Objective To investigate the status quo and influencing factors of compassion fatigue among nurses in psychiatric hospitals. Methods The self-designed demographic questionnaire,compassion fatigue scale,occupation-al identity assessment scale and social support rating scale were employed to investigate 480 nurses in five psychi-atric hospitals from two provinces. Results The scores for each dimension in compassion fatigue scale were as fol-lows:compassion satisfaction(32.26±5.34),occupational burnout(27.67±4.34),and secondary traumatic stress(23.72± 4.41).Age,position,individual monthly income,health status,job satisfaction and occupational identity had significant influence on compassion satisfaction(F=19.351,P<0.001). Individual monthly income,health status,job satisfaction and occupational identity had significant influence on occupation burnout (F=35.705,P<0.001). Individual monthly income, personality and social support had significant influence on secondary traumatic stress(F=17.203,P<0.001). Conclusion Nurses in psychiatric hospitals had severe compassion fatigue and this status was influenced by multiple reasons. Nursing managers should pay great attention to nurses with low monthly income,poor health,low job satisfaction, weak social support and low occupational identity,and take effective measures to decrease compassion fatigue of nurses.

Objective To explore the clinical value of transnasal high volume oxygen therapy in the treatment of patients with acute heart failure.Methods From January 2016 to January 2018,61 cases with acute heart failure in Huxi Hospital Affiliated to Jining Medical College were selected.The patients were randomly divided into control group and treatment group according to the digital table,31 cases in the control group and 30 cases in the treatment group.The two groups were routinely given control of fluid volume,analgesia,strong heart,diuresis,vasodilator,anti-platelet aggregation,camp support and so on.The control group was given conventional oxygen therapy,and the treatment group was treated with high flow oxygen through nose.Before treatment and 12h,24h,48h,72h after treatment,the left ventricular ejection fraction (LVEF),oxygen index (PaO2/FiO2),serum lactic acid (Lac),B type sodium and titanium (BNP) in serum,and the application rate of non-invasive mechanical ventilation and invasive mechanical ventilation in 7d were observed in the two groups.Results Compared with the control group,the LVEF of the treatment group in each time point increased [(35.58 ± 3.64) ％ vs.(37.77 ± 3.76) ％,(37.87 ± 3.58) ％ vs.(40.07 ±3.36)％,(44.94 ±3.19)％ vs.(46.83 ±3.21)％,(47.55 ±3.45％)％ vs.(40.07 ±3.36％)％,t =-2.308,-2.466,-2.316,-2.487,all P ＜ 0.05].The PaO2/FiO2 of the treatment group increased significantly at each time point after treatment [(177.39 ± 10.62) mmHg vs.(184.17 ± 10.49) mmHg,(188.00 ± 11.72) mmHg vs.(198.57 ± 18.47) mmHg,(204.06 ± 17.69) mmHg vs.(221.40 ± 23.80) mmHg,(265.23 ± 34.51) mmHg vs.(290.37 ± 26.72) mmHg,t =-2.507,-2.678,-3.236,-3.174,all P ＜ 0.05].The BNP level of the treatment group decreased significantly at each time point after treatment [(2 462.90 ± 288.00) ng/mL vs.(2 264.53 ± 366.44) ng/mL,(1 646.61 ± 377.19) ng/mL vs.(1 474.07 ± 214.03) ng/mL,(991.94 ± 242.95) ng/mL vs.(811.90 ±258.67) ng/mL,(653.77 ± 147.671) ng/mL vs.(526.47 ± 127.87) ng/mL,t =2.355,2.187,2.803,3.594,all P ＜ 0.05].The Lac level of the treatment group decreased significantly at 12h and 24h after treatment [(5.05 ± 0.69) mmol/L vs.(4.55 ± 0.80) mmol/L,(3.68 ± 0.89) mmol/L vs.(3.13 ± 0.77) mmol/L,t =2.610,2.601,all P ＜ 0.05],but there were no statistically significant differences between the two groups at 48h and 72h after treatment [(1.62 ± 0.65) mmol/L vs.(1.53 ± 0.65) mmol/L,(1.36 ± 0.64) mmol/L vs.(1.26 ± 0.46) mmol/L,all P ＞ 0.05].In the control group and the treatment group,the incidence rates of non-invasive mechanical ventilation in 7d were 35.48％ (11/31),13.33％ (4/30),respetively,the difference was statistically significant (x2 =4.034,P ＜ 0.05).In the control group and the treatment group,the incidence rates of invasive mechanical ventilation in 7d were 12.90％ (4/31),3.33％ (1/30),respetively,the difference was statistically significant (x2 =4.957,P ＜ 0.05).Conclusion Nasal high flow oxygen therapy has better clinical effect on patients with acute heart failure.It is a more active treatment measure,and is worthy of clinical application.
