Abstract

Background: Operating room personnel are subject to occupational hazards which could lead to an increase in free radicals and develop various diseases. The aim of the present study was to determine the effect of consuming green tea on the improvement of the blood oxidative biomarkers in operating room personnel who are exposed to anesthetic gases.

Materials and Methods: This study was a before-after clinical trial which was conducted on 24 operating room personnel. They were invited to consume 4 cups of a green tea beverage, prepared from 3 g of green tea leaves in 300 mL of boiled water (at 80˚ C), daily for 8 weeks. Then, Myeloperoxidase (MPO), DNA damage, Glutathione Peroxidase (GPx), and Superoxide Dismutase (SOD) in the plasma were measured in order to evaluate the level of oxidative stress biomarkers before and after consuming green tea.

Results: Green tea consumption by operating room personnel brought about a significant increase in glutathione peroxidase and superoxide dismutase and a considerable decrease in myeloperoxidase and DNA damage.

Conclusion: According to the results of this study, green tea consumption as an antioxidant supplement by operating room personnel, who are regularly exposed to anesthetic gases, can minimize oxidative stress and DNA damage considerably. Thus, it is advisable for operating room personnel to consume green tea as a natural antioxidant supplement.

Abstract

Introduction: The period of the epidemic of covid-19 is a critical situation where the operating room personnel are in the front line and are in more contact with the sick patient and his respiratory tract. The purpose of this study is to determine the preventive behaviors of operating room personnel of Isfahan teaching hospitals during the epidemic of Covid-19.
Methods: In this cross-sectional descriptive study, 100 operating room personnel of Isfahan teaching hospitals were investigated in 2019-1400. The required information was collected with the help of demographic information questionnaires and a standard questionnaire of specific questions related to preventive behaviors. Data collection was done from March 1999 to June 1400, then it was analyzed by SPSS statistical software. The Research Ethics Committee of Sari University of Medical Sciences has registered this study with the code IR.MAZUMS.REC.1400.115.
Results: The average rate of compliance with preventive behaviors among operating room personnel was 64.53%, which was above the average level. The highest compliance rate was preventive behaviors after the patient with corona virus left the operating room (84.50%). In this research, 100 health care personnel of operating rooms participated in the study. The gender of the majority of them (74%) was female and 63% of them were under 30 years of age. The participants stated that after the patient with corona virus leaves the operating room, they often or always dispose of the patient's consumables correctly (85%), complete disinfection. It was done with detergents (87%), using UV rays (86%), storing and transporting samples in special double-layered containers and fully complying with hygiene principles (83%).
Conclusions: The results showed that at the time of admission of the patient without Covid 19, contraceptive protocols were observed to a lesser extent than when the patient with Covid was admitted. Preventive behaviors and staff knowledge and awareness about the proper use of personal protective equipment can play an effective role in reducing their incidence.
