Implementation of modified Seldinger technology for percutaneous catheterization in critically ill newborns

Objective: To describe the implementation of Modified Seldinger Technology for percuta- neous catheterization in critically ill newborns. Method: A quasi -experimental before- and -after study, carried out with neonatologist nurses in a Neonatal Intensive Care Unit. Results: Seven nurses participated in the research. Catheter pre -insertion, insertion and maintenance were assessed using the conventional and modified Seldinger technique. Reliability was satisfactory in pre-test, 5.40 (Md = 6.00), and post-test, 5.94 (Md = 7.00), and perfect in the items about device insertion and maintenance. There was low assertiveness in the items on indication, microintroduction procedure via ultrasound, limb repositioning and disinfection of connections/connectors. Conclusion: Despite the Modified Seldinger Technique expanding some stages of execution over the traditional method of percutaneous catheterization, nurses were more assertive after theoretical -practical training. The technology was implemented and is in the process of being implemented in the health service.
