Comparison of Synera Patch Versus LMX-4 Cream Versus Placebo Patch for Pain Reduction During Venipuncture in Children

2014-08-27 03:14:00 | BioPortfolio


The purpose of this study is to compare the effect of Synera patch versus LMX-4 cream and placebo on the level of pain, observed distress, difficulty of venipuncture and skin side effects in children undergoing intravenous blood draw in the emergency setting or the phlebotomy lab.


This study will compare the effectiveness of a patch applied for 30 minutes (Synera-lidocaine 70 mg/tetracaine 70 mg) with the effectiveness of a cream (LMX-4- 4% liposomal lidocaine) and a placebo patch applied for the same length of time in reducing pain due to needle sticks in children. One hundred fifty children and adolescents 5-17 years old admitted to emergency department or presenting to the phlebotomy lab. will be randomly placed in each group. Children will rate their level of pain using the Faces Pain Scale-Revised (FPS-R) before the medication is applied, after the medication is removed and after the needle stick. Parents and research observer will fill out the Observed Behavioral Distress (OBD) score. The phlebotomist will rate how difficult it was to perform the needle sticks. Any skin reaction seen by the investigator after the cream or patch is removed will be noted and compared among the three groups.

Subjects will be monitored from the time of enrollment to 5 minutes post phlebotomy.The Time Frame for which data will be presented is one (1) year.

Medical and Biotech [MESH] Definitions

An electrophysiologic technique for studying cells, cell membranes, and occasionally isolated organelles. All patch-clamp methods rely on a very high-resistance seal between a micropipette and a membrane; the seal is usually attained by gentle suction. The four most common variants include on-cell patch, inside-out patch, outside-out patch, and whole-cell clamp. Patch-clamp methods are commonly used to voltage clamp, that is control the voltage across the membrane and measure current flow, but current-clamp methods, in which the current is controlled and the voltage is measured, are also used.

A medicated adhesive patch placed on the skin to deliver a specific dose of medication into the bloodstream.

Skin tests in which the sensitizer is applied to a patch of cotton cloth or gauze held in place for approximately 48-72 hours. It is used for the elicitation of a contact hypersensitivity reaction.
