【摘要】 目的 探讨降低冠状动脉支架植入术后拔管所致血管迷走神经反射（vasovagal reflexs，VVR）的护理干预措施及效果。 方法 将2011年1-3月冠状动脉支架植入患者120例随机分为两组，对照组58例，试验组62例，对照组按常规方法拔管，试验组除常规方法外根据患者不同情况予针对性护理干预。 结果 120例患者中共发生VVR 10例，其中对照组发生8例，试验组发生2例。两组比较差异有统计学意义（Plt;0.05）。 结论 冠状动脉支架植入手术患者实施针对性的护理干预可有效降低血管迷走神经反射的发生，提高手术成功率。【Abstract】 Objective To investigate the nursing intervention measures and effects on reducing the vasovagal reflexs (VVRs) after the coronary stent extubation. Methods The clinical data of 120 patients who underwent coronary stenting between January and March 2011 were retrospectively analyzed. Patients were randomly divided into control group (n=58) treated with conventional coronary stent extubation and experiment group (n=62) treated with conventional coronary stent extubation and professional nursing intervention care. Results In 120 patients, VVRs occurred in 10 including 8 in the control group and 2 in the experiment group. The difference between the two groups was significant (Plt;0.05). Conclusion The coronary stent implantation with specific nursing interventions can effectively reduce the vascular vagal reflex, and leads to a higher success rate of the surgery.
ObjectiveTo explore whether education and management of medical care integration can improve asthma control. MethodsA prospective, 12-month, cohort study was undertaken in a real-world setting based on Australasian severe asthma network (ASAN). A total of 516 patients with stable asthma were consecutively recruited, who received education and management of medical care integration, and step-wise anti-asthma regimens determined by physicians’ standard practice. Furthermore, inhaled corticosteroid (ICS) adherence, lung function, asthma symptom control and exacerbation were assessed at 1, 3, 6, and 12 months. ResultsAt the end of 12 months, ICS adherence (47.7% vs. 81.5%, P<0.05), lung function, and asthma symptoms were assessed by asthma control text (ACT) [20 (16, 23) vs. 23 (21, 24), P<0.05], which were significantly improved in comparison to the status at baseline, and 86.0% of patients achieved total/well-controlled level of asthma. The exacerbation (14.2% vs. 36.2%, P<0.01) and hospitalizations (8.5% vs. 15.3%, P<0.01) because of asthma for the following year significantly decreased compared with those in the past year. The multivariate regression analysis indicated that poor ICS adherence (RR=1.52, 95%CI 1.02 to 2.25, P=0.039), depression symptoms (RR=1.19, 95%CI 1.05 to 1.34, P=0.007), and exacerbation during the past year (RR=2.81, 95%CI 1.49 to 5.27, P=0.001) were associated with an increased risk of future exacerbation. ConclusionIn a real-world setting, most of asthmatics achieve total/well-controlled asthma by education and management of medical care integration including shared decision-making between physicians and patients and step-wise anti-asthma regimens. ICS adherence and depression symptoms independently predict asthma exacerbations, and strengthening education and management of medical care integration, esp. psychological nursing, would improve asthma control levels.
Objective To compare the clinical and hemodynamic results of patients undergoing transcatheter aortic valve replacement (TAVR) with different vascular approaches. Methods We retrospectively analyzed the baseline status, procedure status, procedure-related clinical complications defined by Valve Academic Research Consortium-2 consensus document, and postoperative hemodynamic results of patients with severe aortic stenosis who underwent TAVR between April 2012 and January 2019 in West China Hospital of Sichuan University. Results A total of 436 patients were enrolled, including 58 patients undergoing surgical cutdown and 378 patients undergoing percutaneous puncture. The prevalence of tumor in the surgical cutdown group was higher than that in the percutaneous puncture group (8.62% vs. 2.65%, P=0.037), while the other baseline characteristics, including age, male proportion, body mass index, and Society of Thoracic Surgeons scores, were similar between the two groups (P>0.05); the proportion of patients with aortic regurgitation equal to or greater than a moderate degree in the surgical cutdown group was lower than that in the percutaneous puncture group (22.41% vs. 35.98%, P=0.043), and there was no statistically significant difference in other preoperative cardiac ultrasound-related indicators (P>0.05). The procedure success rate was high in both groups (96.55% vs. 98.68%, P=0.236). Immediately after operation, the incidences of new-onset left bundle branch block (43.10% vs. 24.87%, P=0.004), severe bleeding (12.07% vs. 4.23%, P=0.030), and mild bleeding (20.69% vs. 3.44%, P<0.001) were higher in the surgical cutdown group than those in the percutaneous puncture group, and the postoperative hemodynamics indicated that there was no statistically significant difference in maximum blood flow velocity between the two groups [(2.37±0.52) vs. (2.50±1.67) m/s, P=0.274]. At the 1 year follow-up, the cardiac death rate (5.17% vs. 3.17%, P=0.696) and all-causes mortality rate (8.62% vs. 8.47%, P=1.000) between the two groups were not statistically different.Conclusions Compared with percutaneous puncture, surgical cutdown is associated with a higher incidence of bleeding events, while the incidence of other clinical complications such as vascular complications and the postoperative hemodynamic outcomes were similar.
Objective To explore the effects of 4-phenylbutyric acid (4-PBA) on idiopathic pulmonary fibrosis (IPF) using a murine model of bleomycin (BLM)-induced pulmonary fibrosis. Methods Pulmonary fibrosis was induced in C57BL/6 mice by intratracheal injection of BLM. A total of 120 mice were randomly allocated into three groups: BLM group, BLM+4-PBA group, and control group. Pathology of lung tissue was analyzed to evaluate the degree of pulmonary fibrosis, and the survival of the mice was noted. The expression levels of the endoplasmic reticulum stress markers, activating transcription factor 6 (ATF6) and C/EBP homologous protein (CHOP), were analyzed in lung tissues from mice. Results BLM induced significant collagen deposition in the lungs of the mice, which was alleviated by 4-PBA. 4-PBA also dramatically improved the pulmonary function and increased the survival rate in the BLM+4-PBA group compared with that in the BLM group. Both the mRNA and protein expression levels of ATF6 and CHOP were significantly reduced in mouse lung tissue after 2 weeks of 4-PBA treatment. Conclusions 4-PBA treatment could alleviate BLM-induced pulmonary fibrosis in mice via the attenuation of endoplasmic reticulum stress.
