阶段性健康教育对老年食管癌患者术后配合行为的影响 总被引:2,自引:0,他引:2
目的探讨阶段性健康教育对老年食管癌患者术后配合行为的影响。方法将51例患者按入院先后分为观察组(26例)和对照组(25例)。观察组实施阶段性健康教育,即住院当日、术前1~3d、术后回病房、术后第1天、拔除胃管当日、出院前1d,由管床护士实施不同内容的健康教育;对照组实施传统健康教育。术后1周评价两组患者术后的配合行为及术后并发症的发生率。结果观察组术后配合行为显著优于对照组(均P〈0.01);并发症发生率显著低于对照组(P〈0.05)。结论对老年食管癌手术患者实施阶段性健康教育,可提高患者的术后配合行为,降低并发症的发生。 相似文献

BACKGROUND: Cognitive impairment after stroke associates with various factors, such as age, educational years, etc. Besides concerning about the recovery of limb function after stroke, we should also focus on the rehabilitation of cognition. Moreover, we'd better pay attention to the control of all the risk factors of stroke, and improve the quality of life in stroke patients.
OBJECTIVE: To analyze the factors that affect cognitive impairment after stroke.
DESIGN: A related factors analysis.
SETTINGS: Department of Neurology of Dalian Port Hospital and Dalian Second People's Hospital.
PARTICIPANTS: Totally 148 stroke inpatients were selected from Department of Neurology, Dalian Port Hospital and Dalian Second People's Hospital from April 2004 to December 2005, including 100 males and 48 females, aging 45-75 years with an average age of (67±8) years; Their educational years ranged 2-10 years with an average of (6.1±3.7) years; The disease course ranged 15-30 days; All were right-handed. Inclusive criteria: All were accorded with the diagnostic standard set by the Fourth National Academic Meeting for Cerebrovascular Disease; Confirmed by CT or MRI; Informed consents were obtained from all the subjects.
METHODS: After the disease conditions were stable, the patients were assessed with Wechsler memory scale (WMS) and Wisconsin card sorting test (WCST). WMS included forward and backward recitation of numbers and short-term memory (verbal memory, visual recognition). The number of times for correct and wrong classifications in WCST and the time to complete the trail making tests A and B were recorded. The focal volume, area and layer were recorded at 24 hours after admission. The general data of the patients were recorded, including name, sex, age, educational years, history of hypertension, history of diabetes mellitus. Electroencepalograph (EEG) was examined to record the wave shape, blood lipids were detected, and the cognition related indexes were analyzed with the Pearson correlation analysis. The correlation between cognitive indexes after stroke and the influencing factors were analyzed with multiple linear regression analysis.
MAIN OUTCOME MEASURES: ① Correlation between cognitive indexes and imaging indexes; ② Influencing factors for cognitive indexes after stroke.
RESULTS: All the 148 stroke patients were involved in the analysis of results. ① Correlation between cognitive indexes and CT indexes: There were obvious negative correlations between numerical symbol and focal layer (r =-0.234, P < 0.05), as well as between verbal memory and the focal area and volume (r =-0.363, -0.279, P < 0.05); Trail making test A had obvious positive correlation with focal area and volume (r =0.256, 0.256, P < 0.05). Results of multiple linear regression analysis: Correct classification was correlated with triglyceride (partial wave and θ wave (partial regression coefficient=0.231-0.908, P < 0.05); Verbal memory was correlated with EEG α wave, focal volume, sex, educational years and diabetes mellitus (partial regression coefficient=0.219-1.017, P < 0.05-0.01). Visual recognition had correlation with educational years and hypertension (partial regression coefficient=0.326, -1.163, P < 0.01). Trail making tests A and B were correlated with focal volume (partial regression coefficient=4.680, -18.561, P < 0.05).
CONCLUSION: The factors that affect the cognitive function after stroke include sex, age, educational years, hypertension, diabetes mellitus, triglyceride, EEG wave shape, and the focal area, volume and layer 相似文献

对60例病毒性肝炎患者进行肝穿刺活检,结果发现,临床与病理诊断的符合率为46.6%,其中,急性肝炎的诊断符合率最低(23.8%),慢性迁延型肝炎(慢迁肝)为44.8%;HBsAg阳性首次发病的患者中,急性乙型肝炎仅为11.2%(2/18);临床诊断的慢性活动型肝炎(慢活肝)仅为病理检出的25.7%(9/35);肝炎患者中脾肿大,凝血酶元时间延长、A/G值<1.2、抗HBcIgM阳性可作为慢活肝与慢迁肝鉴别的重要指标。这些对提高病毒性肝炎临床分型诊断的准确率及指导临床治疗有意义。 相似文献

用低蛋白饮食方法建立豚鼠胆色素结石模型,共设对照、致石、维生素C修复、丹参修复和对照修复等5组,规定时间内处死动物,用放射免疫、固相酶联免疫、生物化学等方法检测肝细胞内环—磷酸腺甙(cAMP)、环—磷酸鸟嘌呤(cGMP)、钙调素(CaM)、钙,三磷酸腺甙酶(Ca2+-ATPase)、磷酸化酶a等水平。致石组豚鼠肝脏细胞内cAMP和磷酸化酶a升高,而cGMP,CaM和Ca2+-ATPase下降,表明肝细胞钙稳态呈失调状态。维生素C和丹参可调整肝细胞的上述改变,说明维生素C和丹参具有维持肝细胞钙稳态的作用。 相似文献
