Application of buried auricular point combined with Wenjing Sanhan prescription in arteriosclerosis obliterans patients with resting pain

BACKGROUND Research on the combined use of ear acupoint embedding beans and warming meridians with cold-dispersing formulas for alleviating resting pain in patients with arteriosclerosis obliterans(ASO)remains limited.AIM To explore the therapeutic efficacy of auricular point embedding beans combined with Wenjing Sanhan prescription in alleviating resting pain in patients with lower-limb ASO.METHODS A total of 100 patients with ASO experiencing resting pain who were treated at our hospital from January 2022 to January 2023 were enrolled.They were randomly allocated into two groups using a double-blind approach.The control group was treated using a warming meridian with a cold-dispersing formula,while the study group received additional treatment with ear acupoint embedding beans.The clinical efficacy,ankle-brachial artery pressure ratio,hemorheological indicators,and traditional Chinese medicine symptom scores were compared between the two groups.RESULTS The clinical efficacy rate in the study group was significantly higher(94.00%)than that in the control group(72.00%,P<0.05).Moreover,the ankle-brachial artery pressure ratio was significantly higher in the study group after treatment(P<0.05).Hemorheological parameters,including whole blood viscosity,plasma viscosity(1.83±0.11)mPa/s,fibrinogen levels(3.30±0.21)g/L,platelet adhesion rate(49.87%±10.51%),and erythrocyte aggregation index(1.79±0)were improved in the study group compared to the control group.In addition,the scores for decreased skin temperature(1.41±0.26),intermittent claudication(1.30±0.20),and resting pain(1.23±0.31)were significantly lower in the study group than those in the control group(all P<0.05).The level of oxidative stress in the study group also exhibited significant improvement(P<0.05),and the levels of inflammatory factors were considerably lower than those in the control group.CONCLUSION The combination of ear point embedding beans and Wenjing Sanhan prescription demonstrates promising clinical efficacy in alleviating resting pain associated with ASO.

Analysis of the Effect of Problem-Oriented Nursing Intervention on Patients with Lower Extremity Arteriosclerosis Obliterans in Vascular Surgery

Objective: To analyze the effect of problem-oriented nursing intervention on patients with lower extremity arteriosclerosis obliterans (ASO) in vascular surgery. Methods: The clinical data of 128 patients with lower extremity ASO in vascular surgery were selected and randomly divided into groups A and B, with 64 cases each. Group A is the control group, and Group B is the observation group. Group A received the routine nursing intervention, and Group B received the problem-oriented nursing intervention. The compliance, self-care ability, psychological state, quality of life, and nursing satisfaction of the two groups of patients were evaluated based on various indicators. Results: After the intervention, the evaluation of self-care ability (ESCA) score of the patients in Group B was higher than that of Group A, and the symptom checklist-90 (SCL-90) score was lower than that of Group A. The differences were significant (t = 10.019, t = 3.118, P < 0.01). After the intervention, the World Health Organization Quality of Life Brief (WHOQOL-BREF) index scores of the two groups increased and the increase in Group B was significantly higher than Group A (P < 0.001). The compliance rate of Group B (62/ 96.88%) was higher than that of Group A (52/ 81.25%), and the difference was extremely significant (χ2 = 8.020, P < 0.01). Conclusion: Problem-oriented nursing intervention for patients with lower extremity ASO in vascular surgery improved the patient’s self-care ability, and quality of life, reduced the patient’s negative emotions, and enhanced their overall satisfaction.

Clinical and prognostic features in asymptomatic and symptomatic patients with arteriosclerosis obliterans

Background: Patients with arteriosclerosis obliterans (ASO) often have co-existing atherosclerotic diseases. The purpose of this study was to examine the clinical features of patients with ASO, including the overlap of atherosclerotic risk factors, characteristics of car-diovascular events, and clinical prognosis. Method: We enrolled 205 consecutive patients who had ankle brachial index (ABI) of ?0.9 between January 2008 and December 2009. Fontaine (F) classification and clinical background were evaluated and clinical events including mortality and major adverse cardiocerebro-vascular events (MACCEs) were determined. Results: There was a high prevalence of each risk factor. Sixty- five percent of subjects had three or more of the four overlapping risk factors, including hypertension, dia- betes, dyslipidemia, and smoking. After a maximum follow-up of 800 days, the incidence of MACCEs and mortality was 46% and 10%, respectively. We divided the patients into two groups according to the presence of ASO symptoms (F1 and F2-4) and compared the incidence of events. The incidence of MACCEs and mortality in the F2-4 group was significantly higher than that in the F1 group (P = 0.048, P = 0.044, respectively). After excluding lower extremity revascularization, coronary artery disease was a common cause of MACCEs, and the mortality rates after MACCEs increased in a stepwise manner according to F classification severity (P = 0.028). Conclusion: Patients with ASO had overlapping coronary risk factors and a high incidence rate of cardiovascular events. The incidence of coronary events was common, especially in symptomatic patients, and the mortality rates after MACCEs were high in accordance with F classification severity.
