心脏瓣膜置换术麻醉期间血管内脉图法与热稀释法测心输出量的比较

COMPARISION BETWEEN INTRAARTERIAL PULSEGRAPHY AND THERMODILUTION METHOD FOR DETERMINATION OF CADIAC OUTPUT DURING ANESTHESIA AND OPERATION IN PATIENTS UNDERGOING CARDIAC VILVE REPLACEMENT

在麻醉手术期间应用ＨＭＵ－Ⅱ型心功能仪血管内脉图法与Ｓｗａｎ－Ｇａｎｚ导管热稀释法同步测定了１４例心功能Ⅲ～Ⅳ级心脏瓣膜置换术患者的心输出量，并进行了比较。结果示：两者心输出量与心脏指数均呈中～高度正相关，术后仍呈中～高度正相关。提示：ＨＭＵ－Ⅱ型心功能仪血管内脉图法在瓣膜置换术中其测值未受影响，故认为此法适用于重症病人手术中心功能的连续监测。

Comparision of intraarterial pulsegraphy and standard thermodilution methods for determination of cardiac output (CO) in 14 patients with poor cardiac function following valve replacement operation was performed. The CO, cardia index (CI) were moderate to high correlated between the two methods before and after valve replacement respectively. The study indicates that intraarterial pulsegraphy provides a continous method of determining CO in patients with poor cardiac function during operation.
