Brief Summary

Dynamic preload variables like pulse-pressure and stroke volume variation may be used to predict fluid responsiveness in patients during controlled ventilation. Previous work has shown that a rapid decrease in intra-abdominal pressure may lead to an increase in dynamic preload parameters, suggestive of a fluid deficit - despite fluid status had not changed \[van Lavieren M 2014\]. The results of this study are limited by the fact that a non-invasive and uncalibrated hemodynamic monitoring system (Nexfin™) was used. The present study thus aims to evaluate the effects of abdominal pressure changes on dynamic preload parameters (PPV and SVV) employing conventional, invasive hemodynamic monitoring (Vigileo®, Edwards Lifescience) in open abdominal surgery as well as in minimal invasive surgical procedures with pneumoperitoneum.

Outcome Measures

Primary Outcomes (1)

  • Influence of pneumoperitoneum or open abdominal surgery on dynamic preload parameters

    Mesurements during one minute after induction of pneumoperitoneum or open abdominal surgery

Secondary Outcomes (2)

  • Influence of pneumoperitoneum or open abdominal surgery on cerebral oxymetry

    Mesurements during one minute after induction of pneumoperitoneum or open abdominal surgery
