Arm Elevation for Prevention of Propofol Injection Pain
21. august 2026 opdateret af: Ferenc Rabai, Mayo Clinic
Efficacy of Passive Arm Elevation Versus Lidocaine Pretreatment for Prevention of Propofol Injection Pain: A Randomized, Controlled, Assessor Blinded, Pilot Feasibility Trial
The purpose of this research is to determine whether a simple technique, temporarily raising the arm during the injection of propofol (a commonly used medication for anesthesia), can reduce the pain that some people experience when the medication is given through an IV.
The study will compare this technique with the current standard approach of using lidocaine (a numbing medication), as well as a combination of both methods, to determine which approach is most effective at reducing injection pain.

Deltagergruppe / Arm |
Intervention / Behandling |
|---|---|
|
Eksperimentel: Arm Elevation Only
Participants receive saline pretreatment followed by propofol injection with passive elevation of the cannulated arm during propofol injection.
|
The cannulated arm is passively elevated approximately 60 to 90 degrees at the start of propofol injection and maintained briefly during and immediately after the injection before being returned to heart level.
Normal saline 0.9%, 2 mL, administered intravenously as sham lidocaine before propofol injection.
Standard LCT propofol administered as a standardized subanesthetic test dose, calculated as one-quarter of a 2.5 mg/kg induction dose using total body weight up to BMI 30 or ideal body weight above BMI 30, with a maximum study dose of 50 mg.
|
|
Aktiv komparator: Lidocaine Only
Participants receive lidocaine pretreatment followed by propofol injection while the cannulated arm remains neutral.
The non-IV arm is elevated as a sham maneuver.
|
Standard LCT propofol administered as a standardized subanesthetic test dose, calculated as one-quarter of a 2.5 mg/kg induction dose using total body weight up to BMI 30 or ideal body weight above BMI 30, with a maximum study dose of 50 mg.
Lidocaine 2%, 2 mL, administered intravenously before propofol injection.
The contralateral non-IV arm is elevated while the cannulated arm remains neutral.
|
|
Eksperimentel: Lidocaine Plus Arm Elevation
Participants receive lidocaine pretreatment followed by propofol injection with passive elevation of the cannulated arm during propofol injection.
|
The cannulated arm is passively elevated approximately 60 to 90 degrees at the start of propofol injection and maintained briefly during and immediately after the injection before being returned to heart level.
Standard LCT propofol administered as a standardized subanesthetic test dose, calculated as one-quarter of a 2.5 mg/kg induction dose using total body weight up to BMI 30 or ideal body weight above BMI 30, with a maximum study dose of 50 mg.
Lidocaine 2%, 2 mL, administered intravenously before propofol injection.
