Insights

Peripherally inserted central catheter (PICC) lines improve nutrient delivery for moderately preterm infants. This leads to significantly better weight gain by discharge, supporting enhanced growth in this vulnerable population.

Area of Science:

  • Neonatal Nutrition
  • Pediatric Gastroenterology
  • Infant Growth and Development

Background:

  • Nutritional support practices vary for moderately preterm infants (32-34 weeks gestation).
  • Very preterm infants (<32 weeks gestation) routinely receive intensive nutritional support via central lines.

Purpose of the Study:

  • To evaluate the impact of peripherally inserted central catheter (PICC) use on nutrient delivery within the first two weeks of life.
  • To assess the effect of PICC-delivered nutrition on growth outcomes in moderately preterm infants by hospital discharge.

Main Methods:

  • Retrospective analysis of 187 infants born between 32 and 34 6/7 weeks gestation.
  • Comparison of nutrient intake and weight gain between infants receiving nutrition via PICC and those who did not.
  • Data collection included feedings, weights, and PICC placement records.

Main Results:

  • Infants receiving nutrition via PICC had significantly higher kilocalorie and protein intake in the first week of life.
  • PICC group infants received an average of 17.6 more kcal/day and 1.2 more g protein/kg/day.
  • By discharge, infants in the PICC group showed significantly greater weight gain (302g more).

Conclusions:

  • Peripherally inserted central catheter (PICC) lines facilitate superior nutrient delivery in moderately preterm infants.
  • PICC use is associated with enhanced growth and weight gain in this population.
  • This method supports improved nutritional outcomes for infants born between 32-34 weeks gestation.

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,...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Enteral Nutrition I: Orogastric and Nasogastric Feeding

Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

Peritoneal dialysis, or PD, utilizes the peritoneal membrane as a filter to eliminate excess fluid and waste products. Effective nursing management is essential for ensuring patient safety, preventing complications, and promoting optimal function of the peritoneal dialysis process.Assessment and MonitoringNurses must thoroughly assess the patient before, during, and after each dialysis session. Regular monitoring includes vital signs, daily weight, fluid intake and output, and laboratory values...
