Study Details

Study Description

Brief Summary

This study will collect data from multiple academic institutions. The primary objective for part A of this study is to determine the impact of anesthetic injection rate and temperature on pain perception during dermatologic procedures, and the objective for the part B of this study is to determine if buffering of the anesthetic solution alters pain perception.

This study is a pilot study designed to determine feasibility of these procedures.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Slow, Room Temperature

In Part A, subject will be randomized to receive an injection of lidocaine that is slow at room temperature, rapid at room temperature, slow at warm temperature, or rapid at warm temperature.

Procedure: Slow, Room Temperature Injection
The room temperature local anesthetic agent will be administered by slow infiltration.

Drug: Lidocaine
Injectable lidocaine solution (Lidocaine Hydrochloride and Epinephrine)

Drug: Buffer
Sodium Bicarbonate

Experimental: Rapid, Room Temperature

In Part A, subject will be randomized to receive an injection of lidocaine that is slow at room temperature, rapid at room temperature, slow at warm temperature, or rapid at warm temperature.

Procedure: Rapid, Room Temperature Injection
The room temperature local anesthetic agent will be administered by rapid infiltration.

Drug: Lidocaine
Injectable lidocaine solution (Lidocaine Hydrochloride and Epinephrine)

Drug: Buffer
Sodium Bicarbonate

Experimental: Slow, Warmed

In Part A, subject will be randomized to receive an injection of lidocaine that is slow at room temperature, rapid at room temperature, slow at warm temperature, or rapid at warm temperature.

Procedure: Slow, Warm Temperature Injection
The warmed local anesthetic agent will be administered by slow infiltration.

Drug: Lidocaine
Injectable lidocaine solution (Lidocaine Hydrochloride and Epinephrine)

Drug: Buffer
Sodium Bicarbonate

Experimental: Rapid, Warmed

In Part A, subject will be randomized to receive an injection of lidocaine that is slow at room temperature, rapid at room temperature, slow at warm temperature, or rapid at warm temperature.

Procedure: Rapid, Warm Temperature Injection
The warmed local anesthetic agent will be administered by rapid infiltration.

Drug: Lidocaine
Injectable lidocaine solution (Lidocaine Hydrochloride and Epinephrine)

Drug: Buffer
Sodium Bicarbonate

Experimental: Buffered

In Part B, subject will be randomized to receive an injection of lidocaine that is buffered or non-buffered.

Procedure: Buffered Injection
One side of the body will be randomized to receive an injection of the buffered agent, while the contralateral side will be assigned to receive an injection of the unbuffered anesthetic agent.

Drug: Lidocaine
Injectable lidocaine solution (Lidocaine Hydrochloride and Epinephrine)

Drug: Buffer
Sodium Bicarbonate

Placebo Comparator: Non-Buffered

In Part B, subject will be randomized to receive an injection of lidocaine that is buffered or non-buffered.

Procedure: Non-Buffered Injection
One side of the body will be randomized to receive an injection of the buffered agent, while the contralateral side will be assigned to receive an injection of the unbuffered anesthetic agent.

Drug: Lidocaine
Injectable lidocaine solution (Lidocaine Hydrochloride and Epinephrine)

Outcome Measures

Primary Outcome Measures

  1. Pain on a Visual Analog Scale (VAS) [intraoperative]

    Subjects will rate the pain VAS score immediately after the needle is withdrawn. They will be asked to rate the pain of the injection of the solution. VAS pain scale is rated on a 10 cm scale with 0 cm being no pain and 10 cm being extremely painful.
