随着世界现代医药学和我国传统医药学的深入发展,中药和西药的在临床上的联合应用非常普遍。而目前在临床中西药合用过程中往往只注重中西药合用的有效性,却忽视了因配伍禁忌而可能出现疗效降低、产生或增加毒副作用的不合理用药。这不仅造成资源的浪费,同时也增加药源性疾病的发生。这应引起广大医药工作者及患者的高度重视。笔者参考近年来有关文献资料,就临床中西药合用的配伍禁忌问题进行归纳论述。
Objective To explore the current situation and influencing factors of self-regulatory fatigue in maintenance hemodialysis (MHD) patients, so as to provide good dialysis treatment for MHD patients, reduce their level of self-regulated fatigue and improve their quality of life. Methods The convenient sampling method was used to select the MHD patients in the Wenjiang Hemodialysis Center of West China Hospital of Sichuan University between April 12 and April 30, 2022. The patients were investigated by self-made basic information scale and self-regulatory fatigue scale. Results A total of 131 patients were included. The average score of self-regulatory fatigue was 53.47±6.45, cognitive dimension was 20.21±2.39, emotional dimension was 20.85±2.85, behavioral dimension was 12.40±3.63. The results of multiple linear stepwise regression analysis showed that age, duration of dialysis and educational background could inversely predict the score of self-regulatory fatigue (P<0.05). Conclusions MHD patients have a high level of self-regulatory fatigue. Clinical nurses can make individual dialysis programs according to the actual situation of MHD patients, improve their self-regulated level and physical and mental health, and improve the quality of life of MHD patients.
ObjectiveTo discuss the application of Miller pyramid teaching method in the competency training of new nurses in hemodialysis room and evaluate the effect.MethodsFourteen new nurses in hemodialysis room adopting conventional teaching method from January 2017 to December 2018 were retrospectively selected as the control group; from January to December 2019, another 14 new nurses in hemodialysis room were prospectively selected as the trial group and Miller pyramid teaching method was adopted. After three months of training, the theory and operation of the two groups of new nurses were assessed, and the post competency was assessed by using the Competency Inventory for Registered Nurse, and the teaching satisfaction was assessed by using the self-designed questionnaire on the teaching effect satisfaction of new nurses in hemodialysis room. The data of the two groups were compared.ResultsThe theoretical examination score (91.54±5.89 vs. 83.86±6.45), operational examination score (96.89±3.65 vs. 90.58±5.15), score of Competency Inventory for Registered Nurse (186.66±4.89 vs. 163.76±6.89), and teaching satisfaction (4.56±0.72 vs. 3.56±0.97) in the trial group were all higher than those in the control group, the differences were statistically significant (P<0.05).ConclusionMiller pyramid teaching method is feasible to train the post competency of new nurses in hemodialysis room, which is helpful to improve the theoretical basis, operational skills, post competency, and teaching satisfaction of new nurses in hemodialysis room.
Objective To understand the incidence of frailty in maintenance hemodialysis (MHD) patients, and to explore the correlation and influencing factors of frailty in MHD patients, so as to provide some basis for the intervention of frailty in MHD patients. Methods Patients who underwent MHD in the Department of Nephrology of West China Hospital of Sichuan University from January to March 2021 were selected. Frail scale and Pittsburgh Sleep Quality Index (PSQI) were used for evaluation, and the influencing factors of frail in patients with MHD and its correlation with frail were analyzed. Results A total of 141 patients with MHD were included, including 57 cases without frailty (40.43%), 71 cases in early frailty (50.35%), and 13 cases in frailty (9.22%). 54 cases (38.30%) had very good sleep quality, 56 cases (39.72%) had good sleep quality, 24 cases (17.02%) had average sleep quality, and 7 cases (4.96%) had very poor sleep quality. The frailty of MHD patients was positively correlated with age (rs=0.265, P=0.002), PSQI (rs=0.235, P=0.005) and magnesium (rs=0.280, P=0.001). Logistic regression analysis showed that the influencing factors of MHD patients’ frailty were gender [odds ratio (OR) =4.321, 95%confidence interval (CI) (1.525, 12.243), P=0.006], PSQI [OR=1.110, 95%CI (1.009, 1.222), P=0.032], magnesium [OR=122.072, 95%CI (4.752, 3 135.528), P=0.004], hypertension [OR=0.112, 95%CI (0.023, 0.545), P=0.007] and other diseases [OR=0.102, 95%CI (0.019, 0.552), P=0.008]. Conclusions The incidence of frailty in MHD patients is high. Gender, PSQI, magnesium, hypertension and other diseases are the influencing factors of frailty in MHD patients, and there is a correlation between frailty and sleep. It is suggested that renal medical staff should pay more attention to the assessment of MHD frailty and sleep, and carry out multi-disciplinary personalized intervention to improve the quality of life of MHD patients.
