离心分离是纳米炸药制备中不可或缺的工序,主要用于物料分离。然而,纳米炸药较大的黏性导致物料很难从离心瓶中快速、完全的收集。传统的处理方式为采用药勺抠取结合绸布擦洗的方式进行收集,费时费力且易掉落线头引入杂质污染。高压水... 离心分离是纳米炸药制备中不可或缺的工序,主要用于物料分离。然而,纳米炸药较大的黏性导致物料很难从离心瓶中快速、完全的收集。传统的处理方式为采用药勺抠取结合绸布擦洗的方式进行收集,费时费力且易掉落线头引入杂质污染。高压水射流枪是通过动力装置产生高压水来冲洗离心瓶壁上纳米炸药湿药团,达到完全收集纳米炸药的一种设备。其操作简单,只有高压水射流为冲洗介质,压力可调,不引入杂质,可大大提高纳米炸药的质量水平和生产效率。 展开更多

The managementvaries according to the literature. We present our experience with this rare complication. Methods:Echocardiography database were reviewed with the term ‘‘hematoma’’ or “hypoechoic mass” for patients whounderwent congenital heart surgery from January 2018 to December 2021 at our institution to identify potentialinterventricular septal hematoma cases. Relevant data of the patients identified were collected. Focus was put onthe presentation, management, outcomes according to patent medical charts and serial echocardiographic reportdata. Results: In total, there were 5 patients included. The mean age and weight at surgery were 5.5 ± 3.6 monthsand 5.5 ± 1.4 kg, respectively. Four patients were diagnosed with ventricular septal defect and the other one beingdouble outlet of the right ventricle. While all patients had intraoperative transesophageal echocardiography, 80%(4 of 5) of Interventricular septal hematoma were revealed intraoperatively. Only one patient received hematomadrainage intraoperatively while the other 3 identified in the operating room were only closely observed. One afterventricular septal defect repair presented continuous dysfunction of the left ventricle at the last follow-up, whilethe others were doing well. All hematomas resolved completely with a mean time to interventricular septal hematomaresolution of 35.8 ± 16.9 days. Conclusion: Infants seem to be at a higher risk for Interventricular septalhematoma following congenital heart surgery. While the majority of interventricular septal hematoma has abenign postoperative course, some may result in ventricular dysfunction. Management strategies may be chosenon a case-by-case basis. 展开更多
