Administration Protocols In the UK, the administration of fentanyl citrate is strictly managed and normally performed by anaesthetists or trained specialists in controlled environments.
Dose Guidelines Dose needs to be horizontal and individualised based upon the patient's age, weight, physical status, underlying pathological condition, usage of other drugs, and the type of surgical treatment.
Low Dose (2 mcg/kg): Useful for small surgical procedures. Moderate Dose (2-- 20 mcg/kg): Used when surgery is more invasive; needs respiratory monitoring. High Dose (20-- 50 mcg/kg): Used throughout "worry-free" major surgical procedures (e.g., open-heart surgery) to secure the myocardium from the metabolic needs of stress.

Muscle Rigidity (Chest Wall Rigidity): High doses can make ventilation hard, needing making use of neuromuscular blocking agents. Nausea and Vomiting: Common in the postoperative duration. Hypotension: Although more steady than morphine, it can still happen, especially in hypovolaemic patients. Comparison with Other Opioids Clinicians often pick fentanyl over other opioids due to its specific pharmacokinetic profile.
