3. Intensive Care (ICU)
In the Intensive Care Unit, fentanyl is often utilized as an infusion to provide continuous analgesia for clients who are mechanically aerated. Its brief half-life permits more predictable "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 shift to unconsciousness. |
| Maintenance | To handle the surgical discomfort stimulus during the procedure. |
| Analgesic Supplement | Utilized in regional anaesthesia (like epidurals) to boost pain relief. |
System of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding hinders ascending pain paths, changing the understanding of and response to pain. It likewise increases the pain limit.
- Beginning of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Period: 30-- 60 minutes (making it highly titratable).
- Metabolism: Primarily in the liver through the CYP3A4 enzyme.
- Excretion: Mostly via the kidneys.
Since fentanyl is extremely lipid-soluble, it crosses the blood-brain barrier practically immediately, which discusses why the analgesic result is felt a lot faster than with morphine or oxycodone.
Safety and Side Effects
Similar to all powerful opioids, fentanyl citrate brings a threat of substantial negative effects, especially associating with the respiratory and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most severe danger; it minimizes the drive to breathe.
- Bradycardia: A slow heart rate.
- Hypotension: Low high blood pressure.
- Muscle Rigidity: Specifically "wood chest syndrome," where the chest wall becomes too stiff to ventilate easily (generally accompanies high-dose fast IV administration).
- Nausea and Vomiting: Common in the post-operative stage.
- Pruritus: Itching, often around the nose or torso.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Respiratory depression in the absence of resuscitative equipment.
- Concurrent use of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (danger of serotonin syndrome).
- Myasthenia gravis (due to muscle-relaxing interactions).
Guideline and Storage in the UK
In the United Kingdom, fentanyl citrate is strictly regulated to avoid diversion and misuse.
- Storage: It must be kept in a locked "Controlled Drugs" (CD) cupboard that satisfies the British Standard for security.
- Record Keeping: Every dose administered need to be recorded in a Controlled Drugs Register, signed by two competent health care specialists (generally a medical professional and a nurse, or two nurses).
