人工流产手术中用Hegar扩张器快速扩张宫颈有时是困难的,偶尔还会给病人带来危险。因此,用海藻棒来扩张宫颈,这一古老的方法又重新受到重视。海藻棒是由一种海生植物的茎干燥后制成的,它具有很强的吸水性,受湿后其直径能逐渐增粗为原来的3～4倍。海藻棒能引起宫颈缓慢进行性扩张和软化,是一种无损伤的扩张宫颈的方法。用γ射线或环氧乙烷气体消毒海藻棒,可减少感染。本文报道了对48名健康早孕妇女(平均孕周为8.33)进行的对照研究。治疗组24例,吸宫术前5～7小时宫颈管插入海藻棒
The rapid expansion of the cervix with a Hegar dilator in abortion is sometimes difficult and occasionally dangerous to the patient. Therefore, the use of seaweed rods to expand the cervix, this ancient method has been re-valued. The seaweed stick is made from the dried stem of a marine plant that has a very strong water absorption that can be 3 to 4 times as thick as it gets wet. Seaweed sticks can cause the cervix to slowly expand and soften, a non-invasive method of expanding the cervix. Sterilize algae sticks with gamma rays or ethylene oxide gas to reduce infection. This article reports a controlled study of 48 healthy early pregnant women (mean gestational age: 8.33). The treatment group, 24 cases, 5 to 7 hours before the suction aspiration cervical canal into the seaweed rod
