Does PEEP impair the hepatic outflow in patients following liver transplantation?
BIPAP ventilation with PEEP levels up to 10 mbar does not affect systemic hemodynamics. Furthermore, neither venous outflow nor portal venous or hepatic artery inflow of the liver are impaired at PEEP levels up to 10 mbar immediately following liver transplantation. Although these results suggest that PEEP ventilation up to 10 mbar does not affect liver hemodynamics, further studies are needed to determine whether these findings could be confirmed for a longer ventilation period with PEEP.
These results indicate that enhanced expression of telomerase activity occurs early during human oral carcinogenesis and support the critical role of telomerase in the development of human oral cancer.
