库存红细胞清洗在新生儿及小婴儿体外循环手术中的应用

Objective Priming blood in cardiopulmonary circuit is necessary for neonates and small infants. However, high concentration of potassium and lactate in pecked red blood cells transfused during cardiopulmonary bypass may have detrimental effects on meonstea and infants undergoing cardiac surgery. This study is to cornice the effects of trasfusing washed end unwashed peeked red blood cells for cardiopulmonary circuit on serum potassium and lactate concentrations preoperatively. Methods 30 neonates and small infants with complex congenitai heart disease undergoing open heart surgery were divided into 2 groups randomly. Unwashed group (n = 15) received unwashed pecked red blood cells and washed group (n=15) received packed red blood cells washed in a cell saver (Medtronic Autolog). Potasium and lactate concertrations were compared before, during and after bypass. Resuils Wash-packed red blood cells reduced donor blood K+] from (19.3±0.9)mmd/L to (1.1 +0.3) mmol/L, and lactate from 15 mmo/L to (7.8±1.2) mmol/L (P<0.001). The K+]in the prime solution was significantly higher (9.0±0.5) mmol/L vs. (2.6±0.1) mmol/L, P<0.001] in umwashed group than that of washed group, so did the lactate (9.5±2.6) mmol/L vs. (4.7±1.1) mmol/L, P
