A triple aorto-coronary vein bypass was performed in a 56-year-old Jehovah's Witness. Neither donor blood, albumin nor artificial macromolecules were used. Ten litres of non-haemic fluid were given during surgery and an additional 4 litres during the first 18 postoperative hours. During perfusion the haematocrit fell to 19 vol% and total protein in serum to 29 g/l. Eighteen hours after surgery, the patient was extubated without any signs of oedema and with a positive water balance of only 2.2 l. Diuretics were not given. Acid-base and electrolyte values were within normal limits both during and after operation. This and similar cases reported in the literature show that during extracorporeal circulation it is possible to reduce the concentrations of red cells and plasma proteins to below 40% of pre-operative values without serious complications.
一位56岁的耶和华见证会信徒接受了一次三支冠状动脉搭桥手术。术中未使用供血、白蛋白或人工大分子物质。手术期间输入了10升无血液体，术后最初18小时又额外输入了4升。灌注期间，血细胞比容降至19%（容积），血清总蛋白降至29g/L。术后18小时，患者拔除气管插管，无任何水肿迹象，正水平衡仅为2.2升。未使用利尿剂。手术期间及术后酸碱和电解质值均在正常范围内。本病例及文献中报道的类似病例表明，在体外循环期间，有可能将红细胞和血浆蛋白浓度降至术前值的40%以下而无严重并发症。
