气栓

H. When a free flow of blood appears in the syringe, remove the syringe and occlude the needle with a finger to prevent air embolism.

当注射器回血通畅，稳住，保留针头、拔下注射器，并用手指遮蔽针头尾部以避免气体进入血管导致气栓。

In all patients, both left and right middle cerebral artery Doppler signal were acquired by automatic embolus dectections machine.

结果 微气栓进入脑血流的时间主要发生在主动脉阻断钳开放后3 min的时段。

RCP is regarded as an assistant method in deep hypothermic circulatory arrest in that it provides partial brain blood flow,maintains a low brain temperature,optimizes cerebral metabolic function during DHCA by supplying oxygen and some nutrient and removal of catabolic products;it also reduces the incidence of cerebral embolization by flushing out air and particulate microemboli from the arterial tree before the reinstitution of antegrade perfusion,thus prolonging the limitation of safety of DHCA.But brain edema probably happens to restrict the clinical use of this method.

上腔静脉逆行性灌注是深低温停循环脑保护的辅助手段，已证明在低温状态下，它为脑部提供低流量血流，维持脑部低温状态；提供部分氧和营养物质，运走代谢产物；减少气栓及栓塞的发生，从而延长了深低温停循环脑保护的安全时限，而脑水肿的危险性限制了该方法在临床的应用。

Thesame observer was able to terminate vapor lock in 10 of 10 trials.

同一操作者又在10次实验中完全成功地排出了气栓。

A blinded observer was ableto identify the onset of vapor lock in 10 of 10 trials.

操作者在盲视下定位气栓，10次实验均成功。

Model animal ; acute myocardial infarction ; gas embolism

动物模型；心肌梗死；气栓

Severe complication included 1 cases of pericardial tamponade, 1 case of cardiac arrest with ST elevation and 1 case of temporary cerebral gas embolism.

严重并发症包括1例术后心包压塞，1例一过性窦性停搏伴下壁导联ST段抬高，1例一过性脑气栓，无死亡病例。

A large blood volume could be obtained by abdominal aorta approach, which leads to less haemolysis and no hurt to organs, no gas embolism or haemostasis caused by inappropriate operation.

腹主动脉采血法适用于取血量大的实验，不易溶血，不损伤器官，不会出现因操作不当造成的气栓与瘀血，有利于病理组织学检查。

The causes of the difficulty of CR during open heart surgery with ECC are concerned with the cardiac diseases and other causes, including gas embolism, electrolyte disturbance and acid-base balance disturbance.

ECC心内直视手术中心脏复苏困难的原因与心脏本身病变、气栓、酸碱电解质失衡等因素有关。

Then animals were killed by gas embolism, aorta was separated from the beginning of aortic arch to abdominal aorta crotch. At the end of experiment, the aortas were prepared for measuration of the concentration of ceramide and cholesterol. The pathological changes and plaque area were measured.

第十周实验结束时，用气栓法处死动物，将主动脉全部取下，沿正中线剪开，摄像，同时作主动脉斑块面积分析及HE染色等主动脉病理学检测，并取血管组织用HPTLC测量血管胆固醇的含量。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
