Fluctuating PEEP (F-PEEP) is a newly developed PEEP in which end-expiratory pressure (EEP) is periodically changed within a certain range. In a dog model with unilateral lung injury induced by the introduction of hydrochloric acid, F-PEEP in which the EEP was periodically changed from 0.5 to 1.5 kPa at periods of 6 min, and conventional PEEP (C-PEEP) with an optimized EEP of 1.0 kPa, were each applied for 30 min. F-PEEP produced a significantly greater improvement of PaO2 and intrapulmonary shunt (QS/QT) than C-PEEP, and at the low EEP phase, the greatest improvement accompanied by an increased dynamic compliance and a large cardiac output was obtained. These results suggest that F-PEEP provides a useful mode of artificial ventilation for the treatment of unilateral lung injury. 相似文献

Sources of P300 attenuation after head injury: Single-trial amplitude, latency jitter, and EEG power
Single trial amplitude, latency jitter, and electroencephalographic (EEG) power were examined as sources of the group difference in averaged P300 amplitude among 15 traumatically brain injured and 20 control individuals in an auditory oddball paradigm. Mean amplitude of the individual trials was highly correlated with the amplitude of the averaged P300, with little additional unique variance attributable to latency jitter or EEG power. The group difference in P300 amplitude was also explained by the mean amplitude of the single trials. These results support the robustness of the event-related potential averaging technique within the paradigm used. 相似文献

神经移位修复臂丛神经根性撕脱伤 总被引:3,自引:2,他引:1
1987年7月~1994年6月,对21例臂丛神经根性撕脱伤采用神经移位修复。其中复合移位4组神经(膈神经、副神经、颈丛运动支、肋间神经)者1例,3组(膈神经、副神经、颈丛运动支)者6例,2组(膈神经、副神经)者9例,1组(膈神经或颈丛运动支或肋间神经)者5例。术中发现臂丛神经变异1例,对4例合并锁骨下动脉损伤者,在神经移位的同时进行血管修复,促进患肢的血液循环,有利于神经的康复。随访到19例,随访时间为8个月~6年2个月,优良率达73.7%。认为,神经移位术是修复神经根性撕裂伤的常规方法,合并血管损伤者也应同时修复,对促进神经功能恢复有利 相似文献

总结胸腹轴型皮瓣早期修复上肢不同部位的深度蛇伤溃疡的经验,评价其应用价值。本组16例,胸脐皮瓣2例,侧胸腹皮瓣1例,髂腰皮瓣5例,下腹皮瓣6例,下腹分叶皮瓣1例,髂腰加下腹Y形皮瓣1例。术后1例皮瓣远端坏死,3例轻度感染,16例断蒂后全部成活。随访3个月~7年,皮瓣质地和弹性均好,手功能基本恢复。认为,带蒂胸腹轴型皮瓣是修复上肢深度蛇伤溃疡理想的方法。 相似文献

A retrospective review was done of 69 children and adolescents (7-17 years old) who underwent 75 arthroscopies of the knee during a 5-year period. Girls were overrepresented (71%). Thirty-eight were children under the age of 16. Of 46 injuries, 34 (74%) happened during sports. Children and adolescents were divided into two age groups based on their presumed state of skeletal maturity (boys 9–15 and girls 7–14 in group I and boys 16–17 and girls 15–17 in group II); meniscal lesions were equally common in the two groups, whereas anterior cruciate ligament tears were more common in older children (NS). Eleven of 17 (65%) anterior cruciate ligament lesions were combined with other intra-articular pathology, most often meniscal tears (9/11). As in other studies, half of the prearthroscopic diagnoses were incorrect. A high frequency of incorrect prearthroscopic diagnoses and of combined lesions justifies arthroscopy as an important diagnostic tool in children and adolescents with a history of twisting knee injury or chronic nonspecific knee problems. Girls practising ball games seem to be especially prone to knee injuries leading to arthroscopy. 相似文献
