2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl may be administered in small, titrated boluses to manage immediate post-surgical discomfort before transitions are made to longer-acting opioids or oral medications.
3. Intensive Care (ICU)
In the Intensive Care Unit, fentanyl is regularly used as an infusion to offer constant analgesia for clients who are mechanically ventilated. Its brief half-life allows for more foreseeable "wake-up" tests compared to drugs like morphine.
Table 2: Clinical Application Summary
| Application | Role of Fentanyl |
|---|---|
| Pre-medication | To provide sedation and analgesia before moving to theatre. |
| Induction | To work together with induction representatives (like Propofol) for a smooth transition to unconsciousness. |
| Maintenance | To handle the surgical pain stimulus throughout the procedure. |
| Analgesic Supplement | Utilized in regional anaesthesia (like epidurals) to enhance discomfort relief. |
Mechanism of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding hinders ascending discomfort pathways, changing the understanding of and action to pain. It likewise increases the discomfort threshold.
- Onset of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Period: 30-- 60 minutes (making it extremely titratable).
- Metabolic process: Primarily in the liver by means of the CYP3A4 enzyme.
- Excretion: Mostly via the kidneys.
Because fentanyl is highly lipid-soluble, it crosses the blood-brain barrier almost quickly, which discusses why the analgesic effect is felt so much faster than with morphine or oxycodone.
Security and Side Effects

- Queasiness and Vomiting: Common in the post-operative stage.
- Pruritus: Itching, typically around the nose or torso.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Respiratory anxiety in the absence of resuscitative equipment.
- Concurrent usage of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (danger of serotonin syndrome).
- Myasthenia gravis (due to muscle-relaxing interactions).
Regulation and Storage in the UK
