简介:摘要目的分析探讨宫缩乏力产后出血产妇给予无创性护理的方法和效果。方法选取2011年1月~2016年1月我院妇产科收治的98例宫缩乏力性产后出血患者作为研究对象。随机分为观察组49例和对照组49例,对照组给予常规产后出血治疗及护理措施,观察组患者在此基础上给予无创性护理。对比分析两组患者止血时间、出血量以及产妇宫缩情况。结果对照组患者平均止血时间为64.7±3.9min,平均出血量为684.1±25.4ml,患者2h后宫缩恢复正常29人,恢复率59.1%。观察组患者平均止血时间为38.4±8.7min,平均出血量为526.4±61.2ml,患者2h后宫缩恢复正常39人,恢复率79.5%,两组患者对比具有统计学差异(P<0.05)。结论无创性护理针对宫缩乏力产后出血产妇,能有效的改善产妇宫缩情况,降低产妇出血量,提高产妇止血时间,且能有效的促进患者宫腔内淤血的排除,保证产妇的生命安全和健康,适合在临床上广泛推广和使用。
