at days 2, 3, and 21, respectively. The axillary vein blood flow parameters in the control group were lower than those in the two exercise groups at day 21 (all, p < 0.05). However, no significant differences occurred in the incidence of venous thrombosis and axillary vein blood flow parameters between the two exercise groups. Conclusion Handgrip exercise using an elastic ball daily for three weeks could decrease the incidence of peripherally-inserted central catheter-related venous thrombosis. The method is simple, with no negative consequence reported. Further studies are required to confirm this conclusion and to explore the optimal frequency of handgrip exercise. [ABSTRACT FROM AUTHOR]

Aims and objectives To describe the incidence of prolonged fever in patients admitted to the neurosurgery department, and the corresponding risk indicators. Background Prolonged fever was defined as a temperature higher than 38·3°C lasting more than five days. Prolonged fever is a common phenomenon and could lead to worsened outcomes in specific patient groups, especially for those with brain injury. However, the studies on prolonged fever in neurosurgical patients are limited and insufficient. Design A retrospective observational study. Methods Retrospective data were collected from 1 January 2014 to 31 December 2014, at the neurosurgical department of a large teaching hospital. We performed univariate and multivariate analyses to identify independent indicators for prolonged fever vs. short-term fever. Results Among 2845 patients, prolonged fever occurred in 466 (16%). The older patients were associated with longer duration of mechanical ventilation and hospital stay. It predominantly occurred in patients with subarachnoid haemorrhage ( SAH) and traumatic brain injury. Patients receiving antibiotic treatment tended to manifest prolonged fever more frequently. Multivariate analysis revealed that the use of antibiotics, central venous catheter and prolonged mechanical ventilation were independent risk predictors for prolonged fever. Patients diagnosed with brain tumour seemed to be not associated with prolonged fever. Conclusions Prolonged fever is the common complication in neurosurgical patients. The risks of prolonged fever in patients are attributed to antibiotic therapy, use of central venous catheter and prolonged mechanical ventilation. Indicators of prolonged fever are helpful for better identification of high-risk patients and fever control. Relevance to clinical practice A better reveal on the epidemiology and predictable factors of prolonged fever in neurosurgical patients will provide a better understanding on those patients who are most at risk, and therefore contribute to fever control and better outcome.

Background: Ultrasound-guided axillary vein catheterization is now widely used in hospital, but it remains uncertain whether the distal axillary vein approach is more beneficial for seniors than the proximal axillary vein approach. This study aims to compare the puncture success rate and anatomical characteristics between these two approaches., Methods: Senior patients requiring central venous catheterization were enrolled and randomized to the proximal axillary vein group ( n  = 49) or the distal axillary vein group ( n  = 50). Proximal axillary vein and distal axillary vein location time, venous depth, maximum diameter, and collapse index (defined as the percentage change in vein width caused by respiration) were recorded for all patients. The rate of puncture success and operation time were compared between groups., Results: Mean venous depth was 1.93 ± 0.45 cm for proximal axillary vein and 1.79 ± 0.46 cm for distal axillary vein ( p  < 0.001). Maximum diameter was 0.80 ± 0.33 cm for proximal axillary vein and 0.61 ± 0.33 cm for distal axillary vein ( p  < 0.001). Collapse indices were 20% ± 27% and 56% ± 34%, respectively ( p  < 0.001). Also, location time was significantly shorter for proximal axillary vein than for distal axillary vein ( p  < 0.001). One attempt and overall success rates were significantly higher in the proximal axillary vein group, compared with the distal axillary vein group (71.4% vs 42.0%, p  = 0.003; 79.6% vs 54.0%, p  = 0.007)., Conclusion: For catheterization under ultrasound guidance in elderly patients, the proximal axillary vein approach is superior to the distal axillary vein approach.

Objective: This study was performed to evaluate the effect of care bundles on the prevention of central venous catheter-related bloodstream infection (CRBSI) and improvement of patients' experience., Methods: In total, 212 patients with central venous catheter insertions were enrolled in this study. All patients were matched by sex, age, Acute Physiology and Chronic Health Evaluation II score, body mass index, department, and catheter insertion site and were randomly divided into case and control groups (n = 106 each). The control group was given conventional care, and the case group was given care bundles including nurse education, hand hygiene, maximal sterile barrier precautions, bedside observation, and evaluation. The anxiety scores, hospitalization days, CRBSI rate, and degree of satisfaction with hospitalization were compared between the two groups., Results: The patients' mean self-rating anxiety scale score and self-rating depression scale score after nursing intervention were significantly lower in the case group than in the control group. The mean number of hospitalization days and CRBSI rate were significantly lower and the satisfaction rate was significantly higher in the case group., Conclusion: Care bundles are essential for preventing CRBSI. They can improve patients' psychological state and hospitalization satisfaction and reduce the hospitalization days.

Background: Acute kidney injury (AKI) is common in critically ill neonates, and peritoneal dialysis (PD) can be a lifesaving option. In China, however, much of the equipment for PD in neonates is not available. We describe results with a novel system for PD, which has been developed locally to improve access to therapy and care for critically ill neonates requiring PD in China., Methods: The system comprises a 14-gauge single-lumen central venous catheter serving as a PD catheter, inserted by Seldinger technique, with an adapted twin bag PD system. Ten neonates with AKI were treated using the novel PD system., Results: The 10 patients ranged in age from 1 day to 22 days, with bodyweights between 700 g and 3,300 g. Average time to renal function recovery was between 14 and 96 hours. Complications related to the novel PD system included leak ( n = 1), catheter displacement ( n = 1), and catheter obstruction ( n = 1). There were no complications related to insertion, no cases of peritonitis or exit-site infection, and no subsequent hernias. A comparison of costs indicated that the novel PD system is less expensive than conventional systems involving open insertion of Tenckhoff catheters., Conclusions: Peritoneal dialysis using the novel PD system is simple, safe, and effective for suitable neonates with AKI in China., (Copyright © 2018 International Society for Peritoneal Dialysis.)
