Propofol by infusion protocol for ED procedural sedation

Area of Science:

• Emergency Medicine
• Pharmacology
• Sedation and Analgesia

Background:

• Propofol is a widely used agent for procedural sedation and analgesia (PSA).
• Existing emergency department (ED) studies predominantly utilize bolus-dosed propofol protocols.
• This study investigates an alternative infusion-dosed propofol protocol for PSA in the ED.

Purpose of the Study:

• To evaluate the efficacy of infusion-dosed propofol for PSA in an academic ED.
• To assess the complication rate associated with this sedation protocol.
• To measure patient and caregiver satisfaction with infusion-dosed propofol.

Main Methods:

• A prospective, observational study design was employed in an academic ED setting.
• Propofol was administered via a predetermined infusion protocol at the physician's discretion.
• Key variables included adverse events, sedation and recovery times, and patient/provider satisfaction using a visual analog scale.

Main Results:

• Fifty patients underwent procedures with successful completion using infusion-dosed propofol.
• Average sedation and recovery times were rapid (4.6 and 8.2 minutes, respectively).
• Minor, reversible complications included respiratory depression (8 patients) and hypotension (6 patients); satisfaction scores were high, with 94% willing to use again.

Conclusions:

• Infusion-dosed propofol is an effective and safe option for PSA in the ED.
• The efficacy, satisfaction rates, and complication profile are comparable to bolus-dosed propofol protocols.
• This method offers a viable alternative for procedural sedation in emergency settings.
