Cardiovascular Intervention in Neonates Using an Umbilical Vein Approach.

Cardiovascular catheterization has been applied in infant treatment for several decades. To date, considerable research attention has been paid to cardiovascular catheterization in small neonates. However, peripheral vascular routes of catheterization are possible obstacles for interventionists. Umbilical vein catheterization has been reported as a route for neonates, although few attempts have been made to investigate this approach. This study aimed to retrospectively review cardiovascular intervention using the umbilical vein approach as applied to infants admitted to a tertiary center from 2017 to 2020. Details including the perinatal variables, indication diagnoses, and procedure devices were collected. The enrollment included a total of 16 cases representing 17 intervention events, with infants born at a gestation age of 22–39 weeks and body weight ranging from 478 to 3685 g at the time of the procedure. The postnatal age ranged from 1 to 27 days. The catheter sizes ranged from 4 to 11 Fr. Indications included being admitted for patent ductus arteriosus occlusion (n = 15), balloon pulmonary valvuloplasty (n = 3), balloon atrial septostomy (BAS) (n = 3), pulmonary valve (PV) perforation (n = 1), and two interventions for catheter placement for continuous venovenous hemofiltration. The success rate for cardiovascular catheterization was 88.2% (15/17). There were two patients for which cannulation failed due to ductus venosus closure: one intraabdominal hemorrhage complication during continuous venovenous hemofiltration (CVVH), and one cardiac catheterization failure of PV perforation due to failure to insert the guiding catheter into the right ventricular outflow tract. Based on these findings, we conclude that cardiac catheterization and the placement of a large-sized catheter through an umbilical vein in a small infant represents a safe and time-saving method when catheterization is required.

Securement bundles to prevent peripheral intravenous catheter failure – the SECURE-PIVC trial: A pilot randomised controlled trial

Introduction: Around half of peripheral intravenous catheters (PIVCs) fail before treatment completion. Effective PIVC securement reduces failure but optimal ways to achieve this is unclear. We tested the feasibility of two securement bundles against standard care to prevent PIVC failure in a pilot randomised controlled trial (RCT).

Catheter failure in the administration of hyperosmotic drugs through a peripheral vein and vascular selection: A retrospective cohort study.

This study aimed to determine whether the placement of a peripheral intravenous catheter (PIVC) in the cephalic vein of the forearm could prevent PIVC failure in patients receiving hyperosmotic drugs through the peripheral vein. This retrospective cohort study included patients aged ≥ 20 years who had received infusion therapy via a PIVC in our institution between July and November 2017. Patients were divided into groups according to PIVC insertion into the cephalic, basilic, and medial veins. PIVCs used to administer drugs with osmotic pressure ratios > 2.0 were included. The primary outcome was survival time to catheter failure. Catheter failure was defined as accidental and unplanned catheter removal. We set the cephalic vein and other veins, including the medial and basilic veins, in the forearm as cohort groups. We used the Kaplan-Meier survival curves to compare the time until catheter failure in the cohort groups. The Cox proportional hazard models were fitted, and the hazard ratios were calculated. A total of 46 catheters with hyperosmotic agents were included in the analysis. Catheter failure was observed in 25 (54.3%) cases. Time to catheter failure in patients receiving high-dose drugs via the cephalic vein was significantly longer than that in the other two groups (p < 0.01). Thus, the cephalic vein, which has a high blood flow, is the ideal site of PIVC insertion in patients receiving high drug concentrations to prevent catheter failure.

