“The purpose of this randomized, prospective study was to determine whether the accelerated Seldinger technique (AST) offers significant safety advantages over the modified Seldinger technique (MST) for peripherally inserted central catheter insertion” Caparas et al (2014).

Abstract:

BACKGROUND: Placing a central venous access device via the internal jugular or subclavian vein entails significant risks to both patient and healthcare worker.

PURPOSE: The purpose of this randomized, prospective study was to determine whether the accelerated Seldinger technique (AST) offers significant safety advantages over the modified Seldinger technique (MST) for peripherally inserted central catheter insertion.

MATERIALS AND METHODS: Patients were randomly assigned to undergo introducer sheath insertion by means of either MST or AST. Primary outcome measures included time to completion of introducer sheath insertion, estimated blood loss, and success rate. Secondary outcome measures included vessel-to-air exposure events and unprotected sharps exposure.

DISCUSSION: While both insertion methods proved equivalent for successful vessel cannulation, AST was significantly faster (P = 0.0048) and resulted in less blood loss (P = 0.0295) than MST. Additionally, AST resulted in significantly fewer vessel-to-air exposure events (P < 0.0001) and unprotected sharps exposures (P < 0.0001). Although this was a relatively small and unblinded study, the high degree of statistical significance of the study results suggests that, for both patients and healthcare workers, AST is faster and safer than MST for PICC peelable introducer sheath insertion.
