A device history record review was completed for provided material number 306585 and lot number 3235050.The review identified two (2) quality notifications during the production process; however, all affected product was scrapped in both cases and no product was released to the market.There was no issues documented which could have affected the saline solution and all inspections and controls were reviewed and found to be acceptable.To aid in the investigation of this issue, two (2) shelf cartons of product were received for evaluation by our quality team.The samples were tested for appearance and solution clarity.As per the test results, there were no issues identified with solution clarity or appearance/syringe clarity.The test examines the appearance and solution clarity of the posiflush sp syringes and associated materials by comparing them to a solution of reference and a syringe of reference against two (2) types of backgrounds (black and white).The results show no saline solution clarity issues.The plastic material used to mold the barrel may be less transparent than others used by other manufacturing plants so it may seem the solution is cloudy.As per customer input, patients had a metallic aftertaste.As per the characteristic described, it could be associated with a distortion of the sense of taste, known as dysgeusia.Dysgeusia has been subject of a series of in-depth investigations by bd.In addition to biocompatibility testing, bd has conducted extensive chemical, biochemical, analytical, and biological testing of relevant materials.These investigations confirmed the absence of any significant risk to the patient¿s health following single or repeated exposure to bd posiflush¿ syringe contents.It was concluded that while unpleasant to the patient, this effect has no clinically relevant medical consequences.Bd posiflush¿ syringes continue to meet or exceed all standards applicable to these syringes.Bd fraga performs heavy metals tests for each lot number since dysgeusia could be related with a high presence of heavy metals in the saline solution.For the reported lot, all tests were accepted as per specification.At this time, further action has not been determined necessary.Our quality team will continue to closely monitor the manufacturing process for signs of this potential defect and any emerging trends.
