A Comparison of the First Attempt Success Rate of Cannulation Between the Accuvein Apparatus and Standard Technique

Patients who fulfilled the inclusion criteria and provided informed consent were assigned to one of two groups using a randomization program that assigned research participants into group A (AccuVein AV300 assisted intravenous catheter insertion) or group B (standard technique of insertion of the intravenous cannula). After pre-anesthetic evaluation, the research participant was brought to the operating room and standard monitoring were applied (EKG, SpO2, BP) if tolerated. Anesthesia was induced via face mask with sevoflurane in 100% O2. The anesthesiologist and resident decided on a site believed to be the best for cannulation and on the size of the venous cannula as 22g or 24g. When the supervising anesthesiologist deemed it appropriate, the venous cannulation was attempted, according to the randomization groups, either with the AccuVein device (group A) or blindly (group B). A rating of the vein attempted as either difficult or easy was established by the attending anesthesiologist.

Inclusion criteria

• Patients less than 18 years of age, American Society of Anesthesiologist Physical Status (ASA) status I, II or III, undergoing elective surgery or examination under anesthesia, which did not have existing intravenous access.

Exclusion criteria

• Existing intravenous access, malformations or infections at the potential site of insertion, need for emergency surgery, and inability or unwillingness of parent or legal guardian to give written informed consent.
