ObjectiveTo investigate the prevention and control measures and procedures for surgical operation safety during the outbreak of new coronavirus pneumonia.MethodsAfter interpreting the diagnosis and treatment plan of new coronavirus pneumonia, the prevention and control plan of new coronavirus pneumonia, and the technical guidelines for prevention and control of new coronavirus pneumonia infection in medical institutions, we formulated and improved the prevention and control measures and procedures for surgical safety in our hospital.ResultsA total of 567 patients were operated in our hospital from January 22, 2020 to February 10, 2020, including 501 were operated in the surgical center and 66 were operated in the interventional center. Among all the cases, there were 303 emergency operation and 264 scheduled or limited operation. In the emergency operation, the top three were 130 cases of caesarean section (42.9%), 63 cases of abdominal digestive system operation (20.8%) and 31 cases of skull operation (10.2%). In the scheduled or limited operation, the top four were 65 cases of benign diseases of the eye (24.6%), 57 cases of tumor (21.6%), 53 cases of orthopedic surgery (20.1%), and 25 cases of coronary angiography (9.4%). All the patients were successfully completed the operation and recovered well after the operation. No serious surgical complications or infection-related complications occurred.ConclusionDuring the outbreak of new coronavirus pneumonia, surgery and epidemic prevention and control can be carried out by adjusting and optimizing measures and procedures.
ObjectiveTo investigate the safety and feasibility of early mobilization in critically ill patients with femoral catheters, and to provide reference for guiding clinical rehabilitation training. MethodsThe literature on the safety and feasibility of early mobilization in critically ill patients with femoral catheters included in PubMed, EMbase, OVID, Springer-link, Wiley Online Library, and Web of Science up to June 2021 was searched, and relevant data were extracted for analysis. ResultsSeventy-two papers were initially screened, and 12 papers that met the criteria were finally included, covering 1 056 patients, and 489 patients had femoral catheters. Patients underwent 6 495 sessions of physical therapy, and a total of 62 patients had adverse events, including 14 (2.86%, 14/489) patients with catheter-related adverse events. ConclusionAlthough early mobilization in critically ill patients with femoral catheters may lead to adverse catheter-related events, the incidence is low. Therefore, the associated risks and benefits should be weighed in clinical practice, and femoral catheter is not recommended as a contraindication for early mobilization in critically ill patients.

Venous thromboembolism (VTE) is a high-risk complication in hospitalized patients, especially in patients with orthopedic surgery, neurosurgery, thoracic surgery, cardiac surgery and tumor surgery. It is also a significant cause of patients’ unexpected death and perioperative death. Through establishment of norms of VTE management system and organizational structure, formulation of perfect VTE risk assessment system and prevention and treatment scheme for hospitalized patients, training of all the medical staff for related knowledge, and test operation of the system in key departments, we established a hospital standardized system of venous thromboembolism prevention and management. Our VTE prevention and treatment work achieved good results through multidisciplinary collaboration.
ObjectiveTo investigate the feasibility and safety of transcatheter aortic valve replacement (TAVR) through apical approach for aortic regurgitation of large annulus.MethodsFrom November 2019 to May 2020, 10 male patients aged 64.50±4.20 years with aortic valve insufficiency (AI) underwent TAVR in the Department of Cardiovascular Surgery, Xijing Hospital. The surgical instruments were 29# J-valveTM modified and the patients underwent TAVR under angiography. The preoperative and postoperative cardiac function, valve regurgitation, complications and left ventricular remodeling were summarized by ultrasound and CT before and after TAVR.ResultsA total of 10 valves were implanted in 10 patients. Among them, 1 patient was transferred to the aortic arch during the operation and was transferred to surgical aortic valve replacement; the other 9 patients were successfully implanted with J-valve, with 6 patients of cardiac function (NYHA) class Ⅱ, 4 patients of grade Ⅲ. And there was a significant difference between preoperation and postoperation in left ventricular ejection fraction (44.70%±8.78% vs. 39.80%±8.48%, P<0.05) or aortic regurgitation (1.75±0.72 mL vs. 16.51±8.71 mL, P<0.05). After 3 months, the patients' cardiac function was good.ConclusionTAVR is safe and effective in the treatment of severe valvular disease with AI using J-valve.

ObjectiveTo systematically review the clinical utilization of robotic bronchoscopes in diagnosis of pulmonary nodules, including MonarchTM and IonTM platforms, and then evaluate the efficacy and safety of the procedure. MethodsPubMed, EMbase, Web of Science and Cochrane Central Register of Controlled Trials databases were searched by computer for literature about the biopsy of pulmonary nodules with robotic bronchoscope from January 2018 to February 14, 2022. The quality of research was evaluated with Newcastle-Ottawa Scale. RevMan 5.4 software was used to conduct the meta-analysis. ResultsFinally, 19 clinical studies with 1 542 patients and 1 697 targeted pulmonary nodules were included, of which 13 studies used the IonTM platform and 6 studies used the MonarchTM platform. The overall diagnostic rate of the two systems was 84.96% (95%CI 62.00%-95.00%), sensitivity for malignancy was 81.79% (95%CI 43.00%-96.00%), the mean maximum diameter of the nodules was 16.22 mm (95%CI 10.98-21.47), the mean procedure time was 61.86 min (95%CI 46.18-77.54) and the rate of complications occurred was 4.76% (95%CI 2.00%-15.00%). There was no statistical difference in the outcomes between the two systems. Conclusion Robotic bronchoscope provides a high efficacy and safety in biopsy of pulmonary nodules, and has a broad application prospect for pulmonary nodules diagnosis.
