2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl may be administered in small, titrated boluses to handle instant 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 frequently used as an infusion to offer constant analgesia for patients who are mechanically aerated. Its short half-life enables more predictable “wake-up” tests compared to drugs like morphine.

Application
Role of Fentanyl
Pre-medication
To provide sedation and analgesia before moving to theatre.

To cooperate with induction agents (like Propofol) for a smooth shift to unconsciousness.
Maintenance
To handle the surgical discomfort stimulus during the treatment.

System of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. Fentanyl Citrate Injection Side Effects UK ascending discomfort pathways, changing the perception of and response to discomfort. It also increases the pain threshold.
- Start of Action: 1— 2 minutes (Intravenous).
- Peak Effect: 3— 5 minutes.
- Period: 30— 60 minutes (making it extremely titratable).
- Metabolism: Primarily in the liver by means of the CYP3A4 enzyme.
- Excretion: Mostly through the kidneys.
Because fentanyl is highly lipid-soluble, it crosses the blood-brain barrier almost instantly, which explains why the analgesic result is felt so much faster than with morphine or oxycodone.

Security and Side Effects

Common Side Effects:
- Respiratory Depression: The most major threat; it reduces the drive to breathe.
- Bradycardia: A slow heart rate.
- Hypotension: Low high blood pressure.
- Muscle Rigidity: Specifically “wood chest syndrome,” where the chest wall ends up being too stiff to aerate quickly (typically takes place with high-dose rapid IV administration).
- Nausea and Vomiting: Common in the post-operative phase.
- Pruritus: Itching, typically around the nose or torso.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Breathing depression in the lack of resuscitative devices.
- Concurrent use of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (danger of serotonin syndrome).
Myasthenia gravis (due to muscle-relaxing interactions).

Policy and Storage in the UK
