Ultrasound-guided Peripheral Vascular Access in Children

Ultrasound-guided Peripheral Vascular Access in Children - a Single- Blind, Randomized, Cross-over Trial

The purpose of this investigation is to conduct a randomized, patient-blinded prospective controlled trial comparing peripheral intravenous cannulation in children done by:

1. Conventional landmark cannulation where the intravenous cannulation is done by direct visual guidance or palpation or a combination thereof.
2. Ultrasound guided cannulation by means of DNTP.

The investigators hypothesize that with ultrasound-guided peripheral intravenous cannulation the first-attempt success rate will be significantly higher than by the conventional landmark cannulation technique.

Inclusion Criteria:

• Requirement for anaesthesia before MRI or operation.
• Routine need of peripheral intravenous cannulation.
• Age 0- 3 years at the date of MR scan

Exclusion Criteria:

• Lack of consent
• Emergency patients needing immediate operation or scan.
