Outcomes associated with peripherally inserted central catheters in hospitalised children: a retrospective 7-year single-centre experience

Adverse Events from Fluoroscopic versus Portable Placement of Peripherally Inserted Central Catheters and Central Venous Catheters in Pediatric Patients

PURPOSE

To compare the outcomes of fluoroscopic versus portable placement of peripherally inserted central catheters (PICCs) and central venous catheters (CVCs) in pediatric patients.

MATERIALS AND METHODS

This is a single-center, retrospective review of 346 upper-extremity PICC placements (286 fluoroscopic and 60 portable; mean age, 9.83 years [SD ± 5.58]; 49.1% female) and 138 tunneled femoral CVC placements (56 fluoroscopic and 82 portable; mean age, 0.23 years [SD ± 0.36]; 57.0% female). Portable placements used mobile plain-film radiography. All lines were placed by board-certified interventional radiologists.

RESULTS

Fluoroscopic PICC placements had a lower procedure time (43.9 vs 57.9 minutes; P < .001), radiation dosage (342 vs 590 mGy·cm2; P < .001), incidence of technical failure (0% vs 3.3%; P = .029), and incidence of catheter malfunction (1.7% vs 12.1%; P < .001) compared with portable PICC placements. Fluoroscopic CVC placements had a lower procedure time (42.6 vs 54.8 minutes; P < .001) and radiation dosage (63.8 vs 405 mGy·cm2; P < .001) compared with portable CVC placements. No technical failures were found in either CVC groups and the difference was nonsignificant for catheter malfunction (0% vs 7.3%; P = .081). Fluoroscopic placements of PICCs and CVCs had a lower incidence rate of central line-associated bloodstream infection compared with portable placements (0.71 vs 2.22 cases per 1,000 line-days; P = .046). Overall, fluoroscopic placements of PICCs and CVCs had fewer adverse events compared with portable placements (3.2% vs 14.8%; P < .001). Portable procedure setting was the only significant factor associated with adverse events (odds ratio, 33.77; 95% CI, 4.56-757.01).

CONCLUSIONS

Fluoroscopic placements of PICCs and CVCs are associated with lower procedure time, radiation dose, and risk of adverse events compared with portable placements in pediatric patients.

Salvage strategy for long-term central venous catheter-associated Staphylococcus aureus infections in children: a multi-centre retrospective study in France

OBJECTIVES

Catheter removal is recommended in adults with Staphylococcus aureus central-line-associated bloodstream infection (CLABSI) but is controversial in children with long-term central venous catheters (LTCVC). We evaluated the occurrence of catheter salvage strategy (CSS) in children with S. aureus LTCVC-associated CLABSI and assessed determinants of CSS failure.

METHODS

We retrospectively included children (<18 years) with an LTCVC and hospitalized with S. aureus CLABSI in eight French tertiary-care hospitals (2010-2018). CSS was defined as an LTCVC left in place ≥72 h after initiating empiric antibiotic treatment for suspected bacteraemia. Characteristics of patients were reviewed, and multi-variable logistic regression was performed to identify factors associated with CSS failure (i.e., persistence, recurrence or complications of bacteraemia).

RESULTS

We included 273 episodes of S. aureus LTCVC-associated CLABSI. CSS was chosen in 194 out of 273 (71%) cases and failed in 74 of them (38%). The main type of CSS failure was the persistence of bacteraemia (39 of 74 cases, 53%). Factors independently associated with CSS failure were: history of catheter infection (adjusted odds ratio (aOR) 3.18, 95% confidence interval (CI) 1.38-7.36), CLABSI occurring on an implantable venous access device (aOR 7.61, 95% CI 1.98-29.20) when compared with tunnelled-cuffed CVC, polymicrobial CLABSI (aOR 3.45, 95% CI 1.25-9.50), and severe sepsis at the initial stage of infection (aOR 4.46, 95% CI 1.18-16.82).

CONCLUSIONS

CSS was frequently chosen in children with S. aureus LTCVC-associated CLABSI, and failure occurred in one-third of cases. The identified risk factors may help clinicians identify children at risk for CSS failure.

