[摘 要] 目的:探讨del Nido 停搏液和组氨酸⁃色氨酸⁃酮戊二酸(histidine⁃tryptophan⁃ketoglutarate,HTK)停搏液在左心室肥
厚(left ventricular hypertrophy,LVH)患者行心内直视手术中的临床应用效果。方法:回顾性收集2021年1月—2022年12月在
南京医科大学第一附属医院心脏大血管外科进行心脏体外循环手术的LVH患者75例,根据术中使用停搏液类型分为del Nido
组(D组,39例)和HTK组(H组,36例)。比较两组患者一般资料、手术麻醉与体外循环资料、术后临床资料及围术期心肌标志
物改变等。结果:升主动脉开放后,D组室颤发生率低于H组(P < 0.01)。发生室颤患者中,D组的室颤持续时间、除颤次数和
除颤能量均低于H组(P < 0.05)。D组复跳时间长于H组(P < 0.05),D组临时起搏器使用率高于H组(P < 0.05)。体外循环结
束后15 min,D组血管活性药评分(vasoactive⁃inotropic score,VIS)高于H组(P < 0.001);而手术结束前15 min以及术后6 h两组
VIS评分比较,差异无统计学意义(P > 0.05)。在心肌标志物方面,仅发现术后24 h,H组肌酸激酶同工酶(creatine kinase⁃MB,
CK⁃MB)和肌钙蛋白 T(cardiac troponin T,cTnT)高于 D 组(P < 0.05);两组术后 48 h 心肌标志物比较,差异无统计学意义(P >
0.05)。结论:del Nido停搏液和HTK停搏液均可安全用于LVH患者术中心肌保护,但使用HTK停搏液,主动脉开放后室颤发
生率更高,术后24 h CK⁃MB及cTnT高于del Nido停搏液;而使用del Nido停搏液,心脏复跳时间更长,临时起搏器使用率更高,
且停机后15 min时的血管活性药使用量高于HTK停搏液。

[Abstract] Objective:To explore the clinical application effects of del Nido and histidine ⁃ tryptophan ⁃ ketoglutarate(HTK)
cardioplegia in patients with left ventricular hypertrophy(LVH)undergoing open⁃heart surgery. Methods:A total of 75 LVH patients
who underwent cardiopulmonary bypass(CPB)surgery in our hospital from January 2021 to December 2022 were retrospectively
collected and were divided into del Nido group(group D,39 cases)and HTK group(group H,36 cases)according to the type of
cardioplegia used during open ⁃ heart surgery. General information,interoperative anesthesia and cardiopulmonary bypass data,
postoperative clinical information,and changes in perioperative myocardial markers were compared between the two groups. Results:
After releasing aortic cross⁃clamp(ACC),the incidence of ventricular fibrillation(VF)was lower in the group D than in the group H
(P < 0.01). Among patients with VF,the duration of VF,defibrillation times,and defibrillation energy were lower in the group D than
in the group H(P < 0.05). The group D had a longer time for spontaneous heart rhythm recovery than the group H(P < 0.05),and the
temporary pacemaker usage rate was higher in the group D than in the group H(P < 0.05).The group D had a higher vasoactive⁃
inotropic score(VIS)score 15 minutes after the end of CPB than the group H(P < 0.001),while there was no significant difference in
