據(jù)SSI呼吸代謝技術(shù)2022年1月20日最新參考信息，鎮(zhèn)靜劑右美托咪定可能有助于治療重癥監(jiān)護(hù)中的COVID19患者——但它如何影響呼吸和血壓？

右美托咪定可維持一定程度的鎮(zhèn)靜狀態(tài)，有利于降低機(jī)體的氧耗率，改善氧合。來(lái)自日本牙科大學(xué)的科學(xué)家采用Foxbox呼吸代謝技術(shù)構(gòu)建了如下圖所示的鎮(zhèn)靜大鼠呼吸與血壓測(cè)定裝置，進(jìn)行右美托咪定對(duì)自主呼吸成年大鼠心肺調(diào)節(jié)影響研究。

相關(guān)研究成果見2022年1月14日PLOS ONE在線論文“Effect of dexmedetomidine on cardiorespiratory regulation in spontaneously breathing adult rats"。
