Effects of HFJV outside of the glottis on the blood gas and lipid peroxidation in dogs with hemorrhagic shock / 中国病理生理杂志

ABSTRACT

18 dogs with hemorrhagic shock were divided into 3 groups. Group Ⅰwascontrol, group Ⅱ and Ⅲ were jetted with air or oxygen respectively and continuouslyoutside the glottis by HFJV (frequency 80 beat/min, driving pressure 0.2 MPa, IE timeratio=12) during the uncompensated period. Results: Not much difference was foundbetween group Ⅰand Ⅱ in their blood gas, acid-base balance and plasma malondialdehyde(MDA). However, the P_aO_2, P_aCO_2, CO_2, combining power and plasma MDA in group Ⅲwere markedly higher than those of group Ⅰand group Ⅱ (P
