One double lumen oximetry pediasat catheter was returned for evaluation.Customer report of catheter insertion issue could not be confirmed during evaluation; however, a general examination was performed to the returned sample, and the distal end of the backform was found to be slightly deformed.No other visible damage to the returned catheter was observed during visual examination.A lab guidewire was passed hub to tip and tip to hub of returned catheter without problem.Blood could not be fully removed from the proximal lumen.The distal lumen was found to be patent and did not leak.The catheter was sent for further dimensional evaluation.Visual examinations were performed under microscope at 10x magnification.The lot number was not provided; therefore, a review of the manufacturing records could not be completed.A supplemental report will be sent with the dimensional evaluation results.Invasive procedures involve some patient risks.Although serious complications are relatively uncommon, the physician is advised, before deciding to insert or use the catheter, to consider the potential benefits in relation to the possible complications.The techniques for insertion, methods of using the catheter to obtain patient data information, and the occurrence of complications is well described in the literature.In this case, the patient required a new stick during the procedure to insert a new catheter.It is unknown whether user or procedural factors contributed to the stated event nor were there any patient complications reported.Complaint histories for all reported events are reviewed against trending control limits on a monthly basis, and any excursions above the control limits are assessed and documented as part of this monthly review.