Catheter-related complications in onco-hematologic children: A retrospective clinical study on 227 central venous access devices

BACKGROUND

The use of central venous access devices (CVADs) is of paramount importance to safely deliver antiblastic and support therapies in children with cancer. Though, in pediatric patients, as much as in adults, CVADs are potentially associated with severe complications which may result in unscheduled interruption of therapy, hospitalization, increased morbidity/mortality, and increased cost of care.

METHODS

We have reviewed retrospectively our experience with CVADs in children with solid tumors and hematologic diseases, with the purpose of verifying if the adoption of well-defined insertion and maintenance bundles might be effective in reducing catheter-related complications, and in particular catheter-related thrombosis.

RESULTS

A total of 227 CVADs were analyzed: 175 peripherally inserted central catheters (PICCs), 50 centrally inserted central catheters (CICCs), and 2 femorally inserted central catheters. All CVADs were non-valved, non-cuffed power injectable polyurethane catheters; 81% were tunneled. Median dwelling time of CVADs was 172 days, for a total number of 39,044 catheter days. A very low incidence of both symptomatic catheter-related thrombosis (0.9%) and catheter-related blood stream infection (0.56 episodes per 1000 catheter days) was found. Unscheduled removal or guidewire replacement because of mechanic complications occurred in 15.7% of CVADs. There was no difference in terms of complications between PICCs and CICCs or between tunneled and non-tunneled catheters.

CONCLUSIONS

Our experience with CVADs in oncologic and hematologic children suggests that catheter-related complications may be minimized by the adoption of appropriate insertion and maintenance bundles.

Placement of peripherally inserted central catheter through upper versus lower limb vein in neonates: A meta-analysis of randomized controlled trials

AIM

Peripherally inserted central catheter (PICC) is an important treatment for the drug and nutrition administration in neonates. We aimed to evaluate the effects and safety of PICC placement through upper versus lower limb vein in neonates, to provide insights into the clinical PICC nursing care.

DESIGN

A meta-analysis.

METHODS

We searched the Cochrane Library, Web of Science, PubMed, Science Direct, China national knowledge infrastructure, Wanfang Data Knowledge Service Platform, China Weipu Database, China Biomedical Literature Database for published randomized controlled trials (RCTs) on the placement of PICC via upper limb and lower limb venipuncture. Two reviewers independently evaluated and cross-checked the quality of the included studies in accordance with the quality standards of the Cochrane Manual. We used RevMan 5.3 software for statistical processing.

RESULTS

A total of 12 RCTs were included in this meta-analysis. Meta-analysis indicated that compared with upper limb veins, PICC insertion through lower limb veins is beneficial to increase the one-time puncture success rate (relative risk [RR]  =  0.73, 95% confidence interval [CI]: 0.68-0.79) and the indwelling time (mean difference [MD] =  -3.60, 95% CI: -5.35 to -1.86), reduce the operation time (MD =  10.37, 95% CI: 7.48-13.26), estimated bleeding volume (MD =  0.55, 95% CI: 0.34-0.75), incidence of catheter ectopia (RR  =  2.46, 95% CI: 1.81-3.35), PICC-associated infection (RR  =  2.82, 95% CI: 1.65-4.83), exosmosis (RR  =  2.45, 95% CI: 1.49-4.04, p < .001) and phlebitis (RR  =  1.40, 95% CI: 1.03-1.90). No significant difference in the Incidence of catheter obstruction between the upper and lower limb veins (RR  =  1.20, 95% CI: 0.73-1.97, p = .48) was found.

PUBLIC CONTRIBUTION

There are certain advantages in neonatal PICC puncture through the lower limb vein. The lower limb vein may be the preferred choice for neonatal PICC puncture.

Fifteen years of central catheter applications and outcomes in intensive care patients: A single-center pediatric experience

BACKGROUND

To investigate the clinical outcome of central line placement in the pediatric age group and to evaluate the risk factors for central line-associated bloodstream infection (CLABSI).

METHODS

We retrospectively examined the outcomes and CLABSI risk factors of pediatric patients aged 0-17 years admitted to intensive care units who had central catheters placed between January 2005 and December 2020.