Introduction of advanced laparoscopy for peritoneal dialysis catheter placement and the outcome in a University Hospital

BackgroundPeritoneal dialysis (PD) catheters can be obstructed by omental wrapping or migration, leading to catheter malfunction. Multiple catheter placement techniques have been described. Advanced laparoscopy with fixation of the catheter and omentum has been reported to improve functional outcome compared to basic laparoscopy without fixation. This feasibility study describes surgical technique, complications, and comparison of the functional outcome of advanced versus basic laparoscopic catheter placement.MethodsBetween July 2016 and April 2019, the advanced laparoscopy technique was applied in all eligible patients. Two experienced surgeons placed the catheters in a standardized procedure. Peri-operative complications and functional outcome of the catheter were scored. Results were compared to a historical cohort retrieved from our RCT performed earlier using basic laparoscopy.FindingsThe basic laparoscopic group (BLG) consisted of 46 patients and the advanced laparoscopic group (ALG) of 32. Complication rate in both groups was similar and low with 7% in the BLG and 6% in the ALG (p = 1.0). There was a trend toward better functional catheter outcome in the ALG (88%) compared to the BLG (70%) (p = 0.1). Part of the catheter failures in the ALG could be related to the learning curve. After revision surgery, 94% of patients in the ALG had a functional catheter. These findings lead to the set-up of a multi-center randomized-controlled trial, currently running, comparing basic to advanced laparoscopic techniques.

Comparison of 2 Midline Catheter Devices With Differing Antithrombogenic Mechanisms for Catheter-Related Thrombosis

Data regarding upper extremity midline catheter (MC)-related thrombosis (CRT) are sparse, with some evidence indicating that MCs have a high rate of CRT. To compare 2 MCs with differing antithrombogenic mechanisms for this outcome. In this parallel, 2-arm randomized clinical trial, 496 adult patients hospitalized at a tertiary care suburban academic medical center who received an MC were assessed for eligibility between January 1, 2019, and October 31, 2020, and 212 were randomized. Inpatients were randomized to receive a 4F antithrombotic MC (MC-AT) or a 4.5F antithrombotic and antimicrobial MC (MC-AT-AM). The primary outcome was symptomatic midline CRT inclusive of deep vein thrombosis or superficial venous thrombophlebitis within 30 days after insertion. Secondary outcomes included catheter-associated bloodstream infection and catheter failure. A total of 191 patients (mean [SD] age, 60.2 [16.7] years; 114 [59.7%] female) were included in the final analysis: 94 patients in the MC-AT group and 97 in the MC-AT-AM group. Symptomatic midline CRT occurred in 7 patients (7.5%) in the MC-AT group and 11 (11.3%) in the MC-AT-AM group (P = .46). Deep vein thrombosis occurred in 5 patients (5.3%) in the MC-AT group and 5 patients (5.2%) in the MC-AT-AM group (P > .99). Pulmonary embolism occurred in 1 patient in the MC-AT group. No catheter-associated bloodstream infection occurred in either group. Premature catheter failure occurred in 22 patients (23.4%) in the MC-AT group and 20 (20.6%) in the MC-AT-AM group (P = .64). In Cox proportional hazards regression analysis, no statistically significant difference was found between groups for the risk of catheter failure (hazard ratio, 1.27; 95% CI, 0.67-2.43; P = .46). No difference was found in thrombosis in MCs with 2 distinct antithrombogenic mechanisms; however, the risk of CRT in both groups was high. Practitioners should strongly consider the safety risks associated with MCs when determining the appropriate vascular access device. ClinicalTrials.gov Identifier: NCT03725293.

The S2C Study – Securing Cannulas in Combat: a simulation-based mixed-method study

Introduction Haemorrhage is the leading cause of preventable death in combat settings. Pre-hospital practice guidelines advocate for the rapid delivery of blood products and intravenous access to deliver adjunct treatments. However, peripheral intravenous catheter (PIVC) insertion is challenging in the austere setting, and catheter failure is common. This study aims to investigate dressing and securement methods to prevent catheter dislodgement and explore participants’ experiences with these methods within an Australian Defence Force Tactical Combat Casualty Care (TCCC) training course. Methods and analysis A two-phase mixed-method design will be used to compare the Ruggedised Field (Ranger) method with the S-Wrap technique to reduce PIVC dislodgement rates during TCCC simulations. The study will be undertaken at the Australian Army School of Health in Victoria, Australia. In Phase 1, we will examine the pull-out force of each dressing securement method in vitro. Phase 2 will involve (i) an observational audit (n=30 participants) of TCCC training to assess the quality and safety of PIVC securement practices and (ii) focus groups with participating healthcare professionals (HCPs) (n<15 participants) to understand their lived experiences of PIVC insertion and securement practices. Associations between pull-out forces will be assessed using analysis of variance, and descriptive statistics will be used to summarise audit data. Focus group data will be analysed using content analysis.

