What is the recommended dosing for Vecuronium (Pancuronium derivative)

From the Guidelines

Vecuronium should be administered at an initial intubating dose of 0.1 mg/kg IV, with a continuous infusion of 0.8–2 μg/kg/min for maintenance, as this dosing regimen is recommended for effective neuromuscular blockade in critically ill patients 1.

Key Considerations for Vecuronium Dosing

• The initial bolus dose of vecuronium produces blockade within 60–90 seconds, with a duration of action of 25–40 minutes 1.
• Continuous infusion rates may need to be adjusted based on the degree of blockade desired and the patient's renal and hepatic function.
• Patients with renal impairment may require decreased doses due to reduced clearance of the drug 1.
• Monitoring with a peripheral nerve stimulator is crucial to assess the degree of neuromuscular blockade and adjust the infusion rate accordingly.

Important Safety Considerations

• Vecuronium should only be administered by clinicians trained in airway management, with full resuscitation equipment immediately available.
• The medication works by competitively binding to acetylcholine receptors at the neuromuscular junction, preventing muscle contraction.
• Unlike pancuronium, vecuronium has minimal cardiovascular effects, making it suitable for hemodynamically unstable patients or those with cardiovascular disease.

Special Populations

• Patients with hepatic insufficiency may require decreased doses due to impaired drug metabolism 1.
• Patients with renal failure will have decreased drug requirements due to reduced renal excretion of the drug 1.

From the FDA Drug Label

DOSAGE & ADMINISTRATION Vecuronium bromide for injection is for intravenous use only. The recommended initial dose of vecuronium bromide is 0. 08 to 0.1 mg/kg (1.4 to 1.75 times the ED90) given as an intravenous bolus injection. During prolonged surgical procedures, maintenance doses of 0.01 to 0. 015 mg/kg of vecuronium bromide are recommended; Use by Continuous Infusion After an intubating dose of 80 to 100 mcg/kg, a continuous infusion of 1 mcg/kg/min can be initiated approximately 20-40 min later The infusion of vecuronium should be individualized for each patient The rate of administration should be adjusted according to the patient’s twitch response as determined by peripheral nerve stimulation. An initial rate of 1 mcg/kg/min is recommended, with the rate of the infusion adjusted thereafter to maintain a 90% suppression of twitch response.

The recommended dosing for Vecuronium is as follows:

• Initial dose: 0.08 to 0.1 mg/kg given as an intravenous bolus injection
• Maintenance doses: 0.01 to 0.015 mg/kg during prolonged surgical procedures
• Continuous infusion: 1 mcg/kg/min, initiated 20-40 minutes after an intubating dose of 80 to 100 mcg/kg, with an initial rate adjusted to maintain a 90% suppression of twitch response 2

From the Research

Vecuronium Dosing

• The recommended dosing for Vecuronium, a Pancuronium derivative, varies depending on the specific use case and patient population.
• For rapid tracheal intubation, a dose of 0.1 mg/kg has been used, with satisfactory conditions for intubation developing in 156 +/- 12 seconds 3.
• A "priming" dose of 0.015 mg/kg, followed 6 minutes later by an "intubating" dose of 0.050 mg/kg, has also been used to decrease intubation time to 61 +/- 3 seconds 3.
• Other studies have used doses of 0.10 mg/kg, 0.15 mg/kg, or 0.20 mg/kg for intubation, with excellent intubating conditions achieved in 60 seconds after induction of anesthesia 4.
• In elderly patients, a dose of 0.1 mg/kg has been used, with intubation time found to be shorter with rocuronium compared to vecuronium and cisatracurium 5.
• For prolonged neuromuscular blockade, a large dose of 0.3 mg/kg has been compared to pancuronium 0.1 mg/kg, with vecuronium showing more favorable neuromuscular blocking effects 6.
• In patients with myasthenia gravis, reduced doses of vecuronium (0.02-0.04 mg/kg) have been used, with careful neuromuscular monitoring to ensure safe use 7.
