We don't use benzodiacepines in preterm babies. We rotate to morphine sulfate+ extra dose of skin to skin contact (if parents are available) This cases are very difficult to manage.... Good luck!
We usually leave UVC no more than 6-7 days and UAC no more than 4 days. The problem comes when the UVC is malpositioned (intrahepatic or low position).... what do you do in this cases?
