About

The following ultrasonic findings are obtained at both time points before and after induction of anesthesia (T1) and after induction (T2) in normal children . Positive pressure ventilation (Tidal volume of 6-8 ml/kg and a positive exhalation pressure of 5 cmH2O) is applied after anesthetic induction.

1. Inferior vena cava diameter and distensibility
2. Hepatic vein Doppler
3. Portal vein Doppler
4. Splenic artery and vein Doppler
5. Renal artery and vein Doppler Based on this, the reference values for Doppler findings before and after anesthesia in normal children are obtained.
