Background: Catheter hemodialysis is the last choice for end stage kidney disease patients. Unfortunately, long-term catheterization can lead to problems that make re-catheterization challenging. Sometimes the physician has to try catheterization through several veins and stays close to the patient during the procedure that may lead to a high radiation dose exposure to the radiologist, so that some radiologists refuse to admit such patients. Objectives: The objective of this study was an assessment of the radiation dose of radiologists and patients during the placement of double lumen catheter in difficult cases.
Patients and Methods:The thermoluminescent dosimeter (TLD) was used to measure the delivered radiation dose to physicians. During the procedure, a package of dosimeter was placed on the thyroid shield and another on the chest, under the apron in order to calculate the occupational effective dose. Moreover, patient information and parameters of the procedure were recorded in order to estimate the patient dose during the procedure. Results: The mean effective dose provided by TLDs, dose/procedure, and the annual dose of physicians resulted from this procedure
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