At present, the whole lifecycle management of vascular access for hemodialysis in China is still in its early stages. Faced with a large group of chronic kidney disease patients, hospitals at all levels lack systematic and continuous nursing management models. To address the issue of lacking continuous and effective nursing management of vascular access for dialysis during the period from hospitalization for autologous arteriovenous fistula surgery to outpatient maintenance hemodialysis treatment, this article introduces the background, specific implementation methods, and preliminary results of the new model of integrated medical and nursing follow-up management of vascular access for patients with hemodialysis during hospitalization and outpatient period constructed by the Wenjiang Hemodialysis Center of West China Hospital, Sichuan University. The purpose is to explore a new model for continuous and effective management of vascular access for hemodialysis patients.
The emergence of real-time functional magnetic resonance imaging (rt-fMRI) has provided foundations for neurofeedback based on brain hemodynamics and has given the new opportunity and challenge to cognitive neuroscience research. Along with the study of advanced brain neural mechanisms, the regulation goal of rt-fMRI neurofeedback develops from the early specific brain region activity to the brain network connectivity more accordant with the brain functional activities, and the study of the latter may be a trend in the area. Firstly, this paper introduces basic principle and development of rt-fMRI neurofeedback. Then, it specifically discusses the current research status of brain connectivity neurofeedback technology, including research approaches, experimental methods, conclusions, and so on. Finally, it discusses the problems in this field in the future development.
ObjectiveTo investigate the current situation of stress load and professional benefit of hemodialysis nurses during the outbreak period and the remission period of coronavirus disease 2019 (COVID-19) epidemic, and discuss the differences in stress load and professional benefit of hemodialysis nurses between the two periods.MethodsIn February 2020, 119 hemodialysis nurses from three hemodialysis centers in Sichuan Province were selected as the respondents. Using the Stress Overload Scale and the Questionnaire of Nurses’ Perceived Professional Benefits, questionnaire survey was conducted in February 2020 and April 2020, respectively. Paired-sample t test was used for analysis.ResultsA total of 109 valid questionnaires were collected. The scores of stress load of hemodialysis nurses in outbreak period and remission stage were 3.00±1.26 and 2.17±1.16, respectively, of which the scores of event load dimension were 3.49±1.15 and 2.31±1.27, respectively, and the scores of individual vulnerability dimension were 2.59±1.19 and 2.05±1.06, respectively; the professional benefit scores of hemodialysis nurses in outbreak and remission were 4.19±0.83 and 4.21±0.78, respectively. The difference in stress load of the same group of hemodialysis nurses between different time periods was statistically significant (P<0.05), while there was no significant difference in professional benefit (P>0.05).ConclusionsDuring the outbreak of COVID-19 epidemic, the stress load of hemodialysis nurses was ata medium level, and that in the remission stage of COVID-19 epidemic was at a low level; the professional benefit of nurses in the outbreak and remission period was at a high level. The stress load status of hemodialysis nurses was different between different periods of the epidemic. We should take incentive mechanism or targeted psychological intervention measures to improve the professional benefit level of nurses.
