The NIPA Study Naloxegol Administration to Prevent Opioids Induced Gastrointestinal Motility Disturbance in Brain Injured PAtients

Summary

Impaired gastrointestinal transit (IGT) especially constipation, is common among patients under mechanical ventilation, occurring in up to 80 % of the patients during the first week, and has been associated with worse outcome in intensive care unit (ICU). Although IGT in critically ill patients is multifactorial and some components are due to complex disease, there is increasing evidence that exogenous opioids contribute to bowel dysmotility. Sedatives and especially opioids are largely used in the brain injured population to control intracranial pression, reduce metabolic rate, manage or prevent seizures, and improve mechanical ventilator synchrony. Therefore, brain injured patients are particularly at risk to develop IGT. The occurrence of IGT is associated with adverse outcomes in intensive care unit. Both gastric reflux and impaired peristaltic contractions are associated with ventilator-acquired pneumonia. The actual challenge is to prevent motility disorders before it occurs. A preventive strategy could in turn reduce the occurrence of complications related to impaired gastrointestinal transit such as ventilator-acquired pneumonia, bacteremia etc. It could also reduce the complications of feed intolerance and thus reduce morbidity and mortality in ICU. Naloxegol is a polyethylene glycol derivative of naloxol, which is a derivative of naloxone and a peripherally acting µ-opioid receptor antagonist. Contrary to naloxone, naloxegol has a very low penetration into the central nervous system, therefore it could be a relevant option for ileus prevention without the risk of impaired sedation. The aim of our study is to assess the efficacy of the administration of naloxegol on the onset of early constipation and early ventilator-acquired pneumonia in brain injured patients receiving opioids for analgosedation.
