ABSTRACT
Objective:To construct an evaluation index system for the risk factors of peripheral venous indwelling catheter failure in adults.Methods:Through literature review, focus group interview method and Delphi method, an evaluation index system for risk factors of peripheral venous indwelling catheter failure in adults was established.Results:The recovery rate of the two round were both 100%; the authority coefficient was 0.939, the coordination coefficient was 0.452 and 0.315 respectively ( χ2=607.88, 502.45, P<0.05). Finally an evaluation index system for adult peripheral venous indwelling needle catheter failure risk factors including puncture factors, patient factors, indwelling needle placement factors, indwelling needle maitenance and withdrawal factors and 54 second-level indicators were formed. Conclusions:The construction of adult peripheral venous indwelling needle catheter failure risk factor assessment system is reasonable and comprehensive in content, which provides reference for clinical nurses to evaluate and prevent the failure of adult peripheral venous catheter failure.
ABSTRACT
Objective:To explore the mediating effect of self-perceived aging between family care and quality of life (QOL) of elderly type 2 diabetes patients, and to provide the evidence for improving the QOL of elderly type 2 diabetes patients.Methods:The convenience sampling method was used to investigate 215 elderly patients with type 2 diabetes by using the Brief Ageing Perceptions Questionnaire, the Family APGAR Index and the Diabetes Specific Quality of Life Scale, and statistical analysis was performed using SPSS20.0 software.Results:The self-perceived aging score of the elderly patients with type 2 diabetes was (49.90±12.11), the family care score was (7.17±2.53), and the QOL score was (65.89± 12.07). Family care score was negatively correlated with QOL score in elderly patients with type 2 diabetes ( r value was -0.480, P<0.01), self-perceived aging score was negatively correlated with family care score ( r value was -0.472, P<0.01), and positively correlated with QOL score ( r value was 0.688, P<0.01). The mediating effect test showed that self-perceived aging played a complete mediating role between family care and QOL in elderly type 2 diabetes patients, and the mediating effect accounted for 86.51% of the total effect. Conclusions:Self-perceived aging is the mediating variable of family care and QOL, and establishing positive self-perceived aging is conducive to improving the QOL of elderly patients with type 2 diabetes.
ABSTRACT
OBJECTIVE@#To observe the effect of occlusal interference on the afferent pathway of the trigeminal nerve and neuronal excitability in the trigeminal subnucleus caudalis (SPVC) of rats by electrical stimulation of the trigeminal ganglion (TG) and extracellular recordings of SPVC activities.@*METHODS@#Twenty male Wistar rats were randomly divided into control group and model group (=10). In the model group, occlusal interference for 30 consecutive days was induced using light-cured flowable resin on the right maxillary molars. During occlusal interference, the pain sensitivity was scored with von Frey Fibers in the masseter. Simultaneous recordings of electrical activities from the SPVC, electrocardiogram, body temperature and electromyogram of the breath muscles of the anesthetized rats were performed, and the responses evoked by electrical stimulation of the TG were analyzed.@*RESULTS@#Compared with the control rats, the rats in the model group showed significantly increased pain sensitivity scores ( 0.05). Train stimulation (0.2 ms, 1 mA, 30 s, 100 Hz) of the TG significantly increased the discharge frequency of the SPVC only in the rats in the model group ( < 0.05).@*CONCLUSIONS@#The functional activities of the pain afferent pathway of the trigeminal nerve can be electrophysiologically monitored by electrical stimulation of the TG and extracellular recordings of SPVC activities in rats. Occlusal interference can increase the excitability of the neurons in the SPVC and enhance their sensitivities to TG afferent activation, suggesting the neural plasticity of the pain afferent pathway.
