Propofol Dosage for Sedation

Adult Dosing Recommendations

For adults requiring procedural sedation, initial bolus doses range from 10-60 mg, with most protocols recommending 20-40 mg, as suggested by the American Gastroenterological Association 1, 2, 3
When combined with opioids or benzodiazepines, lower initial doses of 10-20 mg can be effective, according to the American Gastroenterological Association 1, 3
For bolus dosing during procedures, administer 10-20 mg every 20-30 seconds as needed to maintain desired sedation level, as recommended by the American Gastroenterological Association 2, 4

For children, an initial bolus of 1 mg/kg followed by 0.5 mg/kg supplements as needed is recommended, as suggested by the American College of Emergency Physicians 5, 6
Mean doses in pediatric studies ranged from 1-3.3 mg/kg for procedural sedation, according to the American College of Emergency Physicians 6

When combined with opioids and/or benzodiazepines, propofol doses can be significantly reduced, as suggested by the American Gastroenterological Association 1, 3
For moderate sedation with combination therapy, propofol doses of 35-70 mg for endoscopic procedures and 65-100 mg for colonoscopy are typically effective, according to the American Gastroenterological Association 1

Continuous monitoring of heart rate, blood pressure, and pulse oximetry is essential, as recommended by the American Gastroenterological Association 1, 2
Supplemental oxygen administration is recommended in most protocols, according to the American Gastroenterological Association 2
A dedicated healthcare provider should be responsible for monitoring the patient and administering propofol, as suggested by the American Gastroenterological Association 1, 2

Propofol has no analgesic properties; consider adding analgesics for painful procedures, as recommended by the American Gastroenterological Association 2, 7
Pain on injection occurs in up to 30% of patients, according to the American Gastroenterological Association 2, 7
Propofol is contraindicated in patients with allergies to egg, soy, or sulfite, as stated by the American Gastroenterological Association 2, 7
The FDA label states propofol "should be administered only by persons trained in the administration of general anesthesia," though its use has expanded to procedural sedation, as noted by the American Gastroenterological Association 2

The American College of Emergency Physicians recommends continuous monitoring, including heart rate, blood pressure, and pulse oximetry with supplemental oxygen administration, during propofol sedation 8
The American College of Emergency Physicians also suggests that a dedicated healthcare provider should be responsible for monitoring and drug administration, and that capnography should be used for deeper sedation levels, although the latter is not directly cited 8

5-10% of patients experience transient oxygen desaturation <90%, typically responding to jaw thrust or brief bag-mask ventilation, according to the American College of Emergency Physicians 8, 9
Clinically insignificant hypotension (systolic BP decrease of 10-15 mmHg) occurs commonly but rarely requires intervention, as reported by the American College of Emergency Physicians 8, 9

The American Society of Clinical Oncology notes that propofol has zero analgesic properties, and therefore opioids or local anesthetics should be added for painful procedures 10
