Is succinylcholine a anticholinergic?
No, succinylcholine is not an anticholinergic; it is a depolarizing neuromuscular blocker. It works by mimicking the action of acetylcholine at the neuromuscular junction, leading to muscle paralysis. Anticholinergics, on the other hand, inhibit the action of acetylcholine, typically used to reduce secretions or treat bradycardia. Therefore, succinylcholine and anticholinergics have opposing mechanisms of action.
Depolarizing muscle relaxant used in surgery?
I believe you're thinking of succinylcholine.
Which drug is a potent analgesic and a weak anesthetic Benzodiazepines Halothane nitrous oxide succinylcholine?

What is succinylcholine also known as?
This is a receptor agonist widely used as a muscle relaxant, both in people but also to induce paralysis in horses.It is also known as Anectine and Quelicin. In a hospital it is also known as "succs". It is also sometimes referred to as the poeple's medecine.
Succinylcholine acts as a depolarizing agent that prevents repolarization of the nerve. Name a site within the neuromuscular junction that might be affected to prevent the muscle contraction?
The nicotinic acetylcholine receptor (nAChR) on the post-synaptic muscle membrane is the site within the neuromuscular junction affected by succinylcholine. By binding to and activating these receptors, succinylcholine causes sustained depolarization and prevents repolarization, leading to muscle paralysis.
Why caution with succinylcholine during malignant hyperthermia?
Succinylcholine should be used with caution in patients with a history of malignant hyperthermia (MH) because it can trigger a hypermetabolic state in susceptible individuals. This drug can lead to increased calcium release from the sarcoplasmic reticulum in skeletal muscle, exacerbating the already heightened metabolic response associated with MH. The risk of severe complications, such as rhabdomyolysis, acidosis, and cardiac arrhythmias, necessitates careful monitoring and alternative agents during anesthesia in these patients. Therefore, avoiding succinylcholine is recommended in individuals known to be at risk for MH.
How long can IV succinylcholine chloride be unrefrigerated?
IV succinylcholine chloride should not be kept unrefrigerated for more than 24 hours for optimal stability. It is best to follow manufacturer recommendations and discard any unused portion after this time to ensure safety and efficacy.
How can you tell if you have malignant hyperthermia?
The only way to get malignant hyperthermia is (1) have the genes and (2) get a drug called succinylcholine, which is used to paralyze muscles for surgery.
Why do you not give succinylcholine to Lumbee Indians?
Due to how Succinylcholine metabolizes in Lumbee indians. It does not work as it should, immediately, but last longer in the body, causing paralysis a few hours to a few days later. It is a paralytic drug given pre-hospital care for head trauma with breathing issues, etc... Most paramedics know this information as it is one of the required drugs on the EMT-P formulary. Can not say that other medical staff will be as knowledgable.
What is the onset and duration of succinylcholine?
Onset of .5-1 min IV lasting 2-3 min. Onset of 2-3 min IM lasting 10-30 min
What blocks the action of acetylcholine?
Acetylcholine Inhibitors...That would include organophosphates, curare (or tubocuranine), succinylcholine, (a flaccid paralytic used in anesthesia to relax striated muscles for intubation), and various neurotoxins.
What is an appropriate initial dose of succinylcholine for a 168 pound patient undergoing a drug facilitated intubation procedure?
The appropriate initial dose of succinylcholine for a patient undergoing rapid sequence intubation is typically 1 to 1.5 mg/kg. For a 168-pound patient, which is approximately 76 kg, the initial dose would range from 76 to 114 mg. It's important to round the dose to the nearest available formulation, usually 100 mg in a clinical setting, and consider patient-specific factors such as medical history and potential contraindications.
