Examination on the reason for circuit replacement of continuous renal replacement therapy in ICU

Abstract

【Background】Prismaflex^®, which was launched in 2018, this feature is expected to reduce coagulation within the circuit. 【Method】We divided TR-55X^® （Toray Medical） and Prismaflex^® (Baxter) used in our hospital, in order to retrospectively compare the effects on coagulation within the circuit. 【Results】Frequency of unexpected circuit exchange was significantly higher in the P group (p=0.003). The returning blood pressure was significantly higher in the TR group (p=0.003). There were four “other causes” other than increased return blood pressure and increased inlet pressure only in the P group. 【Conclusion】There were many unexpected circuit changes with P group, due to blood coagulation in the hemofilter or deviations in the operating procedure; consequently, going forward, it was considered that the results could be improved by improving the hemofilter and mastering the operation.
