胎儿常有较高的红细胞比积(HC),但其出生时中心静脉血HC若>65%,则应视为异常。本文对本病患儿作部分血浆换血(简称换血)治疗的指征,以及换血对患儿全血细胞计数(CBC)、血小板计数及凝血象的影响作了探讨。研究对象为42例生后4小时内毛细血管血HC≥70%者;其中32例符合换血的指征(周围静脉血HC≥70%;或HC>65%,但同时有下述征象中2个以上者:面色深红、发绀、易激惹、惊厥、嗜睡、呼吸困难、心动过缓或过速等)。这32例中20例作了CBC与凝血象,其中10例还在换血前复查了CBC。对照组则
Fetal often higher hematocrit (HC), but when the birth of central venous blood HC if> 65%, it should be considered abnormal. This article in children with partial replacement of plasma exchange of blood (referred to as transfusion) indications, as well as exchange of blood on children with complete blood count (CBC), platelet count and coagulation phenomenon were discussed. Forty-two patients with HC≥70% of capillary blood within 4 hours after birth were enrolled in this study. Among them, 32 patients met the criteria of blood transfusion (HC≥70% in peripheral venous blood or HC> 65%), while 2 Or more: dark red complexion, cyanosis, irritability, convulsions, lethargy, dyspnea, bradycardia or over-speed, etc.). Twenty of the 32 patients underwent CBC and coagulation, of which 10 were also examined for CBC before transfusion. Control group then