ObjectiveTo understand the maintenance hemodialysis (MHD) patients’ intention to exercise rehabilitation and discuss the influencing factors.MethodsFrom January to March 2019, 141 MHD patients’ intention to exercise rehabilitation was investigated by cross-sectional survey, and the influencing factors of MHD patients’ intention to exercise rehabilitation were analyzed by multiple linear stepwise regression.ResultsA total of 141 questionnaires were issued and 139 valid ones were recovered. The mean score of exercise rehabilitation intention of MHD patients was 39.99±9.29, which was in the middle and high level. Age [unstandardized partial regression coefficient (b)=−5.277, 95% confidence interval (CI) (−8.640, −1.915), P=0.002], educational level [b=2.412, 95%CI (1.161, 3.663), P<0.001], and 6-minute walking distance [b=3.526, 95%CI (0.032, 7.021), P=0.048] were the influencing factors of exercise rehabilitation intention of MHD patients.ConclusionMHD patients have high intension to exercise rehabilitation, and special attention should be paid to elderly patients and patients with low education level in clinical work to improve their intension to exercise rehabilitation.
Objective To understand the current situation of eHealth literacy of maintenance hemodialysis (MHD) patients and analyze the influencing factors to improve the eHealth literacy of MHD patients. Methods Using cross-sectional survey method, MHD patients in West China Hospital of Sichuan University were selected as the subjects between February and April 2022. eHealth Literacy Scale (eHEALS) was used to investigate the status of eHealth literacy, and the influencing factors of MHD patients were analyzed. Results A total of 194 MHD patients were investigated. The total eHEALS score of MHD patients was 24.55±9.14. The results of generalized linear regression showed that education level, medical payment method, age, frequency of internet forums, interest in internet health knowledge search, and Baidu search engine (a common channel for searching disease information online) were the influencing factors of MHD patients’ electronic health literacy. Conclusion The electronic health literacy level of MHD patients is low, so renal medical staff should pay attention to the electronic health literacy of MHD patients and develop targeted interventions to help patients better manage their own health problems.
Objective To analyze the long-term outcome of modified Morrow surgery (interventricular septal cardiomyectomy) in the treatment of hypertrophic obstructive cardiomyopathy (HOCM) in children. Methods The clinical data of the children with HOCM (aged≤14 years) who underwent modified Morrow surgery from January 2010 to August 2022 in Guangdong Provincial People's Hospital were retrospectively analyzed, including changes in hospitalization status, hospitalization outcomes, perioperative period, and long-term 15-lead electrocardiogram and echocardiography. Results A total of 29 patients were collected, including 22 males and 6 females, aged (5.00, 12.00) years. Five (17.9%) patients had New York Heart Association (NYHA) heart function grade Ⅲ or Ⅳ. Ventricular septal myectomy was performed in all patients. All 29 patients survived and their cardiac function recovered after operation. Before discharge, right bundle branch block was observed in 2 patients and left bundle branch block in 6 patients. After surgery, the left atrial diameter decreased (36.58±6.00 mm vs. 28.83±3.97 mm, P<0.05). Left ventricular end-systolic diameter increased (17.19±5.47 mm vs. 20.82±7.40 mm, P<0.05], and peak pressure gradient of left ventricular outflow tract decreased (87.13±31.38 mm Hg vs. 17.52±16.15 mm Hg, P<0.01). The thickness of ventricular septum decreased (23.13±8.45 mm vs. 18.22±5.92 mm, P<0.05). The systolic anterior motion of mitral valve disappeared and mitral regurgitation was reduced (5.14±3.56 cm2 vs. 1.28±1.18 cm2, P<0.01). The flow velocity and peak pressure gradient of right ventricular outflow tract were also reduced in the patients who underwent right ventricular septal myocardial resection. The average follow-up of the patients was 69.03±10.60 months. All the patients survived with their NYHA cardiac function grading Ⅰ or Ⅱ. No new-onset arrythmia event was found. Echocardiography indicated that the peak pressure gradient of the left ventricular outflow tract remained low (87.13±31.38 mm Hg vs. 19.26±17.80 mm Hg, P<0.01). Moderate mitral regurgitation occurred in 2 patients, and left ventricular outflow tract obstruction with moderate mitral regurgitation occurred in 1 patient after simple right ventricular septal myocardial resection. Conclusion Right ventriclar or biventricular obstruction is frequent in the children with HOCM and they usually have more symptoms before surgery. Modified Morrow surgery can effectively relieve outflow tract obstruction and improve cardiac function in these patients. The long-term outcome is satisfactory. However, the posterior wall of the left ventricle remains hypertrophic. Also, there is an increased risk of a conduction block.