RESULTS

Of the 2718 catheter admissions, 1502 catheter admissions were eligible for the regression and other outcome analyses. Fifty-seven percent of the study group were umbilical artery and vein catheters and 43% were other central catheter admissions, including ultrasound-guided catheter admissions. Logistic regression analysis showed us that right internal jugular vein (RIJV) (OR = 1.5, 95% CI = 1.15-2.02, p = 0.030) was the insertion site and ultrasound-guided interventional radiology catheter placement was the technique (OR = 1.7, 95% CI = 1.07-2.90, p = 0.024), duration of catheter stay (OR = 1.07, 95%CI = 1.06-1.08, p < 0.001), catheter placement in patients older than 2 years (OR = 2.42, 95% CI = 1.69-3.45, p < 0.001), were risk factors for CLABSI.

CONCLUSION

Although CLABSI has variable risk factors, the most important risk factor seems to be the length of catheter stay.

Cannulation via the external jugular vein--An alternative to conventional peripherally inserted central catheterisation for paediatric patients

PURPOSE

This study aimed to describe a peripherally inserted central catheterisation (PICC) for paediatric patients with inaccessible access and a high risk of general anaesthesia (GA).

METHODS

This was a retrospective observational study involving all paediatric inpatients who performed the PICC via an EJV approach without GA between September 2014 and September 2021 in a provincial key clinical speciality.

RESULTS

A total of 290 EJV line placement attempts were performed, and 29 were excluded due to missing placement results, resulting in a sample size of 261. The anatomical localisation, punctures, and catheterisation success rates for this practice were 100%, 100%, and 90.04%, respectively. The placement success rate in children younger than one year was 93.75% (45/48). The median line duration of use was 19 days, with a median length of catheter insertion of 13 cm. The most common complications were catheter malposition (n = 20) and dislodgement (n = 7).

CONCLUSION

The PICC via an EJV approach without GA is a feasible and safe practice with acceptable success and complication rates, and low costs. It might be an attractive alternative for obtaining central vascular access for paediatric patients.

Risk factors for peripherally inserted central venous catheter-related complications in children: A retrospective cohort study

To explore the risk factors for peripherally inserted central venous catheter (PICC)-related complications in children. This retrospective study analyzed data collected from electronic medical records. A total of 584 patients with indwelling PICC treated between January 2019 and August 2021 were included in this study. According to the occurrence of PICC-related complications, the patients without PICC-related complications were included in the control group (n = 538) and those with PICC-related complications were included the observation group (n = 46). The risk factors for PICC-related complications were analyzed. Of the 584 patients with PICCs, 46 (7.88%) had PICC-related complications. Univariate analysis revealed significant differences in venipuncture (P < .001), oozing of blood from the puncture point (P < .001), indwelling time (P < .001), intravenous nutrient solution (P < .001), and catheter type (P = .003). Complications were used as dependent variables. The independent variables were vein puncture, blood oozing at the puncture point, indwelling time, intravenous nutrient solution, and catheter type. Multivariate logistic regression analysis revealed that the vein puncture (odds ratio [OR] 10.115, 95% confidence interval [CI] 5.034-20.323, P < .001), puncture point blood oozing (OR 9.217, 95% CI 3.860-22.004, P < .001), indwelling time (OR 6.390, 95% CI 3.527-10.972, P = .005), intravenous nutrient solution (OR 2.593, 95% CI 1.675-4.015, P < .001), and catheter type (OR 8.588, 95% CI 2.048-19.095, P = .013) were all risk factors for PICC-related complications in children. Venipuncture, oozing of blood from the puncture point, indwelling time, intravenous nutrient solution, and catheter type are risk factors for PICC-related complications in children. Significant attention should be paid to whether the puncture point is bleeding, the presence or absence of an intravenous nutrient solution, duration of catheterization, type of catheterization, and venipuncture. Additionally, preventive nursing measures should be implemented as soon as possible to reduce the risk of complications related to peripheral PICC.

