Insights

Pediatric patients with single ventricle (SV) physiology often experience malnutrition after the bidirectional Glenn (BDG) procedure. Optimal nutritional status is crucial for improving surgical outcomes and recovery in these children.

Area of Science:

  • Pediatric Cardiology
  • Pediatric Surgery
  • Nutritional Science

Background:

  • Single ventricle (SV) physiology presents significant challenges in pediatric patients, often leading to growth retardation.
  • Nutritional status is a critical determinant for successful surgical staging in children with SV, particularly after the bidirectional Glenn (BDG) procedure.

Purpose of the Study:

  • To evaluate the nutritional status of pediatric patients with SV following the BDG procedure.
  • To identify anthropometric parameters linked to short-term surgical outcomes in this patient cohort.

Main Methods:

  • Inclusion of 151 pediatric patients who underwent the BDG procedure.
  • Assessment of nutritional status using anthropometric measurements and the Infant and Child Feeding Index (ICFI).
  • Correlation analysis between nutritional indicators (ICFI, HAZ, WAZ) and clinical outcomes (ventilation time, infection, ICU stay).

Main Results:

  • A significant correlation was observed between ICFI scores and malnutrition, as indicated by height-for-age Z-score (HAZ) and weight-for-age Z-score (WAZ) (P < 0.05).
  • Clinical outcomes, including ventilation time, nosocomial infection, pressure injury, peritoneal dialysis, and ICU days, showed significant differences among HAZ groups (P < 0.05).
  • Nosocomial infection rates differed significantly among WAZ groups (P < 0.05), highlighting the impact of nutritional status on post-operative complications.

Conclusions:

  • Children with SV undergoing the BDG procedure exhibit a high prevalence of malnutrition.
  • Dietary intake patterns, alongside disease-specific factors, significantly influence clinical outcomes during hospitalization.
  • Maintaining optimal nutritional status is essential for improving surgical feasibility and patient recovery in infants with SV undergoing staged surgical interventions.

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.

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 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,...

Cardiomyopathy VII: Pre and Post Operative Nursing Management

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...
