| Objective:According to Green's model,the current status of knowledge,attitude and practice and protection education of nurses in operating room were assessed.Aiming at the problems and links that affect the implementation of protective behavior of nurses in operating room,intervention education and effect evaluation were carried out.To improve the mastery rate and protection compliance of nurses in operating room,reduce the harm of electrical surgical smoke to human body,ensure the physical and mental health of nurses in operating room,and provide basis for smoke protection education.Methods:There are three parts in this study.The first part is to design the questionnaire.With the keyword of "surgical smoke",we searched the literature at home and abroad and summarized it.We evaluated the characteristics of the operating room nurses' behavior environment,epidemiology,sociology,management policy and educational organization,and designed the preliminary draft of the questionnaire.Then we conducted a preliminary survey of 30 operating room nurses through five expert inquiries,and completed the questionnaire design.The second part is descriptive research.240 nurses in operation room were randomly selected to investigate their general characteristics,smoke protection knowledge-letter-practice status and protection education status.Among them,the survey included the age(age),working years/years,professional titles,number of smokeprevention training,smoke knowledge,attitude and scores of smoke-affected self-assessment of operating room nurses.The third part is the intervention study.The research method is similar to the experimental research method.54 operating room nurses in a third-class A hospital in our province were trained.The scores of knowledge,belief and behavior of operating room nurses before and after intervention were counted.The scores of self-assessment and the frequency of adverse reactions caused by smoke were also counted.The data were processed by SPSS23.0 software,and t-test,2-test and repeated measurement analysis of variance were used to compare the effects before and after intervention.Results:1.Baseline survey results(1)The knowledge part of nurses in operating room had the lowest score of 2 and the highest score of 18,with an average of(8.70±3.31)and a qualified rate of 20.4%.The scores of physical,chemical and authority protection standards were lower(2.42±1.18),(0.98 ± 0.61)and(1.39 ± 0.96)respectively.The average score of attitude to protect surgical smoke department was(62.87±6.95),the average score of behavior to protect smoke was(42.41±7.46),and the self-rating score of nurses in operating room affected by smoke was(5.29±1.88).(2)9.1% of nurses had never participated in training about protecting surgical smoke;16.7% had participated in once protection training;59.2% had participated in twice training;only 15% had participated in three or more training.Fortunately,96.3% of nurses expressed willingness to participate in smoke protection training,while 3.7% did not think it necessary to participate in such training.2.Implementation and effect of intervention(1)After one month of intervention,the knowledge of smoke protection of nurses in operating room was significantly improved(P<0.05);the scores of related concepts,physical properties,chemical properties and authoritative protection standards weresignificantly improved(P<0.05),while the scores of smoke hazards were not significantly improved(P>0.05);the attitude of smoke protection was significantly enhanced,with statistical significance(P<0.05);Compliance increased significantly(P<0.05).After one month of intervention,the scores of self-assessment affected by smoke were significantly reduced(P<0.05).(2)Data were analyzed by repeated measures of variance.Before intervention,one month and three months after intervention,the knowledge,attitude and behavior scores of nurses in operating room for the protection of electrical surgical smoke increased gradually(F=65.570,P<0.001;F=78.307,P<0.001;F=403.015,P<0.001).Conclusion:1.Operating room nurses lack theoretical knowledge of smoke,and the items with lower scores are mainly the physical properties,chemical properties and authoritative protection standards of smoke;the attitude of smoke protection is at a medium level,mainly in two aspects: neglecting the hazards of smoke and lack of protection consciousness;and the behavior of smoke protection is poorly executed,which is manifested by inadequate personal protection measures and intraoperative smoke.The fog was not handled in time.2.Under the guidance of Green's model,the intervention education for nurses in operating room has effectively improved the theoretical knowledge and attitude level of nurses in operating room,standardized their safe and protective operation,reduced the incidence of adverse reactions and self-assessment scores affected by smoke,improved the safety level of operating room,and effectively guaranteed the health of nurses.3.The hazards and protective problems of smoke in electrical surgical department have been paid more and more attention by medical staff.Strengthening the implementation of smoke protection measures,reducing the hazards of smoke to human body and ensuring the health level of nurses in operating room are the keys to nursing work in operating room. |
