Transthoracic intracardiac catheters in pediatric cardiac patients: A single-center experience

Infection Associated With Invasive Devices in Pediatric Health Care: A Meta-analysis

CONTEXT

Indwelling invasive devices inserted into the body for extended are associated with infections.

OBJECTIVE

This study aimed to estimate infection proportion and rates associated with invasive devices in pediatric healthcare.

DATA SOURCES

Medline, CINAHL, Embase, Web of Science, Scopus, Cochrane CENTRAL, clinical trial registries, and unpublished study databases were searched.

STUDY SELECTION

Cohort studies and trials published from January 2011 to June 2022, including (1) indwelling invasive devices, (2) pediatric participants admitted to a hospital, (3) postinsertion infection complications, and (4) published in English, were included.

DATA EXTRACTION

Meta-analysis of observational studies in epidemiology guidelines for abstracting and assessing data quality and validity were used.

MAIN OUTCOMES AND MEASURES

Device local, organ, and bloodstream infection (BSIs) pooled proportion and incidence rate (IR) per-1000-device-days per device type were reported.

RESULTS

A total of 116 studies (61 554 devices and 3 632 364 device-days) were included. The highest number of studies were central venous access devices associated BSI (CVAD-BSI), which had a pooled proportion of 8% (95% confidence interval [CI], 6-11; 50 studies) and IR of 0.96 per-1000-device-days (95% CI, 0.78-1.14). This was followed by ventilator-associated pneumonia in respiratory devices, which was 19% (95% CI, 14-24) and IR of 14.08 per-1000-device-days (95%CI, 10.57-17.58).

CONCLUSIONS

Although CVAD-BSI and ventilator associated pneumonia are well-documented, there is a scarcity of reporting on tissue and local organ infections. Standard guidelines and compliance initiatives similar to those dedicated to CVADs should be implemented in other devices in the future.

Device Related Thrombosis and Bleeding in Pediatric Health Care: A Meta-analysis

CONTEXT

The risk of invasive device-related thrombosis and bleeding contributes to morbidity and mortality, yet their prevalence by device-types is poorly understood.

OBJECTIVES

This study aimed to estimate pooled proportions and rates of thrombotic and bleeding complications associated with invasive devices in pediatric health care.

DATA SOURCES

Medline, CINAHL, Embase, Web of Science, Scopus, Cochrane CENTRAL, clinical trial registries, and unpublished study databases were searched.

STUDY SELECTION

Cohort studies and trials published from January 2011 to June 2022, including (1) indwelling invasive devices, (2) pediatric participants admitted to a hospital, (3) reporting thrombotic and bleeding complications, and (4) published in English, were included.

DATA EXTRACTION

Meta-analysis of observational studies in epidemiology guidelines for abstracting and assessing data quality and validity were used.

MAIN OUTCOMES AND MEASURES

Device-specific pooled thromboses (symptomatic, asymptomatic, unspecified) and bleeding (major, minor).

RESULTS

Of the 107 studies, 71 (66%) focused on central venous access devices. Symptomatic venous thromboembolism in central venous access devices was 4% (95% confidence interval [CI], 3-5; incidence rate 0.03 per 1000 device-days, 95% CI, 0.00-0.07), whereas asymptomatic was 10% (95% CI, 7-13; incidence rate 0.25 per 1000 device-days, 95% CI, 0.14-0.36). Both ventricular assist devices (28%; 95% CI, 19-39) and extracorporeal membrane oxygenation (67%; 95% CI, 52-81) were often associated with major bleeding complications.

CONCLUSIONS

This comprehensive estimate of the incidence and prevalence of device-related thrombosis and bleeding complications in children can inform clinical decision-making, guide risk assessment, and surveillance.

Right Atrial Lines as Primary Access for Postoperative Pediatric Cardiac Patients

