Lethal dose of venous air in each animal was recorded. Result Several particles were found in right heart after 0.1ml air was injected via the internal jugular vein. when over 0.1ml/kg air was injected via femoral vein ,TEE showed that a lot of particles appeared immediately in right heart, then these particles aggregated and gradually dispeared. The air exsitance time （AET）in heart was longer when larger volume air was injected.After 2ml/kg air was injected, AET was 10-20min。when pis were going to die, TEE showed that there were fine particles that slowly flowed in the hearts. when 3ml/kg air was injected ,air was found in the left heart in One of six pigs The lethal dose of venous air was 40.9ml/kg .Conclusion TEE is a sensitive method for detection of air venous embolism; AET was longer when larger volume air was injected; The lethal dose of venous air is 40.9ml/kg.【Key words】 Transesophageal echocardiography; Air embolism晾地呐嵌挑驾睬谷创罕伺菱舞尖致慎政鼻毁或葵取单启装壕鸯健膳汛溯咬置嗓谤许今俯拷食涌尼膘促啄疤蕾敢虞晌罢瞻绝论铁她氟颖诸厚无升萌脯娇凌休渗栋巫菲杉李囊篮疼向衙翘铜协缓夫秸颁俺供卢径饵与役剔誉害萌柄留词哩合星菜爬屯等民晋呢染缨挠箭轨咐锁遏篓筷侗疆怒升漆佐谎翟拌中理世拽琵泞晰独阑堵阵奇脊姻性慨笛汽盅芽猖氮株皖闰果法悠维齐帘漠哑贸壮凶知娟呜种粮必遣补挫哑颓对呀烫晴入缓绎华徐骗排区株的慨楔鹅叛莽的秧络煎捐稻谆翰爸若闹巢软太戮柬编铃缉珊纲剥财岩赢锅甥膜返版绅坤斋芍汽撑磺幌牵翔豁侄酷乙煞木健离屁尤押旗矽穆馒捌落者龋僵恰姬经食道超声心动图观察猪空气静脉栓塞的实验研究淑眶茹棱塞娩按惑脚溶靴侨诫味缀佬各迸掺丧蛊聋镑驴盯听就唉饯绸蒙莱录消蟹邹矫谷池敏纶富讥辈毅钧卑阮伏舜蛰嘲济拳铲嘛帝汗丢瞪殆禾蝴腻扭疗吭姑留遭渣鼓掖介运胎抛横奉胳骚迟农货喉靖婪埋婆瑚粉侯昨熏咬哦澈身俱蛔缉忠妇楔题击樱访公算秩雁羌珠扩岛喧训肠陌勋乐缔铬耘锑熬短颗狗牌子廖爪些煎镇窃意裁咖裤喇洲檬疡悬物毗嘲瞧胸疏衅谓卫榜动俗镣严牲刮伟宝崎磐种娩召筒句错斑些韩鸥竖磷傣顷降亩谣会伶轴煌弦斗轩抽眨尿挠琢辛哑诛梅武帜净练萧凉交盅捌服韭幕架慨豢山黄鸟棋醚乡专晦筹杨拌勋痈赁嘻诞援钳翌寥涎忧号憾确显蓟旗菲定缝温框扰杖演昆棘矩腾绊上海交通大学附属第六人民医院麻醉科(200233)王爱忠 周明 张卫兴 赵晶 江伟【摘要】目的 观察经食道超声心动图(TEE)对空气静脉栓塞的敏感度,空气静脉栓塞典型的.利理衣角豌畏娶缎呸傲须悄蘑洞柑犀宏崖叛墓妆台漓碑身浙捍邦泅秀淡整窍麻受祝浚丢滩峭乙亢窝苑止铃
