Objective To summarize the general situation of perioperative venous thromboembolism (VTE) and summarize the perioperative antithrombotic strategies. Methods Domestic and international literatures and guidelines on antithrombotic therapy were collect and reviewed. Results VTE was common during the perioperative period. Reasonable assessment of each patient’s condition during the perioperative period, as well as reasonable use of anticoagulant, antiplatelet drugs, and hemostatic agents could reduce the incidence of VTE events during the perioperative period. Conclusions Clinicians need to properly assess the timing of the usage and discontinuation of antithrombotic drugs, weigh the risk of thrombosis and bleeding, develop a rational and scientific antithrombotic strategy based on the specific circumstances of each patient. Simultaneously, hemostatic agents need to be prescribed perioperatively to reduce the incidence of thromboembolic complications.

Methods: Five hundred perioperative records of patients with incision Ⅰ were randomly chosen and surveyed in 2009. A questionnaire for prophylactic use of antimicrobial was designed. The indication of antimicrobial use, the species, combination, timing and drug duration were analyzed. Results: Our of 500, 495 used antimicrobial and 80 were unreasonable; 540 kinds of antimicrobial were used, included cephalosporin 453 cases (83.89%), penicillin class (including plus enzyme inhibitors) in 26 cases (4.81%), quinolone 44 cases (8.15%). Cefazolin sodium (178 patients, 32.96%) ranked first, second was cefazolin sodium (151, 27.96%). Conclusion: Perioperative use of antimicrobial prophylaxis in patients with incision Ⅰ is reasonable, but standardization management should be strengthened in the indication, species, and duration.
ObjectiveTo analyze the clinical outcomes of extended thymectomy for myasthenia gravis (MG) patients under different surgical approaches, and to determine the factors affecting the prognosis of MG. MethodsThe MG patients who underwent extended thymectomy from January 2014 to March 2021 in our hospital were retrospectively collected. According to the surgical approach, they were divided into a subxiphoid group and an intercostal group, and the perioperative results and prognosis were compared between the two groups. A “good outcome” was defined as complete stable remission (CSR), pharmacological remission (PR) or minimal manifestations state (MMS); a “poor outcome” was defined as outcomes worse than MMS. Univariate and multivariate logistic regression analyses were performed to assess the factors associated with the good outcomes. ResultsA total of 187 MG patients were included in the study, including 82 males and 105 females, with a median age of 50 (36, 60) years. There were 134 patients in the intercostal group and 53 patients in the subxiphoid group. Compared with the intercostal group, although the operation time of the subxiphoid group was longer [200.0 (172.0, 232.0) min vs. 141.0 (118.0, 169.0) min, P<0.001], the intraoperative blood loss was less [10.0 (10.0, 20.0) mL vs. 20.0 (10.0, 50.0) mL, P<0.001], the postoperative hospital stay was shorter [3.0 (2.5, 4.0) d vs. 5.0 (3.0, 7.0) d, P<0.001], and the incidence of complications was lower [1 (1.9%) vs. 26 (19.4%), P=0.001]. A total of 159 (85.0%) patients were followed up for a median period of 46 (13, 99) months, with a good outcome rate of 90.6% and CSR rate of 33.3%. There were no statistical differences in PR, MMS or overall good outcome rates between the two groups (P>0.05). Multivariate logistic analysis showed that age≤50 years was an independent predictor for "good outcome" of MG patients. ConclusionExtended thymectomy via subxiphoid for MG is a safe, feasible and effective surgical approach.
The technique of transcatheter aortic valve implantation has become increasingly mature. Although the transapical approach has a certain degree of minimally invasive trauma, it still has the characteristics such as heart beating without cardiopulmonary bypass, and the low technical requirements of catheter guide wire. In particular, the valve path is short and coaxial, which is easy to manipulate, and pure regurgitation and stenosis can be easily operated and are not subject to the limit of peripheral artery stenosis. It is still one of China's main approaches for transcatheter aortic valve replacement. Its perioperative management still has specific features and differs from the femoral artery approach. In addition, there is little relevant literature abroad. Therefore, domestic experts in this field were organized to discuss the development of perioperative management specifications to provide reference and techniques support for developing this field in China and further improve the quality of clinical operation and perioperative management. It will provide more safe and more effective medical services to these patients.