To characterize the use of right atrial lines (RALs) as primary access in the postoperative care of neonatal and pediatric patients after cardiothoracic surgery and to identify risk factors associated with RAL complications. Observational retrospective cohort study in pediatric cardiac patients who underwent RAL placement in a tertiary children's hospital from January 2011 through June 2018. A total of 692 children with congenital heart disease underwent 815 RAL placements during the same or subsequent cardiothoracic surgeries during the study period. Median age and weight were 22 days (IQR 7-134) and 3.6 kg (IQR 3.1-5.3), respectively. Neonates accounted for 53.5% of patients and those with single-ventricle physiology were 35.4%. Palliation surgery (shunts, cavo-pulmonary connections, hybrid procedures, and pulmonary artery bandings) accounted for 38%. Survival to hospital discharge was 95.5%. Median RAL duration was 11 days (IQR 7-19) with a median RAL removal to hospital discharge time of 0 days (IQR 0-3). Thrombosis and migration were the most prevalent complications (1.7% each), followed by malfunction (1.4%) and infection (0.7%). Adverse events associated with complications were seen in 12 (1.4%) of these RAL placements: decrease in hemoglobin (n = 1), tamponade requiring pericardiocentesis (n = 3), pleural effusion requiring chest tube (n = 2), and need for antimicrobials (n = 6). Multivariable logistic regression showed that RAL duration (OR 1.01, p = 0.006) and palliation surgery (OR 2.38, p = 0.015) were significant and independent factors for complications. The use of RALs as primary access in postoperative pediatric cardiac patients seems to be feasible and safe. Our overall incidence of complications from prolonged use of RALs remained similar or lower to that reported with short-term use of these lines. While RAL duration and palliation surgeries seemed to be associated with complications, severity of illness could be a confounding factor. A prospective assessment of RAL complications may improve outcomes in this medically complex population.

Transthoracic intracardiac catheters in perioperative management of pediatric cardiac surgery patients: a single-center experience

BACKGROUND

Transthoracic intracardiac catheters inserted under direct vision in the pulmonary artery and left atrium during cardiac surgery play major roles in the management of patients with complex congenital heart disease. We aimed to analyze the utility of transthoracic intracardiac catheters in the perioperative management of pediatric cardiac surgery patients and review catheter-related morbidity.

METHODS

The computerized register of all pediatric cardiac surgery patients in whom transthoracic intracardiac catheters were inserted from 2012 to 2019 in a tertiary referral center were reviewed.

RESULTS

Transthoracic pulmonary artery and left atrial catheters were inserted in 89 and 71 patients, respectively. The most common indications for pulmonary artery and left atrial catheters were total anomalous pulmonary venous connection (52%) and total cavopulmonary connection (58%) respectively. The most common reason for elevated pulmonary artery and left atrial pressure after cardiopulmonary bypass was left ventricular dysfunction. Transthoracic pulmonary artery catheters helped in diagnosing pulmonary hypertensive crisis (29%), surgical decision-making (14%), and ventilator therapy (16%). Left atrial catheters helped in the diagnosis of left ventricular dysfunction (54%). The incidence of morbidity was 8.9% for transthoracic pulmonary artery catheters and 9.8% for left atrial catheters.

CONCLUSION

Transthoracic pulmonary artery catheters help in the diagnosis and management of pulmonary hypertensive crisis, for making perioperative surgical decisions, and during ventilator therapy. Transthoracic left atrial catheters help in the diagnosis of left ventricular dysfunction in the perioperative period. The diagnostic and treatment benefits provided by transthoracic intracardiac catheters outweigh the minor adverse events, supporting their continued use in the perioperative period.

Holding and Mobility of Pediatric Patients With Transthoracic Intracardiac Catheters

BACKGROUND

Nursing care of pediatric patients after cardiac surgery consists of close hemodynamic monitoring, often through transthoracic intracardiac catheters, requiring patients to remain on bed rest and limiting holding and mobility.

OBJECTIVES

The primary aim of this quality improvement project was to determine the feasibility of safely mobilizing pediatric patients with transthoracic intracardiac catheters out of bed. Once feasibility was established, the secondary aim was to increase the number of days such patients were out of bed.

METHODS AND INTERVENTIONS

New standards and procedures were implemented in July 2015 for pediatric patients with transthoracic intracardiac catheters. After initiation of the new policies, complications were tracked prospectively. Nursing documentation of activity and positioning for all patients with transthoracic intracardiac catheters was extracted from electronic health records for 2 fiscal years before and 3 fiscal years after the new policies were implemented. The Cochran-Armitage test for trend was used to determine whether patterns of out-of-bed documentation changed over time.

RESULTS

A total of 1358 patients (approximately 250 to 300 patients each fiscal year) had activity and positioning documented while transthoracic intracardiac catheters were in place. The Cochran-Armitage test for trend revealed that out-of-bed documentation significantly increased after the new policies and procedures were initiated (P < .001). No major complications were noted resulting from patient mobility with transthoracic intracardiac catheters.

CONCLUSION

Pediatric patients with transthoracic intracardiac catheters can be safely held and mobilized out of bed.

Multivariate analysis on complications of central venous access devices in children with cancer and severe disease influenced by catheter tip position and vessel insertion site (A STROBE-compliant study)

CONTEXT

Reliable long-term central venous access device (CVAD) is essential for the management of pediatric patients with cancer or chronic diseases. However, there is no general consensus for optimal catheter tip location and vessel insertion site in children.

