4.Two-day cervical preparation was found to produce greater cervical preparation than one-day, but had no impact on procedure time. Serious complication rates or ability to complete the procedure did not differ significantly between any of the preparation methods reviewed.
AUTHORS' CONCLUSIONS: Cervical preparation with osmotic dilators and/or misoprostol before second-trimester D&E is safe and effective. Osmotic dilators appear to provide superior cervical dilation when compared to prostaglandins alone or when combined with prostaglandins, however this difference in cervical dilation does not appear to result in differences in procedure time or complication rates. There does not appear to be clear clinical benefit from two days of cervical preparation compared to one-day prior to second-trimester D&E below 19 weeks gestational duration. Mifepristone plus misoprostol was associated with high rates of pre-procedural expulsions and does not appear to be a useful method of cervical preparation before second-trimester dilation and evacuation.

為期兩天的準備，發現子宮頸超過一天產生更大的子宮頸，但並沒有影響手術時間。嚴重併發症的發生率或能力完成該過程並沒有顯著差異的製備方法的任何審查。
回覆刪除作者的結論：子宮頸準備與滲透擴張器和/或米索前列醇在孕中期的D＆E是安全有效的。似乎滲透擴張器擴張提供頸上前列腺素相比，單獨或合併時，前列腺素，但這種差異在子宮頸擴張不會出現差異導致手術時間或並發症的發生率。似乎沒有被明確的臨床受益於兩天相比，子宮頸癌的準備為期一天前孕中期D及E低於妊娠19週的時間。米非司酮加米索前列醇與高利率的預程序驅逐並沒有出現是一個有用的方法頸椎前的準備工作孕中期擴張和疏散。
