The objective of our study is to determine if technique of lidocaine administration can decrease pain perception.

Hypothesis: There will be a significant difference in pain perception between patients who are given lidocaine on the skin surface prior to subcutaneous injection and patients who are given only subcutaneous injection by standard approach.

Primary Outcome Measures:
  • Pain assessment: overall [ Time Frame: post procedure (day 1) ] [ Designated as safety issue: No ]
    Visual analog scale (VAS), Revised Faces Pain Scale (RFPS), short form mcGill pain questionnaire (SF-MPQ)

Secondary Outcome Measures:
  • Pain Assessment: lidocaine injection [ Time Frame: post procedure (day 1) ] [ Designated as safety issue: No ]

  • Pain assessment: during procedure [ Time Frame: post procedure (day 1) ] [ Designated as safety issue: No ]

Estimated Enrollment: 490
Study Start Date: February 2011
Estimated Study Completion Date: December 2014
Estimated Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: lidocaine onto skin prior to lidocaine subcutaneous injection Drug: lidocaine
2ml 1% lidocaine placed onto surface of the skin immediately prior to 1% lidocaine subcutaneous injection
Active Comparator: lidocaine subcutaneous injection alone Drug: lidocaine
1% lidocaine subcutaneous injection alone

Detailed Description:

This is a single center prospective, randomized, blinded study assessing pain perception following 2 different lidocaine administration techniques in subjects who have planned medical procedures requiring local injection of lidocaine. Subjects will be approached and consented to participate in the study. They will be interviewed after the scheduled medical procedure to assess their pain using validated pain scores. An investigator who is not present for the procedure and blinded to the randomization will gather data regarding perceptions of pain from the entire procedure.

  • Adult patients refered to the University of Chicago Medical Centers Procedure Service for a planned medical procedure requiring local injection of lidocaine.
