  • This study aimed to compare the effectiveness, safety, and pharmacokinetics of remifentanil versus fentanyl for pain management in mechanically ventilated ICU patients.
  • A total of 196 patients were randomly assigned to receive either remifentanil or fentanyl, with both groups achieving high rates of effective pain relief and no significant difference in adverse events between the medications.
  • The study confirmed that remifentanil was non-inferior to fentanyl in managing pain, and showed that it had a rapid decline in blood concentration after administration ceased, indicating quick recovery from its effects.
