控制性低中心静脉压联合肝血流阻断在肝癌切除术中的应用

Application of controlled low central venous pressure combined with hepatic blood occlusion in hepatectomy

  • 摘要: 目的:观察控制性低中心静脉压(controlled low central venous pressure,CLCVP )联合肝血流阻断对肝切除术中出血及血流动力学变化的影响。方法:选取天津医科大学肿瘤医院2014年6 月至2014年12月60例肝叶/ 段切除术患者,随机分成肝血流阻断组(Ⅰ组)和肝血流阻断联合CLCVP 组(Ⅱ组)。 Ⅰ组在肝切除过程中只应用肝血流阻断技术,采用常规液体管理,维持中心静脉压(central venous pressure,CVP )为6~12cmH2O;Ⅱ组在肝切除过程中联合应用肝血流阻断和CLCVP 技术。CLCVP 包括:限制液体输入和输注硝酸甘油,即从手术开始到肝实质分离完成时,液体输注速度控制在1~3 mL/(kg · h)左右,并以输注晶体液为主,必要时输注硝酸甘油,维持CVP ≤ 5 cmH2O;在肝切除后,快速输入乳酸钠林格氏液和羟乙基淀粉130/ 0.4 氯化钠注射液,恢复正常 CVP 。记录两组患者基本情况和手术信息,记录术前、气管插管后 5 min、肝切除开始、肝切除 20min、肝切除后 5 min、手术结束时的平均动脉压(mean arterial pressure ,MAP )、心率(heartrate ,HR)、CVP 、脑电双频谱指数(bispectral index,BIS)等。结果:与Ⅰ组相比,Ⅱ组手术时间、出血量、输血量均明显减少(P < 0.05),两组尿量无显著性差异(P > 0.05)。 两组患者术前各项指标比较无显著性差异(P > 0.05)。 术中不同时点,两组患者MAP 、HR也无显著性差异(P > 0.05)。 与Ⅰ组相比,Ⅱ组CVP 在肝切除开始及肝切除20min时显著下降(P < 0.05),BIS值在肝切除开始、肝切除20min及肝切除后5 min显著降低(P < 0.05)。 结论:肝血流阻断联合应用CLCVP 技术能够有效降低肝切除术的术中出血量和减少输血。

     

    Abstract: Objective:To investigate the effect of controlled low central venous pressure (CLCVP) combined with hepatic blood occlusion on blood loss and hemodynamics in hepatectomy. Methods:Sixty hepatocellular carcinoma patients with American Society of Anesthesiologists (ASA) Ⅰ- Ⅱundergoing hepatectomy were randomly divided into two groups. One was the group of hepatic blood occlusion (group I); the other was the group of CLCVP combined with hepatic blood occlusion (group II). During the parenchy-mal transection phase of surgery, 60.05). Likewise, no significant difference was noted in MAP and HR at different time points of the two groups (P>0.05). The CVP in group Ⅱwas significantly lower than that in group Ⅰat the beginning of and 20min after the paren-chymal transection phase of the surgery. Conclusion:CLCVP combined with hepatic blood occlusion can reduce blood loss effectively during hepatectomy.
