RESUMO
Objective:To analyze the effects of SBAR(namely situation, background, assessment and recommendation) communication mode-guided scenario simulation exercise on the quality of shift change of practice nurses and the incidence of nursing risks.Methods:From May 2017 to December 2018, 46 nurses interning in the Department of Cardiovascular Medicine of Guangyuan Central Hospital were selected as the control group, and received practice guidance according to the conventional shift change mode; 46 nurses were selected as the research group having the SBAR communication mode-guided scenario simulation exercise from January 2019 to June 2020 in the same department. The evaluation results of the quality of nurses' shift change, the evaluation results of the quality of nurses' succession, and the satisfaction of nurses were compared between the two groups. SPSS 22.0 was used for t test and chi-square test. Results:The evaluation results of 7 items of nurses' handover quality in the research group were better than those in the control group ( P<0.001). The evaluation results of 6 items of nurses' succession quality in the research group were better than those in the control group ( P<0.001). The scores of 5 dimensions in the research group were higher than those in the control group ( P<0.001). Conclusion:The implementation of SBAR communication mode-guided scenario simulation exercise can improve the quality of nurses' shift change and the satisfaction of practice nurses.
RESUMO
Objective To explore the efficacy and mechanism of combined hemodialysis-hemoperfusion in treating patients with end-stage renal failure associated cutaneous pruritus. Methods Eighty-one outpatients and inpatients with end-stage renal failure associated different degree of cutaneous pruritus were randomly divided into treatment group (combined hemoperfusion-hemodialysis, 50 cases) and control group (simple hemodialysis, 31 cases). At the pretreatment and 24 weeks posttreatment, all patients' serum creatinine, blood urea nitrogen, serum total calcium, serum phosphonium, serum intact parathyroid hormone and the intensity of cutaneous pruritus (visual analog scale,VAS) were determined detected. Results Compared with pretreatment, the intensity of cutaneous pruritus of patients in treatment group was obviously alleviated (P<0.01), but it was not alleviated in control group (P>0.05), there was significant difference between two groups (P<0.01). Compared with pretreatment, serum phosphonium and intact parathyroid hormone declined obviously in treatment group [(2.69±0.46) mmol/L vs (0.98±0.39) mmol/L and (632.78±76.89) ng/L vs(342.81±39.71) ng/L] ((P<0.01), but did not decline obviously in control group (P>0.05), there was significant difference between two groups (P<0.01). Conclusions Combined hemodialysis-hemoperfusion can obviously alleviate the intensity of cutaneous pruritus of patients with end-stage renal failure, but simple hemodialysis can not alleviate it,its mechanism may be that it can clean the internal irritant toxin which leads to cutaneous pruritus well.
RESUMO
Objective To explore the correlation and significance between adult nut-cracker phenomenon (NCP) and varicocele. Methods The clinical characters of 226 adult patient (including inpatients and outpatients)with NCP diagnosed by color Doppler ultrasound examination were analyzed retrospectively, whose chief complaints were asymptomatic bematuria or/and orthostatic proteinuria (microalbuminuria). The ratio of left renal vein inner diameter before and after being compressed≥2 was regarded as the criteria of diagnosis of NCP. Among 226 cases, 184 male NCP patients were taken as study group, and the incidence of varicocele was tested. One hundred and fifty-six male adults who had physical examination in the same period and whose ages matched with study group were taken as control group, they were not NCP patients examined by color Doppler ultrasound. The incidence of varicocele was compared between two groups. The indexes associated NCP were examined in detail in study group. Logistic regression analysis was used to study the correlation between NCP and left varicocele. Results There were 184 male patients in study group, among which there were 22 patients with left sub-clinical varicocele (accounted for 11.96%), 47 patients with left varicocele (accounted for 25.54%).The total incidence of varicocole was 37.50%(69/184). There were 156 male adults in control group, among which there were 13 patients with sub-clinical varicocole(accounted for 8.33%), 8 patients with varicocele (accounted for 5.13%).The total incidence of varicocele was 13.46%(21/156). The total incidence of varicocele in study group was significantly higher than that in control group (P=0.000). In study group, there were 22 patients with left sub-clinical varicocele,with average age (24.73±1.03) years. The inner diameter of left renal vein(LRV) in front of spine was (3.65±0.11) mm(a),the inner diameter of LRV at left side of spine was (8.41±0.11)mm(b), and b/a ratio was 2.31± 0.06. The angle between superior mesenterie artery (SMA) and abdominal aorta(AA) was (15.95±0.59)°. There were 47 patients with left varicocele, with average age(26.62±1.74)years. The inner diameter of LRV in front of spine was (3.43±0.08)mm(a),the inner diameter of LRV at left side of spine was (8.72±0.14) mm (b), and b/a ratio was 2.54±0.08. The angle between SMA and AA was (14.54±0.53)°. In study group, Lagistic regression analysis proved that male patients with NCP were complicated with varicocele easier when the angle between SMA and AA became smaller, the inner diameter of LRV at the left side of spine (b)and age increased. Conclusions Male adult patients with NCP are complicated with left varicocele, which is significantly higher than that in non-NCP male adults at the same age. It shows that NCP is one important cause for varicocele and there is a close correlation between NCP and varicocele in male adults.
RESUMO
Objective To study the treating effect of middle and high doses of acetone and aether extracts from Rumex.Japonicus Houtt on mouse thrombocytopenia.Methods 80 BACB/C mice were randomly divided into 5 groups(n=16): negative control group(salad oil),middle dose(0.5 g?kg-1) and high dose(5 g?kg-1)of acetone and aether extracts groups.All mice in various group were injected with cyclophos-phamide(0.3 mL/20 g) by hypodermic for 3 d to set up the thrombocytopenic model;after mouse thrombocytopenic model was successfully set up,the mice were given salad oil,middle and high doses of acetone and aether extracts,respectively,by gastric perfusion,20 d later the mice were executed,the numbers of the platelet,red cells and white cells were determined.Results ①The numbers of platelet numbers of all groups on the 14th day after making model decreased significantly(P0.05).Conclusion Middle and high doses of acetone and aether extracts have obviously curative effect on mouse thrombocytopenia.
RESUMO
<p><b>OBJECTIVE</b>To raise the accuracy of clinical diagnosis of chronic hepatitis B.</p><p><b>METHODS</b>The correlation between the clinical features, biochemical tests (the serum total bilirubin-TBil, albumin-ALB, prothrobin activity-PTA, alanine aminotransferase-ALT, albumin/globulin-A/G, and r-globulin-r-G) and histopathological data in 202 patients with chronic hepatitis B (CHB) were studied.</p><p><b>RESULTS</b>Some of presenting symptoms and signs were obviously associated with histological grade and stage. The grade of necroinflammatory activity of CHB was associated with the rising TBil, ALT, GGT and the declining ALB, A/G and PTA. The coincidence of clinical diagnosis and pathology was highest in mild chronic hepatitis, 63.8%~79.0%; then was in marked chronic hepatitis, 40.0%~62.5%. The coincidence was lowest in moderate chronic hepatitis, 10.0%~28.2%.</p><p><b>CONCLUSIONS</b>Great attention should be paid to the significance of symptoms and signs, meanwhile the standard of clinical diagnosis for moderate chronic hepatitis might be relaxed somewhat.</p>
