ABSTRACT
Objective:To investigate the clinical significance of grip strength, three simple lung functions[functional volume capacity(FVC), forced expiratory volume in the first second(FEV1)and peak expiratory flow(PEF)], 6-minute walking distance test(6MWD)and left ventricular ejection fraction(LVEF)for assessing overall integrative function in elderly versus non-elderly patients with coronary artery disease(CAD).Methods:A total of 35 hospitalized CAD patients aged 70.4±10.6 years from January 2017 to December 2018 were retrospectively enrolled.Patients were divided into the non-elderly group(<65 years, n=8)and the elderly group(≥65 years, n=27). FVC, FEV1 and PEF were tested by a portable lung function machine.The grip strength, 6MWD, three simple lung functions(FVC, FEV1, PEF), LVEF and echocardiography were detected after admission.The above indexes were re-examined in outpatient clinic at 3 months after discharge.The results of above indexes were compared at admission versus at three months after discharge.The consistency and correlation between FVC, FEV1, PEF, 6MWD, grip strength and LVEF were analyzed.Results:The detected results of FVC, FEV1, PEF, 6MWD, left-hand grip strength, right-hand grip strength and LVEF showed no significant difference at admission versus at 3 months after discharge( P>0.05)in a total of 35 hospitalized CAD patients.Pearson bivariate correlation analysis showed that FVC, FEV1, PEF, left-hand and right-hand grip strength had pairwise correlation between them( P<0.01).6MWD had no correlation with LVEF.And LVEF was related with FVC and FEV( P<0.01), but not related with PEF, 6MWD and grip strength( P>0.05). The detective values of FVC, FEV1, PEF, 6MWD, left-hand and right-hand grip strength were lower in the elderly group than in the non-elderly group[(2.11±0.66 )L vs.(2.88±0.55) L, (1.74±0.46 )L vs.(2.62±0.49 )L, (5.50±1.79 )m/s vs.(8.22±1.59) m/s, (332.07±115.58)m vs.(446.14±99.81 )m, (25.14±7.87) vs.(35.15±8.30), (27.37±8.39 )kg vs.(38.37±10.20)kg, P<0.01]. LVEF had no significant difference between the two age groups. Conclusions:FVC, FEV1, PEF, 6MWD and grip strength are lower in elderly group than in non-elderly group.A comprehensive set of tests of grip strength, three simple lung function and 6MWT is helpful to evaluate the overall integrative function in elderly CHD patients.
ABSTRACT
Objective:To explore and analyze the correlation between nurses' willingness to stay in the operating room and job stressor, job burnout and work-family conflict.Methods:A total of 128 nurses from Mianyang Central Hospital, Third People′s Hospital of Mianyang, Mianyang People′s Hospital were selected as the research objects. The questionnaire of nurses' retention intention, the scale of nurses' job stressor, the scale of nurses' occupational fatigue and the scale of work stress conflict were used to investigate and analyze the correlation between nurses' retention intention and work stressor, occupational fatigue and family conflict.Results:The average retention intention of the nurses surveyed in this study was (3.16±0.71), and the retention intention of the nurses was in the middle level. Operating room nurses' total score of work stress was (95.27±15.28). Among them, the scores of time allocation and workload, nursing specialty and work were the highest (2.86 ± 0.73) and (2.75 ± 0.64), respectively. The highest score of personal achievement was (33.26 ± 8.39). The total score of work family conflict of nurses in operating room was (58.32 ± 11.29), and the total score was (3.09 ± 0.58). The average score of work family conflict based on time was the highest, which was (3.91 ± 0.64), which was the main source of work family conflict of nurses. Pearson correlation analysis showed that nurses' intention to stay was negatively correlated with work pressure, job burnout and work family conflict ( r value was-0.374,-0.400,-0.327, P < 0.05). Conclusions:Nurses' willingness to stay in the operating room is at a medium level. Nursing managers can reduce the pressure of occupational fatigue by reducing work stress and improve the willingness of nursing staff to stay.