Indications, Measurements, and Complications of Ten Essential Neonatal Procedures

About 10% of newborns require some degree of assistance to begin their breathing, and 1% necessitates extensive resuscitation. Sick neonates are exposed to a number of invasive life-saving procedures as part of their management, either for investigation or for treatment. In order to support the neonates with the maximum possible benefits and reduce iatrogenic morbidity, health-care providers performing these procedures must be familiar with their indications, measurements, and potential complications. Hence, the aim of this review is to summarise ten of the main neonatal intensive care procedures with highlighting of their indications, measurements, and complications. They include the umbilical venous and arterial catheterizations and the intraosseous line which represent the principal postnatal emergency vascular accesses; the peripherally inserted central catheter for long-term venous access; the endotracheal tube and laryngeal mask airway for airway control and ventilation; chest tube for drainage of air and fluid from the thorax; and the nasogastric/orogastric tube for enteral feeding. Furthermore, lumber puncture and heel stick were included in this review as very important and frequently performed diagnostic procedures in the neonatal intensive care unit.

Bedside Durable Tunneled Femoral Central Venous Catheter is Feasible and Safe in High-Risk Infants in the Pediatric Cardiac Intensive Care Unit

OBJECTIVE

Ultrasound (US)-guided durable tunneled femoral central venous catheters (TF-CVCs) are a safe central venous access option in infants and neonates. Studies have shown, however, that femoral central venous access has the potential for high central line-associated bloodstream infection (CLABSI) rates with a significant increase in risk for line-related thrombosis. Our aims were to describe the bedside insertion technique and evaluate the safety and complication rates of TF-CVCs in high-risk, young, pediatric cardiac intensive-care unit (PCICU) population.

DESIGN

A retrospective observational cohort study.

SETTING

University affiliated, tertiary-care hospital, PCICU.

PATIENTS

All PCICU patients that underwent bedside TF-CVC insertion were enrolled. Data was collected from the electronic medical record system.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

During April 2016 to October 2021, 103 TF-CVC lines were inserted into 94 pediatric cardiac critical care patients, at the bedside. Patients' characteristics were median (IQR) age of 47.5 days (22.6, 120.5), weight 3.3 kg (2.9, 4.3), 33% prevalence of genetic anomalies, need for ECMO support in 20.4%, and STAT category 4-5 in 53.4%. All procedures were performed by intensivists. There were no immediate procedure-related complications. TF-CVCs were inserted on average on post-operative day (POD) 14, median line indwell duration was 25 days (16.3, 42.3) and total TF-CVC dwell duration for the entire cohort of 3442.7 days. During the study period eight CLABSI events were recorded (2.3/1000 line-days). Line obstruction rate was 1.16/1000 line-days and six lines were dislodged in the intermediate-care unit. There was no symptomatic line-related thrombosis.

CONCLUSIONS

We show that US-guided durable tunneled femoral central venous catheter (TF-CVC) insertion by an intensivist at the bedside is a technically feasible and safe prolonged central venous access option in critically ill, high-risk infants and neonates in the PCICU.

Risk factors for central venous catheter-related thrombosis in hospitalized children: a single-center a retrospective cohort study

BACKGROUND

This study aimed to explore the risk factors of catheter-related thrombosis (CRT) in children in Southwest China who underwent central venous catheter (CVC) insertion.

METHODS

An observational cohort study was conducted at a single tertiary center in southwest China between November 2019 and February 2020. All patients who received a CVC were enrolled and Doppler-ultrasound examination was performed weekly until CVC removal. All patients in this study were hospitalized and were observed and followed up in this hospital. Patient demographics, medication, biochemical indexes, catheter maintenance practice, activities after CVC placement data were analyzed. The Kaplan-Meier method was used to calculate the incidence of CRT, and the Cox regression model was used to analyze the factors influencing CRT.

