Safety and Efficacy of a Low Dose Naloxone Infusion in NICU Patients
When narcotic pain medicine, like fentanyl or morphine, is given to adults and children for several days, they often develop a tolerance to the medicine. This means they may need higher doses over time to get the same amount of pain control. When it is time to stop the medicine, the dose has to be decreased slowly so that the patient does not have withdrawal symptoms.
Naloxone is a medicine that at high doses can reverse the effects of narcotics. At very small doses it may help prevent tolerance and lessen the severity of withdrawal symptoms. This could mean less narcotic pain medicine is needed over fewer days.
The purpose of this research study is to see if giving naloxone to neonates who require narcotic infusions is safe and effective. Safety will be measured by the incidence of side effects. Efficacy will be measured by monitoring for changes in pain and sedation scores and need for more pain medicine.

|Official Title:||Safety and Efficacy of a Low Dose Naloxone Infusion in NICU Patients|
- The primary outcome variable will be a change in N-PASS scores. N-PASS scores will be compared before, during, and after administration of naloxone. [ Time Frame: Before, during, and after administration of naloxone ] [ Designated as safety issue: No ]
- The secondary outcome variable will be any changes in dosing of opioids within four hours of initiating or increasing naloxone infusion. Vital signs will be recorded per NICU protocol and closely monitored for changes. [ Time Frame: Collected and compared for the time period before, during, and for 5 days after naloxone infusion is administered ] [ Designated as safety issue: Yes ]

This is a prospective, non-randomized, single center, open label dose escalation study. We hypothesize that critically ill patients in the NICU may benefit from a low dose naloxone infusion resulting in decreased tolerance, less severe withdrawal symptoms, lower cumulative doses of opiates, and fewer total days of opiates, all while maintaining adequate or enhanced pain control and sedation. Establishing safety and efficacy data for this potentially beneficial therapy is an important first step towards using this therapy to decrease the risk of opioid tolerance and withdrawal in this population of infants.
