Methods for measuring venous peripherally inserted central catheters in newborns

ABSTRACT Objective: to analyze the results of insertion procedures of Peripherally Inserted Central Catheters in newborns using two measurement methods. Methods: this is a randomized clinical trial, presenting descriptive and exploratory results of variables. It was held at a Neonatal Intensive Care Unit. Data were collected between September 2018 and 2019. The sample analyzed was 88 catheter insertion procedures, distributed in two groups. Study approved by an Institutional Review Board and obtained registration in the country and abroad. Descriptive analysis and logistic regression of data. Results: modified measurement obtained a significant difference for the central catheter tip location. Elective removals and adverse events were not significant between groups; however, poor positioning was related to adverse events. Conclusions: between the two methods analyzed, the modified measurement obtained better results in the proper catheter tip positioning and, consequently, less risk to patients.

Experience of Radiology Technologists Performing Peripherally Inserted Central Catheters (PICC)

Purpose We conducted this study to review our local experience of performing peripherally inserted central catheters by interventional radiology technologists. Materials and Methods This is a retrospective study of peripherally inserted central catheters performed by interventional radiology technologists. These procedures were performed using ultrasound guidance for venous puncture and fluoroscopy or electrocardiography guidance followed by chest X-ray to confirm tip location. Results We reviewed all peripherally inserted central catheters performed in interventional radiology between May 2017 and July 2020. The review process included the success rate, number of venous puncture attempts, method of guidance, procedure time, fluoroscopy time, catheter duration to removal, and complications. Conclusion Interventional radiology technologists can perform peripherally inserted central catheters safely with high success rate. Extending interventional radiology technologists' role to perform peripherally inserted central catheters allow interventional radiologists to do more complex procedures. This enhances the workflow, increases the interventional radiology team efficiency, and improves the waiting time.

Peripherally Inserted Central Catheters: Evaluation of Diluted Lipid Emulsion as Lubricant for Improved Guidewire Removal in a Neonatal Population.

Background: Medical management of neonates is often predicated upon safe and reliable vascular access which may be related to physiological monitoring, medical treatment, supportive therapy and diagnostic or procedural purposes. For this, peripherally inserted central catheters (PICCs) are deemed safe to provide vascular access and infusion related therapy in the neonatal intensive care setting. Purpose: PICCs are associated with a reduced incidence of complications compared to short peripheral catheters. Despite a reduced complication rate, the impact for the patient has to be considered severe. Difficult PICC guidewire removal during the insertion procedure is known to cause catheter damage, resulting in leakage or breakage of the catheter itself. The aim of this study was to assess and compare the incidence of therapy failure related to the use of preflush fluids (normal saline (NSS) versus diluted lipid solution(DLS)) used before PICC guidewire removal. Method and Setting: This was a retrospective observational study and performed on the Neonatal Intensive Care Unit (NICU) of the Women’s Wellness and Research Centre, Hamad Medical Corporation, Qatar. The single site study included 507 neonates who required intravenous therapy. Results: The results show that the use of a diluted lipid preflush 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.Conclusion: DLS preflush demonstrated a benefit over the use of a NSS preflush to enhance PICC guidewire removal in patients admitted to the NICU. The risk for the development of maintenance-related complications leading to premature removal of the device, decreased significantly if the preflush DLS was used. During the study period no known complications related to the used lipid solution were identified. Implications for Practice and Research: This study is the first of its kind ever published in international literature and supports the enhancement of guidewire removal by using a diluted lipid preflush. When the requirement for vascular access is most pertinent, using a diluted lipid preflush is a safe and effective method to remove the guidewire in order to facilitate long-term vascular access amongst the neonatal population.
