Thirty primigravidae referred for termination of pregnancy in the first trimester participated in a prospective randomised investigation. The object of this investigation was to determine the extent of cervical dilatation obtainable employing a new osmotic cervical dilator, Lamicel. In fifteen patients, a 3 mm Lamicel rod was introduced four hours prior to abortion by suction and fifteen patients functioned as the control group. In the treated group, dilatation of the cervix was commenced with a cervical diameter of 7 mm compared with 3 mm in the control group (p less than 0.01). Four patients stated that they experienced transient pain on introduction of Lamicel. No differences in the nature and frequencies of complications were observed between the groups. Employment of Lamicel provides gentle and effective dilatation of the cervical canal and the method is thus considered as suitable for termination of pregnancy.
30名孕早期前来进行人工流产的初产妇参与了一项前瞻性随机研究。该研究的目的是确定使用一种新型渗透性宫颈扩张器Lamicel所能达到的宫颈扩张程度。15名患者在负压吸引流产前4小时插入一根3毫米的Lamicel棒，另外15名患者作为对照组。在治疗组中，宫颈扩张始于宫颈直径为7毫米时，而对照组为3毫米（p<0.01）。4名患者表示在插入Lamicel时经历了短暂疼痛。两组之间在并发症的性质和发生率上未观察到差异。使用Lamicel可使宫颈管得到轻柔而有效的扩张，因此该方法被认为适用于人工流产。
