1. Anaesthesia
Fentanyl is a cornerstone of modern anaesthesia. It is used as an analgesic supplement throughout the induction and upkeep of general anaesthesia. It assists blunt the body's physiological "stress reaction" to intubation and surgical cut.
2. Post-operative Recovery

3. Intensive Care (ICU)
In the Intensive Care Unit, fentanyl is often utilized as an infusion to offer continuous analgesia for patients who are mechanically ventilated. Its short 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 offer sedation and analgesia before relocating to theatre. |
| Induction | To comply with induction agents (like Propofol) for a smooth transition to unconsciousness. |
| Maintenance | To manage the surgical pain stimulus during the procedure. |
| Analgesic Supplement | Utilized in local anaesthesia (like epidurals) to enhance discomfort relief. |
Mechanism of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding inhibits rising pain paths, altering the perception of and response to discomfort. It likewise increases the pain limit.
- Beginning of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Duration: 30-- 60 minutes (making it highly titratable).
- Metabolism: Primarily in the liver by means of the CYP3A4 enzyme.
- Excretion: Mostly via the kidneys.
Since fentanyl is highly lipid-soluble, it crosses the blood-brain barrier almost instantly, which discusses why the analgesic effect is felt so much faster than with morphine or oxycodone.
Safety and Side Effects
Just like all powerful opioids, fentanyl citrate brings a risk of considerable side results, particularly relating to the respiratory and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most serious danger; it decreases the drive to breathe.
- Bradycardia: A sluggish heart rate.
- Hypotension: Low high blood pressure.
- Muscle Rigidity: Specifically "wooden chest syndrome," where the chest wall becomes too stiff to ventilate quickly (usually accompanies high-dose quick IV administration).
- Nausea and Vomiting: Common in the post-operative stage.
- Pruritus: Itching, often around the nose or upper body.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Breathing depression in the lack of resuscitative equipment.
- Concurrent usage 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
In the United Kingdom, fentanyl citrate is strictly regulated to avoid diversion and misuse.
- Storage: It should be kept in a locked "Controlled Drugs" (CD) cabinet that satisfies the British Standard for security.
- Record Keeping: Every dose administered should be tape-recorded in a Controlled Drugs Register, signed by two certified health care specialists (generally a doctor and a nurse, or 2 nurses).
