先天性心脏病(congenital heart disease，CHD)术后重症监护的重要职责之一是维持血流动力学稳定以保证足够的组织氧供。目前，直接脉搏轮廓记录分析法(pressure recording analytical method，PRAM)作为新的微创血流动力学监测手段逐渐应用于婴幼儿CHD的围手术期，相比于其他血流动力学监测手段具有操作简单、创伤小、持续监测、准确性高的独特优势。本文将PRAM与其他血流动力学监测技术进行比较，阐述了PRAM的重要指标及应用前景，希望为婴幼儿CHD的术后监护提供指导。“,”One important responsibility of intensive postoperative care for congenital heart disease (CHD) is maintaining hemodynamic stability to ensure adequate tissue oxygen supply. At present, pressure recording analytical method (PRAM), as a new mini-invasive hemodynamic monitoring method, is gradually applied for infantile CHD during perioperative period. As compared with other hemodynamic monitoring methods, PRAM offers unique advantages of simpler handling, minimal trauma, continuous monitoring and greater accuracy. Here important parameters and application prospects of PRAM were discussed for providing guidance for postoperative cares of infantile CHD.
