A patient was treated with therapeutic plasma exchange (tpe) for the first time.The therapy was started using a prismaflex tpe 2000 set (which had been primed using 3 liters of saline) and a prismaflex control unit, as well as 4% albumin as replacement solution.Anticoagulation was achieved using 200 units of heparin as a loading dose then infusion of 500 units/hour.Blood flow was set at 300ml/min, and the replacement of 3.6l of plasma was planned.Thirty minutes into treatment, during the infusion of the first bag of 4% albumin, the patient presented with hypotension, nausea, vomiting, chills and lower back pains.Due to this event, the plasma removal and the infusion of 4% albumin was stopped (blood was still circulating in the prismaflex tpe 2000 set), and the patient received 100 ml of saline solution and 50 mg of tramadol.Around 10 minutes after the apparition of the symptoms, the patient started feeling better.An electrocardiogram (ecg) was performed which showed a right branch block.Tpe treatment was then discontinued, and the patient was addressed to a cardiologist (outcome not reported).No additional information is available.
