ABSTRACT
Objective To understand current status of occupational protection awareness and behavior among dif-ferent professional medical interns,and provide basis for strengthening the education about occupational protection among medical interns .Methods Questionnaire survey was used to survey medical interns at the end of their clini-cal internship.Results A total of 385 cases of occupational exposure occurred during internship period,occupation-al exposure rate was 42.31 % (385/910),occupational exposure mainly occurred in nursing interns (n =190).358 (39.34%)medical interns understood self-protective antibody (hepatitis B surface antibody);difference in occupa-tional exposure rates and awareness of self-protective antibody among different professional medical interns was sta-tistically significant (all P <0.05);222 (57.66%)medical interns sustained occupational exposure more than once, 45.45% of occupational exposure occurred during the process of diagnostic and therapeutic procedure,exposure mainly occurred in the wards (32.21 %).After occupational exposure,46.75% of medical interns felt nervous, 35.06% were worried,18.18% appeared serious psychological reaction,only 14.03% sought support and help from others.Conclusion Awareness of occupational protection among medical interns is insufficient,education and awareness of occupational protection should be intensified,psychological behavioral after occupational exposure should be paid attention among medical students.
ABSTRACT
ObjectiveTo explore the influence of washable type subglottic attract on incidence of ventilator-associated pneumonia (VAP) in patients with mechanical ventilation. Methods356 cases in need of mechanical ventilation from July 2009 to July 2010 in our hospital were chosen as the research object.They were randomly divided into the observation group and the control group with 178 cases in each group.The control group was treated with conventional endotracheal tube for mechanical ventilation.The observation group used washable type subglottic endotracheal tube to attract for mechanical ventilation.The VAP rate for the two groups occurred during mechanical ventilation in ventilator was compared.Migration of the dominant bacteria of the subglottic secretion was detected,underwent pathogenic examination and drug sensitivity test. ResultsThe VAP rate was significantly lower in the observation group than that of the control group.186 bacteria strains were detected from subglottic secretion,and 169 were detected from lower respiratory tract. ConclusionsWashable type subglottic attract for mechanical ventilation can reduce the risk of ventilator-associated pneumonia for patients with mechanical ventilation significantly,and it is worthy of clinical application.
