How Infrared Vein Finder Technology Improves Infant Care: Insights from a Clinical Study

In neonatal intensive care units (NICUs), venipuncture is a common but painful procedure—especially for preterm infants. Traditional techniques often rely on visual inspection and palpation, leading to multiple failed attempts and increased discomfort. Fortunately, infrared vein finder technology is changing that.

A recent study published in BMJ Paediatrics Open (2025) provides compelling clinical evidence that vein finder devices not only improve procedural efficiency but also significantly reduce pain and stress responses in preterm infants during venipuncture.

Comparing the effects of vein finder technology and traditional venipuncture on pain and behavioural states in preterm infants

Why Infrared Vein Finders Matter in Neonatal Care

Preterm infants are especially vulnerable to pain due to their immature nervous systems and fragile veins. Repeated needle punctures can lead to serious complications, including phlebitis, infiltration, and long-term developmental effects.

Infrared vein finders use near-infrared (NIR) light to detect hemoglobin in blood vessels and project a real-time map of veins on the skin’s surface. This technology helps healthcare providers identify optimal injection sites quickly and with higher accuracy, minimizing trauma and improving outcomes.

Key Findings from the Study

This quasi-experimental study involved 124 preterm infants in two Egyptian NICUs—62 received traditional venipuncture, while the other 62 were treated with the help of vein finder technology. The results were striking:

Pain Reduction: Infants in the vein finder group had significantly lower Neonatal Infant Pain Scale (NIPS) scores (5.71 vs. 6.73).

• Better Behavioural States: The study group spent more time in deep sleep and less time crying or in an alert state post-procedure.
• Higher First-Attempt Success Rates: 87.1% success with vein finders compared to 46.8% with traditional methods.
• Fewer Complications: Lower incidences of infiltration and phlebitis.
• Shorter Procedure Time: Vein finder use resulted in faster cannulation (average 3.4 minutes vs. 6.06 minutes).

Clinical and Operational Benefits

Implementing infrared vein finder technology in NICUs offers numerous advantages:

• Enhanced Patient Comfort: Reduced pain and distress support better neurodevelopment.
• Improved Workflow: Fewer attempts mean more efficient care and lower burden on staff.
• Cost-Effective: Though the initial investment is higher, reduced complications and improved outcomes may lower overall hospital costs.

The Future of Neonatal Venipuncture

This study reinforces the growing body of evidence that infrared vein finder devices are not just helpful—they’re essential tools in modern neonatal care. As medical facilities prioritize both efficiency and compassion, vein visualization technology stands out as a vital innovation.