Peripheral intravenous catheter failure: A secondary analysis of risks from 11,830 catheters

BackgroundPeripheral intravenous catheters are an essential medical device which are prone to complications and failure. ObjectivesIdentify patient, provider and device risk factors associated with all-cause peripheral intravenous catheter failure as well as individual complications: phlebitis, infiltration/occlusion, and dislodgement to improve patient outcomes. DesignSecondary analysis of twelve prospective studies performed between 2008 and 2020. SettingsAustralian metropolitan and regional hospitals including one paediatric hospital. ParticipantsParticipants were from medical, surgical, haematology, and oncology units. MethodsMultilevel mixed-effects parametric survival regression was used to identify factors associated with all-cause peripheral intravenous catheter failure, phlebitis, occlusion/infiltration, and dislodgement. We studied patient (e.g., age, gender), device (e.g., gauge), and provider (e.g., inserting clinician) variables. Stepwise regression involved clinically and p<0.20 significant variables entered into the multivariable model. Results were expressed as hazard ratios (HRs) and 95% confidence intervals (CI); p<0.01 was considered statistically significant. ResultsOf 11,830 peripheral intravenous catheters (8,200 participants) failure occurred in 36% (n = 4,263). Occlusion/infiltration incidence was 23% (n = 2,767), phlebitis 12% (n = 1,421), and dislodgement 7% (n = 779) of catheters. Patient factors significantly associated with failure and complications were: female gender (phlebitis; (HR 1.98, 95% CI 1.72–2.27), (infiltration/occlusion; HR 1.45, 95% CI 1.33–1.58), (failure; HR 1.36, 95% CI 1.26–1.46); and each year increase in age (phlebitis; 0.99 HR, 95% CI 0.98–0.99), (failure; 0.99 HR, 95% CI 0.99–0.99). The strongest provider risk factor was intravenous antibiotics (infiltration/occlusion; HR 1.40, 95% CI 1.27–1.53), (phlebitis; HR 1.36, 95% CI 1.18–1.56), (failure; HR 1.26, 95% CI 1.17–1.36). Catheters inserted by vascular access teams were less likely to dislodge (HR 0.53, 95% CI 0.42–0.67). Device risk factors most associated with all-cause failure were wrist/hand (HR 1.34, 95% CI 1.23–1.46), antecubital fossa peripheral intravenous catheters (HR 1.29, 95% CI 1.16–1.44) and 22/24 gauge (HR 1.27, 95% CI 1.12–1.45) catheters. ConclusionFactors identified, including the protective aspect of vascular access team insertion, and high catheter failure associated with intravenous antibiotic administration, will allow targeted updates of peripheral intravenous catheter guidelines and models of care.

Performance of peripheral catheters inserted with ultrasound guidance versus landmark technique after a simulation-based mastery learning intervention.

