CH3 INTRAVENOUS DRUGS Flashcards
Bradycardia in children secondary to SUX is due to ?
muscaric stimulation in the sinus node of the heart
succinylcholine induced tachycardia in adult is secondary to?
histamine release
stimulation of autonomic ganglia
post junctional cardiac muscarinic receptors
side effect of sux?
hyperkalemia MH masseter spasm bradycardia myalgia
sux contraindicated for routine intubation in children?
true or false
true
orbicularis oculi is same with
laryngeal muscle
diaphragm
onset of NMB
most sensitive to least sensitive
larynx
diaphragm
OO
Adductus policis
RECOVERY NMB
first to last
larynx
oo=diaphragm
AP
volatile anesthetics
______ NMB and
_______ reversal agents
volatile anesthetics
potentiates NMB and
slowed / retard reversal agents
Maoi + meperidine /methadone/tramadol can cause
SEROTONIN SYNDROME agitation skeletal muscle rigidoty hyperpyrexia hypotension respi dec coma
Risk factor for emergence delirium
younger than 5
volatile=sevoflurane
ent optha cases
anxious parents
ETOMIDATE adverse effect
PONV - Highest /most common pain thrombophlebitis myoclonic movement hiccups
Pancuronium inc hr bp and co because?
moderate vagolytic effect
norepi release
dec reuptake of NE by adrenergic nerve
DANTROLENE
prevention of MH
control skeletal muscle spasticity
MOA
dec amount Calcium releases by the sarcoplasmic reticulum
DATROLENE most common SIDE EFFECT
muscle weakness -mc
nausea
diarrhea
blurred vision
iv diuresis ( mannitol to make iv) orally given - hepatitis and pleural effusion
DISULFIRAM
ALTERS metabolism of alcohol by irreversibly inactivating the enzyme aldehyde dehydrogenase
alcohol sensitivity up to 24 hrs
NALTREXONE
tx of alcohol addiction
combination with disulfiram
pure opiod anatgonist
prior to surgery:
inc requirement of opioids
STOPPED PRIOR TO OR
duration 24hrs
RSI NMB
sux
rocuronium
priming means
10 % of the intubating dose is followed 2-4 minutes by the 90 percent
NMB TERMINATES By
diffusiin of drug back inti the plasma
buprenorphine
agonist-antagonist
very strong affinity to mu receptor
slow dissociation from the receptor mlonger action
resistance to NALOXONE
vasodilator of pulmonary tree
no EFFECT IN systemic circulation
nitric oxide
sux metabolism? termination?
metabolism : psuedocholinesterase
termination:
diffusion to the extracellur fluid
DEXMEDTOMIDINE
Highly selective a2 agonist rapid onset 5min peak at 15 mins dec hr and co ( profouns cardiac arrest) respi mnimal
1-2 mcg/kg/min
mild tv change
no change in rr
greater
paco2 inc
FOSPROPOFOL
water soluble converted to propofol no pain no risk for hypertriglyceridemia pulmo embolism risk of sepsis
CHRONIC MSO4 develop tolerance after 2-3 weeks
analgesia
respi depressiin
nausea
euphoria
except
miosis and
constipation
CIMETIDINE impairs the metabolism of ?
LIDOCAINE
PROPANOLOL
DIAZEPAM
tx for organophosphate poisoning
atropine 2mg-6mg q5-10mins
pralidoxime 600mg
benzodiazepine
ALFENTANIL
less potent
more rapid onset
shorter duration
alfatenail ALang KWENTA
most to least potent ? fentanyl alfentanil sulfafentanyl remifentanil mso4
sufentanyl remifentnayl fentanyl alfafentanil mso4
BURN :
succinyl cause HYPERKALEMIA
first 24 hrs - safe
hyperkalemia peak at 7-10days starts at 2nd day
Clonidine dose for anti shivering
75mcg iv
Fentanyl
chest rigidity
treatment with
sux
nueroleptic malignant syndorme
like MH
PT TAKing antipsychotic drugs
dantrolene can be used
txt
amandatine
dantrolene
bromocriptine
MH triggerrd by
sux
volatile anesthetics
