Insights

Mechanical complications affect 17% of central venous access devices (CVADs) in children, with younger age and lower weight increasing risk. Implantable ports show fewer issues than Hickman lines.

Area of Science:

  • Pediatric Surgery
  • Medical Devices
  • Vascular Access

Background:

  • Mechanical complications of central venous access devices (CVADs) in pediatric patients are not well understood.
  • Identifying risk factors and rates is crucial for improving patient outcomes.

Purpose of the Study:

  • To quantify the incidence of mechanical complications in pediatric CVADs.
  • To investigate the mechanisms and associated risk factors for these complications.

Main Methods:

  • Retrospective review of 317 CVADs inserted in children under 18 between 2016-2021.
  • Statistical analysis including Fisher's exact test, chi-squared test, and logistic regression.
  • Data categorized by complication type, device type, patient age, and weight.

Main Results:

  • Overall, 17% of CVADs experienced mechanical complications within a median of <6 months post-insertion.
  • Fracture (6%), CVAD migration (4.4%), and occlusion (4.4%) were the most common complications.
  • Younger age and lower weight were significant risk factors (p < 0.0001). Hickman lines had a higher complication rate (26.3%) than implantable ports (13.3%, p=0.008).

Conclusions:

  • Mechanical complications are a significant concern in pediatric CVADs, occurring in 17% of cases.
  • Risk is elevated in younger, lighter children.
  • Implantable port devices demonstrate a lower incidence of mechanical complications compared to Hickman lines, suggesting they may be a safer option in certain pediatric populations.

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,...

Hemodialysis I: Introduction01:25

Hemodialysis I: Introduction

Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

Endocarditis IV: Nursing Management

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Hemodialysis II: Procedure and Complications

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,...
