低流量麻酔に際してガス流量を気にする一方，周術期の吸入酸素濃度に私達はどれだけ関心を持っているだろうか？ 導入時の高濃度酸素投与は想定外の気道確保困難に備える確立した対処法の一つである．導入時の高濃度酸素は短時間でも容易に吸収性無気肺を生じる．近年，周術期の酸素濃度と手術創感染の関連が注目されている．2016年，WHOは創感染を減らす目的で全身麻酔下の手術患者に80％酸素投与を推奨したが，その優位性を否定する研究が相次いだこと，ガイドラインの根拠論文に浮上した疑義等により，ガイドライン第2版では推奨の程度を弱めた．酸素は治療域の狭い薬であるとの認識を持って適切な濃度を投与すべきである．
Nitrogen fixation (acetylene reduction) rates of nodules on intact field-grown soybean (Glycine max) subjected to altered oxygen concentration (0.06-0.4 cubic millimeter per cubic millimeter) returned to initial rates during an 8-hour transitory period. Hydroponically grown soybean plants also displayed a transitory (1-4 hours) response to changes in the rhizosphere oxygen concentration after w...
Aims and background: Nausea and vomiting is one of the most common and most annoying post-operative complications, therefore, the aim of this study was to investigate the effect of oxygen therapy with Venturi mask and CPAP mask on nausea and vomiting after cesarean section. Materials and methods: This quasi-experimental study was performed on two groups (control-intervention) on 90 candidates ...
background: both azadirachtin and rotenone, two botanical pesticides have shown inhibit the growth of cultured insect cells. the inhibitory effect of rotenone on cell growth is through disruption of electron transport chain, but exact mechanism of effect of azadirachtin on growth of cell is unknown. this study was carried out to compare the effect of these phytochemical on oxygen consumption by...