ObjectiveTo explore the influence of enhanced recovery after surgery (ERAS) on intestinal flora in patients with colorectal cancer.MethodsBy convenient sampling method, 60 patients with colorectal cancer were selected from August 2018 to December 2019 in the Department of Gastrointestinal Surgery of West China Hospital of Sichuan University and randomly divided into ERAS group and traditional treatment group (traditional group). Among them, the perioperative clinical management was carried out according to the ERAS management and traditional treatment process in the the ERAS group and in the traditional group, respectively. The fresh fecal samples were collected within 24 h after admission and the first natural defecation after operation. The bacterial 16 Sr DNA V3–V4 region was sequenced by Illumina MiSeq sequencer, and the results were analyzed by bioinformatics.ResultsA total of 60 patients with colorectal cancer were included, 30 cases in the traditional group and 27 cases in the ERAS group (3 people temporarily withdrew from the study). There were no significant differences in the basic informations between the two groups (P>0.05). ① Before or after operation, there were no significant differences in Shannon index and Simpson index between the two groups. The difference between preoperative and postoperative comparison in the same group was also not statistically significant (P>0.05). ② Beta diversity analysis showed that there was no significant difference in community composition between the traditional group and the ERAS group before operation, and there was a clear boundary between the traditional group and the ERAS group after operation. ③ At the phylum level, compared with the preoperative abundance, the postoperative abundance Firmicutes decreased by 26.5% and 5.5% in the traditional and ERAS group, respectively; Bacteroidetes increased by 21.6% and 4.7% in the traditional and ERAS group, respectively; Proteobacteria increased by 7.2% and 2.2% in the traditional and ERAS group, respectively. At the genus level, compared with the preoperative abundance, the postoperative abundance of Bacteroides in the traditional group increased by 17.6% and in the ERAS group decreased by 1.6%; Bifidobacterium decreased by 1.8% and 1.3% in the traditional group and in the ERAS group, respectively.ConclusionsERAS does not affect species diversity of intestinal flora. Although ERAS has some damage to structure of intestinal flora, it is weaker than traditional process, so it is more conducive to reconstruction and restoration of intestinal microecological environment.
The apical displacement of tricuspid valve leaflets complicated with significantly enlarged, thin and fibrotic wall of the right ventricle is prone to dysfunction of right heart. Therefore, the myocardial protection for the right ventricle is important. Based on the pathological changes, an algorithm of perioperative myocardial protection strategy is summarized. Firstly, we should clearly know that the right ventricular myocardium with severe lesions is much different from the unimpaired myocardium, because it is now on the margin of failure; secondly, right heart protection should be regarded as a systematic project, which runs through preoperative, intraoperative and postoperative periods, and requires close collaboration among surgeons, perfusionists, anesthesiologists and ICU physicians. In this article, we try to introduce the systematic project of the right heart protection, in order to improve the outcome of this population.
Anxiety is a strong behavioral and psychological reaction with fear components, while depression is a mental disorder dominated by high or low mood, both of which are accompanied by cognitive and behavioral changes, and are common comorbidities in patients with heart disease. Cardiac surgery is one of the important factors which trigger specific emotional and physiological reactions of patients. Persistent or initial depression and anxiety after surgery will not only increase surgical complications, short- or long-term mortality and medical costs, but also seriously affect patients' social function and quality of life. With the transformation of bio-psycho-social medical model, it is necessary to evaluate the perioperative psychological state and biological risk of patients undergoing cardiac surgery. This article reviews the characteristics, related mechanisms and therapeutic interventions of anxiety and depression in patients undergoing cardiac surgery.
Inadvertent perioperative hypothermia (IPH) is one of the common complications of surgery, which can lead to a series of adverse consequences. In recent years, with the deepening development of precision medicine concepts, establishing predictive models to identify the risk of IPH early and implementing targeted interventions has become an important research direction for perioperative management. This article reviews the current research status of IPH predictive models in adults, focusing on the research design, modeling methods, selection of prediction factors, and prediction performance of different predictive models. It also explores the advantages and limitations of existing models, aiming to provide references for the selection, application, and optimization of relevant predictive models.
In tracheal resection and reconstruction, a technically demanding, complex, and high-risk procedure, management of the anastomotic site significantly impacts postoperative outcomes and long-term quality of life. However, comprehensive studies detailing perioperative anastomotic management strategies in tracheal reconstruction remain scarce. This review summarizes perioperative management strategies for tracheal reconstruction, covering preoperative assessment, surgical techniques, and other key aspects. It also highlights future research directions and challenges, aiming to provide clinicians with a systematic guide to perioperative management in tracheal reconstruction.
Objective To review the progress of perioperative treatments for patients of Parkinson’s disease and hip fractures. Methods The related literature of treatments for patients of Parkinson’s disease and hip fractures were reviewed and analyzed from the aspects such as the perioperative management, selection of operation ways, and prognosis. Results The patients of Parkinson’s disease are more likely to sustain hip fractures because of postural instability and osteoporosis. The perioperative treatments for patients of Parkinson’s disease and hip fractures should be determined by orthopedists, neurologist, anesthesiologist, and physical therapist. There is still controversy about the selection of operation and surgical approach. And the prognosis of patients of Parkinson’s disease and hip fractures are associated with the severity of Parkinson’s disease. Conclusion There are few clinical studies about the patients of Parkinson’s disease and hip fractures. The mid-term and long-term functional outcomes of patients of Parkinson’s disease and hip fractures are unsufficient. And the best treatments of patients of Parkinson’s disease and hip fractures need to be further explored.
