Insights

Peripheral intravenous catheters (PICs) in neonates have short dwell times. Using splints with PICs in neonates significantly increased catheter dwell time but may delay extravasation detection.

Area of Science:

  • Neonatal intensive care
  • Medical device efficacy
  • Clinical nursing research

Background:

  • Neonatal peripheral intravenous catheters (PICs) present challenges due to short dwell times and frequent replacement needs.
  • Interventions like splints are explored to prolong the indwelling time of PICs in neonates.
  • This study investigates complications and dwell time of PICs with and without splints in a neonatal intensive care unit.

Purpose of the Study:

  • To determine the complications associated with peripheral intravenous catheters (PICs) in neonates.
  • To compare the dwell time of PICs when used with and without splints in infants.
  • To evaluate the impact of splints on the longevity and safety of PICs in the neonatal intensive care unit.

Main Methods:

  • A descriptive, correlational, and prospective study was conducted on neonates in Mahdieh Hospital, Tehran.
  • Neonates were divided into two groups: those with splints and those without splints.
  • Catheter dwell time and complications were monitored thrice daily for three months using a researcher-made checklist and analyzed with IBM SPSS 16.

Main Results:

  • Extravasation was the most frequent complication in the splint group (52.40%), while obstruction was most common in the non-splint group (34.50%).
  • The mean dwell time for PICs was 43.29 hours with splints and 37.18 hours without splints.
  • Statistical analysis showed a significant positive impact of splints on catheter dwell time (t = 2.59, p = 0.01).

Conclusions:

  • Splints have a significant positive effect on increasing the dwell time of peripheral intravenous catheters in neonates.
  • While splints extend catheter dwell time, they may potentially delay the detection of complications like extravasation.
  • The absence of splints may increase catheter occlusion rates, leading to earlier removal.

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,...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

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...

Venous Thrombosis IV: Nursing Management

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,...

Cardiac Catheterization IV: Nursing Management

Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...

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,...

Venous Thrombosis III: Interprofessional Care

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...
