研究目的:

评估在反复种植失败患者冻融胚胎移植患者中行宫腔灌注富血小板血浆(PRP)的疗效与安全性。  

Objectives of Study:

To evaluate the efficacy and safety of intrauterine perfusion of platelet-rich plasma (PRP) in patients with recurrent implantation failure and in patients with frozen-thawed embryo transfer.

药物成份或治疗方案详述:

1.激活剂配制:用4毫升生理盐水溶解凝血酶冻干粉,充分混匀,制成凝血酶激活剂; 2.将人工授精管(无菌导管或胚胎移植管)经宫颈,顺子宫曲度插入宫腔,当触及宫底时测量宫腔深度,调整导管尖距宫底 0.5cm; 3.将PRP和激活剂通过三通连接无菌导管,在无阻力下缓慢注入宫腔,待注射完毕时,抽吸少量空气将导管中剩余的PRP全部推入宫腔,卧床休息10-15 min。 4.内膜准备方案:所有患者均采用人工周期准备子宫内膜,待内膜厚度≥8mm时,肌注黄体酮转化内膜进行移植前准备。 

Description for medicine or protocol of treatment in detail:

1. Activator preparation: dissolve thrombin freeze-dried powder with 4 ml of normal saline, mix well to make thrombin activator; 2. Insert the artificial insemination tube (sterile catheter or embryo transfer tube) through the cervix and along the uterine curvature into the uterine cavity, measure the depth of the uterine cavity when it touches the fundus, and adjust the catheter tip to the fundus by 0.5cm; 3.Connect the PRP and activator to the sterile catheter through a tee, slowly inject it into the uterine cavity without resistance, and when the injection is completed, suction a small amount of air to push all the remaining PRP in the catheter into the uterine cavity, and rest in bed for 10-15 minutes. 4.Endometrial preparation plan: All patients use artificial cycles to prepare the endometrium, and when the endometrial thickness ≥ 8mm, intramuscular injection of progesterone to convert the endometrium for pre-transplantation preparation.

Exclusion criteria:

1. Untreated intrauterine lesions (such as polyps, submucosal fibromas, adhesions); 2.Known thrombophilia, hematological disease, or platelet dysfunction; 3.Autoimmune diseases, severe systemic diseases or uncontrolled endocrine diseases; 4.Received platelet-rich plasma (PRP) or other experimental intrauterine perfusion interventions in the past month; 5.Allergy to PRP preparation ingredients; 6.Participating in other interventional clinical trials at the same time.
