简介: 【摘要】 目的:探讨凶险性前置胎盘产后大出血患者子宫切除术的最佳时机。方法:选取笔者所在科室 2018年 3月 -2019年 3月收治的 90例凶险性前置胎盘产后大出血患者,按照手术时机的不同分为观察组 28例和对照组 62例。对照组在剖宫产后立即切除子宫,观察组经保守治疗无效后行子宫切除术。比较两组手术出血量、输血情况及术后恢复情况。结果:观察组切除术前出血量、总出血量均多于对照组,新鲜冰冻血浆输注量多于对照组,差异有统计学意义( P<0.05)。两组的血细胞悬液输注量、全血输注量及凝血酶原复合物输注量比较差异无统计学意义( P>0.05)。两组术后抗生素使用时间、术后下床活动时间、住院时间、并发症发生率比较,差异均无统计学意义( P>0.05)。结论:凶险性前置胎盘产后大出血可经保守治疗无效后再行子宫切除,其不会增加患者的风险,还有可能为患者保留生育功能。 【关键词】 凶险性前置胎盘; 产后大出血; 子宫切除; 手术时机 [Abstract] Objective: To explore the best opportunity of hysterectomy in the patients with severe placenta previa and postpartum hemorrhage. Methods: 90 cases of PPH in our department from March 2018 to March 2019 were divided into observation group (28 cases) and control group (62 cases). The control group underwent hysterectomy immediately after cesarean section, and the observation group underwent hysterectomy after conservative treatment. The bleeding volume, blood transfusion and postoperative recovery were compared between the two groups. Results: the bleeding volume and total bleeding volume of the observation group before resection were more than those of the control group, and the fresh frozen plasma transfusion volume was more than that of the control group, the difference was statistically significant (P < 0.05). There was no significant difference between the two groups (P > 0.05). There was no significant difference between the two groups in the time of using antibiotics, the time of getting out of bed, the time of hospitalization and the incidence of complications (P > 0.05). Conclusion: hysterectomy can be performed after conservative treatment for severe placenta previa postpartum hemorrhage, which will not increase the risk of the patients, and may also preserve the fertility of the patients.
简介:摘要目的探讨颅内动脉瘤早期破裂出血显微夹闭术的最佳手术时机及疗效。方法回顾性分析2014年1月—2017年12月我院88例行显微夹闭术颅内动脉瘤破裂出血患者的临床资料,其中发病-手术时间≤24h的42例患者作为研究组,发病手术时间24h~72h的46例患者作为对照组。观察对比两组术中情况与临床疗效。结果两组手术时间、出血量与住院时间对比差异无统计学意义(P>0.05)。研究组预后良好率95.24%,高于对照组的78.26%,差异显著(P<0.05);研究组预后较差率2.38%低于对照组的17.39%,差异显著(P<0.05)。结论颅内动脉瘤破裂出血患者发病后≤24h是手术的最佳时机,可以有效提高预后效果,应尽快手术。
