Evaluation of biochemical parameters in operating room staff exposed to radiation and anesthetic gases

Abstract

Background: Exposure to ionizing radiations and other hazardous agents such as anesthetic gases pose serious risks to the health of healthcare workers. This study aimed to evaluate the changes in blood and biochemical parameters of the operating room staff exposed to ionizing radiations and remnants of anesthetic gas. Methods: This cross-sectional study was performed at (XXX). The control group was selected from different parts of the hospital that were not exposed to ionizing radiations and anesthetics, including office, services, and treatment. The case group included all operating room personnel. Hematopoietic parameters such as complete blood count and WBC differential, parameters of liver function such as serum activity of liver enzymes (ALT, AST, ALP, LDH) and serum bilirubin levels, fasting blood sugar, serum lipid profile, level of vitamin D and magnesium were measured for the exposed and referent subjects. Additionally, a checklist was used to gather data regarding the occupational variables and medical histories of the studied subjects. Results: The mean values of Hb, Hct, Vitamin D, and MCHC, as well as the RBC count, were significantly lower in the exposed individuals than in the referent subjects. In contrast, the proportion of smokers was significantly higher in the exposed group than in the referent group. No significant differences were noted between exposed and unexposed groups as far as other parameters were concerned. However, no significant differences were noted between case and control groups as far as other measured parameters were concerned. Likewise, no significant differences were noted between exposed and referent groups as far as blood types, history of underlying diseases, work history, working hours per month, number of morning and evening shift hours, type of diet, consumption of high-fat diet a day before blood sampling, x-ray in the recent year, history of radiotherapy and therapeutic agents use was concerned. Conclusions: Exposure of operating room staff to ionizing radiations and waste anesthetics gases is associated with subtle, sub-clinical pre-pathologic decreases in some hematopoietic parameters such as hemoglobin, hematocrit and MCHC levels, RBC count as well as Vitamin D levels.
