- decreased level of consciousness
- constipation
What is a typical and high dose of Morphine?
typical: 1-4mg
high dose: 10mg
How much Hydropmorphone is equivalent to 10mg IV Morphine?
1.5mg
What is a typical and high dose of Hydromorphone?
typical: 0.2-0.4
high dose: 4mg
What is a typical and high dose of Fentanyl?
typical: 25-100mcg IV

How much Fentanyl is equivalent to 10mg Morphine?
200 mcg
Which IV opioid is most likely to cause hypotension?
Morphie
What IV opioid has active metabolites that accumulate with renal dysfunction?
Morphine
What are the options for non-opioid analgesics?
- Acetaminophen
- Ketolorac (Toradol)
- Ketamine
What opioid is only used for post-operative shivering?
Meperidine DEMEROL
What are risks with Meperidine DEMEROL?
- neurotoxic metabolite-induced delirium, tremor, seizures
- high risk of serotonin syndromes with SSRIs and MAOIs
Why is Ketamine for sedation not the best option in patients with high BP/HR?
can act as a sympathomimetic and lead to increased BP and HR

What is the dosing for APAP?
650-1000mg Q6H prn mild pain
What is dosing for Ketorolac?
15-30mg IV Q6H max. 5 days
What patients should Ketorolac be used with caution in?
increased risk of GI bleed or renal impairment
What is dosing for Ketamine as an analgesic?
0.5mg/kg IV x 1,
then 0.05-0.25 mcg/kg.h
What is dosing for ketamine for sedation?
2.5 mg/kg/h
What reactions are at increased risk of occurring when using sedation doses of ketamine?
emergence delirium and hallucinations
What agents are locally infused anesthetics?
- Bupivacaine
- Lidocaine
What is dosing for Gabapentin?
100mg PO TID
max 3600mg (requires renal adjustment)
What is dosing for Carbamazepine?
50-100mg PO TID
max dose 1200mg
What kind of benzo dosing is associated with increased delirium?
PRN bolus dosing
All benzos are metabolized by what?
liver; reduced clearance in hepatic patients
Which benzos have metabolites that accumulate in renal impairment?
- Diazepam
- Midazolam
- Lorazepam (PROPYLENE GLYCOL)
What is dosing for Midazolam?
0.02-0.1mg/kg/h
What is dosing for Lorazepam?
infusion: 0.01-0.1 mg/kg/h
PRN: 0.02-0.06 mg/kg Q2H
What does propylene glycol accumulation with high doses of Lorazepam lead to?
- acute tubular necrosis
- lactic acidosis
What are SEs with benzos?
- respiratory depression
- hypotension
What sedatives require the patient to be intubated?
- Midazolam
- Propofol
What is dosing for Propofol?
5-50mcg/kg/min
What are SEs of Propofol?
- severe hypotension
- respiratory depression
- increased TGs/ pancreatitis
- PRIS
What is PRIS?
Propofol Infusion Symdrome:
life-threatening syndrome resulting in metabolic acidosis, rhabdomyolysis, myocardial failure, fatal arrhythmias, AKI, hyperkalemia, and liver dysfunction
What dosage of Propofol is PRIS most associated with?
- > 70mcg/kg/min
- > 48h
What is the role of Dexedetomidine PRECEDEX in sedation?
- light sedation in non-intubated patients
- associated with less delirium than benzos
What are SEs with Dexedetomidine PRECEDEX?
- hypotension
- bradycardia
What is dosing of Dexedetomidine PRECEDEX?
0.2-1.5 mcg/kg/h
What agents are used for ICU delirium?

- EPS
- QTc prolongation
- fatal arrhythmias
What are SEs with atypical antipsychotics?
risk of QTc prolongation
How do we prevent ICU delirium?
Assess, prevent, manage pain
Both SAT and SBT (sedation vacay)
Choice of analgesia and sedation
Delirium assess, prevent, manage
Early mobility
Family engagement
