Vein Finder in Uganda: Single-Attempt Cannulation for Children in Resource-Limited Settings

In low- and middle-income countries, children often arrive at hospitals dehydrated, severely malnourished, or critically ill. Their veins collapse or become nearly invisible — and with darker skin, visual identification is even harder. Failed cannulation can delay treatment by up to 30 minutes and require as many as nine puncture attempts.

A vein finder device developed for this exact setting has been clinically tested across four hospitals in Uganda, with promising results.

The device
A vein finder device using red light absorption by deoxygenated hemoglobin to distinguish veins from surrounding tissue. Veins appear as dark lines against a lighter background, making them visible even through darker skin.

The study design
The device was tested on 214 patients across four Ugandan hospitals. The evaluation focused on cannulation attempts, procedure time, and medical waste reduction.

The results

• Cannulation attempts: reduced to a single attempt

• Medical waste (syringes, needles): reduced to under 5%

• Procedure time: shortened to under 60 seconds

• Clinician acceptance: in a 2022 needs assessment, 91.8% of surveyed healthcare workers said they would purchase the device, comparing its importance to a stethoscope in daily practice

Why it matters
This case demonstrates that effective vein visualization does not require expensive, specialized equipment. A portable device priced at approximately $150 per unit can serve as a daily frontline tool in hospitals where both resources and visible veins are scarce. For healthcare providers in Africa, South Asia, and other regions serving patients with dark skin and limited vascular access, this data supports vein finder devices as a practical, affordable standard of care — not a luxury.
