About 1 hour and 30 minutes after the start of treatment, the systolic blood pressure dropped to the 50 mmhg level after the development of yawning.We performed leg elevation, electrolyte replenishment, and discontinuation of dialysis (ultrafiltration), but the blood pressure did not improve, so extracorporeal circulation treatment was discontinued.

Our view: there were no reports of product defects, etc.From the facility, and we determined that the cause of the adverse events was the patient's condition and method of use.When the blood pressure dropped, no symptoms such as nausea or a decline in the level of consciousness were observed in the patient, but it was surmised that systolic blood pressure of the 50 mmhg level "may cause serious damage to peripheral tissues".The case was judged to be a "serious" case.In addition, since a causal relationship between the adverse event and the product cannot be completely denied, it was determined that the mdr 30-day report applies.
