ObjectiveTo compare clinical outcomes between coronary artery bypass grafting (CABG)and off-pump coronary artery bypass grafting (OPCAB)for high-risk coronary artery disease (CAD)patients with high European System for Cardiac Operative Risk Evaluation (EuroSCORE). MethodsA total of 211 CAD patients undergoing surgical treatment in the Department of Cardiovascular Surgery, Anhui Provincial Hospital Affiliated to Anhui Medical University from June 2007 to July 2013 were enrolled into this study, including 52 patients receiving CABG and 159 patients receiving OPCAB. Predicted risk of operative mortality (PROM)of each patient was calculated by EuroSCORE. Patients with PROM≥6 were stratified into high-risk subgroups. Clinical outcomes were compared between CABG and OPCAB patients, as well as incidence of cardiovascular events, angina and stroke within 30 postoperative days in high-risk subgroup patients. ResultsOPCAB and CABG group patients had similar left main disease. There was no statistical difference in the number of distal anastomosis between OPCAB (2.75±0.82)and CABG group patients (2.83±0.58) (P > 0.05). Operation time[ (3.92±0.79)hour vs. (6.83±1.53)hour], thoracic drainage[ (983.14±802.39)ml vs. (1 620.40±879.32)ml], blood transfusion[ (1 289.30±668.08)ml vs. (2 325.30±491.98)ml], length of ICU stay[ (3.90±1.33)days vs. (5.08±1.78)days], and mechanical ventilation time[ (9.63±3.32)h vs. (13.76±3.79)h] of OPCAB group patients were significantly shorter or lower than those of CABG group patients (P < 0.05). There was no statistical difference in 30-day mortality between OPCAB and CABG group patients (1.26% vs. 3.85%, P > 0.05). Among high-risk subgroup patients, the odds ratio of stroke within 30 postoperative days in CABG was 5.7 (95%CI 1.28-25.09, P < 0.05)compared with OPCAB group patients, and the incidence of cardiovascular events and angina within 30 postoperative days were similar between the 2 subgroups. ConclusionsPostoperative mortality and number of distal anastomosis are not significantly different between CABG and OPCAB patients, but OPCAB can significantly reduce operation time, thoracic drainage, blood transfusion, length of ICU stay and mechanical ventilation time compared with CABG. For high-risk patients with high EuroSCORE, OPCAB can better reduce the incidence of postoperative stroke compared with CABG.
Objective To study effects of mitral valve replacement(MVR) on the old with mitral valve diseases(MVD). Methods The documents of 265 cases undergoing MVR were reviewed, who aged 60 years old or over between June 1991 and June 2003. Demographices, clinical preoperative conditions, indications to surgery, early postoperative course and long-term outcome were collected via hospital documents and outpatient follow-up. Many risk factors were analysed. Results Follow-up rate amounted to 93.7%(236/252). The mortality was 4.9% (13/265) within 30 days. Heart failure and renal failure were the main cause of death. Compared with younger patients(lt;60 years old), long-term survival rate was lower in the old, 5-year 87.52% vs 96.84%, 10-year 81.23% vs 94.87%. There were 15 late deaths(0.17% case/M), most of whom died of heart failure, cancers and lung infections. Risk factors for MVR in the old included New York Heart Association class Ⅳ, diabetes, and lung incompetence. Conclusions The patients with MVD over 60 years old tended to present high postoperatively mortality and morbidity.
目的 探讨层流手术室动态空气菌落数超标的高危因素。 方法 回顾分析2010年3月－2011年11月168台次特别洁净层流手术室动态空气样品细菌培养结果的资料，依据层流手术室动态环境下空气样品是否超过10个菌落形成单位（CFU）/m3将168例空气样品细菌培养的资料分别命名为超标组和正常组。超标组有56台次，正常组有112台次。将超标组与正常组就有关手术持续的时间、参与手术的医务人员数量、参观人数、手术过程中开门的次数、是否为污染手术、手术及麻醉设备是否在手术过程中有搬动、是否为接台手术、患者术前1 d是否更衣洗澡以及麻醉方式等因素进行分析比较。 结果 层流手术室动态空气菌落数超标与参观手术的人数、术中开门次数、手术类型、术中有无设备搬动及患者术前1 d是否进行更衣洗澡等因素有关（P＜0.05），而与手术持续时间、参加手术的人员数量、是否接台手术及麻醉方式等无关（P＞0.05）。 结论 参观手术的人数＞3人、术中开门次数＞10次、手术类型为污染手术、术中有设备搬动及患者术前1 d未进行沐浴更衣是层流手术室动态空气菌落数超标的高危因素。
ObjectiveTo investigate the efficacy and safety of percutaneous transhepatic gallbladder drainage (PTGBD) combined with early laparoscopic cholecystectomy (LC) in the treatment of elderly patients with high-risk acute cholecystitis.MethodsThe clinical data of 128 elderly patients with high-risk acute cholecystitis admitted to Department of Hepatobiliary Surgery in Dazhou Central Hospital from January 2015 to January 2019 were retrospectively analyzed. Among them, 62 patients underwent PTGBD combined with early LC treatment (PTGBD+early LC group), 66 patients underwent PTGBD combined with delayed LC treatment (PTGBD+delayed LC group). Comparison was performed on the operative time, intraoperative blood loss, conversion to laparotomy rate, postoperative indwelling time, postoperative hospitalization time, total hospitalization time, and complication.ResultsPTGBD was successfully performed in all patients, and the symptoms were relieved within 72 hours. There was no significant difference in operative time, intraoperative blood loss, conversion to laparotomy rate, postoperative indwelling time, postoperative hospitalization time, and total complication rate between the two groups (P>0.05), but the total hospitalization time of the PTGBD+early LC group was shorter than that of the PTGBD+delayed LC group (P<0.001). There was no second operation and death in both two groups. The 128 patients were followed-up for 2–50 months with a average of 19 months. Results of follow-up after operation showed that the patients did not complain of obvious abdominal pain, abdominal distension, chills, fever, jaundice, and other discomforts.ConclusionsFor elderly patients with high-risk acute cholecystitis, early LC is a safe and effective treatment for patients with good overall condition after PTGBD. It can not only shorten the total hospitalization time, but also significantly shorten the time of tube-taking and improve the quality of life of patients. It has important clinical application value.
