If criteria for pharmacotherapy are met per a hospital-specific written guideline, morphine every3 hours as needed (PRN) may be trialed as an initial strategy for the treatment of neonatal abstinence syndrome (NAS) instead of scheduled dosing or more long-acting pharmacotherapy options.
Overview
Why we are recommending this best practice
Signs of NAS are not consistent throughout the day, nor is parental presence. Pharmacologic treatment may not be necessary every 3 hours. PRN dosing of morphine may minimize pharmacotherapy exposure and therefore side effects from scheduled morphine doses (e.g., respiratory depression, bradycardia, hypotension, urinary retention, decreased intestinal motility) or long-acting pharmacotherapy such as methadone.
Strategies for implementation
Incorporate guidelines for initiation of PRN morphine for the treatment of NAS into the hospital’s guideline when a newborn meets criteria to initiate pharmacotherapy. Consider including guidelines to describe a threshold for escalating to scheduled q3 hour dosing and when to escalate the dose of scheduled morphine. Consider cardiorespiratory monitoring continuously or intermittently when the newborn is receiving morphine.