Ultrasound-guided peripheral intravenous catheter (USGPIV) insertion is an effective method to gain vascular access in patients with difficult intravenous access (DIVA). While USGPIV success rates are reported to be high, some studies have reported a concerning incidence of USGPIV premature failures. The purpose of this study was to compare differences in USGPIV and landmark peripheral intravenous catheter (PIV) utilization and failure following a hospital-wide USGPIV training program for nurses. The authors performed a retrospective, electronic medical record review of all USGPIVs and PIVs inserted at a tertiary, urban, academic medical center from September 1, 2018, through September 30, 2019. The primary outcome was differences between USGPIV and PIV time to failure. A total of 43,470 short peripheral intravenous catheters (PIVCs) were inserted in 23,713 patients. Of these, 7972 (16.8%) were USGPIV. At 30 days of follow-up, for PIVCs with an indication for removal documented, USGPIVs had higher Kaplan-Meier survival probabilities than PIVs (p < 0.001). The use of simulation-based mastery associated with USGPIVs, demonstrated lower failure rates than standard PIVs after 2 days and USGPIVs exhibited improved survival rates in patients with DIVA. These findings suggest that rigorous simulation-based insertion training demonstrates improved USGPIV survival when compared to traditional PIVCs. SBML is an extremely useful tool to ensure appropriately trained clinicians acquire the necessary knowledge and skillset to improve USGPIV outcomes.

Safety of Continuous Erector Spinae Catheters in Chest Trauma: A Retrospective Cohort Study.

The erector spinae block is an efficacious analgesic option for the management of rib fracture--related pain. Despite there being minimal published data specifically addressing the safety profile of this block, many societies have made statements regarding its safety and its use as an alternative to traditional regional anesthesia techniques in patients at risk of complications. The primary aim of this study was to characterize the safety profile of erector spinae plane block catheters by determining the incidence of early complications. The secondary aim of this study was to characterize the incidence of late adverse events, as well as the erector spinae plane block catheter failure rate. We analyzed electronic medical record data of patients who had an erector spinae plane block catheter inserted for the management of rib fractures between November 2017 and September 2020. To assess early adverse events, data collection included hypotension, hypoxemia, local anesthetic systemic toxicity, and pneumothorax thought to be associated with erector spinae plane block catheter insertion. Late complications included catheter site infection and catheter site hematoma. A total of 224 patients received 244 continuous erector spinae catheters during the study period. After insertion of the erector spinae, there were no immediate complications such as hypotension, hypoxia, local anesthetic toxicity, or pneumothorax. Of all blocks inserted, 7.7% were removed due to catheter failure (8.4 per 100 catheters; 95% confidence interval [CI], 5.1-13.9 per 100 catheters). This resulted in a failure rate of 1.9 per 1000 catheter days (95% CI, 1.1-6.7 catheter days). Late complications included 2 erythematous catheter sites and 2 small hematomas not requiring intervention. The incidence of a minor late complication was 16.7 per 1000 catheters (95% CI, 6.1-45.5 per 1000 catheters). This study supports the statements made by regional anesthesia societies regarding the safety of the erector spinae plane block. Based on the results presented in this population of trauma patients, the erector spinae plane block catheter is a low-risk analgesic technique that may be performed in the presence of abnormal coagulation status or systemic infection.

Peripheral intravenous catheter failure—is it us or is it them?

Intravenous therapy for patients with a range of haematological disorders is an essential component of disease treatment. Although central venous access devices are preferred for irritant or vesicant intravenous therapies, the peripheral intravenous catheter (PIVC) has an important role, offering a simple, cost-effective way to deliver short-term, peripherally compatible treatments. Unfortunately, this important device is susceptible to failure, with more than half of all PIVCs in hospitalised patients developing complications such as occlusion, infiltration, phlebitis, dislodgement, and infections that result in device removal.

Multimodal intervention for preventing peripheral intravenous catheter failure in adults (PREBACP): a multicentre, cluster-randomised, controlled trial

