Did you connect the hemofiltration pre pump? Never do this, you have a deep negative pressure there and in case of unlocking the luer or a cap you risk massive air embolism to the patient! Always place it on the positive pressure parts of the ECMO. We place it on the upper luer of the PLS - Oxygenator to take the blood out of the patient and give it back on the blood sample luer (oxygenator outlet).
Think about connecting the ECMO directly to the bed - prevents from unintentional decanulation.

接法怪怪的
CRRT的A端從ECMO的pre-pump 拉血會有問題
1.缺氧血沒經過氧合就重CRRT的管路回病人的A cannula.....這問題較小...
2.ECMO的pre-pump port是負壓,,,CRRT也從那邊拉血的話負壓會很大,,,尤其實當v-cannula拉血拉不順的時後兩個系統會一起遭殃
所以建議:
1.如果只是要洗CVVH的話,就改用CAVH的方式洗,不用多一台洗腎機當pump血的工 具
2.非得要外接洗腎的話,CRRT的AV端都設在氧合氣後方,,,但你要保證不會有air in line的問題,,,因為沒氧合氣檔著,,air會直接進到病人體內
