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

Area of Science:

• Neonatal Intensive Care
• Vascular Access Procedures

Background:

• Percutaneous catheterization is crucial for critically ill newborns.
• The Modified Seldinger Technique offers potential advantages over traditional methods.

Purpose of the Study:

• To describe the implementation of the Modified Seldinger Technique for percutaneous catheterization in critically ill newborns.
• To assess the impact of theoretical-practical training on nurses' assertiveness and technique execution.

Main Methods:

• A quasi-experimental before-and-after study was conducted in a Neonatal Intensive Care Unit.
• Seven neonatologist nurses participated, with catheterization steps assessed using conventional and modified Seldinger techniques.
• Reliability of technique execution was evaluated through pre- and post-training assessments.

Main Results:

• Nurses demonstrated satisfactory reliability in catheter pre-insertion and maintenance, improving post-training.
• Perfect reliability was achieved in device insertion and maintenance post-training.
• Areas needing improvement included indication, ultrasound-guided microintroduction, limb repositioning, and disinfection.

Conclusions:

• Theoretical-practical training significantly enhanced nurses' assertiveness in using the Modified Seldinger Technique.
• The Modified Seldinger Technique was successfully implemented and is undergoing further integration into clinical practice.
• This training approach supports the adoption of advanced percutaneous catheterization methods in neonatal care.
