Parentral Nutrition: Centeral and Peripheral Parental Nutrition

460
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,...

Summary
This summary is machine-generated.

Multiple attempts to insert umbilical venous catheters (UVCs) in neonatal intensive care units (NICUs) are less likely to achieve central placement and prolong the procedure. First-attempt success is crucial for efficient UVC insertion in neonates.

Area of Science:

  • Neonatal Medicine
  • Pediatric Surgery
  • Medical Device Insertion

Background:

  • Umbilical venous catheters (UVCs) are essential for neonatal intensive care.
  • Optimizing UVC insertion practices is critical for patient outcomes.

Purpose of the Study:

  • To evaluate UVC insertion practices in tertiary neonatal intensive care units (NICUs).
  • To investigate the outcomes of repeated UVC insertion attempts after initial failure.

Main Methods:

  • A prospective, multi-center observational study.
  • Data collected from 101 UVC insertions across 4 tertiary NICUs between March 2019 and January 2020.

Main Results:

  • Seventy-two percent of UVCs achieved central placement on the first attempt, compared to 50% on subsequent attempts.
  • Failed initial attempts were associated with lower rates of central UVC placement (p=0.009).
  • Procedures with first-attempt central placement were significantly shorter (p=0.0292).

Conclusions:

  • Repetitive UVC insertion attempts and manipulations offer limited benefit for achieving central placement in neonates.
  • Multiple insertion attempts increase the overall procedure duration, impacting neonatal care efficiency.
