portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">1个单位的浓缩血小板约含2.0×10^10个血小板,一般来说,患者输入10单位浓缩血小板约可升高血小板计数为portant; word-wrap: break-word !important;">36×10^9/L,但实际升高的情况可因病情不同和个人体表面积不同而有差异。

portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">机采的血小板每袋(一个治疗量)应≥2.4×10^11个血小板,成人每次输注一袋,可升高血小板为portant; word-wrap: break-word !important;">40×10^9/L,但实际升高的情况可因病情不同和个人体表面积不同而有差异。

portant; word-wrap: break-word !important;">

portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">血小板输注的剂量取决于患者输血前血小板计数和预期要达到的血小板计数以及患者的临床情况等。第一次可输注portant; word-wrap: break-word !important;">2单位/10kg血小板,输注后根据血小板计数增加情况和临床情况决定以后输注计划。输入的血小板存活期为5天,故应2~3天输注一次,直至出血停止。

portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">从血库或输血科取来的血小板最好立即输注,输注速度宜快,以患者可以耐受为准。

portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">①portant; word-wrap: break-word !important;">血小板计数>100×10^9/L,可以不输。

portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">②portant; word-wrap: break-word !important;">血小板计数<50×10^9/L,应考虑输。

portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">③portant; word-wrap: break-word !important;">血小板计数在50~100×10^9/L之间,应根据是否有自发性出血或伤口渗血决定。

portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">④portant; word-wrap: break-word !important;">如术中出现不可控渗血,确定血小板功能低下,输血小板不受上述限制。

portant; word-wrap: break-word !important;">血小板输注注意事项

portant; word-wrap: break-word !important;">

portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">①portant; word-wrap: break-word !important;">输注前要轻轻摇动血袋使血小板悬起,切忌粗鲁摇动,以防血小板损伤。

portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">②portant; word-wrap: break-word !important;">血小板的功能随保存时间的延长而降低,血库取出的血小板应尽快输用。

portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">③portant; word-wrap: break-word !important;">用输血器以病人可以耐受的最快速度输入,以便迅速达到止血水平。

portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">④portant; word-wrap: break-word !important;">若因故(如病人正在高热)未能及时输用,若无血小板专用摇摆机,则应在常温下放置,每隔10分钟左右轻轻摇动血袋(防止血小板聚集),不能放入4℃冰箱暂存。

portant; word-wrap: break-word !important;">

portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">①portant; word-wrap: break-word !important;">病人产生了同种免疫,使输入的血小板迅速破坏。

portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">②portant; word-wrap: break-word !important;">病人有脾肿大伴脾功能亢进,使输入的血小板破坏增多。

portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">③portant; word-wrap: break-word !important;">病人有发热、感染、DIC和活动性出血等,使血小板损耗过多。

portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">④portant; word-wrap: break-word !important;">在血小板输注前3天,病人服了阿斯匹林类药物,损害了血小板功能。