RESULTS

A total of 594 children were included in the study, and the median indwelling time was 10 days, with the shortest being 1 day and the longest 60 days. The overall incidence of CRT was 26.60% (158/594), the 15-day cumulative incidence rate was 30.81%, and the 45-day cumulative incidence rate was 46.27%. After 45 days, the incidence of CRT further increased. Age <12 months [hazard ratio (HR), 1.654; 95% confidence interval (CI): 1.171-2.338], use of 20% mannitol or glycerol fructose (HR, 1.593; 95% CI: 1.058-2.398), CVC placement by a pediatric intensive care unit (PICU) doctor (HR, 1.921; 95% CI: 1.347-2.740), placement length ≥9 cm (HR, 1.633; 95% CI: 1.142-2.336), and D-dimer >1.5 mg/L (HR, 1.451; 95% CI: 1.044-2.015) were risk factors for CRT. Limb exercises (HR, 0.660; 95% CI: 0.469-0.929) after placement was a protective factor for CRT.

CONCLUSIONS

The incidence of CRT was higher in children with CVCs, and the key duration of CRT monitoring should be within 15 and 45 days after placement. Patients with age <12 months, using 20% mannitol or glycerol fructose, insertion length ≥9 cm, D-dimer >1.5 mg/L before placement are more likely to happen CVC-CRT than other patient, and it is necessary to be highly vigilant and take preventive measures.

Clinical Characteristics of Venous Thrombosis Associated with Peripherally Inserted Central Venous Catheter in Premature Infants

Background: This study aimed to analyze clinical characteristics and risk factors for peripherally inserted central catheter (PICC) placement in premature infants. Materials: This study included seven premature infants who were hospitalized in the neonatal intensive care unit (NICU) of Peking University Third Hospital from 1 January 2014–30 June 2021, and suffered PICC-related venous thrombosis. The control group included premature infants (n = 56) matched (1:8) by the following: Did not experience venous thrombosis; born with a similar gestational age (±2 w), birth weight (±200 g); and received PICC catheterization in the same period (±4 w). Clinical neonatal data were collected through the hospital electronic medical record system and analyzed using SPSS version 23. Results: The incidence of PICC-related thrombus was 0.23% (7/3043. Univariate analysis revealed that, compared to the non-thrombotic group, mothers in the thrombosis group had autoimmune diseases (χ² = 9.844, p = 0.030) and used anticoagulative drugs during pregnancy (χ² = 8.036, p = 0.025). The corrected gestational age when PICC-related thrombosis occurred in the thrombosis group was 32 + 6 (30 + 1, 34 + 1) weeks. The average time from catheter placement to thrombosis was 5 (1, 12) days. Among infants, 85.7% (6/7) experienced deep vein thrombosis, of which four were in the lower extremity veins; three occurred within 2 days after central venous catheter extubation, and four occurred during central venous catheter indwelling. The clinical manifestations of thrombosis include skin edema, color changes, and skin temperature changes in the affected limbs. The seven neonates had normal coagulation at the time of thrombus diagnosis, but D-dimers significantly increased 1–2 days after thrombosis, returning to normal 5–8 days after thrombus. The thrombus persisted for 4.5 (3, 8) days. All seven neonates were treated with low molecular weight heparin calcium anticoagulation for 10 (3, 17) days and recovered completely. Conclusions: PICC-related thrombosis occurred within 1 week after catheter placement, and thrombosis more likely happened in infants whose mothers had autoimmune disease. When this high-risk factor exists and the patient has been intubated for 1 week and has sudden swelling in the intubated limb, venous ultrasound should be performed immediately to diagnose, and treatment should be provided in a timely manner to reduce adverse events.

Retrospective Study of the Application Value Analysis of Ultrasound-Guided Technology in Peripheral Deep Venous Catheterization of Neonates

Objective

To investigate the application value analysis of ultrasound-guided technology in peripheral deep venous catheterization of neonates.

Method

A total of 94 neonates who underwent peripheral deep venous catheterization treatment from March 2020 to August 2021 in our hospital were selected and divided into the study group and the control group according to the simple randomized method, and each group had 47 cases. The control group was performed peripheral deep venous catheterization through X-ray examination, while the study group was performed peripheral deep venous catheterization through ultrasound-guided technology. The catheter placement, catheter retention time and adjustment times, the incidence of complications (limb swelling, pain, fluid leakage, and phlebitis), and the intervention satisfaction of family members were counted.

