Anesthesiologists in the neurointerventional suite: what is appropriate radiation protection?

摘要

IN their article on radiation exposure of anesthesiologists, Anastasian et al.l recommend that anesthesiologists follow the practice of radiologists and wear leaded glasses to prevent cataracts when monitoring patients during neuroint-erventional cases. This recommendation was based on radiation exposure to the anesthesiologist detected by a dosimeter placed on the forehead; the dosimeter measured, on average, more than three times the exposure of the radiologist, the differential being because of the configuration of die horizontal fluoroscopy beam that subjected the anesthesiologist to more scatter radiation. The study found the exposure to the anesthesiologist to be small, averaging only 6.5 ju,Sv per procedure. This low figure is likely because of placement of a leaded glass shield between the anesthesiologist and the fluoroscopy apparatus.
