Parameter

Dexmedetomidine

Remifentanil

References

Sedative Effectiveness

Effective sedation with deeper levels in certain procedures

Effective sedation, typically with faster recovery

[7,8]

Analgesic Effectiveness

Lower postoperative pain scores; reduced opioid consumption

Effective analgesia, standard in many protocols

[6,9]

Hemodynamic Stability

Maintains hemodynamic stability; notable for hypotensive effects

Maintains stability; quicker recovery from hypotensive effects

[5,7]

Respiratory Adverse Events

Fewer respiratory adverse events, but longer recovery times

More respiratory events, but quicker discharge

[8]

Postoperative Recovery

Longer extubation times and PACU stays

Shorter extubation times and quicker recovery

[5,6]

Side Effects

Lower incidence of shivering, nausea, vomiting; higher incidence of bradycardia

Less bradycardia, but higher incidence of shivering, nausea, vomiting

[5,6,7,8]

Propofol-Sparing Effect

Sparing effect observed, which may reduce the need for propofol

Not typically associated with a propofol-sparing effect

[9]

Patient/Surgeon Satisfaction

Higher satisfaction in certain procedures (e.g., DMEK)

Standard satisfaction

Often favored for quick recovery

Considerations

·      Dexmedetomidine offers advantages like reduced postoperative pain and fewer opioid-related side effects but may lead to longer recovery times and increased bradycardia risk.

·      Dexmedetomidine's role as an effective alternative during fentanyl analog shortages highlights its importance, but careful monitoring and risk assessment are crucial.
