Evaluation of opioid requirements in mechanically ventilated patients taking buprenorphine/naloxone prior to admission

J Crit CarePublished Retrospective cohort study

Authors' conclusion

Patients taking buprenorphine/naloxone prior to admission who are mechanically ventilated for at least 12 h may have opioid requirements similar to opioid-naïve patients and lower than opioid-tolerant patients.
