Objective To investigate the feasibility and efficacy of iliofemoral endovascular therapy for the treatment of chronic ischemia of lower extremities due to arterial atherosclerosis. Methods During the period of September 2005-January 2009 percutaneous endovascular angioplasty and stent implantation were performed in 15 consecutive patients with CTA-proved chronic occlusive iliofemoral artery disease. The patients included 11 males and 4 females with a mean age of (72.1 ± 5.9) years (ranged from 61 to 82 years). Before the procedure, all patients underwent clinical and imaging assessments, including Fontaine classification, ankle-brachial pressure index (ABI), and lower limb computed tomography angiography (CTA). According to the length, morphology and location of the occlusive segment, different types of stents were employed together with pereutaneous transluminal angioplasty (PTA) to treat the occluded lilac or superficial femoral artery. At the end of the procedure, distal angiogram was performed to assess the success of the procedure and to exclude thromboembolism or dissection complications. After PTA, the residual stenosis < 30% and/or pressure gradient < 10 mmHg were defined as technical success. Clinical success was identified when patient's clinical symptoms were improved by one or more grade according to Fontaine classification. Results Technical success was totally achieved in all patients with no occurrence of complication. Recanalization of the occluded artery was performed preferably by retrograde ipsilateral femoral artery approach in 5 patients and by contralateral access using the crossover aorta technique in 10 patients. PTA was performed in all patients after stent release to open the occluded vessel to its normal diameter. The mean length of the lilac arterial segment covered with 8 stents was (7.6 ± 1.4) cm (ranged from 6 cm to 10 cm). The mean diameter ± SD of the iliac stents was 9.5 mm ± 1.4 mm (ranged from 8 mm to 12 mm). The mean length of 5 superficial artery implanted stents was (4.5 ± 1.1) cm (ranged from 4 cm to 6 cm). The mean ABI before treatment and six months after treatment was 0.64 (range 0.41 to 0.89) and 0.76 (range 0.50 to 0.95), respectively. The difference in ABI between pre-interventional and post-interventional procedure was statistically significant (t = -4.64, P < 0.01). Clinical improvements according to Fontaine classification were obtained in all patients, in whom technical success was achieved (100%). Conclusion Endovascular interventional procedure is a safe and effective treatment for iliofemoral arterial occlusive disease due to arterial atherosclerosis. PTA combined with subsequent stent implantation can well improve the patient's quality of life as well as the hemodynamics of lower extremities, which is very important for preserving the diseased limb for a long period of time.

Objective? To explore the effects of Omaha system-based nursing intervention on patients after percutaneous coronary intervention (PCI). Methods? Totally 200 patients receiving PCI in Ningbo First Hospital from February 2016 to November 2017 were selected using convenient sampling and divided into the control group (n=100) and the observation group (n=100) according to the random number table. Patients in the control group received conventional nursing care, while patients in the observation group received nursing care based on Omaha system. The incidence of postoperative vascular complications was evaluated between the two groups. Self-Depression Scale (SDS), Self-Anxiety Scale (SAS) and the nursing satisfaction questionnaire were used to evaluate the effects of intervention. Results? The incidence rate of postoperative vascular complications was lower in the observation group than in the control group (P＜ 0.05); the SAS and SDS scores of the observation group were lower than those of the control group (P＜0.05); and the satisfaction at discharge of the observation group was higher than that of the control group (P＜ 0.05). Conclusions? Omaha system-based nursing interventions can reduce the incidence rate of postoperative vascular complications, ameliorate patients' negative emotions and improve their satisfaction, which is worth promoting in clinical practice.

Objective? To explore the effects of symposium involving patients and their family members on health education in patients with acute myocardial infarction after percutaneous transluminal coronary intervention (PCI). Methods? Totally 86 patients with acute myocardial infarction receiving PCI in Ningbo First Hospital from January 2017 to June 2018 were selected continuously and divided into the control group (n=43) and the observation group (n=43). Patients in the control group received conventional health education which combined oral education and education manuals, while patients in the observation group symposium-based health education which involved both patients and their family members on the basis of conventional education after PCI. Both groups received health education for 4 weeks. Health knowledge about acute myocardial infarction, rehabilitation initiative, postoperative complication and satisfaction with overall nursing were compared between the two groups before and after intervention. Results? The health-related knowledge of the patients with acute myocardial infarction in the observation group 4 weeks after intervention scored (94.3±4.0), higher than that of the control group, which was (78.4±5.1), and there was statistically significant difference (t=8.285, P＜ 0.05). The scores of five dimensions of rehabilitation initiative (coordination with therapy, compliance, needs for rehabilitation, emotions post frustration and encouragement from family members and nurses) of the observation group were higher than those of the control group (t=4.726, 5.114, 3.975, 7.116, 5.893; P＜0.05). The incidence rate of postoperative complication in the observation group was 9.30%, lower than that of the control group, which was 30.23%, and there was statistically significant difference (χ2=5.939, P＜0.05). The nursing satisfaction of the observation group was 96.73%, higher than that of the control group, which was 83.78%, and there was statistically significant difference (χ2=4.904, P＜0.05). Conclusions? The symposium involving patients and their family members for patients with acute myocardial infarction after PCI can improve the patients' disease-related knowledge, satisfaction with overall nursing and rehabilitation initiative, and reduce the postoperative complications effectively.

Objective:To establish an intelligent management system and explore its application in the management of high-value consumables in Interventional Operating Room.Methods:Supply and processing and distribution (SPD) combined with the intelligent management system was applied in the Intervention Center at Ningbo First Hospital of Zhejiang Province in October 2019. High-value consumables managed with traditional information management between October 2018 and September 2019 were included into the control group, while those managed with SPD combined with the intelligent management system from October 2019 to September 2020 were included into the observation group. The high-value consumable system and inventory compliance rate, average daily inspection time, average daily claim time, timely supply of consumables, return rate of unused consumables, and nurse satisfaction under the two different management modes were compared.Results:The coincidence rates of the high-value consumable system inventory and actual inventory in the observation group and the control group were 98.26% (226/230) and 85.21% (196/230) , respectively; the average daily inspection time, (67.44±1.42) min in the observation group was less than (108.00±2.51) min in the control group, and the average daily claim time, (53.41±5.24) min was less than (118.22±4.68) min in the control group; the total rate of untimely supply of consumables and unreturned unused consumables in the observation and control groups were 3.46% (138/3 986) and 20.86% (881/4 224) , respectively; and the satisfaction of nurses in the two groups were 93.75% (135/144) and 63.89% (92/144) . The differences between the two groups were all statistically significant ( P<0.05) . Conclusions:The construction and application of the intelligent consumable management system can effectively improve the standardization and refinement of the management of high-value consumables in the Interventional Operating Room, and reduce the operating cost of the department.
