冷血含钾停搏液在小儿心直视术中的应用

APPLICATION OF COLD BLOOD CARDIOPLEGIA TO OPEN HEART OPERATION ON CHILDREN

作者自１９９２年５月至１９９３年５月在３４例小儿重症先天性心脏病（先心病）心直视术中应用冷血含钾停搏液（ＢＣＰ）１６例，与应用冷晶体停搏液（ＣＣＰ）的１８例作对比，ＢＣＰ级取得满意的心肌保护效果。结果表明：ＢＣＰ组术后心肌同工酶（肌酸激酶，乳酸脱氢酶），门冬氨酸基转移酶的活力明显低于ＣＣＰ组，并且自动复跳率高（９３％），无脱机困难，术后所需血管活性药物支持少，无低心排和死亡。

From May 1992 to May 1993,34 children with severe congenital heart diseases underwent open heart operation.We used cold blood cardioplegia(BCP)for 16 patients,cold crystalloid cardioplegia(CCP)for 18 patients.The results indicated that :the postoperative cardiac isoenzyme of creatine kinase,lactate dehydrogenase and aspartate aminotransferase levels in the CCP group were higher than those in the BCP group.In the BCP group 93% of the patients resumed heart beat spontaneously,with less inotropic drug support,and no patient weaned difficultly from cardiopulmonary bypass. No low cardiac output syndrome or death was recorded.
