54
Q

Succinylcholine (Anectine) considerations:

who would you give to

who would you avoid it in

A

Give:

  • RSI: 1.5 mg/kg

Avoid:

  • peds < 5 yrs (risk for DMD)
  • hyperK+ patients
  • can give in renal pts if their K+ is normal (nagelhout)
  • lower motor neuron disease (upregulation of nAChRs) = give less or avoid in all of them except for MG
  • MG pts are resistant to succ bc they have less nAChRs (antibodies blocking the reeceptor)
  • lower PChE activity: advanced liver dz, age, malnutrition, pregnancy, burns, PO laxatives, MAOIs, echothiopate, cytotoxic drugs, anticholinesterase drugs

don’t have to avoid, but need much lower doses of nondepolarizers for all of them

55
Q

Succinylcholine (Anectine) considerations:

side effects

A
  • neuro: ↑ ICP/IOP
  • CV: tachycardia, but could cause sudden bradycardia in peds (or repeat doses in adults), falyar said bradycardia/junctional/sinus arrest
  • labs: intubating dose increases K+ by 0.5-1 mEQ/dL
  • GI/GU: ↑ gastric pressure/lower esophageal pressures, myoglobinuria
  • MSK: myalgia, masseter spasm - could be d/t MH or inadequate dosing
  • decreased synth of PChE in hepatitis/cirrhosis
  • dibucaine number
    • normal = 80% of PChE was inhibited by dibucaine
    • 40-60 = prolongs block 1.5-2x longer
    • <30 = prolongs block for 4-8 hrs!
56
Q

Glycopyrrolate Dose

A

5-10 mcg/kg

= .005 - 0.01 mg/kg

so just stick to 0.01 mg/kg

(other chart says 0.01-0.02 mg/kg)

“glyco-pyro, starts with 5 yo”

57
Q

glycopyrrolate syringe

A

3 or 5 mL

58

A

onset < 1 minute

peak 5 minute

glyco and neostigmine are slower onset, but sustained effect

59
Q

Glycopyrrolate T1/2

A

Nagelhout: less than 10% of drug is in the serum after 5 minutes

85% of IV dose is excreted in urine within 48 hrs

60
Q

Glycopyrrolate metabolism

A

Nagelhout: excreted in the feces/urine, primarily as unchanged drug

(makes sense bc highly charged)

“small amts are metabolized into inactive metabolites”

61

(another source says 6-16 min)

101

A

5 mL = 10 mg

(might need 2 vials)

example calculation 70 kg person = 7 mg, or 14 mg

102
Q

Cisatricurium metabolism

A

Hoffman Elimination in plasma and tissues

pH and temperature dependent

Hoffman accounts for 77% of elim of cis, and the other 23% is from plasma esterases

103
Q

Cisatracurium considerations

A

Laudanosine liberation (although 1/5 as much as atracurium). This means that the pt is at risk for convulsions, bc it crosses the BBB!

Laudanosine requires liver for metabolism, excreted in the bile and urine (so biliary obstructed pts will have an issue with this)

This is more a consideration for atracurium tbh.
