Intermittent cross clamping with Lidoflazine has proven to deliver good cardioprotection in our center. Question: Is tepid (32°C) antegrade intermittent blood cardioplegia an efficient, safe and easy-to-use alternative to intermittent cross-clamping with Lidoflazine in elective isolated CABG in low-risk patients? Primary outcomes are heart enzymes (cTnI, CK-MB). Secondary outcomes are operation times, length of hospital stay, major complications and in-hospital mortality. Methods: From January 2012 until November 2012, 40 patients with LVEF ≥50%, EuroSCORE展开更多

Tissue samples were taken from the right atrium before weaning from CPB and from the right appendage 30 minutes after removal of the cross-clamp. The results of pathological study in these two groups were as follows: the structural alterations were most severe during the ischemic period in the hypothermic group. Damages of the myocardial展开更多
目的比较五种心脏停搏液对心脏直视手术的未成熟心肌保护效果。方法随机将180例非紫绀型先天性心脏病患儿分成5组:HTK液组(A组)、改良St·Thomas液组(B组)、4∶1(自体血∶晶体)含自体血冷心脏停搏液组(C组)、1∶1(自体血∶晶体)含...目的比较五种心脏停搏液对心脏直视手术的未成熟心肌保护效果。方法随机将180例非紫绀型先天性心脏病患儿分成5组:HTK液组(A组)、改良St·Thomas液组(B组)、4∶1(自体血∶晶体)含自体血冷心脏停搏液组(C组)、1∶1(自体血∶晶体)含自体血冷心脏停搏液组(D组)和1∶4(自体血∶晶体)含自体血冷心脏停搏液组(E组)。五组患儿平均年龄(5.8±0.4)月,平均体重(6.1±0.3)kg。体外循环时间42~105(68.2±5.3)min,主动脉阻断21~68(38.4±4.6)min。对比分析体外循环前1 h及术后6 h、12 h及48 h肌钙蛋白I(cTnI)和磷酸肌酸酶同工酶(CKMB);术前及术后1 h、6 h左室射血分数(LVEF)。结果各组患儿体外循环前1 h及术后48 h cTnI及CKMB无显著性差异,术前及术后6 h LVEF均无统计学差异(P>0.05);HTK液组及1∶4含自体血冷心脏停搏液组术后6 h及12 h cTnI及CKMB较其他三组低,存在显著差异(P<0.05);HTK液组及1∶4含自体血冷心脏停搏液组术后1 h LVEF较其他三组高,存在显著差异(P<0.05)。结论 HTK液、1∶4含自体血冷心脏停搏液对未成熟心肌心肌保护作用较好。展开更多
