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

Abstract

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.
