Etomidate is a commonly used sedative during rapid sequence intubation (RSI). Septic patients have an increased risk of developing adrenal suppression, which has been associated with increased mortality in some studies. [16] Since etomidate affects cortisol production, its use in septic patients is controversial.
Can fish be sedated?
Fish display robust neuroendocrine and physiologic stress responses to noxious stimuli. Many anesthetic, sedative, or analgesic drugs used in other vertebrates reduce stress in fish, decrease handling trauma, minimize movement and physiologic changes in response to nociceptive stimuli, and can be used for euthanasia.
Where is benzocaine from?
Benzocaine is a chemical compound derived from para-aminobenzoic acid and ethanol. It is a white, odorless, crystalline powder. It acts on neuronal membranes and blocks nerve signals in the body.
