目的 研究益母草注射液聯(lián)合縮宮素對(duì)剖宮產(chǎn)產(chǎn)后出血的預(yù)防效果。方法 選擇2015年1月-2016年6月樂(lè)山市婦幼保健院采取剖宮產(chǎn)分娩的產(chǎn)婦500例，隨機(jī)分為兩組，對(duì)照組僅單純給予縮宮素，觀察組聯(lián)合給予縮宮素和益母草注射液。觀察兩組臨床療效、圍手術(shù)期指標(biāo)、術(shù)前和術(shù)后24 h血紅蛋白、紅細(xì)胞，記錄兩組不良反應(yīng)的發(fā)生情況。結(jié)果 觀察組的總有效率為90.40%（226/250），明顯高于對(duì)照組的73.20%（183/250），差異有統(tǒng)計(jì)學(xué)意義（P<0.05）。與對(duì)照組相比，觀察組的術(shù)中出血量、術(shù)后2h及24 h出血量明顯減少，差異有統(tǒng)計(jì)學(xué)意義（P<0.05）。觀察組的產(chǎn)后出血持續(xù)時(shí)間為（38.35±5.42）h，住院時(shí)間為（6.25±2.38）d，均明顯短于對(duì)照組，差異有統(tǒng)計(jì)學(xué)意義（P<0.05）。觀察組術(shù)后24 h血紅蛋白、紅細(xì)胞下降程度均明顯低于對(duì)照組，差異有統(tǒng)計(jì)學(xué)意義（P<0.05）。結(jié)論 益母草注射液聯(lián)合縮宮素可有效預(yù)防剖宮產(chǎn)產(chǎn)后出血，減少術(shù)后出血量并縮短止血時(shí)間，安全有效。

Objective To investigate the clinical effect of Yimucao Injection combined with oxytocin in preventing postpartum hemorrhage after cesarean section. Methods 500 cases of pregnant women with cesarean section who were treated in Leshan Maternal and Child Health Hospital from January 2011 to June 2016 weredivided into two groups randomly. The patients in the control group wereonly given oxytocin, while the patients in the observation group were given Yimucao Injection combined with oxytocin. To observe the clinical effect of the two groups, the amount of intraoperative hemorrhage volume, postoperative 2h bleeding, postoperative 24h bleeding volume, the duration time of postpartum hemorrhage and hospitalization time, and the occurrence of adverse reactions in the two groups. Results The total effective rate of observation group was 90.40%(226/250), which was significantly higher than the control group 73.20(183/250) (P<0.05).Compared with the control group, the amounts of blood loss, 2h postoperative bleeding volume and 24h postoperative bleeding volum in observation group were significantly decreased (P<0.05).The duration time of postpartum hemorrhage and hospitalization time in observation group were significantly shorter than the control group (P<0.05). 24 h hemoglobin and red blood cell of the observation group were significantly lower than that of the control group (P<0.05).The incidence of adverse reactions was significantly lower than that of the control group (P<0.05). Conclusion Yimucao Injection combined with oxytocin can effectively reduce the amount of bleeding, shorten the time of bleeding and hospitalization time, safe and effective, which is worthy of clinical application.
