ABSTRACT
Objective:To summarize the nursing experience in 2 patients with cardiogenic shock combined with acute respiratory distress syndrome(ARDS) treated by extracorporeal membrane oxygenation (ECMO) and transferred outer-hospital in long distance.Methods:There were many risk factors in this transport: high parameters of ECMO included V-A mode, 100% oxygen, and a flow of oxygen from 6 L/min to 10 L/min. High ventilator parameters included oxygen concentration of 100% and positive end-expiratory pressure of 15-17 cmH 2O(1 cmH 2O=0.098 kPa). Transport distance was up to 196 km. And the transport time was up to 2 h 36 min. In this regard, we carried out adequate preparations before transport and professional cares during transport. The main points were as follows: setted up a professional transport team; prepared adequate power and oxygen supply; reduced the number of interruption of ECMO and ventilator support during transport; provided the reasonable remedial actions when ECMO and ventilator support were interrupted. Results:Two patients arrived at the destination safely.Conclusions:Adequate preparations before transport and professional cares during transport could effectively avoid and respond to the occurrence of adverse events, and it is feasible and safe to patients supported by ECMO for long distance outer-hospital transport.
ABSTRACT
Objective@#To investigate the effect of leader-member exchange on nurses’sense of calling in workplace based on self-determination theory.@*Methods@#A total of 381 nurses were randomly selected from five tertiary general hospitals in Zhejiang province, China from October to December, 2016. They were subjected to a survey using the Leader-Member Exchange Scale, Job Autonomy Scale, Core Self-Evaluation Scale, and Calling Scale. The mediating effect was used to test the procedures and the data were subjected to hierarchical regression analysis.@*Results@#The leader-member exchange was positively correlated with job autonomy, core self-evaluation, and sense of calling (r=0.471, P<0.001; r=0.373, P<0.001; r=0.475, P<0.001) ; the leader-member exchange had a positive predictive effect on job autonomy and sense of calling (β= 0.47, P<0.001; β=0.48, P<0.001) ; the job autonomy had a partial mediating effect on the relationship between leader-member exchange and sense of calling (F=66.50, P<0.001) ; the core self-evaluation negatively adjusted the positive relationship between leader-member exchange and job autonomy (F=27.81, P<0.001) .@*Conclusion@#High-quality leader-member exchange enhances the sense of calling by improving staffs’ job autonomy and the core self-evaluation reduces the positive relationship between leader-member exchange and job autonomy.
ABSTRACT
Objective@#To investigate the effect of occupational exposure on job burnout in nurses, and to analyze the mediating effect of negative emotion between occupational exposure and job burnout and the regulatory effect of supervisor support on occupational exposure and negative emotion.@*Methods@#From September to December, 2015, simple random sampling was used to select 543 nurses from six tertiary hospitals in Zhejiang Province, China. The questionnaires consisted of occupational exposure risk questionnaire, negative emotion questionnaire, supervisor support questionnaire, and job burnout questionnaire.@*Results@#The total score of occupational exposure risk in nurses was 11.43±7.19; the score of emotional exhaustion was 3.19±1.24, the score of low sense of personal accomplishment was 3.02±1.21, and the score of sense of working indifference was 2.24±1.06. There were significant differences in occupational exposure score between nurses with different sexes (t=2.61, P<0.01) and working years (F=4.49, P<0.01) . There were significant differences in the scores of emotional exhaustion and low sense of personal accomplishment in nurses with different sexes (t=5.25, P<0.001) and working years (t=-3.48, P<0.01) . Occupational exposure had positive effects on negative emotion (β=0.41, P<0.05) , emotional exhaustion (β=0.47, P<0.05) , sense of working indifference (β=0.42, P<0.05) , and low sense of personal accomplishment (β=0.17, P<0.05) . Negative emotion had a partial mediating effect between occupational exposure and emotional exhaustion (total effect size 30.5%, P<0.05) and between occupational exposure and sense of working indifference (total effect size 37.1%, P<0.05) . Negative emotion had a complete mediating effect between occupational exposure and low sense of personal accomplishment (β=0.08, P>0.05) . Supervisor support negatively regulate the effects of occupational exposure and negative emotion (F=21.73, P<0.001) .@*Conclusion@#In nurses, occupational exposure has a direct positive effect on job burnout and indirectly influences job burnout via negative emotion. Supervisor support can reduce the negative impact of occupational exposure on negative emotion.
