Chinese Journal of Tissue Engineering Research 2015;(26):4258-4264
BACKGROUND:Open fractures often present soft-tissue defects, high-risk infection, and fracture with bone defect, often lead to more postoperative complication, defect of limb function, and bring great difficulties to clinical treatment. There is some controversy in the treatment of such fracture. Relevant animal experiment and clinical study become the hotspot in recent years. OBJECTIVE:To review some controversy about open fracture treatment and latest research. METHODS:A computer-based online search of China National Knowledge Infrastructure database and PubMed was performed for articles published from January 2005 to January 2015. Key words included “Open fracture, Evaluation and prognosis of injury, Antibiotics, Debirdement, Treatment of fracture, Wound repair”. More than 100 literatures were retrieved, and 47 articles met the inclusion criteria. RESULTS AND CONCLUSION:After a large number of animal experiments and clinical application, open fracture debridement, prevention of infection, implant selection and evaluation of prognosis had been deeply studied, especialy the study of implant treatment of bone defects. Metal three-dimensional printer has changed the traditional concept of implant. Nano titanium dioxide /PEEK bioactive composite materials have become a hot research in recent years.
3.Management of cardiac perforation and pericardial tamponade complicating percutaneous balloon mitral valvuloplasty
Journal of Interventional Radiology 1994;0(03):-
Objective To determine the diagnostic and therapeutic approach of cute cardiac perforation and tamponade complicating percutaneous balloon mitral valvuloplasty. Methods and Results Percutaneous balloon mitral valvuloplasty was performed in 772 patients with rheumatic mitral stenosis from May 1992 to Dec. 2001, 9 were diagnosed cardiac perforation, 2 which developed pericardial tamponade which was successfully controlled by contrast and X ray guided pericardiocentesis using a subxiphoid approach. Conclusions Only a minority of cardiac perforation resulted from PBMV developed pericardial tamponade. The latter could be controlled safely and effectively by contrast and X ray guided pericardiocentesis using a subxiphoid approach.The diagnosis of pericardial tamponade during or after PBMV relies on a strong clinical suspicion, and contrast and X ray guided pericardiocentesis should be carried out without echocardiography for patients in unstable state.
