About this study

Official title: The Efficacy of the Eutectic Mixture of Local Anesthetics (EMLA) Cream Versus the Synera Patch for Pain Reduction During Venipuncture in Children

This study compares the efficacy of the Synera patch with Eutectic Mixture of Local Anesthetics (EMLA) as a topical anesthetic for venipuncture in pediatric patients.

Read the detailed description

Venipunctures are common and necessary components of pediatric health care. Unfortunately, many children have "needle phobia" and even a simple procedure, such as a venipuncture, can cause significant stress and anxiety to the patient and the parents involved. Studies have shown that needles are the worst part of hospital/healthcare related visits for children.

The Synera patch uses a controlled heating system to transcutaneously deliver a lidocaine/tetracaine mixture for analgesic effect. No published studies compare the efficacy of the Synera patch with other topical anesthetics in children. The objective of this study is to compare the efficacy of the Synera patch applied for 20 minutes with the efficacy of EMLA Cream applied for 60 minutes in reducing pain associated with venipunctures in children.

Patients, 4-12 years old children requiring venipunctures in clinics, were randomized to receive Synera for 20 minutes or EMLA for 60 minutes. A blinded observer recorded pain scores using a numerical rating scale (NRS). Child and parent assessed pain with the Wong-Baker FACES Scale and the NRS, respectively. The primary outcome was the number of subjects reporting "no pain". Secondary outcomes were parent and observer measures of the child's pain and the presence of skin reactions.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Participants Self-rating of Pain Using the Wong-Baker FACES Pain Rating Scale.

    Participants were asked to report their level of pain using a 6-point Wong-Baker FACES Pain Rating Scale ranging from 0, "no pain," to 5, "the most pain you can have." The Wong-Baker FACES Pain Rating Scale is a validated tool for measuring pain in patients as young as 3 years old. A FACES pain score less than or equal to 2 is considered no pain to mild pain, and is clinically acceptable. Studies have shown average FACES pain scores for children receiving vascular access with placebo to be 2.2 to 3.5.

    Measured: immediately after completion of venipuncture

Secondary outcomes (4)
  1. Parent Rating of Child's Pain Using a 6-point NRS

    The Numerical Rating Scale (NRS) is a 6-point rating scale where 0= no pain and 5 = worst pain. Parents reported their own subjective evaluation of participants pain level. Each participant had only one parental assessment. Total number of parental assessment for each pain level on the 6-point NRS is reported as total number of participants experiencing that pain level.

    Measured: immediately after venipuncture is completed

  2. Blinded Observer's Subjective Ratings of Participants' Pain Level at Tourniquet Placement, Using a 6-point NRS

    The NRS (Numerical Rating Scale) is a 6-point rating scale where 0= no pain and 5 = worst pain. Blinded observers reported their own subjective evaluation of the level of pain experienced by the participants at tourniquet placement. Total number of participants subjectively evaluated as experiencing each pain level is reported.

    Measured: before venipuncture

  3. Blinded Observer's Subjective Ratings of the Participant's Pain Level at Needle Insertion, Using a 6-point NRS

    The NRS (Numerical Rating Scale) is a 6-point rating scale where 0= no pain and 5 = worst pain. Blinded observers reported their own subjective evaluation of the level of pain experienced by the participants at needle insertion. Total number of participants subjectively evaluated as experiencing each pain level is reported.

    Measured: during needle insertion

  4. Blinded Observer's Subjective Ratings of the Participant's Pain Level at 5 Minutes Post Venipuncture Procedure, Using a 6-point NRS

    The NRS (Numerical Rating Scale) is a 6-point rating scale where 0= no pain and 5 = worst pain. Blinded observers reported their own subjective evaluation of the level of pain participants were experiencing 5 minutes after the venipuncture was completed. Total number of participants subjectively evaluated as experiencing each pain level is reported.

    Measured: 5 minutes post venipuncture
