Today was a crazy day because there was a shortage of lidocaine. If you go to the dentist they use lidocaine as well which is a numbing injection that allows the patient to not feel as much pain during procedures. This was especially concerning in a dermatologist’s office to have a shortage because lidocaine is used frequently during incisions and even before cosmetic fillers and Botox treatments. Dr.Boyse taught me how to fill lidocaine in syringes from a bottle and even let me practice doing them a couple times. We also saw lots of warts between fingers, toes, hands and the solution was using liquid nitrogen to freeze the spots. This year I saw liquid nitrogen not only in adv chem class at school but I saw it being used a ton in the dermatologists office! Keratosis pilaris which is a common, harmless skin patch is often concerned by patients to be skin cancer is treated by freezing the spot until it falls off. Often it takes a couple times for it to fully freeze before it fully separates from the skin barrier.
Here is a picture of a liquid nitrogen bottle!
