I am a NNP developing a Level II nursery with a significant NAS population. Current practice in this nursery only requires 8-hours of CR monitoring once pharmacologic therapy is started with morphine 0.04 mg/kg every 3 hours. My experience at a large level III NICU was to continue monitoring until morphine is discontinued. To optimize safety and outcomes, I need data regarding onset of adverse events associated with morphine administration in NAS babies at different stages of recovery to support this practice. Any input is appreciated, as I was unsuccessful finding specific information supporting continued monitoring in the literature, although this is a standard practice in large centers and empirically makes sense.
