Fluoroscopic Pulse Rate for Radiation Exposure
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine if reducing the number of X-ray pulses during a heart procedure can lower radiation exposure for doctors. It compares two pulse rates: an ultra-low dose fluoroscopic pulse rate of 3.75 pulses per second and a standard low dose fluoroscopic pulse rate of 7.5 pulses per second. The focus is on operators using a right radial artery approach, where the procedure is performed through an artery in the wrist. This trial is suitable for patients undergoing a coronary angiogram through the right radial artery. As an unphased study, it offers patients the opportunity to contribute to research that could enhance safety in heart procedures.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications.
What prior data suggests that this method is safe for reducing radiation exposure?
Research has shown that using a very low rate of X-ray images, such as 3.75 images per second, significantly reduces radiation exposure for doctors during procedures. Typically, up to 15 images per second are used, so lowering this rate represents a substantial change. Studies indicate that even reducing the rate to 7.5 images per second decreases radiation without causing any issues.
This suggests that using a very low rate is safe and well-tolerated. No evidence of harmful effects exists for doctors using these lower rates, which is encouraging for those considering joining trials aimed at reducing radiation.12345Why are researchers excited about this trial?
Researchers are excited about this trial because it explores how reducing the fluoroscopic pulse rate during coronary angiography might decrease radiation exposure for operators. Unlike the standard rate of 7.5 pulses per second, the ultra-low dose approach uses only 3.75 pulses per second, potentially cutting radiation exposure in half. This could lead to safer working conditions for healthcare professionals without sacrificing the quality of diagnostic imaging.
What evidence suggests that this trial's fluoroscopic pulse rates could be effective in reducing radiation exposure?
This trial will compare two fluoroscopic pulse rates to assess radiation exposure during heart procedures. Research has shown that using a lower rate of X-ray pulses can reduce radiation exposure for doctors. Participants in this trial will receive either a standard low dose of 7.5 frames per second (FPS) or an ultra-low dose of 3.75 FPS. Studies indicate that the standard low rate already decreases radiation compared to higher rates. Early results suggest that the ultra-low rate might reduce radiation further. This reduction is important because less radiation can lead to better long-term health for both patients and doctors. Lowering the pulse rate is a simple change that can greatly improve safety.14678
