Primary Outcome Measures:
  • FLACC: Face, Legs, Activity, Cry, and Consolability Pain Assessment Scale (FLACC) [ Time Frame: Admission into PACU ]
    FLACC: Face, Legs, Activity, Cry, and Consolability Pain Assessment Scale (FLACC), a five-item, three point scale that measures pain behavior on a scale of 0 - 2 which are summed to result in a total score of 0 - 10. Clinical judgment is used to interpret pain. The higher the score on the FLACC correlates with a higher pain score (0= no behaviors indicative of pain and 10= five behaviors indicative of significant pain). This scale was evaluated by blinded post-operative anesthesia care unit (PACU) Registered Nurses (RNs) at admission to PACU.


Enrollment: 50
Study Start Date: February 2012
Study Completion Date: November 2014
Primary Completion Date: November 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: TAP Group
Enrolled subjects will receive a TAP block with 0.5cc/kg of 0.25% ropivacaine.
Procedure: TAP block
TAP Block will be performed under ultrasound guidance via Sonosite device with an in-plane technique by the anesthesiologist.
Active Comparator: Local Infiltration Group
Enrolled subjects will receive will receive local infiltration of 0.5 cc/kg of 0.25% ropivacaine.
Procedure: Local Infiltration
Local infiltration of 0.5 cc/kg of 0.25% ropivacaine will be administered by the surgeon.

Detailed Description:
This single-center, prospective, single blind, randomized study will enroll up to 50 subjects who are scheduled for elective hydrocelectomy and/or hernia repair. At Beaumont Health System, post-operative pain management in children is managed either via oral/parenteral opiates and opiate adjuncts, surgeon-administered field blocks (instillation of local anesthetics in the general area of incision), or via regional techniques (spinal, epidural, or peripheral nerve blocks). We have designed this study to determine if there is improved qualitative and quantitative post-operative pain control in patients receiving TAP block versus intraoperative peri-incisional, surgeon administered field block. Once informed consent has been given, each patient will be randomized (like flip of the coin) to either Transverse Abdominis Plane Block (TAP Block)or surgeon administered anesthesia.
