Flow Deviations in Infusion Pumps : The Role of the Administration Set (English)
Abstract [sv]

På Karolinska Universitetssjukhuset har det återkommande rapporterats om flödesavvikelser hos infusionspumpar. En hypotes är att pumpanvändare drar i infusionsaggregates silikondel när en infusion förbereds och att detta ger upphov till flödesavvikelser. Detta projekt fokuserar på att utreda om töjning av slangsetets silikondel kan orsaka flödesavvikelser. Projektet utvärderade tre grupper av slangset där två av grupperna bestod av infusionsaggregat vars silikondel töjdes till olika längder och en grupp fungerade som referensgrupp. Resultatet visar att silikondelen förlängs vid töjning samt att flödesavvikelser uppstår om töjningen är tillräckligt stor. Trots att flödesavvikelserna påvisats så bedöms töjningen som utförts vara mycket större än den töjning som utförts av vårdpersonalen. Därför bedömmer vi att flödesavvikelserna som rapporterats på Karolinska Universitetssjukhuset inte beror på denna typ av felhantering av slangset.

Abstract [en]

At Karolinska University Hospital, recurrent reports of flow deviations in infusion pumps have been observed. One hypothesis is that pump users pull the silicone component of the administration set when preparing an infusion, leading to flow deviations. This project focuses on investigating whether elongation of the silicone component of the administration set can cause flow deviations. The project evaluated three groups of administration sets, where two groups consisted of administration sets which were elongated to different lenghts, while one group served as reference group. Results show that elongation of the silicone component occurs and that flow deviations occur if the elongation is large enough. However, despite the observed flow deviations, the elongation performed in the study is considered much larger than what healthcare personnel typically apply. Therefore, we find it unlikely that the reported flow deviations at Karolinska University Hospital are due to mishandling of the administration set.
