Insights

Routine preprocedural bloodwork is not necessary before elective central venous access device (CVAD) removal in children without bleeding disorders. Bleeding complications are rare and not linked to bloodwork results.

Area of Science:

  • Pediatric Interventional Radiology
  • Vascular Access Management
  • Clinical Pathology

Background:

  • Central venous access devices (CVADs) are crucial for pediatric patient care.
  • Routine preprocedural bloodwork is often performed before CVAD removal.
  • The necessity of this testing for elective removals is debated.

Purpose of the Study:

  • To evaluate the clinical utility of routine preprocedural bloodwork.
  • To assess its impact on bleeding complications during elective CVAD removal in children.

Main Methods:

  • Retrospective review of 802 elective CVAD removals (tunneled catheters and ports) from 2009-2013.
  • Exclusion of cases with infection, malfunction, concurrent procedures, or bleeding dyscrasias.
  • Analysis of preprocedural hemoglobin, platelet count, PTT, and INR.

Main Results:

  • 6.1% (49/802) of patients experienced bleeding complications.
  • Most complications (44/49) occurred despite normal bloodwork.
  • No statistically significant difference in bleeding rates between normal and abnormal bloodwork groups (P=.7740).

Conclusions:

  • Routine preprocedural bloodwork is unnecessary for elective CVAD removal in pediatric patients without bleeding disorders.
  • Low incidence of postprocedural bleeding is not predicted by routine blood tests.
  • Streamlining CVAD removal protocols can be considered.

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Pre-Procedural Guidelines for Assessing Blood Pressure

Accurate blood pressure assessment is crucial for diagnosing and managing various health conditions. To ensure the reliability of these measurements, healthcare professionals must adhere to standardized pre-procedural guidelines. These guidelines enhance patient safety and improve the overall quality of healthcare. The following steps are essential for obtaining accurate and consistent blood pressure readings, from using the appropriate tools to ensuring effective communication with the...

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences.

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...
