Using the Accuvein Device for Patients Who Are Difficult to Perfuse

Using the Accuvein Device for Patients Who Are Difficult to Perfuse

Prior to any examination related to the clinical investigation, the investigator (IDE) will check the eligibility criteria of the person undergoing the research, and will inform and obtain the free, informed and written consent of the person undergoing the research.

The patient will then be randomised into one of two groups (insertion of a intravenous route with the AccuVein device vs. insertion of a VVP without the AccuVein device). After randomisation, the TEC or qualified person starts the stopwatch as soon as the tourniquet is applied.

The nurse makes a first attempt to perfuse the patient. The TEC or the qualified person will stop the stopwatch when the nurse checks the patency of the first attempt at perfusion and signals its success, or when the nurse withdraws the needle if the first attempt is unsuccessful. The pain felt by the patient will be assessed by the nurse using the self-assessment scale from 0 to 10 at the end of the first attempt.

If the first attempt at VVP insertion fails, the choice of conditions and personnel involved in carrying out further attempts will be left to the discretion of the nurse.

Inclusion Criteria:

• Age ≥ 18 years
• Patients who are difficult to infuse according to the nurse's subjective assessment after the tourniquet has been applied; this may particularly concern patients who are obese, dark-skinned, multi-drug users, sickle-cell anaemia sufferers, drug addicts, elderly with fragile skin and subcutaneous haematomas

• Patients affiliated to a social security scheme

• Person deprived of liberty by administrative or judicial decision or person placed under court protection/guardianship or curatorship