2 billion peripheral intravenous catheters (PIVC) are inserted into inpatients worldwide each year. Almost one in two PIVCs fail before completion of intravenous therapy. We aimed to determine the efficacy and costs of a multimodal intervention to reduce PIVC failure among hospitalised patients. PREBACP was a cluster-randomised, controlled trial done at seven public hospitals in Spain. Clusters (hospital wards) had at least 70% permanent staff and data were collected from patients aged 18 years and older with one or more PIVCs at the start of intravenous therapy. Clusters were randomly assigned (1:1) to the multimodal intervention or control group using a centralised, web-based randomisation software, and stratified by type of setting. We concealed randomisation to allocation, without masking patients or professionals to the intervention. An intervention using a multimodal model and dissemination of protocols, education for health-care professionals and patients, and feedback on performance was implemented for 12 months in the intervention group. The control group received usual care. The primary outcome was all-cause PIVC failure at 12 months (phlebitis, extravasation, obstruction, or infections). Subsequently, through an amendment to the protocol approved on July 25, 2021, we included dislodgement as part of PIVC failure. Analysis was by modified intention to treat, which included all randomly assigned hospital wards for whom data on the primary endpoint were available. This trial is registered with the ISRCTN Registry, ISRCTN10438530. Between Jan 1, 2019, and March 1, 2020, we randomly assigned 22 eligible clusters to receive the multimodal intervention (n=11 clusters; 2196 patients, 2235 PIVCs, and 131 nurses) or usual practice in the control group (n=11 clusters; 2282 patients, 2330 PIVCs, and 138 nurses). At 12 months, the proportion of PIVC failures was lower in the intervention group than in the control group (37·10% [SD 1·32], HR 0·81 [95% CI 0·72 to 0·92] vs 46·49% [2·59], HR 1·23 [1·04 to 1·39]; mean difference -9·39% [95% CI -11·22 to -7·57]; p<0·0001). Per-protocol-prespecified analysis of the primary outcome excluding dislodgement also showed the intervention significantly reduced PIVC failure compared with the control group at 12 months (33·47% [SD 2·98], HR 0·85 [95% CI 0·75 to 0·96] vs 41·06% [4·62], HR 1·18 [1·04 to 1·33]; mean difference -7·59% [95% CI -11·05 to -4·13]; p<0·0001). A multimodal intervention reduced PIVC failure, thereby reducing potentially serious complications for hospitalised patients. The findings of PREBACP enabled a deeper understanding of decision making, knowledge mobilisation, and sense making in routine clinical practice. The College of Nurses of the Balearic Islands.

Central Venous Disease Increases the Risk of Microbial Colonization in Hemodialysis Catheters.

Objectives: Tunneled-cuffed catheters (TCCs) are widely used in maintenance hemodialysis patients. However, microbial colonization in catheters increases the likelihood of developing various complications, such as catheter-related infection (CRI), catheter failure, hospitalization, and death. Identification of the risk factors related to microorganism colonization may help us reduce the incidence of these adverse events. Therefore, a retrospective analysis of patients who underwent TCC removal was conducted.Methods: From a pool of 389 adult patients, 145 were selected for inclusion in the study. None of the patients met the diagnostic criteria for CRI within 30 days before recruitment. The right internal jugular vein was the unique route evaluated. The catheter removal procedure was guided by digital subtraction angiography. Catheter tips were collected for culture. Biochemical and clinical parameters were collected at the time of catheter removal.Results: The average age of this cohort was 55.46 ± 17.25 years. A total of 45/145 (31.03%) patients were verified to have a positive catheter culture. The proportions of gram-positive bacteria, gram-negative bacteria, and fungi were 57.8, 28.9, and 13.3%, respectively. History of CRI [odds ratio (OR) = 2.44, 95% confidence interval (CI) 1.09 to 5.49], fibrin sheath (OR = 2.93, 95% CI 1.39–6.19), white blood cell (WBC) count ≥5.9 × 109/l (OR = 2.31, 95% CI 1.12–4.77), moderate (OR = 4.87, 95% CI 1.61–14.78) or severe central venous stenosis (CVS) (OR = 4.74, 95% CI 1.16–19.38), and central venous thrombosis (CVT) (OR = 3.41, 95% CI 1.51–7.69) were associated with a significantly increased incidence of microbial colonization in a univariate analysis. Central venous disease (CVD) elevated the risk of microbial colonization, with an OR of 3.37 (1.47–7.71, P = 0.004). A multivariate analysis showed that both CVS and CVT were strongly associated with catheter microbial colonization, with ORs of 3.06 (1.20–7.78, P = 0.019) and 4.13 (1.21–14.05, P = 0.023), respectively. As the extent of stenosis increased, the relative risk of catheter microbial colonization also increased. In patients with moderate and severe stenosis, a sustained and significant increase in OR from 5.13 to 5.77 was observed.Conclusions: An elevated WBC count and CVD can put hemodialysis patients with TCCs at a higher risk of microbial colonization, even if these patients do not have the relevant symptoms of infection. Avoiding indwelling catheters is still the primary method for preventing CRI.

