目的:研究不同一次性敷料型B-D测试包产品和管腔状检测产品对压力蒸汽灭菌器抽真空不彻底以及空气泄漏检测的敏感性对比和理论分析。方法:严格按照ISO11140-4/5:2006.12.14的测试方法,在低大气压、跨大气压以及高大气压循环条件下通过... 目的:研究不同一次性敷料型B-D测试包产品和管腔状检测产品对压力蒸汽灭菌器抽真空不彻底以及空气泄漏检测的敏感性对比和理论分析。方法:严格按照ISO11140-4/5:2006.12.14的测试方法,在低大气压、跨大气压以及高大气压循环条件下通过抽真空不彻底、空气泄漏以及空气注入等方法对以上不同产品进行全面、系统的研究对比。结果:一次性敷料型B-D测试包产品对抽真空不彻底和空气泄漏具有较好的敏感性以及较稳定的变色指示。但由于不同一次性敷料型B-D测试包产品的结构不同,其对压力蒸汽灭菌器冷空气残留的检测敏感性也存在差异。管腔状检测产品对抽真空不彻底过于敏感,可能会造成假阳性的测试结果;对空气泄漏或注入的监测,其变色性能不稳定,可能会有假阴性的测试结果。 展开更多

Objective To introduce a one stage technique in the reconstruction of mutilated hand with lossof thumb and eventual digits. Methods Tibialis anterior pediculated triple flaps ( TAPTF) including distal lateral leg, dorsalis pedis flaps for skin defect covering and trimmed hallux for thumb reconstruction were presented. Results Mutilated hands in five patients were repaired by the technique with acceptable cosmetic and functional success. A three to twelve months follow-up in three patients resulted in the recovery of protective thermal sensation and pinch action of the reconstructed thumb. The donor sites were free from major disability. Conclusion TAPTF is ideal for one stage reconstruction of the mutilated hand with loss of digits. 展开更多

A case of a 50-year-old pedestrian who was hit by a bike and suffered fractures of both bones of his right leg was presented. Complete clinical and radiographic assessment showed double segmental fractures of the tibia and multisegmental fractures of the fibula. Review of the literature revealed that this fracture pattern was unique and only a single case was reported so far. Moreover, we discussed the possible mechanisms which can lead to such an injury. We also discussed the management of segmental tibial fracture and the difficulties encountered with them. This case was managed by modern osteosynthesis technique with a pleasing outcome. 展开更多

Objective: To study the methods and techniques of free flap transfer bridged by posterior tibial vascular flap in treating large soft tissue defects in low limbs without usable recipient blood vessels. Methods: Based on morphological observation and measurement of arterial pressure and blood flow, an antegrade and a retrograde vascular bridge flaps were designed using the healthy posterior tibial vessels to serve as vascular pedicles to carry two free flaps for transplantation. Results: Eight cases of patient with one or two large soft tissue defects in the leg region were treated by the method. All the bridge flaps and free flaps survived well, and the defects were repaired completely. Conclusions: The results showed that it is an ideal method for using the posterior tibial vessels from the healthy limb to form vascular pedicles in repairing large soft tissue defects in patients without a usable recipient blood vessel. 展开更多
