摘要
目的评估托马斯心肌保护液(St.Thomas液)与康斯特心肌保护液(HTK液)在冠状动脉异常起源于肺动脉(anomalous origin of coronary artery from pulmonary artery,ACAPA)患儿心脏外科手术中的心肌保护效果。方法回顾性分析2011年5月至2015年4月外科手术治疗44例ACAPA患儿临床资料,根据心肌保护采用不同晶体停跳液分为St.Thomas液组(24例)与HTK液组(20例)。两组患儿术前一般情况比较,差异均无统计学意义(P〉0.05)。比较患儿术中及术后1个月左心室射血分数(1eft ventricular ejection fraction,LVEF),体外循环时间,升主动脉阻断时间,气管插管时间,晶体停跳液使用量,儿科重症监护室停留时间,术后儿科重症监护室正性肌力药物使用时间及体外膜肺氧合(extracorporeal membrane oxygenation,ECMO)支持情况。结果St.Thomas液组术中食道超声及术后1个月经胸超声测定LVEF值分别为(43.03±18.74)%和(49.83±17.93)%,HTK液组分别为(44.36±17.12)%和(53.95±15.44)%,组间比较,差异均无统计学意义(P〉0.05)。St.Thomas液组、儿科重症监护室停留时间、气管插管时间及多巴胺、多巴酚丁胺、肾上腺素使用时间分别为(153.50±196.62)h、(70.84±127.28)h、(138.56±174.98)h、(118.41±155.24)h和(44.06±73.74)h,HTK液组分别为(129.06±159.89)h、(67.04±121.56)h、(147.24±164.05)h、(121.00±162.66)h和(34.44±62.62)h,组间比较,差异均无统计学意义(P〉0.05)。St.Thomas液组有2例患儿接受ECMO辅助,HTK液组有1例,均顺利撤除。结论在本组患儿中,St.Thomas液与HTK液2种晶体停跳液对ACAPA外科手术矫治中的心肌保护效果未见明显差异。ECMO是此类手术的重要保障。
Objective To evaluate the outcomes of myocardial protection for two different solutions of crystal cardioplegia during cardiac operations in children with anomalous origin of coronary artery (ACAPA). Methods Retrospective reviews were conducted for 44 children undergoing surgery for ACAPA from May 2011 to April 2015. They were divided into 2 groups of St. Thomas (ST, n = 24) and HTK (n = 20). The average mechanical ventilatory time, average pediatric intensive care unit (PICU) time, average inotropic dosing time, left ventricle ejection fraction (LVEF) during and 1 month post-operation, ECC time, aortic clamping time and cardioplegia volume were collected. Results All children underwent coronary artery root transplantation. The average mechanical ventilation time of ST and HTK groups were (70. 84±127. 28)h, (67. 04 ± 121.56)h (P = 0. 920), average PICU time (153.50 ± 196. 62) h, (129. 06 ±159. 89) h(P = 0. 658), average dopamine, dobutamine adrenaline time (138. 56± 174. 98)h, (147. 24 ±164. 05)h(P = 0. 867) ; (118. 41 ±155.24)h, (121.00 ± 162. 66)h (P= 0. 867) ; (44. 06 ±73. 74)h, (34. 44 ±62. 62)h (P = 0. 647), LVEF during and 1 month post-operation (43. 03 ±18. 74) %, (44. 36 ± 17. 12) % (P = 0. 855) ; (49. 83± 17. 93) %, (53.95±15.44)% (P = 0. 428). None of inter-group differences were statistically significant. Two children in ST group and one child in HTK group received extracorporeal membrane oxygenation (ECMO). All children weaned off ECMO successfully. Conclusions No significant difference exists in myocardium protection for two solutions of crystal cardioplegia. And ECMO plays vital roles during operations.
