Swan-Ganz catheters were used in the care of 3 toxemic parturients who developed pulmonary edema. Initial pulmonary capillary wedge pressures (PCWP) ranged from 22 to 33 torr, indicating decompensated left ventricular failure. Simultaneous central venous pressures were essentially normal. Isolated left ventricular dysfunction was primarily the result of increased afterload and responded to afterload reduction with arteriolar vasodilators. Continued measurement of PCWP permitted the titration of afterload reduction to the levels associated with normal ventricular filling pressures and volume. Since the relationship between right and left ventricular pressures may be disturbed in cardiogenic pulmonary edema, the Swan-Ganz catheter is the preferred method of hemodynamic monitoring in toxemic patients who develop cardiopulmonary dysfunction.
Swan-Ganz导管用于护理3名发生肺水肿的毒血症产妇。初始肺毛细血管楔压（PCWP）范围为22至33托，表明左心室功能失代偿。同时中心静脉压基本正常。孤立的左心室功能障碍主要是后负荷增加的结果，并对使用小动脉血管扩张剂降低后负荷有反应。持续测量PCWP可将后负荷降低滴定至与正常心室充盈压力和容量相关的水平。由于心源性肺水肿时左右心室压力之间的关系可能受到干扰，Swan-Ganz导管是发生心肺功能障碍的毒血症患者血流动力学监测的首选方法。
