Event Description

A report was received on 05 feb 2021 from the nurse of a male patient, with a medical history including iga nephropathy, hypertension, gout and end stage renal disease, who stated the patient became unresponsive and diaphoretic approximately twenty minutes into his first hemodialysis treatment with the nxstage system on (b)(6) 2021. Symptoms resolved with return of the blood circuit via rinseback. Shortly after symptoms resolved (time not specified), the patient was rechallenged and within one minute became unresponsive with low blood pressure (104/62mmhg), diaphoresis and a decreased respiratory rate (nos). Emergency medical services (ems) were called and rinseback of the blood circuit was performed. Symptoms resolved prior to ems arrival and no medical intervention was required. Additional information was received on 10 feb 2021 from the nurse stating no dyspnea or apnea was associated with the decreased respiratory rate. The patient recovered without medical intervention and his physician prescribed a dialyzer from a different manufacturer for his ongoing hemodialysis treatments.
