我院采用B超耻联下横向扫查法,对150例晚期妊娠孕妇坐骨棘间径(ISD)进行测量,并与临床测量的出口横径(TO)进行对比,探讨本方法的可行性。 1 临床资料本组150例晚期妊娠孕妇系我院1990年12月至1991年4月门诊或部分住院孕妇,均为初产妇,年龄20～31岁,孕周28～42周,使用Aloka—610型实时超声诊断仪,探头频率3.5mHz。 1.1 ISD的测量:置探头于耻联下约1cm处,行横向扫查,探头与探查部位垂直或稍向足方倾斜,借助耻骨弓为声窗,以充分显示两侧坐骨八字型回声为标准,上下侧动声束方向,在坐骨八字型回声两侧末端寻找坐骨棘
In our hospital, B-Shametry combined with lateral scanning method was used to measure the ISD of 150 pregnant women with advanced pregnancy, and compared with the clinically measured exit diameter (TO) to explore the feasibility of this method. 1 clinical data of 150 pregnant women in this group of late pregnancy in our hospital from December 1990 to April 1991 outpatient or part of hospitalized pregnant women, all primipara, aged 20 to 31 years, gestational age 28 to 42 weeks, the use of Aloka-610 Real-time ultrasonic diagnostic apparatus, probe frequency 3.5mHz. 1.1 ISD measurement: set the probe at about 1cm under the shameless line, horizontal scan, the probe and the probe site vertical or slightly to the foot tilt, with the sound of the pubic arch for the window to fully display both sides of the sciatic bullhead echo as the standard , The sound beam direction of the upper and lower side of the sciatic octagonal echo at the ends of the search for ischial spines
