目的探讨临床护理人员分层级管理对神经科护理服务质量的影响.方法将我院52名神经科护理人员实施常规管理设为实施前组,2017年3月-2018年2月在常规管理基础上实施分层级管理设为实施后组.比较实施分层级管理前后护理人员的护理质量优良率、护理理论知识及操作技能考核成绩、患者护理满意度.结果实施分层级管理后本组护理人员护理理论知识、操作技能考核成绩均显著高于实施前(P<0.01);护理质量优良率(93.8%)、患者护理满意度(95.0%)显著高于实施前(80.8%、86.5%)(P<0.01).结论对神经科护理人员实施分层级管理,能显著提高护理人员的护理理论水平,增强护理操作技能,改善护理质量,提高患者的护理满意度. 相似文献

Most dissections of extracranial arteries involve some mechanical stress or connective tissue abnormalities. In the absence of these disorders, determining the etiology is challenging. Genetic factors may play an important pathophysiologic role. We report on a 36-year-old male with the right internal carotid artery dissection and a novel genetic variant in the REN gene. Our report offers evidence that mutations in the REN gene could have pathogenic role in arterial dissection. The subject gave written informed consent for the publication of this case report. The authors declare no conflict of interest. 相似文献

Background: Decompressive hemicraniectomy (DHC) is commonly offered after large spontaneous intracerebral hemorrhage (ICH) as a life-saving measure. Based on limited available evidence, surgery is sometimes avoided in the elderly. The association between age and outcomes following DHC in spontaneous ICH remains largely understudied. Objective: The goal of this study is to investigate the influence of older age on outcomes of patients who undergo DHC for spontaneous ICH. Methods: In this retrospective cohort study, inpatient data were obtained from the United States Nationwide Inpatient Sample from 2000 to 2011. Using International Classification of Diseases, ninth revision designations, patients with a primary diagnosis of nontraumatic ICH who underwent DHC were identified. The primary outcome of interest was the association of age to inpatient mortality and poor outcome. Subjects were grouped by age: 18-50, 51-60, 61-70, and more than 70 years. Sample characteristics were compared across age groups using χ2 testing, and univariate and multivariate Poisson Regression was performed using a generalized equation to estimate rate ratios for primary and secondary outcomes. Results: One thousand one hundred and forty four patient cases were isolated. Death occurred in an estimated 28.9% and poor outcome in 86.4%. In multivariate Poisson regression models, there was no difference in hospital mortality or poor outcome by age group. Although younger patients were more likely to be diagnosed with herniation, total complication rate was similar between age groups. Conclusions: Our study results do not provide evidence that age independently predicts in-hospital mortality or poor outcomes. The true influence of age on outcomes is unclear, and further study is needed to determine which factors may be best in selecting candidates for DHC following spontaneous ICH. 相似文献

Goal: Cerebral amyloid angiopathy (CAA) is the second-most common cause of nontraumatic intracerebral hemorrhages (ICH), surpassed only by uncontrolled hypertension. We characterized the percentage, risk factors, and comorbidities of patients suffering from CAA-related ICH in relation to long-term outcomes. Material and Methods: We performed retrospective analyses and clinical follow-ups of individuals suffering from ICH who were directly admitted to neurosurgery between 2002 and 2016. Findings: Seventy-four of 174 (42%) spontaneous nontraumatic lobar ICH cases leastwise satisfied the modified Boston criteria definition for at least “possible CAA.” Females suffered a higher risk of CAA-caused ICH (42 of 74, 56.8%, P= .035). Atrial fibrillation as a major comorbidity was observed in 19 patients (25.7%). Recovery (decrease of modified Rankin scale [mRS]) was highest during hospitalization in the acute clinic. One-year mortality was as follows: 14 of 25 patients (56%) with probable CAA without supporting pathology, 6 of 18, and 8 of 31 patients with supporting pathology and possible CAA, respectively. Only 10 of 74 (13.6%) had favorable long-term outcomes (mRS ≤2). Increasing numbers of lobar hemorrhages, low initial Glasgow Coma Scale, and subarachnoid hemorrhage were significantly associated with poor survivability, whereas statins, antithrombotic agents, an intraventricular hemorrhage, and midline shift played seemingly minor roles. Conclusions: Symptomatic ICH is a serious stage in CAA progression with high mortality. The high incidence of concurrent atrial fibrillation in these patients may support data on more widespread vascular pathology in CAA. 相似文献

A型主动脉夹层(TAAD)发病凶险,临床死亡率极高,外科手术是目前首选的治疗模式。体外循环是TAAD外科手术中不可或缺的环节,但是,由于手术的复杂性以及病情的特殊性,体外循环术后患者出现不同的并发症。而其中,神经系统并发症在临床的发生率较高,如何在体外循环期间采取相应的脑保护措施预防神经系统并发症是当前研究的重点方向。 相似文献
