Venous Return01:04

Venous Return

12.6K
The circulatory system plays a crucial role in ensuring the optimal functioning of the human body. One of its critical components is venous return - the process that completes the blood circulation cycle. This article will delve into the concept of venous return, how it works, and its significance to our health.
What is Venous Return?
Venous return refers to the rate at which blood flows back to the heart from the body's peripheral veins. It's an integral part of the circulatory system...

Venous Thrombosis I: Introduction

496
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Venous Thrombosis III: Interprofessional Care

383
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. Patients on bed rest should change positions every two hours and, if not...

Venous Thrombosis IV: Nursing Management

276
Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

354
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Summary

Pediatric venous port placement is technically successful. Left-sided ports increase infection risk, while lower infant weight elevates mechanical complication risk.

Area of Science:

  • Pediatric Surgery
  • Vascular Access Devices
  • Infectious Disease Prevention

Background:

  • Venous port placement is crucial for long-term intravenous access in infants.
  • Complications such as infections and mechanical issues can arise, impacting patient outcomes.
  • Identifying risk factors is essential for optimizing safety in this vulnerable population.

Purpose of the Study:

  • To assess the technical success rate of venous port placement in infants.
  • To determine the incidence of mechanical and infectious complications.
  • To identify risk factors associated with these complications.

Main Methods:

  • Retrospective cohort study of 64 infants (<1 year) undergoing venous port placement.
  • Data collected included patient demographics, placement details, and complication events.
  • Analysis focused on technical success, central catheter-associated bloodstream infections (CCABSIs), and mechanical complications.

Main Results:

  • 100% technical success rate for venous port placement.
  • 13 central catheter-associated bloodstream infections (CCABSIs) occurred (0.63 per 1,000 catheter-days), with 8 requiring removal.
  • Increased risk of CCABSIs with left-sided port placement (RR 3.22) and mechanical complications in the lowest weight quartile (RR 4.37).

Conclusions:

  • Venous port placement in infants achieves high technical success.
  • Left-sided placement is a risk factor for infectious complications (CCABSIs).
  • Lower infant weight is associated with an increased risk of mechanical complications.
