Do transilluminators work on dark skin or obese adults where you

I've found them near worthless most of the time. Not worth the money IMO.

I have also found them basically worthless. I don't even think they work on light skin or any skin for that matter.

I think they are only useful on neonates.

Good to know. I was wondering the same thing when my staff asked me to start two difficult patients yesterday (one I got; one I didn't). I got the dark skinned individual but the other obese patient who had very very thick skin (his family even commented on his "alligator hide") I missed. He didn't even bleed when I stuck him, his skin was so thick.

They work well with neonates to locate a vein but you still need the skill to access and thread the catheter. Not so useful in the adult population. On dark-skinned individuals you sometimes have to be patient and find a vein by palpation. alot of times they are there,just not visible. Sometimes they can be extremely difficult to find and this is a situation where you can call an IV nurse (if available) to access with Ultrasound or place a PICC.