Peripherally Inserted Central Catheters in Children: A Prospective Single-Center Analysis of Associated Complications

Highlights Abstract Objective: To assess performance of peripherally inserted central catheters (PICCs) in pediatric patients Design: Prospective observational study Setting: Academic pediatric tertiary referral center Study Population: Children aged less than 18 years with PICCs inserted in Interventional Radiology from January 2019 to June 2019 Outcome Measures: Number of catheters remaining in situ until completion of intended therapy; and for those removed prematurely, the type and rate of complications Results: A total of 88 PICCs (40 uncuffed, 48 cuffed) were inserted in 77 children. Overall, 72% (n = 63) of all catheters remained in situ until intended therapy was completed. Complications resulting in premature removal occurred in 24% of catheters (rate of 3.89/1000 catheter-days). Complications included catheter malfunction (2.04 per 1000 catheter-days), infection (1.67 per 1000 catheter-days), and thrombosis (0.18 per 1000 catheter-days). Complications were further recorded by catheter type. In patients with uncuffed catheters, the overall complication rate was observed to be 6.74 per 1000 catheter-days. In patients with cuffed catheters, the overall complication rate was observed to be 1.10 per 1000 catheter-days. Conclusions: Findings suggest that cuffed PICCs may provide additional benefits toward optimizing catheter performance and securement in neonatal and pediatric patients. This can contribute to improved likelihood of complication-free PICC therapy and successful therapy completion. Pediatric patients present unique challenges and considerations for clinicians planning PICC therapy. Additional studies are needed to identify effective strategies to mitigate catheter failure in neonatal and pediatric populations.

Early recognition of peripheral intravenous catheter failure using serial ultrasonographic assessments.

ObjectivePeripheral intravenous catheter (PIVC) failure occurs frequently, but the underlying mechanisms of failure are poorly understood. We aim to identify ultrasonographic factors that predict impending PIVC failure prior to clinical exam.MethodsWe conducted a single site prospective observational investigation at an academic tertiary care center. Adult emergency department (ED) patients who underwent traditional PIVC placement in the ED and required admission with an anticipated hospital length of stay greater than 48 hours were included. Ongoing daily PIVC assessments included clinical and ultrasonographic evaluations. The primary objective was to identify ultrasonographic PIVC site findings associated with an increased risk of PIVC failure. The secondary outcome was to determine if ultrasonographic indicators of PIVC failure occurred earlier than clinical recognition of PIVC failure.ResultsIn July and August of 2020, 62 PIVCs were enrolled. PIVC failure occurred in 24 (38.71%) participants. Multivariate logistic regression demonstrated that the presence of ultrasonographic subcutaneous edema [AOR 7.37 (1.91, 27.6) p = 0.0030] was associated with an increased likelihood of premature PIVC failure. Overall, 6 (9.67%) patients had subcutaneous edema present on clinical exam, while 35 (56.45%) had subcutaneous edema identified on ultrasound. Among patients with PIVC failure, average time to edema detectable on ultrasound was 46 hours and average time to clinical recognition of failure was 67 hours (P = < 0.0001).ConclusionsPresence of subcutaneous edema on ultrasound is a strong predictor of PIVC failure. Subclinical subcutaneous edema occurs early and often in the course of the PIVC lifecycle with a predictive impact on PIVC failure that is inadequately captured on clinical examination of the PIVC site. The early timing of this ultrasonographic finding provides the clinician with key information to better anticipate the patient’s vascular access needs. Further research investigating interventions to enhance PIVC survival once sonographic subcutaneous edema is present is needed.

