RESUMEN
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 (Ayatollah Taleghani Hospital). The control group was selected from different parts of the hospital that were not exposed to ionizing radiations and anesthetics, including the office, services, and treatment. The case group included all operating room personnel. Hematopoietic parameters such as complete blood count and WBC differential, and 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 the 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 a 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, subclinical prepathologic decreases in some hematopoietic parameters such as hemoglobin, hematocrit and MCHC levels, RBC count as well as vitamin D levels.
RESUMEN
BACKGROUND: The aim of this study was to explore the effect of occupational exposure to X-ray on hematological parameters. RESEARCH DESIGN AND METHODS: A systematic search was conducted in the Scopus, PubMed, Web of Science, and Embase databases up to April 2020. The methodological quality was assessed by Joanna Briggs Institute (JBI) Critical Appraisal Checklist . The random-effects model was used to estimate the effect size (standard difference in means (SDMs)). RESULTS: Out of 1750 identified citations, ten studies met the inclusion criteria The overall effect size did not show any significant difference between the two groups (SMDs ranged from -0.382 ± 0.29 for white blood cells (WBC), 0.213 ± 0.40 for platelet, -0.323 ± 0.0.16 for mean corpuscular volume (MCV), 0.553 ± 0.41 for mean corpuscular hemoglobin concentration (MCHC), -1.615 ± 1.41 for monocyte, 0.418 ± 0.49 for lymphocyte (P-value>0.05). Only the effect size of red blood cells was significantly higher than that of the control group (SMD = 1.06 ± 0.28; 95% CI: 0.504, 1.615; P-value = 0.001). CONCLUSION: The long-term and low-dose radiation may have no significant effect on blood parameters. Future studies are suggested to use other tests such as dicentric chromosome assay (DCA), cytogenetic tests, and modern tests besides blood count parameters.
