Summary
This summary is machine-generated.This study establishes local radiation dose reference levels for pediatric cardiac catheterization, finding fluoroscopy time insufficient for monitoring exposure. These levels aid in optimizing procedures and reducing radiation for children with congenital heart defects (CHDs).
Area Of Science
- Medical Physics
- Pediatric Cardiology
- Radiological Protection
Background
- Children with congenital heart defects (CHDs) undergo procedures involving ionizing radiation.
- Data on radiation doses in pediatric cardiac catheterization is limited.
- Establishing reference levels is crucial for patient safety.
Purpose Of The Study
- To investigate radiation doses and related parameters during pediatric cardiac catheterization.
- To propose local dose reference levels for these procedures.
- To provide benchmarks for optimizing radiation safety in pediatric patients.
Main Methods
- Collected radiation exposure data (fluoroscopy time, dose-area product, air kerma, absorbed dose) from January to November 2021.
- Measured absorbed dose using Bhabha Atomic Research Centre dosimeters.
- Analyzed data using Kolmogorov-Smirnov test and Spearman's correlation coefficient.
Main Results
- Median dose-area product: 300 mg·m², fluoroscopy time: 10.5 mins, air kerma: 37 mGy, absorbed dose: 2.4 mSv.
- Strong correlation found between fluoroscopy time and absorbed radiation dose (Rho = 0.942).
- Proposed local dose reference levels categorized by age groups.
Conclusions
- Fluoroscopy time alone is inadequate for monitoring radiation exposure.
- Air kerma and dose-area product levels varied significantly even with similar fluoroscopy times.
- Proposed local dose reference levels serve as benchmarks for future radiation reduction strategies.

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...
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
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...
Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...