Effectiveness of ultrasonography for peripheral catheter insertion and catheter failure prevention in visible and palpable veins.

The increase in the success rate of peripheral intravenous catheterization against a difficult intravenous access (DIVA) using ultrasonography is reported; however, reports related to the effectiveness of using ultrasonography in increasing the success rate for visible and palpable veins is limited. Furthermore, according to a previous study, first attempt success in catheterization contributes to low catheter failure incidence. Thus, we developed a catheterization method using ultrasonography for peripheral veins including visible and palpable veins. This study investigates the effectiveness of ultrasonography use in improving the success rate of catheterization and preventing the catheter failure for peripheral veins including visible and palpable veins. Adult inpatients were recruited. Trained nurses inserted intravenous catheters using ultrasonography. Ultrasonography was used for all vein assessment, target vein selection, and puncturing (i.e. target point selection and/or needle guidance), regardless of the target vein's visibility or palpability. Catheters with over a 24-h dwelling time were followed for catheter failure incidence. Thirty-one patients were recruited, and they required 34 catheterizations. Total number of catheterization attempts were 39. Of the peripheral veins, 51.3% (20/39) were visible and palpable, 48.7% (19/39) were DIVA. The rate of successful intravenous cannulation was 29 of 34 (85.3%) after one attempt and 4 of 34 (total 97.0%) after two attempts. The catheterization failure incidence was 3.2% (1/31) in the catheter that had an over 24-h dwelling time. Using ultrasonography to all target veins might have contributed to higher success rates of catheterization and extremely low incidence of catheter failure based on objective findings. Selecting the vein with larger diameters and healthy tissue as puncture point and showing center of vessel lumen clearly using ultrasonography might have been contributed the results.

Farklı Vasküler Giriş Yollarında Tünelli Hemodiyaliz Kateterlerinin Değerlendirilmesi

Objective: To determine the patency rates and reasons for failure using different access routes for tunneled hemodialysis catheters. &#x0D; Methods: The records of patients who underwent insertion of 14 French tunnelled hemodialysis catheters were retrospectively analyzed. Catheter patency survival was demonstrated using Kaplan-Meier survival curve. Catheter failure and exchange reasons were evaluated. &#x0D; Results: One hundred and six patients underwent 474 catheter exchanges (mean/patient 4.47±1.62). Access was via right internal jugular vein (IJV) n=40, left IJV n=23, right femoral vein (FV) n=18, left FV n=11 and transhepatic vein n=14. The causes of catheter failure and exchange were: catheter-associated infection, catheter thrombosis, fibrin sheath and catheter tip malposition. Mean primary and cumulative catheter patency time was higher in the right IJV group (732 and 1337 days, respectively) compared with the others (p

Cyanoacrylate Securement in Neonatal PICC Use: A 4-Year Observational Study.

Within every neonatal clinical setting, vascular access devices are considered essential for administration of fluids, nutrition, and medications. However, use of vascular access devices is not without danger of failure. Catheter securement adhesives are being evaluated among adult populations, but to date, studies in neonatal settings are scant. This research describes the prevalence of peripherally inserted central catheter failure related to catheter securement before and after the introduction of tissue adhesive for catheter securement. The identified modifiable risks might be used to evaluate efficacy, to innovate neonatal practice and support future policy developments. This was a retrospective observational analysis of routinely collected anonymized intravenous therapy-related data. The study was carried out at the tertiary neonatal intensive care unit (112 beds) of the Women's Wellness and Research Center of Hamad Medical Corporation, Doha, Qatar. The results showed that the use of an approved medical grade adhesive for catheter securement resulted in significantly less therapy failures, compared with the control group. This remains significant after adjusting for day of insertion, gestational age, birth weight, and catheter type. In parallel with currently published international literature, this study's findings support catheter securement with an octyl-based tissue adhesive in use with central venous catheters. When device stabilization is most pertinent, securement with tissue adhesive is a safe and effective method for long-term vascular access among the neonatal population.

