摘要
旨在观察飞行中胆囊结石有无位移及能否诱发空中突然失能。采用日本SDL－32型B超诊断仪，对16名飞行人员胆囊结石患者进行了地面及空中观察。结果表明，地面观察未见胆囊结石有明显位移；跟班飞行观察，从飞机爬升经巡航到下滑几个阶段内，胆囊结石保持原位不动者9例（共有块状结石7枚，泥沙状结石3堆），其中结石位于胆囊颈部3例、胆囊体部6例，为滞留型；结石发生了位移者7例（共有块状结石13枚），其中结石由胆囊颈部降到胆囊体部者4例、由胆囊体部落到胆囊底部者2例，在胆囊体部前后壁间横向移位者1例，为游移型。游移型结石有可能速入胆道，引起突然失能，危及飞行安全，应密切观察。
The purpose of this study was to explore if the gallstones moved in gallbladder duringnight. sixteen pilots with gallstones were examined on the ground and monitered in the air by ultrasono-graphic equipment of SDL-32 model. The results showed that no significant displacement of stones wasfound when examined on the ground. During flight,from climbing,cruise to descending, 9 out of 16 caseswere of detained type,their gallstones remained their original location, 3 cases with gallstones located atthe neck portion of gallbladder,6 cases in the body of gallbladder Ithe remaining 7 cases were of movabletype, in which gallstones moved from neck portion to body of gallbladder in 4 cases,gallstones frombody to fundus of gallbladder in 2 cases,gallstones showed anterior posterior displacement in 1 case. Itwas supposed that the movable gallstones might pass into biliary tract,and cause sudden incapacitatingof pilot,which would jeopadize the night security.