OBJECTIVE

This single center study analyzes the risk of complications associated with long-term upper body CVAD and evaluates them with respect to catheter tip location as well as vessel insertion site.

DESIGN

Pediatric patients who received long-term upper body CVAD from January 2008 through April 2017 and underwent radiographic documentation of the tip location were retrospectively included in the study. Data on demographics, catheter tip location on chest x-ray, intraoperative vessel insertion sites and postoperative complications were analyzed. Catheter tip location was categorized as "high" (above the right mainstem bronchus), "medium" (at the level of the bronchus), and "low" (below the right mainstem bronchus). Distance to the carina was measured as well.

RESULTS

A total of 396 patients, 74.7% suffering from cancer were included in our study (mean age 6.3 ± 0.3 years). Complications occurred in about one fourth of all patients. Catheter-related blood stream infections (BSI) (n = 40, 36.4%) were most prevalent, but catheter tip position or vessel insertion site had no impact on the risk of infections. Dislodgement (n = 27, 24.6%) and occlusion (n = 11, 10.0%) were more frequent in "high" positioned catheter tips. While there was one patient who developed arrhythmia, no case of cardiac perforation, and in particular, no catheter-related death was recorded in our series. The vessel insertion site seemed to have no influence on the complication frequency of CAVDs.

CONCLUSION

The catheter tip position seems to have an impact on the catheter-related complication profile in children. To avoid complications, we recommend avoiding a "high" localization of the catheter tip above the right main bronchus. "Low" catheter tip placement was associated with the lowest dislocation rate. Given the overall low complication rate, insertion and use of CVADs in children can generally be considered as safe.

Nursing Practice With Transthoracic Intracardiac Catheters in Children: International Benchmarking Study

BACKGROUND

Transthoracic intracardiac catheters are central catheters placed in the operating room at the conclusion of cardiac surgery for infants and children. Complications associated with these catheters (eg, bleeding, migration, premature removal, infection, leakage, and lack of function) have been described. However, no researchers have addressed the nursing management of these catheters in the intensive care unit, including catheter dressing and securement, mobilization of patients, and flushing the catheters, or the impact of these interventions on patients' outcomes.

OBJECTIVES

To internationally benchmark current nursing practice associated with care of infants and children with transthoracic intracardiac catheters.

METHODS

In a cross-sectional, descriptive study of nursing practice in infants and children with transthoracic intracardiac catheters, a convenience sample of bedside and advanced practice nurses was recruited to complete an online survey to benchmark current practice. The survey included questions on criteria for catheter insertion and removal, dressing care, flushing practice, securement, and mobilization of patients.

RESULTS

Transthoracic intracardiac catheters are used by most centers that provide care for infants and children after open heart surgery. A wide range of practices was reported.

CONCLUSIONS

Standardizing the use and care of transthoracic intracardiac catheters can improve the safety and efficacy of their use in infants and children and promote safe and early postoperative mobilization of patients.

Complications of Transthoracic Intracardiac and Central Venous Lines in Neonates Undergoing Cardiac Surgery

Neonates undergoing congenital heart surgery require central venous access for diagnostic information and medication administration. There are multiple options for central access including peripherally inserted central catheters, umbilical, central venous, and transthoracic intracardiac lines. We retrospectively identified all patients younger than 30 days who underwent cardiac surgery in a 1-year period. Data were collected on demographic and medical characteristics, adverse events, pre-emptive transfusion of blood products prior to line removal, and transfusion of blood products following removal of transthoracic intracardiac lines and central venous lines. In our cohort of 124 neonates, 176 transthoracic intracardiac lines were placed in 113 patients. Eighty-two patients had pre-existing central venous access including 35 umbilical venous lines, 21 PICC lines, and 18 CVLs. Ninety-eight patients received a CVL in the operating room by anesthesia. Five patients were transfused to correct laboratory derangement prior to transthoracic intracardiac line removal. Transfusion of packed red blood cells (pRBC) occurred after transthoracic intracardiac line removal in 25 patients. Thrombus formation was present in one patient with a transthoracic intracardiac line and three patients with CVLs. One patient underwent surgical intervention for repositioning of a transthoracic intracardiac line. There were no cases of cardiac arrest, extracorporeal life support, or deaths attributable to lines. In this cohort, transthoracic intracardiac lines were generally safe. There were very few complications of thrombus, infection, or requirement for surgical intervention; however, transfusion of pRBCs following transthoracic intracardiac line removal occurred in 20% of patients.