Selective Ophthalmic Artery Chemotherapy with Melphalan in the Management of Unilateral Retinoblastoma: A Prospective Study

To determine prospectively the efficacy and to assess potential side effects of melphalan selective ophthalmic artery chemotherapy (SOAC) as first-line treatment for unilateral retinoblastoma. Phase 2 nonrandomized, prospective study. Patients with unilateral retinoblastoma group B, C, or D of the International Classification for Intraocular Retinoblastoma (IRC). Group D eyes with massive vitreous seeding were not eligible. Melphalan SOAC associated with diode laser thermotherapy, cryotherapy, or both at 4-week intervals (3-6 cycles). For persistent vitreous seeding, intravitreal melphalan chemotherapy also was used. The primary outcome was globe preservation rate. Secondary outcomes were tumor relapse rate, occurrence of ocular or systemic adverse events, and measurement of the dose area product (DAP). Between 2012 and 2017, 39 patients (39 eyes) with unilateral retinoblastoma were included prospectively. Three included patients did not receive SOAC (2 catheterization failures and 1 case of viral syndrome) and were considered failures. At diagnosis, IRC groups for the 36 treated patients were: B, n= 4 (11%); C, n= 13 (36%); and D, n= 19 (53%); median age was 21.5 months (range, 3.2-61.6 months). Median number of SOAC cycles was 3.9 (range, 1-6 cycles), and median melphalan dose was 4.9 mg/procedure. The median DAP was 1.24 Gy.cm2/procedure. Median follow-up was 63 months (range, 34-93 months). SOAC was associated with local treatments for 31 patients (86%): diode laser thermotherapy for all of them and cryotherapy or intravitreal chemotherapy for 10 (32%) and 9 patients (25%), respectively. SOAC treatment was interrupted in 5 patients because of severe ophthalmic (ptosis, n= 2; retinal ischemia, n= 2) or systemic (hypotension, n= 1) adverse events. At the cutoff date analysis, all patients were alive without metastasis. The 18-month eye preservation rate was 80% (range, 68.6%-94.6%). After a follow-up of at least 30 months, the ocular preservation rate was 69% (n= 24 preservations). This first prospective trial demonstrated that SOAC with melphalan alone as first-line treatment for retinoblastoma is efficient and well tolerated with no metastatic events, although ocular ischemic complications were observed.

Optimizing the Effectiveness of Short Peripheral Catheters.

Hospitalized adult patients often require more than 1 short peripheral catheter (SPC) to complete the prescribed intravenous (IV) therapy attributed to catheter failure and the practice of routinely replacing SPCs. The purpose of this quality improvement project was to increase the number of SPCs that dwell for the complete duration of the IV therapy in hospitalized adult patients using a bundled approach. Implementation of an engineered securement device (ESD), education pertaining to modifiable risk factors, and changing the practice to removal on clinical indication were methods used to reduce the number of SPC insertions and catheter failures. This study was conducted at a rural Midwestern hospital using a convenience sample (N = 405) and an observational, descriptive cohort design in 6 phases between September 2019 and March 2020. After the practice changes, there was a reduction of SPC replacement (24%), catheter failures (24% to 13%), SPCs per patient (M = 2.9-2.2; P = .045), SPC insertions (4000 per year), and catheter-related bloodstream infections (0.26 per 1000 catheter days to 0.0), as well as a significant increase of SPCs remaining in situ (M = 2.6-3.8 days; P < .001), resulting in an estimated cost savings of at least $285,000. The results demonstrated that the risk of failure significantly increased when SPCs were inserted in the wrist (P = .007) and upper arm (P = .026) and significantly reduced when inserted in the forearm (P = .39). Study findings suggest that using an ESD, promoting SPC insertion in the forearm, avoiding the wrist and upper arm, and changing practice to removal when clinically indicated reduced the number of SPC insertions and rate of catheter failures.
