Abstract:
Objective To investigate the effect of carbon dioxid insufflation on cerebral blood flow (CBF) during laparoscopic cholecystectomy. Methods Thirty patients ASA grade Ⅰ- Ⅱ undergoing laparoscopic cholecystectomy were selected. The values of jugular venous oxygen partial pressure(PjvO2 ) jugular venous oxygen saturation (SjvO2 ), arterial partial pressure of carbon dioxide (PaCO2), oxygen (PaO2) and saturation (SaO2 ) were measured before the insufflation, 10 min and 30 min after the insufnation, respectively. Results Compared with those before the insufflation, SjvO2 and PacO2 were increased significantly, and arterial--jugular venous oxygen content difference (Ca-jvDO2 ) decreased markedly 10 min and 30 min after insufflation (P
