[An analysis of the current state of nurses' career satisfaction and its relationship to career calling in the tertiary hospitals].

Objective: To know about the current state of nurses' career satisfaction in the tertiary hospital, and explore the relationship between career calling and career satisfaction. Methods: From September 2017 to December, using convenience sampling, 483 nurses distributed eight tertiary hospitals were selected to complete career satisfaction scale and career calling scale. Results: The total score of nurses' career satisfaction was (2.81+0.65) , four factors were rowed from low to high in order: financial success, power and status, employability, knowledge and skill development (2.29±0.98, 2.64±0.87, 3.10±0.69, 3.20±0.71) . There were significant differences existed in different genders, marital status, educational backgrounds, working lives and positional titles (t=2.51, -1.96, -3.59; F=7.92, 8.83, P<0.05) . The score of nurses' career calling was (3.21±0.81) . There were significant differences existed in different genders, educational backgrounds, working lives and positional titles (t=5.87, -1.96; F=5.60, 11.13, P<0.05) . Career calling is positively related to career satisfaction (r=0.528, P<0.05) . Conclusion: Overall, the level of career satisfaction of nurses is low, especially the financial success. Hospital human resource management should endow more values and meanings on nursing posts, in turn enhance nurses' career calling and career satisfaction.

[Effect of occupational exposure on job burnout in nurses].

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 (ß=0.41, P<0.05) , emotional exhaustion (ß=0.47, P<0.05) , sense of working indifference (ß=0.42, P<0.05) , and low sense of personal accomplishment (ß=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 (ß=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.

[Effect of leader-member exchange on nurses'sense of calling in workplace].

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 (ß= 0.47, P<0.001; ß=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.

Major complications of epidural anesthesia: a prospective study of 5083 cases at a single hospital.

BACKGROUND: We undertook a prospective study of non-obstetric epidurals placed in surgical inpatients at a single teaching hospital to evaluate the incidence of and potential risk factors for major complications of continuous epidural anesthesia. METHODS: Demographic information, details of the epidural procedure, and complications (from the pre-anesthetic period through resolution) were recorded for more than 5000 surgical inpatients who underwent continuous epidural anesthesia in our institution between March 2009 and April 2011. The incidence of and risk factors for major complications were evaluated. RESULTS: During the study period, 5083 patients were interviewed and their details were recorded (98% capture rate). Sixty-nine (1.36%) experienced major complications: epidural hematoma in 1 patient (0.02%), post-operative neurologic deficits in 57 patients (1.12%), post-dural puncture headache in 7 patients (0.14%), and systemic local anesthetic toxicity in 4 patients (0.08%). Only one patient had permanent sequelae: unilateral lower limb paresthesia. Identified risk factors for neurologic deficits were as follows: American Society of Anesthesiologists status II-III, siting in the lumbar region, orthopedic and urologic surgery, multiple attempts to site an epidural, paresthesia during insertion, a history of neuraxial anesthesia, and use of patient-controlled epidural analgesia. CONCLUSIONS: Serious complications were very rare; only one patient had permanent sequelae, and a single epidural hematoma was diagnosed. Post-operative neurologic deficits were more common, but most complications resolved spontaneously within 3 months and they rarely required intervention.

Suppression of spinal cord motoneuron excitability correlates with surgical immobility during isoflurane anesthesia.

BACKGROUND: Recent evidence suggests that the spinal cord is an important site of anesthetic action that produces surgical immobility. Inhalation anesthetics depress the Hoffmann's reflex (H reflex) and F wave, indicating spinal motoneuron suppression. The aim of this study was to assess the correlation between isoflurane-induced immobility and H- and F-wave suppression. METHODS: The baseline H reflex and F wave were measured before anesthesia in 15 adult patients. After induction, 1% end-tidal isoflurane was maintained for 20 min before the H and F waves were reelicited. Using an electric stimulus applied to the forearm and grading the response as movement or no movement, the authors increased or decreased the isoflurane concentration in 0.1% steps, depending on the movement responses. The H and F waves were recorded 20 min after each change of isoflurane concentration. The correlation between H- and F-wave suppression and surgical immobility was analyzed using a paired t test with Bonferroni correction. RESULTS: H-reflex amplitude (2.74 +/- 1.63 mV) and F-wave persistence (70.69 +/- 26.19%) at the highest isoflurane concentration that allowed movement response to a stimulus are different (P < 0.01) from these (1.97 +/- 1.46 mV; 43.16 +/- 22.91%) at the lowest isoflurane concentration that suppressed response. At 0.8% isoflurane, the H-reflex amplitude was 3.69 +/- 1.83 mV with movement and 1.01 +/- 1.14 mV without movement (P < 0.01); F-wave amplitude was 0.29 +/- 0.15 mV with movement and 0.11 +/- 0.06 mV without movement (P < 0.01); F-wave persistence was 80 +/- 22.36% with movement and 34.9 +/- 25.75% without movement (P < 0.01). CONCLUSIONS: The degree of H- and F-wave amplitude and F-wave persistence suppression correlates with movement response, suggesting that isoflurane-suppressive action in the spinal cord plays a significant role in producing surgical immobility.
