Cardiac Catheterization IV: Nursing Management

835
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...

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

1.1K
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,...

Area of Science:

  • Biomedical Engineering
  • Medical Robotics
  • Vascular Access

Background:

  • Peripheral intravenous catheterization is crucial but has a high failure rate, particularly in infants due to small veins.
  • Accidental vessel puncture is a common complication during needle insertion in pediatric patients.

Purpose of the Study:

  • To design, develop, and evaluate a novel hand-held robotic device to improve peripheral intravenous catheterization success rates.
  • To facilitate precise needle insertion and reduce complications in difficult patient populations.

Main Methods:

  • Development of a compact, low-cost hand-held robotic system for catheterization assistance.
  • Integration of an electrical impedance sensor at the needle tip for real-time venipuncture detection and process control.

Main Results:

  • The robotic device demonstrated reliable detection of venipuncture and precise needle positioning within the vein lumen.
  • Naïve users achieved an 88% success rate with the robotic device versus 12% without assistance on a phantom vessel.

Conclusions:

  • The developed hand-held robotic device is feasible for assisting intravenous catheterization.
  • This technology has the potential to significantly enhance success rates and simplify difficult catheterization procedures.
