PROPOFOL:
Class
:
General Anesthetic
Indications
:
Induction of anesthesia in patients ≥3 years of age; maintenance of anesthesia in
patients >2 months of age; in adults, for monitored anesthesia care sedation during procedures;
sedation in intubated, mechanically-ventilated ICU patients, postoperative antiemetic; refractory
delirium tremens.
Available dosage form in the hospital
: AMP (1%, 10%), 20MG / 1 ML 50ML VIAL
Dosage
:
Dosage must be individualized based on total body weight and titrated to the desired clinical effect.
Wait at least 3-5 minutes between dosage adjustments to clinically assess drug effects. Smaller doses
are required when used with opioids. The following are general dosing guidelines (see “Abbreviations”
section in front section for explanation of ASA-PS classes):
-General anesthesia: Note: Increase dose in patients with chronic alcoholism (Fassoulaki, 1993);
decrease dose with acutely intoxicated (alcoholic) patients.
-Induction:
-Healthy adults, ASA-PS 1 or 2, <55 years: I.V.: 2-2.5 mg/kg (~40 mg every 10 seconds until onset of
induction)
-Debilitated, ASA-PS 3 or 4: Refer to geriatric dosing.
-Maintenance:
-Healthy adults, ASA-PS 1 or 2, <55 years:
-I.V. infusion: Initial: 100-200 mcg/kg/minute (or 6-12 mg/kg/hour) for 10-15 minutes; usual
maintenance infusion rate: 50-100 mcg/kg/minute (or 3-6 mg/kg/hour) to optimize recovery time.
-I.V. intermittent bolus: 25-50 mg increments as needed
-Debilitated, ASA-PS 3 or 4: I.V. Infusion: Refer to geriatric dosing.
-Monitored anesthesia care sedation:
-Healthy adults, ASA-PS 1 or 2, <55 years: Slow I.V. infusion: 100-150 mcg/kg/minute (or 6-9
mg/kg/hour) for 3-5 minutes or slow injection: 0.5 mg/kg over 3-5 minutes followed by I.V. infusion
of 25-75 mcg/kg/minute (or 1.5-4.5 mg/kg/hour) or incremental bolus doses: 10 mg or 20 mg
-Debilitated or ASA-PS 3 or 4 patients: Use 80% of healthy adult dose
-ICU sedation in intubated mechanically-ventilated patients: Avoid rapid bolus injection;
individualize dose and titrate to response.
-Continuous infusion: Initial: 5 mcg/kg/minute (or 0.3 mg/kg/
hour); increase by 5-10 mcg/kg/minute (or
0.3-0.6 mg/kg/hour) every 5-10 minutes until desired sedation level is achieved; usual maintenance: 5-
50 mcg/kg/minute (or 0.3-3 mg/kg/hour); reduce dose after adequate sedation established and adjust to
response (eg, evaluate frequently to use minimum dose for sedation). Daily interruption with retitration
or a light target level of sedation is recommended to minimize prolonged sedative effects (Barr, 2013).
-Elderly, debilitated, or ASA-PS 3 or 4 patients: Refer to geriatric dosing.
-Postoperative nausea and vomiting (PONV), rescue therapy (unlabeled use; Gan, 2007; Unlugenc,
2004): I.V.: 20 mg, may be repeated
-Refractory status epilepticus (unlabeled use): 1-2 mg/kg bolus (optional), then 33-167 mcg/kg/minute
(or 2-10 mg/kg/hour) (Claassen, 2002; Kälviäinen, 2007; Meierkord, 2010; Rossetti, 2004); titrate to
desired effect (eg, burst suppression on EEG). Note: Doses >83 mcg/kg/minute (or >5 mg/kg/hour)
may increase the risk of hypotension and propofol-related infusion syndrome (PRIS) especially if used
for >48 hours; consider alternative therapies to avoid the risk of PRIS in longer term propofol
infusions.
Geriatric
-General anesthesia: Note: Increase dose in patients with chronic alcoholism (Fassoulaki, 1993);
decrease dose with acutely intoxicated (alcoholic) patients.
-Induction: Elderly, debilitated, ASA-PS 3 or 4: I.V.: 1-1.5 mg/kg (~20 mg every 10 seconds until onset
of induction)
-Maintenance: Elderly, debilitated, ASA-PS 3 or 4: I.V. infusion: 50-100 mcg/kg/minute (or 3-6
mg/kg/
hour)
-Monitored anesthesia care sedation: Elderly, debilitated, ASA-PS 3 or 4: I.V.: Use 80% of healthy
adult dose
-ICU sedation in intubated mechanically-ventilated patients: Avoid rapid bolus injection;
individualize dose and titrate to response:
-Continuous infusion: Elderly, debilitated, ASA-PS 3 or 4: Use 80% of healthy adult dose; reduce dose
after adequate sedation established and adjust to response (eg, evaluate frequently to use minimum dose
for sedation). Daily interruption with retitration or a light target level of sedation is recommended to
minimize prolonged sedative effects (Barr, 2013).
Renal Impairment:
No dosage adjustment necessary.
Hepatic Impairment:
No dosage adjustment necessary
