Clinical studyEstimates of Effective Dose to Pediatric Patients Undergoing Enteric and Venous Access Procedures
Section snippets
Study Overview
This study was approved by the hospital institutional review board and complied with all institutional review board guidelines for patient data access and storage.
A retrospective review was conducted of enteric and venous access procedures performed at our institution. Cases were identified through a dedicated interventional radiology database that has records on patient demographics, procedure performed, equipment use, costs, personnel, and fluoroscopy time since 1993. For this study, 7,074
Results
The number of cases for each of the nine procedures performed in the time period from 2004 to 2008 are given in Table 1. In total, 3,405 enteric and 3,669 venous access cases had effective dose estimates retrospectively estimated.
Table 2 outlines the standardized magnification and geometry parameters applied to each of the nine simulation examinations. The measured entrance exposure recorded with the digital dose meter is also given and represents the proportioned exposure associated with 1
Discussion
Fluoroscopically guided enteric and venous access procedures represent a significant portion of IR practice in adults and children, accounting for 63% of procedures in our center and 66% of IR cases involving ionizing radiation. Rarely do enteric and venous access cases result in radiation doses that approach or exceed the 2-Gy threshold for deterministic skin effects (16, 17), even if multiple procedures are performed within a relatively short period of time (18, 19). In children, peak skin

In-hospital resource utilization, outcome analysis and radiation exposure in children undergoing appendicostomy vs cecostomy tube placement
2020, Journal of Pediatric UrologyCitation Excerpt :Overall, this would indicate that the collective burden is lower for the appendicostomy cohort. That said, all REE in this work applied a relatively low dose of radiation compared to other radiological modalities and only that which was necessary to satisfy the intervention and diagnostic task, which is in keeping with other series interrogating the effective dose of radiation in children undergoing enteric access procedures, and raises the argument that the differences in radiation exposure between the groups is of unclear clinical significance [16]. Furthermore, as technology improves the cumulative dose may become even lower.
