The event occurred on an unspecified date and involved a 112" 15 drop primary set w/3 microclave®, 3-port nanoclave® manifold, check valve, rotating luer.The anesthesia provider reported that the device had check/regurgitation valve failures preventing in-line pharmaceutical delivery via syringe from traveling upstream into spiked fluid bags (usually containing crystalloids).Some of the facility's medications are opaque and easily observed in the tubing.However, for medications that are not opaque, it is impossible to determine the direction of travel (where there is less resistance), usually toward the spiked fluids.This would render the infusion to be ineffective.The customer reported that it would be even worse if a patient received part of a pharmaceutical medication at strength, therefore only achieving a partial desired reaction.For example, a patient could become unconscious during the anesthesia induction, but not at the depth needed for surgery.Subsequently, a partial dose may provide only a portion of the desired effect, leaving the provider unable to determine treatment plan efficacy.The complainant further indicated that subsequent potential catastrophic outcomes could occur.An in-house trial alleged a 30% failure within the reported lot number.There was no actual or specific human harm reported.
