Determinación de dosis en la superficie de entrada recibida por pacientes sometidos a procedimientos intervencionistas en la Unidad de Hemodinámica del Hospital Carlos Andrade Marín.

Abstract

This present investigation objective is to estimate the Entrance Surface Dose received by patients who have had interventional procedures as coronary angiography, Catheterization, and Percutaneous Coronary Intervention at Carlos Andrade Marín Hospital in Quito from September 2017 to January 2018. We used thermoluminescence dosimeters provided and analyzed by the Dosimetry Department. They were located on the posterior chest cavity region inside of the radiation field. The patients selected for this investigation were classified according to medical criteria and their physical characteristics such as: height and weight. The results show that the entrance surface dose appreciation values do not exceed the limit values recommended by The International Atomic Energy Agency (IAEA) for the deterministic effect appearance in skin (less 2Gy). These appreciation values Entrance Surface Dose must be considered and analyzed by the Office of Radiation Protection of this Hospital as reference levels for the Hemodynamics unit.
