1. Anaesthesia
Fentanyl is a cornerstone of modern-day anaesthesia. It is used as an analgesic supplement throughout the induction and upkeep of general anaesthesia. It helps blunt the body's physiological "stress response" to intubation and surgical cut.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl might be administered in little, titrated boluses to handle instant post-surgical pain before shifts 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 provide constant analgesia for clients 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 | Function of Fentanyl |
|---|---|
| Pre-medication | To provide sedation and analgesia before relocating to theatre. |
| Induction | To work together with induction agents (like Propofol) for a smooth transition to unconsciousness. |
| Upkeep | To manage the surgical pain stimulus throughout the treatment. |
| Analgesic Supplement | Utilized in regional anaesthesia (like epidurals) to enhance discomfort relief. |
System of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding inhibits rising pain pathways, altering the perception of and action to discomfort. It also increases the pain limit.
- Onset of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Period: 30-- 60 minutes (making it highly titratable).
- Metabolic process: Primarily in the liver through the CYP3A4 enzyme.
- Excretion: Mostly by means of the kidneys.
Because fentanyl is highly lipid-soluble, it crosses the blood-brain barrier practically quickly, which explains 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 considerable adverse effects, particularly connecting to the breathing and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most severe threat; it decreases the drive to breathe.
- Bradycardia: A sluggish heart rate.
- Hypotension: Low blood pressure.
- Muscle Rigidity: Specifically "wood chest syndrome," where the chest wall becomes too stiff to aerate quickly (typically takes place with high-dose rapid IV administration).
- Queasiness 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 lack of resuscitative devices.
- Concurrent use of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (risk 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 abuse.
- Storage: It should be kept in a locked "Controlled Drugs" (CD) cabinet that fulfills the British Standard for security.
- Record Keeping: Every dosage administered need to be tape-recorded in a Controlled Drugs Register, signed by 2 competent health care specialists (normally a medical professional and a nurse, or more nurses).
