对110例早孕妇女人工流产术前、术时和术后的宫腔内压(IUP)进行测定,其中33例在B超监视下手术。结果表明;①正常早孕妇女(孕6～12周)的IUP平均为2.19±0.85kPa(95％可信限:2.03,2.22kPa),早孕妇女的IUP记录曲线呈低幅度波形;②术时IUP为正压,术时和术后IUP变化幅度及频率均较术前明显增高,术时负压较高时IUP随之升高;③术时宫腔血液逆流发生率为33.33％,术时IUP较高组血液逆流发生率较高,揭示术时较高负压手术可能是导致子宫内膜异位症的一种高危因素。
110 cases of early pregnancy women induced abortion preoperative, postoperative and postoperative intrauterine pressure (IUP) were measured, of which 33 cases under B-ultrasound surgery. The results showed that: (1) The average IUP of normal pregnant women (6 to 12 weeks’ gestation) was 2.19 ± 0.85kPa (95% confidence limits: 2.03,2.22kPa) For positive pressure, intraoperative and postoperative IUP amplitude and frequency were significantly higher than preoperative, intraoperative elevated IUP with higher negative pressure; ③ intrauterine uterine bloodstream reflux rate was 33.33%, intraoperative IUP Higher rates of bloodstream reflux were higher, revealing that surgery at higher negative pressure may be a risk factor for endometriosis.
