查询词典 occlusion

IMPLICATIONS: By increasing the length of infusion lines, the time until an infusion pump triggered a pressure occlusion alarm was critically prolonged, especially at low infusion rates, as is often used for vasopressor support of unstable patients.

通过增加输注线的长度，输注泵出发压力闭塞闹铃的时间被推迟了。特别是在低输注率的时候，因为它被不稳定患者用作血管压力支持。

Objective To evaluate the efficacy and safety of the method of holding wire temporarily for occlusion of ventricular septal defect. Methods 32 patients with VSD diagnosed by transthoracic echocardiography and left ventriculography were suitable to interventional therapy.

编者按：封堵器置入时保留导丝的方法封堵VSD安全、高效，特别适用于难度较大的VSD的封堵，该方法简化了更换封堵器时需重建轨道的程序，缩短了操作及透视时间，减少了并发症的发生，手术成功率高，疗效可靠，值得推广。

All patients underwent femoral venipuncture catheterization examination to insert the occluder. Patent ductus arteriosus and ventricular septal defect needed femoral artery puncture operation. Aortic arch descending part or left ventricular ventriculography was performed before occlusion to further clarify the diagnosis and surgical indications and help choose occluder type. Angiography was repeated after surgery to judge the effect. Patients with atrial septal defect and ventricular septal were defected with conventional transthoracic echocardiography monitoring and evaluation.

采用大鼠大脑中动脉栓塞模型、沙土鼠全脑缺血再灌模型和小鼠脑缺血再灌3种动物模型，研究复方葛根素对脑缺血再灌注脑含水量和梗塞范围、脑卒中指数和脑组织中乳酸、乳酸脱氢酶、过氧化脂质、谷胱甘肽过氧化物酶、Na+-K+-ATP酶的影响。

objective:to evaluate the clinical effectiveness of titanium plate osteosynthesis in maxillofacial fractures.methods:216 maxillofacial fractures in 157 cases from 1998 to 2005 were treated with titanium microplate or miniplate osteosynthesis,122 of which were mandibular fractures and 94 of maxillary fractures.43 cases of maxillofacial fractures including cranial injuries in 157 cases and 38 cases including zygoma and zygomatic arch fractures and 13 cases including other injuries.results:most of the cases were healed.only 9 cases had complications.conclusion:the titanium plate osteosynthesis would bring about good effects.it would reduce facial malformation and regain normal occlusion after operations.
