Difficult Intravenous Access in Pediatric Patients: Paramedical Care Using Ultrasound Guidance

Obtaining intravenous access is difficult in the pediatric population. Ultrasound-guidance allows real-time visualization of target veins which are invisible and impalpable. We hypothesize that the use of ultrasound by a trained nurse team would improve the success rate of peripheral intravenous catheter insertion in pediatric patients with difficult intravenous access, compared to palpation of the vein alone. For this study, when peripheral intravenous catheterization will be indicated in one of the participating pediatric services for an eligible patient, state-certified nurse investigators, trained in ultrasound guidance, will be contacted. After verification of eligibility criteria and all informed consents obtained, one of the investigators will randomize the patient in one of the 2 treatment groups under study: peripheral intravenous catheterization by visualization and palpation
