Answer

Different scoring systems have been developed for assessing the severity of neonatal abstinence syndrome, such as those by Finnegan, Ostrea, Lipsitz, Rivers, and the Neonatal Intensive Care Unit Network Neurobehavioral Scale (NNNS). [41, 42, 43] These are based on opiate withdrawal and may not be entirely appropriate for the infant exposed to cocaine or other drugs.

The most widely used system is the Finnegan scoring system, in both its original and modified forms. A NAS scoring form is shown below.