Results

The success rate of one-time catheterization in the study group was higher than that in the control group, the operation time was shorter than that in the control group, and the amount of bleeding was less than that in the control group. The indwelling time of catheter in the study group was longer than that in the control group, and the number of adjustments was less than that in the control group. The incidence of complications in the study group was lower than that in the control group. The intervention satisfaction of family members in the study group was higher than that in the control group.

Conclusion

Peripheral deep venous catheterization in neonates through ultrasound-guided technology can reduce operation time and blood loss and ensure the success rate of one-time catheterization, resulting in a long indwelling time of catheter, low number of adjustments, and low incidence of complications, which has safety and high intervention satisfaction of family members.

ELABORATION AND VALIDATION OF A TERMINOLOGY SUBSET FOR NEWBORNS WITH CENTRAL VENOUS CATHETERS

ABSTRACT Objective: to elaborate and validate the content of a terminology subset of the International Classification for Nursing Practice, in light of Betty Neuman's theoretical model, for newborns with a Peripherally Inserted Central Catheter. Method: a methodological study carried out according to the guidelines of the Brazilian method for developing International Classification for Nursing Practice terminology subsets, through the following stages: 1) Identification of clinical findings relevant to the Nursing practice; 2) Cross-mapping of the findings identified with the International Classification for Nursing Practice terms, version 2019/2020; 3) Elaboration of the Nursing diagnoses, outcomes and interventions statements, based on Betty Neuman's theoretical model; 4) Validation of the statements' content by expert nurses, using the Delphi Technique in two rounds. The Content Validity Index was used for data analysis, where the statements with Content Validity Index values ≥ 0.80 were validated. Results: 86 clinical findings were identified, allowing for the development and validation of a terminology subset of the International Classification for Nursing Practice, composed of 31 diagnoses/outcomes, categorized according to the levels of intra-personal (3.03%), inter-personal (3.03%) and extra-personal (93.93%) stressors, as well as of 154 Nursing interventions. Conclusion: the elaboration and validation of a terminology subset of the International Classification for Nursing Practice for newborns with a Peripherally Inserted Central Catheter offers support for better targeted provision of care and for quality assistance.

Enlisting Parents to Decrease Hospital-Acquired Central Line-Associated Infections in the Pediatric Intensive Care Unit

Hospital-acquired central line-associated bloodstream infections (CLABSIs) are the leading cause of infections in the pediatric intensive care unit. Bacteria responsible for CLABSIs are spread by health care workers, parents, and families and mitigated by scrupulous attention to hand hygiene and safety prevention strategies. Maintenance bundles are grouped elements, such as hand hygiene, standardized dressing and tubing changes, and aseptic technique for entering a central line, effective in preventing CLABSIs. Nurses can decrease the incidence of CLABSIs by using maintenance bundles and including parents and families in safety prevention strategies."

Trimmed central venous catheters in pediatric cardiac surgery: Does height or weight correlate with the amount trimmed?

BACKGROUND

Due to excess catheter length, pediatric patients undergoing cardiac surgery frequently have the tip of the central venous catheter trimmed while on bypass to obtain optimal catheter positioning.

AIMS

We sought to determine if there is a correlation between the patient's height or weight and the length of catheter removed. Our secondary aim compared the instances of central line-associated bloodstream infections and venous thromboembolisms between the trimmed and untrimmed catheters.

METHODS

This retrospective study included patients having undergone cardiac surgery over a 3-year period who had an 8 cm central venous catheter placed in the right internal jugular vein. Hospital lists of central line-associated bloodstream infections and venous thromboembolisms that occurred were cross referenced with our study patients.

RESULTS

There were 147 cases where the 8 cm central venous catheter was trimmed, which represents 35% of the cases. Of the catheters that were cut, on average 2.17 cm was removed. There is negligible correlation between the length of catheter removed and patient height (r = -.19, p = .021). There is negligible correlation between the length of catheter removed and patient weight (r = -.17, p = .039). There were no instances of central line-associated bloodstream infections or venous thromboembolisms attributed to the trimmed catheters. Of the 273 untrimmed catheters, there were no instances of an infection and one instance of a venous thromboembolism.

