My son has had laser with pulse dye (v-beam brand) done both ways... without g.a for test spots..about 7 pulses.* Then the remaining treatments he had under g.a because it is a very large area and too close to his eye.
It was very fast and he was only 4 months old... I compare the experience to having his immunizations... which get me choked up when he cries in pain...but it is over quickly (if a small area) and with Tylenol and a lot of spoiling*
* the baby and parents recover.*
For the first treatment MOST doctors do a lighter treatment to see how the skin and lesion react.* Ask your doctor about this and what to expect afterwards.* Color change, blisters, swelling, etc.*
Usually within the first day or two the baby's are back to normal and the laser tx. doesn't bother them anymore (like a sunburn)... and typically within 10 days the areas that were darker (purpla) are healed.* It can take up to 8 weeks to see the full results.* Don't be disappointed if you don't see drastic changes the first treatment.*
Please ask the doctor also about a protective sheild for her eye. My son's doctors put a special contact on his eye when he was under g.a and for the quick test spots we used glasses similar to the tanning bed type.
