Thank you for the opportunity to respond to the letter concerning our recently published manuscript. We also thank Dr Goel for his interest in our study and his remarks.
Concerning the controls in our study: each patient served as his own control, and it is clear from the data that the baseline was recorded prior to PPP in case of visceral perfusion.1 Unfortunately, we could not obtain hepatic and renal perfusion prior to the induction of anesthesia because of the limited possibility for introducing an ultrasound probe while the patient is awake. . . .
