Lidocaine, Esmolol, or Placebo to Relieve IV Propofol Pain
Study Details
Study Description
Brief Summary
The primary hypothesis is that esmolol and lidocaine, when given without the use of a tourniquet, provide relief of propofol injection pain that is superior to placebo when assessed using the propofol pain scoring tool

Phase 2/Phase 3 |
Detailed Description
The study will include three arms: lidocaine, esmolol, and placebo. Eligible patients will be 18-60 years old, ASA physical status 1-3, and scheduled for an elective surgical procedure. Patients will be randomized to receive lidocaine, esmolol, or placebo. Both the patients and the administering/observing providers will be blinded to the study drug or placebo being administered

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Active Comparator: Lidocaine 1 mg/kg lidocaine to a max of 100 mg |
Drug: Lidocaine
1 mg/kg lidocaine to a max of 100 mg administered approximately 30 seconds prior to the administration of propofol, with pain score obtained before the propofol is administered.
|
Active Comparator: Esmolol 0.5 mg/kg esmolol to a max of 50 mg |
Drug: Esmolol
0.5 mg/kg esmolol to a max of 50mg administered approximately 30 seconds prior to the administration of propofol, with pain score obtained before the propofol is administered.
|
Placebo Comparator: Placebo Saline water |
Other: Placebo
saline water administered approximately 30 seconds prior to the administration of propofol, with pain score obtained before the propofol is administered.

Outcome Measures
Primary Outcome Measures
- Pain with propofol injection [following administration of a sub-induction dose of propofol, 0.5 mg/kg up to 50 mg, just prior to full induction]
the proportion of patients with pain using a pain scoring system previously used by studies looking at various remedies to decrease propofol injection pain In this scoring system, patients are observed and their responses and behaviors are rated according a specific rubric (Table 1)
Secondary Outcome Measures
- Heart rate [vital signs each minute for the first 10 minutes following induction]
- Blood pressure [vital signs each minute for the first 10 minutes following induction]
- Oxygen saturation [vital signs each minute for the first 10 minutes following induction]
