Summary |
Background |
Various clamping procedures are used to decrease bleeding during liver resections but their effect on central venous pressure (CVP) remains unclear. The aim of this study was to assess the variations of the CVP during two different clamping procedures.
Methods |
We retrospectively reviewed 29 patients (19 males, 10 females) who had Pringle maneuver (PM) and clamping of the inferior vena cava below the liver (IVCC) during major liver resections.
Results |
Mean decrease of the CVP after PM, IVCC, and PM+IVCC was 0.84±1.37, 2.17±2.13 and 3.17±2.56 cmH20, respectively (P=0.02, P<0.0001 and P<0.0001, respectively). IVCC was more effective in inducing a decrease of the CVP than PM alone (P<0.05). The combination of both PM and IVCC induced the greatest decrease but not to a level of significance compared to IVCC alone (P=0.25).
Conclusion |
IVCC remains the more efficient procedure to lower the CVP. However, although PM is commonly used to control vascular inflow within the liver its significant influence on the CVP could participate to the reduction of bleeding during liver resections.
