Objective To analyze the characteristics of pathogens causing bloodstream infection (BSI) after cardiovascular surgery, and provide instructions for prevention and treatment of such kind of disease. Methods A retrospective investigation of clinical and pathogenic data of the patients suffering from BSI after cardiovascular surgery in West China Hospital of Sichuan University from January 2015 to December 2016 was performed. There were 61 patients with 36 males and 25 females at average age of 48.2±17.1 years. A percentage of 65.6% (40/61) of the underlying diseases was rheumatic heart disease. Results Sixty-five strains were isolated from the blood culture specimens of the 61 patients. Gram-positive bacteria, gram-negative bacteria and fungi isolates accounted for 56.9% (37/65), 35.4% (23/65), and 7.7% (5/65), respectively. Among these isolates, Streptococcus spp. was predominant (19/65, 29.2%), followed by Staphylococcus epidermidis (8/65, 12.3%), Staphylococcus aureus (6/65, 9.2%), Acinetobacter calcoaceticus- A. baumannii (5/65, 7.7%) and Escherichia coli (5/65, 7.7%). The resistance rate of Streptococcus spp. to erythromycin and clindamycin was 73.4% (14/19) and 63.2% (12/19), while its resistance to cefepime, vancomycin or linezolid was not observed. Staphylococcus spp. showed the resistance rate of 71.4% (10/14) to oxacillin. All of A. calcoaceticus-A. baumannii isolates were multidrug resistant (5/5, 100.0%), and 80.0% (4/5) of them were resistant to imipenem. The isolates producing extended spectrum beta-lactamase accounted for 80.0% (4/5) of E. coli. Conclusion Streptococcus spp. was the common pathogen causing BSI after cardiovascular surgery. Staphylococcus spp. and gram-negative bacilli show high resistance.
目的 提高胸心血管外科患者ICU转出交接班质量，避免护理差错和纠纷。 方法 2010年1月－6月，针对患者转运出现的问题，在查阅文献及专家咨询的情况下，设计制定胸心血管外科ICU患者转出交接单，对患者转出ICU时的病情、用药、并发症等信息进行完善，同时规范交接班签字手续。采用调查问卷方式，对交接单运用效果进行评价。 结果 转出交接单的应用，提高了病房护士对ICU护士交接班质量满意度，除“医嘱单正确执行”、“签字和药物交接班清楚”与运用前满意程度无差异外，其余条目满意程度均有所增加，增加率波动在3.7%～33.4%。 结论 转出交接单使用能够提高ICU患者术后转运交接质量，预防护理差错和纠纷，确保证患者安全。
Facing the increasing cardiovascular disease burden and prevailing population risk factors, the cardiovascular surgery in China was also encountering challenges including imbalances in discipline development, significant divergencies in healthcare quality, lacking of clinical guidelines and domestic critical evidence. The concept of quality control and improvement has been practiced and tested in many disease specialties. Quality improvement programs are urgently needed in China to promote the universal cardiovascular surgery healthcare quality.
In recent years，West China Hospital of Sichuan University actively participated in medical assistance and rescue in Wenchuan，Yushu and Lushan earthquakes. However，professional roles of cardiovascular surgeons in medical assistance and rescue in earthquakes remain unclear because of the particularity of cardiovascular surgery, which often affects the assembly of medical assistance and rescue teams. Thus，we need to explore the necessity for cardiovascular surgeons to join medical rescue teams within 72 hours after earthquake. In this article，medical rescue work of cardiovascular surgeons within 72 hours after 2008 “5•12” Wenchuan earthquake and 2013 “4•20” Lushan earthquake is analyzed and compared to identify professional roles of cardiovascular surgeons in medical rescue within 72 hours after earthquake. It is necessary for cardiovascular surgeons to join medical rescue teams within 72 hours after earthquake.
The incidence of cardiovascular disease remains high, and surgery is an important measure for the treatment of cardiovascular disease. However, cardiovascular surgery is complicated and difficult, and it is one of the departments with the highest rate of allogeneic blood transfusion. Allogeneic blood transfusion significantly increases the complications and mortality of patients, while autologous blood transfusion can effectively reduce allogeneic blood transfusion and adverse reactions. Autologous plateletpheresis technology is a popular autotransfusion method in recent years. This article reviews the autologous plateletpheresis technology and its clinical application in cardiovascular surgery.
Hybrid cardiovascular surgical procedure is an emerging concept that combines the skills and techniques of minimally invasive surgery and interventional catheterization. It allows surgeons to use interventional equipment and techniques during operations, which are traditionally used by physicians, in order to reduce the magnitude of therapeutic interventions and to increase therapeutic effectiveness. This review provides a snapshot of the main application and progress of current hybrid procedures in the field of cardiovascular surgery, including the hybrid therapy of coronary artery disease, congenital heart disease and thoracic aortic aneurysm, also discusses the precondition with which the hybrid procedure should ideally be performed.
ObjectiveTo investigate the clinical application of fresh autologous pericardial patch transplantation in cardiovascular surgery. MethodFrom January 2008 to December 2014, we used fresh autologous pericardial patch as a repair material in surgical treatment of congenital heart disease, valvular and vascular malformation. A total of 239 patients were included (130 males, 109 females), with a mean age of 0.40±13.80 years ranging from 0.25-69.00 years, including 180 infants. ResultThe time of intensive care unit (ICU) stay was 3-15 days and the time of ventilator-assisted breathing was 4-100 hours. Postoperative atelectasis and pleural effusion occured in 8 patients and was cured successfully by closed thoracic drainage and anti-infection therapy. Nine patients died within 30 days after surgery, including 3 deaths caused by low cardiac output syndrome and acute renal failure, 5 deaths caused by multiple organ failure, and 1 death caused by malignant arrhythmia. All patients had no infective endocarditis, thrombosis, hemolysis, blood vessel stenosis, or calcification of pericardial patch. The cause of death was associated with the primary lesion, but not with transplanted pericardium. We followed up 198 patients for 3-64 months. During follow-up, echocardiography showed no patch graft vegetation, thrombosis, perforation or calcification. ConclusionThe fresh autologous pericardium is a good material for repairing cardiac defects.
