PURPOSE
Bioelectrical impedance analysis (BIA) has been used recently to measure the body water of patients with acute heart failure. We used BIA in this study to better understand, and possibly identify a predictive marker for, perioperative water behavior in cardiac surgery patients.
METHODS
We measured body water and studied its behavior in 44 patients undergoing surgery for cardiac valvular disease at our hospital. Measurements included the levels of extracellular water (ECW), intracellular water (ICW), and total body water, the edema index (EI), and the ratio of ECW to total body water. The first measured EI was defined as the "preoperative EI" and the maximum as the "peak EI".
RESULTS
A negative correlation was found between the preoperative EI and the preoperative estimated glomerular filtration rate (eGFR) (R = 0.644, p < 0.001). Positive correlations were found between the peak EI and the ICU stay (R = 0.625, p < 0.001), the peak EI and the ventilation time (R = 0.366, p < 0.01), and the preoperative EI and the ICU stay (R = 0.464, p = 0.026).
CONCLUSION
The EI is possibly a predictive marker for perioperative water management in cardiac surgery.
目的
生物电阻抗分析（BIA）最近已被用于测量急性心力衰竭患者的体液。我们在这项研究中使用 BIA 来更好地了解和识别心脏手术患者围手术期水代谢的预测标志物。
方法
我们对在我院接受心脏瓣膜病手术的 44 例患者的体液进行了测量和研究。测量包括细胞外液（ECW）、细胞内液（ICW）和总体水、水肿指数（EI）以及 ECW 与总体水的比值。第一次测量的 EI 定义为“术前 EI”，最大值定义为“峰值 EI”。
结果
术前 EI 与术前估算肾小球滤过率（eGFR）呈负相关（R=0.644，p<0.001）。峰值 EI 与 ICU 停留时间（R=0.625，p<0.001）、峰值 EI 与通气时间（R=0.366，p<0.01）以及术前 EI 与 ICU 停留时间（R=0.464，p=0.026）呈正相关。
结论
EI 可能是心脏手术围手术期水管理的预测标志物。
