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.
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.
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.
Working Group on Extracorporeal Life Support, National Center for Cardiovascular Quality Improvement developed guidelines on patient blood management for adult cardiovascular surgery under cardiopulmonary bypass, aiming to standardize patient blood management in adult cardiovascular surgery under cardiopulmonary bypass, reduce blood resource consumption, and improve patients outcomes. Forty-eight domestic experts participated in the development of the guidelines. Based on prior investigation and the PICO (patient, intervention, control, outcome) principles, thirteen clinical questions from four aspects were selected, including priming and fluid management during cardiopulmonary bypass, anticoagulation and monitoring during cardiopulmonary bypass, peri-cardiopulmonary bypass blood product infusion, and autologous blood infusion. Systemic reviews to the thirteen questions were performed through literature search. Recommendations were drafted using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system. After five rounds of experts discussions between 2023 and 2024, 19 recommendations were finally formed.
In 2022, many excellent clinical studies emerged in the field of cardiovascular surgery. Selecting papers published in The New England Journal of Medicine and other top medicine and cardiology journals, this review focused on the research progress on 7 topics in the field of cardiovascular surgery: coronary artery surgery, vascular surgery, valvular surgery, structural heart disease, congenital heart disease, heart transplantation, perioperative management, and special population.
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。
