Central venous access in the radiology department : A literature review on patient safety and image quality (English)
Abstract [sv]

Centrala venösa infarter används inom vården för att administrera läkemedel, ge parenteral nutrition och för blodprovstagning. Indikationer på att en patient behöver en central venös infart är att patienten behöver akut vård eller långvarig intravenös administrering av läkemedel. Många av dessa patienter behöver dessutom genomgå undersökningar via datortomografen (DT), där kontrastmedel kan krävas för att undersökningen ska kunna utföras. Syfte: Syftet med litteraturöversiktet var att sammanställa kunskap om centrala venösa infarters användbarhet vid administrering av kontrastmedel i samband med DT undersökningar. Metod: En allmän litteraturöversikt som baseras på tolv kvantitativa artiklar. Resultat: I de tolv artiklarna så uppmärksammades fyra kategorier som syftar till användbarheten: Tryck och Flödeshastigheter, Kateterspetsläge, Efterspolning och Diagnostisk bildkvalitet. Flera av studierna visade på kateterspetsförskjutning i samband med en kontrastmedelsinjektion med tryckspruta på DT. Tre av de fyra studier som kontrollerade bildkvalitet visade på bra diagnostisk bildkvalitet. Slutsats: Centrala venösa infarter är användbara vid administrering av kontrastmedel under datortomografiundersökningar under förutsättning att röntgensjuksköterskan har rätt kunskap om användandet av dem. Nationella riktlinjer behövs för att underlätta röntgensjuksköterskans arbete med dem så att hanteringen av dem utförs patientsäkert.

Abstract [en]

Central venous access is used in healthcare for drug administration, blood sampling, and providing parenteral nutrition. Indications for a patient needing a central venous access are either that a patient needs urgent care or prolonged intravenous administration of drugs. Many of these patients also need to undergo examinations via computed tomography (CT), where contrast agents may be required for the examination to be performed. Purpose: The purpose of the literature review was to compile knowledge about the usability of central venous access during the administration of contrast agents in connection with CT examinations. Method: A general literature review based on twelve quantitative articles was performed. Result: In the twelve articles, four categories were observed with the aim being usefulness: Pressure and Flow Rates, Catheter Tip position, Flushing and also Diagnostic Image Quality. Several of the studies showed catheter tip displacement being in connection with a contrast injection of a syringe during the CT examinations. Three of the four studies that controlled image quality showed good diagnostic image quality. Conclusions: Central venous access is useful in the administration of contrast agents during computed tomography examinations, provided that the radiographer has the correct knowledge of their use. National guidelines are needed to facilitate the radiographers work with them so that their usability is carried out with patient safety in mind.
