经食管超声多普勒在部分肝切除术液体治疗中的应用

Transesophageal Doppler monitoring for fluid therapy in patients undergoing partial hepatectomy

目的研究经食管超声多普勒血液动力学监测对部分肝切除术中液体治疗的指导价值。方法将40例拟行部分肝切除术的患者随机均分为经食管超声多普勒组(D组)和中心静脉压(CVP)组(C组)。D组采用经食管超声多普勒进行血液动力学监测指导术中输液,C组采用CVP监测指导术中输液,观察两组患者输液量、血液动力学变化和液体治疗的效果。结果D组较C组患者血液动力学稳定。结论经食管超声多普勒可以动态瞬时监测患者的血液动力学,全面了解患者的心脏功能和循环状况,是一种指导大手术中液体治疗的有效的无创监测手段。

Objective To evaluate the signifiacance of transesophageal Doppler monitoring for fluid therapy in patients undergoing partial hepatectomy. Methods Forty patients undergoing partial hepaectomy were randomly divided into two groups. In experiment groups, transesophageal Doppler was used to monitor the hemodynamics for the guidance of fluid infusion. In control group, central venous pressure（CVP） was used instead of Doppler. The hemodynamics, fluid volume infused and the outcomes were observed. Results The hemodynamics of the patients guided with transesophageal Doppler monitoring was more stable than that with CVP. Conclusion Transesophageal Doppler monitoring is an useful technique for dynamically monitoring circulatory function and derecting fluid therapy in the patients undegoing major operation.
