BACKGROUND:The traditional orthopedic fixation by C-arm positioning surface is completed, but the large C-arm injury on the human body and the long fixed time increase the suffering of patients. OBJECTIVE:To investigate the X-ray fixed in position within the orthopedic implants, navigation and effect. METHODS:Twenty-six New Zealand white rabbits were randomly divided into C-arm machine group and X-ray group, with 13 in each group. Rabbits in both groups were used to simulate soft tissue foreign body localization, intramedul ary nail implantation at distal fracture end and spinal pedicle screw entry point position. In the C-arm machine group, positioning navigation was conducted with C-arm machine. In the X-ray group, X-ray positioning navigation was used. The positioning and navigation effects were compared between the two groups. RESULTS AND CONCLUSION:(1) Compared with the C-arm machine group, the time required for navigation in the X-ray group targeting soft tissue foreign body localization, fracture distal locking intramedul ary nail implantation and pedicle screw spinal needle point location was significantly shorter (P<0.05);navigation displacement and deviation produced were significantly less (P<0.05). (2) These findings suggested that the X-ray positioning for orthopedic fixation method is relatively simple, with high availability, and can obtain a high performance-price ratio. Meanwhile, the X-ray localization can improve accuracy and shorten the fixed time.

Objective To investigate the prognosis of the intra-aortic balloon pump (IABP) used for patients with acute myocardial infarction and to the risk factors. Methods 88 patients accepted IABP were analyzed retrospectively. Results In spite of overall survival rate (54.5%), under circumstances of percutaneous coronary intervention (PCI), survival rate could reached to 59.9%, with 31.6% and 72.5% in cardiogenic shock group and high-risk group respectively. The time of IABP application increased in drug group. Multivariate Logistic Regression Analysis demonstrated independent-predictor effects of C-reactive protein (CRP), pulmonary infection, renal dysfunction, and wall motion disorder. Moreover, type of coronary artery disease (CAD), renal function, ejection fraction and pre-IABP mean arterial blood pressure could influence the time of IABP application. Conclusion In view of safety, IABP could be used to provide circulatory support for patients with very high risk as well as with cardiogenic shock. Application of IABP could hardly improve in-hospital mortality, and the time of IABP-using could be influenced by many clinical factors, such as type of CAD, renal dysfunction, etc.
