This single-center, prospective, single blind, randomized study will enroll 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.

Further study details as provided by William Beaumont Hospitals:

Primary Outcome Measures:
  • FLACC: Face, Legs, Activity, Cry, and Consolability Pain Assessment Scale (FLACC)evaluated by blinded post-operative anesthesia care unit (PACU) Registered Nurses (RNs). [ Time Frame: Admission into PACU until hospital discharge, between 1 - 2 hours. ] [ Designated as safety issue: No ]
  • Phone call to parents for pain medication at 24 hours post hospital discharge. [ Time Frame: At 24 hours after hospital discharge. ] [ Designated as safety issue: No ]
  • Total pain medication from time of PACU admission until 24 hours post-operatively as documented by all pain given. [ Time Frame: From PACU admission until 24 hours after hospital discharge. ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Parental satisfaction with pain control, as measured by a 10 point Likert scale. [ Time Frame: Telephone call to parents at 24 hours post hospital discharge. ] [ Designated as safety issue: No ]

Estimated Enrollment: 50
Study Start Date: February 2012
Estimated Study Completion Date: January 2015
Estimated Primary Completion Date: August 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: TAP Group (TG)
