We developed a new method to monitor left atrial pressure in the patients undergoing open heart surgery. The advantages of our method are 1) freedom from complications relating its removal (eg. bleeding) because of its transvenous insertion, and 2) simultaneous monitoring of both right and left atrial pressures by a single catheter. We designed to place the second port of a two-lumen central venous catheter 5 or 7 cm proximal to the tip. The catheter is inserted into the right atrium before surgery and the tip is advanced in the left atrium through the foramen ovale intraoperatively. We used this catheter in 16 infants and children, and found that effective hemodynamic monitoring was obtained without any complications. We recommend this method for the postoperative management of open heart surgery in the pediatric patients.
我们开发了一种新方法来监测接受心脏直视手术患者的左心房压力。我们方法的优点是：1）由于经静脉插入，不存在与移除相关的并发症（如出血）；2）通过单个导管可同时监测右心房和左心房压力。我们设计将双腔中心静脉导管的第二个端口置于距尖端近端5或7厘米处。在手术前将导管插入右心房，术中通过卵圆孔将尖端推进至左心房。我们在16例婴幼儿中使用了该导管，发现能有效进行血流动力学监测且无任何并发症。我们推荐这种方法用于小儿心脏直视手术的术后管理。
