Fentanyl is a cornerstone of modern anaesthesia. It is utilized as an analgesic supplement during the induction and upkeep of general anaesthesia. It helps blunt the body's physiological "stress response" to intubation and surgical incision.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl might be administered in little, titrated boluses to handle instant post-surgical pain 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 permits more foreseeable "wake-up" tests compared to drugs like morphine.
Table 2: Clinical Application Summary
| Application | Function of Fentanyl |
|---|---|
| Pre-medication | To offer sedation and analgesia before transferring to theatre. |
| Induction | To comply with induction agents (like Propofol) for a smooth shift to unconsciousness. |
| Upkeep | To manage the surgical discomfort stimulus during the treatment. |
| Analgesic Supplement | Used in local anaesthesia (like epidurals) to boost discomfort relief. |
Mechanism of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. click here ascending pain paths, changing the understanding of and response to pain. It also increases the discomfort limit.
- Onset of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Duration: 30-- 60 minutes (making it extremely titratable).
- Metabolism: Primarily in the liver via the CYP3A4 enzyme.
- Excretion: Mostly by means of the kidneys.
Due to the fact that fentanyl is highly lipid-soluble, it crosses the blood-brain barrier almost immediately, which describes why the analgesic impact is felt a lot faster than with morphine or oxycodone.

- Nausea and Vomiting: Common in the post-operative phase.
- Pruritus: Itching, often 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 use of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (risk of serotonin syndrome).
- Myasthenia gravis (due to muscle-relaxing interactions).
Regulation and Storage in the UK
