Abstract: Continuous renal replacement therapy (CRRT) is a slow and continuous bedside blood purification therapy method that has the advantage of more stable hemodynamics compared to conventional hemodialysis. However, many studies have shown that hypotension is still one of the common complications of CRRT. It has been reported that the incidence of hypotension within the first hour of CRRT is as high as 43~64.6%, and is independently associated with in-hospital mortality. However, the risk factors affecting the occurrence of hypotension during CRRT have not been further studied. This article mainly elaborates on the risk factors for hypotension during CRRT, aiming to further guide clinical practice to effectively prevent the occurrence of hypotension and improve the prognosis of the patients.
