将136例拟行冠状动脉内光学相干断层成像(OCT)检查的患者,根据术中使用的灌注液随机分为生理盐水组和乳酸林格液组,比较两组术中心电图、肌钙蛋白等变化及成像质量.结果显示,乳酸林格液组恶性心律失常的发生率、肌钙蛋白升高比率较生理盐水组明显下降(分别为11.9％比1.4％,10.1％比22.4％,均P＜0.01)；两组OCT成像质量无明显差异.提示,OCT检查时用乳酸林格液代替生理盐水进行灌注,能较好保护缺血心肌,降低并发症.

The examinations of optical coherence tomography (OCT) images were obtained in 136 patients. Lactated Ringer's solution or physiological saline was used randomly as perfusate. Their electrocardiogram and cardiac enzymes were acquired to compare the safety and image quality of two perfusates.The incidence of ventricular arrhythmia and rise of cardiac enzymes were lower in the lactated Ringer's solution group than those in the physiological saline group.Yet the image quality of OCT had no difference.The use of lactated Ringer's solution as perfusate instead of physiological saline in OCT examination may protect the ischemic myocardium and reduce the incidence of complications.
