No results posted yet for this study

Summary

Pulse pressure variation (PPV) is a well-known dynamic preload indicator to predict fluid responsiveness. However, its usefulness in open-chest conditions has been equivocal. The investigators evaluated whether PPV measured during Valsalva maneuver can predict fluid responsiveness after sternotomy.

Conditions

  • Cardiac Surgical Procedures
  • Thoracic Surgical Procedures
  • Sternotomy

Interventions

PROCEDURE

Valsalva maneuver

Valsalva maneuver was performed after sternotomy with the constant airway pressure of 30cmH2O for 2 breaths duration.

OTHER

Fluid loading

We record the cardiac index values before and after volume expansion with 6ml/kg of balanced crystalloid
