KCER Release Date: March 25, 2026 To: KCER Distribution list- including ESRD Network EDs and QIDs Affected Product The FDA is aware that B. Braun Medical Inc. has issued an Urgent Medical Device Correction to affected customers recommending certain Streamline Airless System Hemodialysis Bloodlines and B3 Low Volume Bloodlines only be used if no alternative is available. Affected devices:
What to Do Use alternate dialysis equipment. If you do not have access to alternate equipment and need to administer treatment, follow the instructions below to help mitigate potential harm. On March 19, B. Braun Medical Inc. sent all affected customers a letter recommending the following actions:
Check this web page for updates. The FDA is currently reviewing information about this potentially high-risk device issue and will keep the public informed as significant new information becomes available. Reason for Alert B. Braun Medical Inc. has preliminary testing showing that a change to the tubing resin has led to small air bubbles adhering to the inside of the arterial bloodline, in the segment between the patient connector and the blood pump. These bubbles are the result of degassing of blood on the arterial side of the blood pump due to the negative pressure within the tubing and are not being drawn into the bloodline from the external environment. With the previous tubing resin, these bubbles remained in the blood and were compressed or dissolved via the positive pressure applied post blood pump. With the new resin, these small bubbles adhere to the inside of the bloodline and may gather to form larger bubbles. This process of degassing and bubble formation normally begins approximately 60 minutes into dialysis treatment. Air bubbles detected in the line during use may lead to a delay in treatment to replace the set and resume therapy. If the operator does not replace the set, it may result in less efficient treatment. If the safety air detector in the dialysis machine detects the bubbles, the machine will alarm and automatically stop treatment. The operator must respond to the alarm to continue treatment, which may include replacing the set and/or monitoring treatment. Patients may experience moderate blood loss if it is not clinically feasible to return the blood in the extracorporeal circuit to the patient. In some patients, blood loss may lead to life-threatening adverse events, including death. As March 20, 2026, B. Braun Medical Inc. has not reported any serious injuries or deaths associated with this issue. Device Use Bloodline tubing sets are a collection of tubing segments and associated devices like connectors and clamps that are intended to transfer blood between a patient’s vascular access device and a hemodialyzer during hemodialysis.
