What is neuromuscular blocking agents?
Most commonly used to paralyze the muscles of respiration during mechanical or cotrolled ventilation.
Do neuromuscular blocking agents have tranquilizing or analgesic properties?
No, so these agents should be used with general anesthesia
(ex. succinylcholine) act by causing a single surge of activity at the neuromuscular junction followed by a refractory period. May see spontaneous muschle movement followed by paralysis.
(ex.gallamine, pancuronium, atracurium besylate) act by blocking the receptors at the end plates, with no initial surge of activity seen. Nondepolarizing agents may be reversed with and anticholinesterase agent such as neostigmine or endrophonium (pretreat with atropine to counteract bradycardia)
What are the risk for neuromuscular blocking agents?
- Diffucutly assessing anesthetic depth (absence of jaw tone, reflexes)
- Don't use in animals with glaucoma hepatic or renal disease
Wake up patient by increasing CO2
Stimulate the intercostal in the diaphram expands the thorax and the negative pressure expands lungs
when breathing out the intercostal and lungs relax when the patient exhales
What is the normal ratio of inhalation/exhalation
