Abstract:
Objective:To explore the changes of cerebra flow in retroperitoneoscopic surgery.Methods: Twenty-two patients undergoing retroperitoneoscopic surgery were selected.We measured Vm、Delt and PI with transcranial Dopple(TCD),and measured endothelin(ET),neurol peptide Y(NPY),Calcitonin gene-related peptide(CGRP) in plasma before CO2 insufflation,after CO2 insufflation,and after CO2 deflation.Results:Vm and Delt increased significantly at 30 min after pneumoperitonenum,and reached the peak at 90 min after pneumoperitonenum.PI decreased significantly 90 min after pneumoperitonenum.The plasma concentrations of ET and NPY increased significantly 60 min after pneumoperitonenum. Conclusion:Cerebra flow changes significantly in patients undergoing retroperitoneoscopic surgery,which is correlated to the changes of plasma CO2 and vascular bioactive substances.