CONCLUSION

Right internal jugular 8 cm central venous catheters are trimmed during pediatric cardiac surgery, and there is minimal correlation between the length removed and the patient height or weight. Due to the difficulty in estimating the proper length of a central venous catheter in smaller pediatric patients, placing an 8 cm long catheter in these patients and then trimming the distal tip while on bypass may be the most accurate way to properly position a catheter.

Catheter related thrombosis in hospitalized infants: A neural network approach to predict risk factors

INTRODUCTION

We sought to investigate the predictors of catheter-related thrombosis (CRT) in a cohort of critically ill hospitalized infants and using a novel approach (the artificial neural network - ANN) in combination with conventional statistics to identify/confirm those predictors.

METHODS

We performed a retrospective analysis of all infants with a central or peripherally inserted central venous catheter (CVC/PICC) between 2015 and 2018. ANN was generated to investigate the predictors of CRT. The predictive variables examined in the ANN were age, gender, weight, co-morbid conditions, line type, use of ultrasound (USG), emergent line placement, location of line tip, any major surgical procedures, use of mechanical ventilation, exposure to cardio-pulmonary bypass (CPB), past-history of CVC/PICC, or thrombosis. Binary logistic regression was performed to calculate odds ratios (ORs) and determine which factors were significant in predicting CRT.

RESULTS

Of total of 613 infants, 59.9% of patients had a history of previous CVC or PICC and 12.2% had a history of thrombus as documented by USG in the past three months. CPB exposure was present in 48.1%. The incidence of CRT was 10.7%. Independent predictors of CRT were the line tip in IVC (OR: 2.37, 1.08-5.21, P = 0.032), history of thrombosis (OR: 2.40, 1.16-4.96, P = 0.019), previous CVC/PICC (OR: 2.80, 1.24-6.33, P = 0.014) and exposure to CPB (OR: 2.749, 1.08-6.98, P = 0.034). A sensitivity analysis was performed to determine the normalized importance of each variable used to create the ANN. The most important variables were age (with normalized importance of 100%), history of thrombosis, weight, and exposure to CPB (normalized importance of 68.2%).

CONCLUSIONS

Nearly 1 in 10 infants developed CRT. We found that catheter tip in IVC, exposure to CPB, history of vein thrombosis and history of CVC/PICC placement in the past 3 months are independently associated with a higher risk of CRT in infants by using conventional and neural network methods.

Effect of implementing an Epicutaneo-Caval Catheter team in Neonatal Intensive Care Unit

Background:

Until the 1980s, central vascular access in the Neonatal Intensive Care Unit was predominantly delivered by umbilical catheters and only and if needed by surgical cutdowns or subclavian vein catheterization through blind percutaneous venipuncture. In the early 1980s, epicutaneo-caval catheters were successfully introduced.

Methods:

In our Neonatal Intensive Care Unit, a dedicated team to insert epicutaneo-caval catheters was formally established in January 2017, including 12 neonatologists and 1 neonatal nurse practitioner. A before- versus after-intervention study was designed to determine whether the establishment of the epicutaneo-caval catheter insertion team is associated with increased success rates and a decreased risk of catheter-related complications. Success rates and other catheter-related parameters were traced from 2016 onward. Collected data were analyzed for three consecutive years: 2016, 2017, and 2018.

Results:

The epicutaneo-caval catheter team inserted 1336 catheters over 3 years. Both first prick (from 57.7% to 66.9%; p = 0.023) and overall success (from 81.7% to 97.6%; p < 0.0001) rates significantly improved. In 2018, the number of tunneled or surgically inserted central venous catheters came down to zero (p < 0.0001). Overall catheter-related complications were significantly lower following the epicutaneo-caval catheter team’s establishment (p < 0.0001) while there was no significant decrease noted (p = 0.978) in central line–associated bacterial stream infection rates.

Conclusion:

A dedicated epicutaneo-caval catheter team is a promising intervention to increase success rates and significantly decrease catheter-related complications in Neonatal Intensive Care Unit. Standardizing epicutaneo-caval catheter placement is important; however, standardizing catheter maintenance seems essential to the improvement of central line–associated bacterial stream infection rates.
