Insights

This study analyzed radiation exposure in pediatric patients undergoing multiple cardiac interventional procedures. Higher procedure counts correlated with increased cumulative radiation doses and organ exposure, highlighting the need for radiation safety in pediatric cardiology.

Area of Science:

  • Medical Physics
  • Pediatric Cardiology
  • Radiology

Background:

  • Interventional cardiac procedures are increasingly common in pediatric patients.
  • Assessing radiation exposure is crucial for patient safety and epidemiological studies.
  • Limited data exists on cumulative radiation doses for children undergoing multiple cardiac interventions.

Purpose of the Study:

  • To determine the frequency of multiple interventional cardiac procedures in pediatric patients.
  • To analyze cumulative radiation doses (KAP, CAK, organ doses, effective dose) for patients undergoing 2, 3, or ≥4 procedures.
  • To provide data for radiation safety optimization in pediatric interventional cardiology.

Main Methods:

  • Retrospective analysis of 1521 pediatric patients and 1824 procedures over 9 years.
  • Measurement of cumulative Kerma Area Product (KAP) and cumulative air kerma (CAK).
  • Monte Carlo software used for calculating organ doses and effective doses.

Main Results:

  • 13.7% of patients had 2 procedures, 4.1% had 3, and 1.4% had ≥4.
  • Median KAP increased with procedures: 3.7 Gy·cm² (2), 5.4 Gy·cm² (3), 10.8 Gy·cm² (≥4).
  • Effective doses ranged from 3.4 mSv (2 procedures) to 8.7 mSv (≥4 procedures), with significant organ doses observed.

Conclusions:

  • A notable percentage of pediatric patients undergo multiple cardiac interventional procedures.
  • Cumulative radiation doses significantly increase with the number of procedures.
  • Findings emphasize the importance of radiation dose monitoring and management in pediatric interventional cardiology.

Determination of Multiple Dosing Parameters: Loading and Maintenance Doses

A loading dose is an essential pharmacological strategy to rapidly achieve the target plasma drug concentration necessary for an immediate therapeutic effect. This approach is especially critical for drugs characterized by slow absorption or extended half-lives, where delaying therapeutic plasma levels could compromise treatment outcomes. By administering a loading dose, clinicians ensure a prompt onset of drug action, even for agents with complex pharmacokinetic profiles.Achieving steady-state...

Drug Dosing: Geriatric Patients

Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Drug Dosing: Obese Patients

In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Insulin: Dosing Regimen and Adverse Effects

Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

Bioavailability Study Design: Single Versus Multiple Dose Studies

Bioavailability studies are essential for understanding how a drug is absorbed, distributed, metabolized, and excreted in the body. These studies assess the extent and rate at which the active pharmaceutical agent becomes available at the site of action. The design of bioavailability studies can involve single-dose or multiple-dose regimens, each with distinct advantages and limitations.Single-dose studies are the preferred approach due to their simplicity and reduced drug exposure for...

Drug Accumulation During Multiple Dosing: Repetitive IV Injections

Calculating drug dosage and accumulation in multiple-dose regimens is crucial for achieving therapeutic efficacy while avoiding toxicity. This involves determining the plasma drug concentrations over time to optimize dosing schedules. The principle of superposition is fundamental in this process, allowing for the prediction of drug concentration in plasma following multiple doses based on single-dose data.The principle of superposition asserts that the plasma concentration-time curves from...
