摘要
目的观察超小剂量米非司酮配伍米索前列醇终止超早期妊娠(停经≤5周,血β—hCG水平高于正常、超声检查未见胎囊)的临床疗效。方法选取2011年5月至2012年3月月经周期规律、停经≤5周的早孕期妇女,依停经天数、血β—hCG水平和B超检查确定为超早期妊娠后分组,超小剂量组100例,米非司酮50mg两日法+48h后口服米索前列醇200μg;常规剂量组100例,米非司酮150mg两日法+48h后米索前列醇600如顿服;均在米索前列醇服后留院观察6h。定期随诊并记录观察日志,观察治疗结局并进行满意度白评。结果(1)孕囊排出:超小剂量组、常规剂量组妇女服药后可见孕囊排出分别为22例(22.0%,22/100)和25例(25.0%,25/100),两组比较,差异无统计学意义(P〉0.05)。(2)治疗失败:超小剂量组、常规剂量组不全流产者分别为1例(1.0%,1/100)和2例(2.O%,2/100),可疑异位妊娠者均为1例(1.0%),两组分别比较,差异均无统计学意义(P〉0.05)。(3)阴道出血:超小剂量组、常规剂量组妇女服用米非司酮期间开始阴道出血者分别为71例(71.O%,71/100)和78例(78.0%,78/100),两组比较,差异无统计学意义(P〉0.05);平均出血天数为(5.3±1.4)、(6.0±1.5)d,两组比较,差异有统计学意义(P〈0.01)。(4)副作用:超小剂量组头晕、头痛、恶心、呕吐、腹痛、腹泻的发生率分别为2.0%(2/100)、0、7.0%(7/100)、1.O%(1/100)、20.0%(20/100)、1.0%(1/100),均较常规剂量组低(P〈0.01),且以轻度恶心、轻度腹痛为主。(5)月经恢复情况:超小剂量组、常规剂量组月经如期恢复者分别为99例(99.0%,99/100)、98例(98.0%,98/100),推迟〉7d者分别为1例(1.0%,1/100)、2例(2.O%,2/100)。(6)满意度:两组满意度均为99.O%(99/100)。结论超小剂量米非司酮配伍米索前列醇终止超早期妊娠是安全、有效的方法,疗效与常规剂量相当,副作用明显减轻。
Objective To explore the lowest effective dosage of mifepristone combined with misoprostol in terminating ultra-early pregnancy. Methods All the cases of ultra-early pregnancy classified by amenorrhea days, β-hCG and vaginal B-ultrasonic were randomly divided into two groups. One hundred cases in G1 group ( minimized dosage) were orally administered 25 mg mifepristone once a day for 2 days and combined with 200 μg misoprostol 48 hours later, while 150 mg mifepristone combined with 600 μg misoprostol 48 hours later were given to 100 cases in G2 group ( normal dosage). All cases were observed for 6 hours after taking misoprostol and returned for assessment three days later. Results None missing. Expulsion of eonceptus : G1 and G2 group were 22 ( 22. 0% , 22/100 ) and 25 ( 25.0% , 25/100 ; P 〉0. 05). Failure rate:cases with incomplete abortion were 1 ( 1.0% , 1/100) and 2 (2. 0% , 2/100) in GI and G2 group, hospitalization for suspected eetopic pregnancies both was 1 (1.0%). Bleeding:bleeding cases during the administration of mifepristone in G1 and G2 group were 71 (71.0% , 71/100) and 78 (78.0%, 78/100; P〉0.05); the mean bleeding time were (5.3 ±1.4) days and (6.0±1.5) days (P〈0. 01). Other side effects: in G1 group, majority showed light nausea (7.0%, 7/100) and light abdominal pain (20. 0% , 20/100). Menses recovery:99 (99.0% , 99/100) for G1 group and 98 (98.0% , 98/100) for G2 group to recovery on scheduled time. Satisfactions:both were 99 (99. 0%, 99/100). Except mean bleeding days and side-effects, the differences above showed no significance ( P 〉 0.05 ). Conclusion It is safe and effective treatment with the lowest dosages of mifepristone and misoprostol to terminate ultra- early pregnancies.