ObjectiveTo summarize the clinical experience in the treatment of high-risk patients with severe aortic valve disease by transcatheter aortic valve implantation (TAVI) via heart apex approach and to evaluate the early efficacy.MethodFive patients who underwent TAVI via heart apex approach from September 2017 to February 2019 in Henan Thoracic Hospital were retrospectively analyzed, including 3 males and 2 females, aged 65-84 (74.6±4.5) years.ResultAll operations were performed through a small left incision into the thoracic cavity (3-5 cm), and then through the J-Valve transport system, the aortic valve was successfully released via heart apex after precise positioning under digital subtraction angiography. One patient developed ventricular fibrillation during the operation, and the operation was completed with the assistance of emergency femoral arteriovenous catheterization cardiopulmonary bypass; one patient underwent percutaneous coronary intervention first because of severe coronary stenosis; one patient had paroxysmal atrial fibrillation during the perioperative period, and had hepatorenal insufficiency and thrombocytopenia after the operation, and was improved after medical treatment; one patient had perivalvular leak during the operation, and was improved after re-implantation of the valve; one patient was in stable condition during operation and recovered smoothly after operation. Surgery was successful in all 5 patients. The follow-up time was 2-19 months, and the early clinical effect was good.ConclusionThe short-term clinical efficacy of TAVI via heart apex approach in the treatment of high-risk severe aortic valve disease is definite and safe, but the long-term and medium-term effects need to be further evaluated.
Objective To develop an evaluation tool for the screening of high risk population for oral complications in critically ill patients, which can be performed accurately and scientifically. Methods Basing on the related foreign oral assessment scale, combined with the method of brainstorming, expert consultation, method of clinical status and so on, the item pool of the assessment scale was determined. Five nursing experts and two oral experts assessed the content validity and 50 ICU nurses were tested. Then, the screening accuracy of the assessment scale was proved by application in 100 critically ill patients selected randomly. Results The Cronbach’s a coefficient of final version of the High Risk Assessment Scale for Oral Complications in Critically Ill Patients (including seven parts contents of oral health assessment and oral pH value test) was 0.815, the content validity index (Sr-CVI/Ave) was 0.932. The results of 50 nurses to the 91.2% assessment items of the assessment scale were very important and important. For screening related indicators of oral complications in high-risk patients, the sensitivity of the assessment scale was 97.53%, the specificity was 94.11%, the positive predictive value was 98.75%, the negative predictive value was 88.89%, and the crude agreement was 95%. Conclusion There are good reliability, validity and a high accuracy of screening test in the High Risk Assessment Scale for Oral Complications in Critically Ill Patients. It can be used for screening patients at high risk for oral complications in critically ill patients, and help clinical nurses to complete the oral health status of the critically ill patients quickly.
ObjectiveTo investigate the diagnosis and classification of chronic obstructive pulmonary disease (COPD) in high risk populations living in metropolitan communities of Beijing. MethodsDuring January 2011 to December 2012,a cross-sectional survey including questionnaires and pulmonary function tests were performed in high risk populations of COPD (aged≥40 years with a history of smoking or chronic bronchitis) at 6 communities in Dongcheng District of Beijing. For those confirmed to have COPD,the dyspnea was rated by the modified Medical Research Council Dyspnea Scale (mMRC),and the frequency of acute exacerbations in the last year was recorded. The patients were classified by the Global Initiative for Chronic Obstructive Lung Disease (GOLD 2011) classification criteria. ResultsA total of 932 individuals,including 689 males (73.9%,aged 60.8±12.5 years) and 243 females(26.1%,aged 59.8±12.1 years),who had risk factors of COPD were included in the screening. COPD was confirmed in 203 patients,with the prevalence of 21.8%,and among whom only 31 cases (15.3%) had been diagnosed as COPD in the past. According to the revised GOLD classification in 2011,96(47.2%),38(18.7%),56(27.5%),and 13(6.4%) patients were classified into group A,B,C and D,respectively. The proportion of subgroup C1 (FEV1%pred <50% and the number of exacerbation in the last year <2) in group C was 71.4% (40/56). ConclusionIn the metropolitan communities of Beijing,screening the population with predisposing factors can increase the early diagnosis of COPD,which is often delayed by the lack of significant symptoms. The high proportion of patients in group C in this population implies that disease screening in high risk populations may be helpful for the prevention and treatment of COPD.
