Clubfoot Clinical Trial
Official title:
A Randomized, Comparison Study of L.M.X.4 Cream Versus J-Tip Needle-Free Injection System With Lidocaine in Children Undergoing In-Office Percutaneous Achilles Tenotomy for Clubfoot
Infants undergoing Ponseti treatment for idiopathic clubfoot often require percutaneous tendoachilles lengthening (TAL) after serial casting. This procedure is commonly performed in the office with a local anesthetic to avoid exposure to general anesthesia in the operating room. Topical anesthetic creams are commonly used to provide local analgesia for this procedure. The cream is applied to the infant's skin around the heel cord and requires 30-60 minutes to provide adequate analgesia, reaching a depth of up to 5 mm at maximum effect. Alternative to analgesic cream, the J-tip is a needle-free jet injection system that uses compressed CO2 instead of a needle to push 0.25 ml of lidocaine into the skin, providing local analgesia at the site of administration. This method likewise provides analgesia to the site of application at a depth of 5-8 mm, yet only takes approximately 1-2 minutes to achieve maximum effect. Aim 1: Determine which pain management method, L.M.X.4 Cream vs. J-tip 1% Xylocaine MPF Injection, provides the greatest pain relief to infants with clubfoot undergoing an in-office percutaneous TAL. Hypothesis: J-tip 1% Xylocaine MPF injection will provide equal or greater pain control when compared to L.M.X.4 cream in infants undergoing an in-office percutaneous TAL. Aim 2: Determine if there is a difference in the rate of adverse events between the two pain management methods, L.M.X.4 Cream vs. J-tip 1% Xylocaine MPF Injection. Hypothesis: J-tip 1% Xylocaine MPF injection will not be associated with an increased rate of adverse events in comparison to L.M.X.4 cream in infants undergoing an in-office percutaneous TAL. If J-tip Xylocaine MPF injection is shown to provide comparable or better pain control without an increase in adverse events, use of this needle-free injection system will decrease the overall length of visit and the cost of the procedure, thus increasing the quality, safety, and value.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | FLACC (Face, Legs, Activity, Cry, Consolability) Scale | The FLACC scale is used to assess pain in children. For this study, it will be administered by the Certified Child Life Specialist. The Face, Legs, Activity, Cry, Consolability (FLACC) scale is a measurement used to assess pain in children between the ages of 2 months and 7 years or individuals that are unable to communicate their pain. The scale is scored in a range of 0-10 with 0 representing no pain. Lower values represent lessening pain on the scale | Baseline, before cast placement to tenotomy procedure at the end of casting, approximately 10 weeks. | |
Primary | Pulse Oximetry | Pulse oximetry will be used to measure oxygen levels in the blood. An oxygen saturation level of 95 percent is considered normal | Baseline, before cast placement to tenotomy procedure at the end of casting, approximately 10 weeks. |
