local anesthetics Flashcards
describe local anesthesia
- produces local loss of sensation and motor activity
- prevents cells from responding to pain and stimulation impulse
what order do you lose your shit with local anesthetics
- temp
- touch
- proprioception
- muscle tone
and they come back in the opposite way i think
give an example of a local anesthetic
lidocaine
any of the caines also
describe the action of local anesthetics
blocks nerve conduction, blocking pain signal conduction
what are local anesthetics used for
varying routes for local anesthesia
what are some adverse effects of local anesthetics
- vary based on route
- increased effect with epinephrine
- burning or pain at application site
- N/V
- shivering
what are some contraindications of local anesthetics
cardiac abnormalities
describe topical local anesthetics
ointment or drop to skin/mucous membranes
- sunburn cream
- sore throat spray
descibr field block
barrier around surgical site
used for tooth extraction
describe nerve block
blocking large nerve impulses
- epidural
- spinal block
what are some nursing considerations for local anesthetics
- topical applicatio works in 20mins
- if using a caine patch, apply to most painful area after removing old patch and washing site
- do not use heat pad over caine patch site
- monitor EKG/cardiac assessment for larger doses
- ensure patient safety if nerve block used
describe patient education for local anesthetics
- report unrelieved pain
- report tachycardia or anxiety
- is uding patch; remove old patch, cleanse site, and apply new patch
- apply patch to most painful site
- fall risk
the rational for withholding food and drink after local anesthetic to mouth or throat is to:
- prevent aspiration
- prevent infection
- minimize hypersensitivity
- enhance pain control
- prevent aspiration
until your gag reflex has returned you are unable to protect your airway and are at an increased risk for aspiration
