  1. 1-0.3 mcg/kg/min
  2. 25-1 mcg/kg analgesia
58
Q

Alfentanil MOA

A 
opioid agonist (synthetic opioid)
less potent than fentanyl; shorter duration of action
59
Q

Alfentanil Vd

A

0.6L/kg

high fraction of unionized drug (gives rise to rapid onset)

60
Q

Alfentanil dosing

A

15 mcg/kg blunts stimulation of DL
150-300 mcg/kg IV – produces unconsciousness (induction)
combo with inhaled anesthetic 15-150 mcg/kg/hr

61
Q

Alfentanil CST

A

60 mins

62
Q

Butorphanol MOA

A

opioid agonist/antagonist
low affinity for mu receptor (antagonist)
moderate affinity for kappa receptor (partial agonist)

63
Q

Nalbuphine MOA

A

opioid agonist/antagonist
antagonism at mu receptor
agonism at kappa receptor

64
Q

Opioid receptor agonist

A

Receptors located in spine, brain and periphery
• Pre synaptic – inhibit release of acetylcholine,
dopamine, norepinephrine and Substance P
• Post synaptic – increased K+ conductance = decreased function
Opioid receptors are G protein-coupled receptors
• Principle effect is to decrease neurotransmission
• Mimic the actions of endogenous ligands
• Enkephalins, endorphins and dynorphins

65
Q

Mu1

A
  • Analgesia (supraspinal and spinal)
  • Euphoria
  • Miosis
  • Bradycardia
  • Urinary retention
66
Q

Mu2

A 
Analgesia (spinal)
Depression of ventilation
Physical dependence
Constipation
"CAVA"
67
Q

Kappa

A

Activation results in the inhibition of neurotransmitter release
• Analgesia (supraspinal and spinal)
• Dysphoria, sedation
• Miosis
• Diuresis
• Lesser extent - hypoventilation and high-intensity pain
• Agonist-antagonist often act principally on K receptors’
• Low abuse potential

68
Q

Acetaminophen MOA

A

Activation of serotonergic pathways
Antagonism of NMDA, substance P and nitric oxide pathways
nonselective cox inhibitor

69
Q

Ibuprofen MOA

A

non selective cox inhibitor

70
Q

Ketorolac MOA

A

non selective cox inhibitor

71
Q

Celecoxib MOA

A

selective cox 2 inhibitor

increased CV risk

72
Q

Acetaminophen DOSING

A

325-650 mg PO 4-6h
Do not exceed >4,000mg/24h
IV: 1,000mg Q6h

73
Q

Dexmedetomidine dosing

A 
0.5-2 mcg/kg (max dose 20 mcg) 
gtt 0.2-0.7 mcg/kg/hr
severe bradycardia
half life: 2hrs
Vd: 1.54 l/kg
74
Q

Dexmedetomidine moa

A

highly selective alpha 2 agonist (presynaptic receptor)

blunts central sympathetic response

75
Q

Ketorolac dosing

A

15 mg IV Q6hrs preop

76
Q

Celecoxib dosing

A

400 mg PO preop

200 mg BID x5 days post op

77
Q

Ibuprofen dosing

A

200-800 mg PO

78
Q

Ibuprofen dosing

A

200-800 mg PO

79
Q

NMDA antagonist

A

NMDA: N-methyl-D-aspartate, GPCR ionotropic glutamate receptor
NMDA antagonists bind to receptor and inhibit function of glutamate (endogenous excitatory neurotransmitter)

80
Q

GABA agonist

A

Gamma-aminobutyric acid, major inhibitory neurotransmitter in CNS
Endogenous GABA binds to receptor and exerts its effects on chloride ion channels to cause hyperpolarization of the cell
Propofol & Etomidate bind to alpha subunit on GABA receptor and allosterically promote the effect of endogenous GABA

81
Q

meperidine dosing

A

12.5 mg postop shivering

82
Q

meperidine Vd

A

2.6 L/kg

83
Q

remifentanil Vd

A
