Study of Transverse Abdominis Plane (TAP) Block in Children Undergoing Hydrocelectomy and/or Hernia Repair Surgery

Kaveh Aslani, MD50 enrolled

Overview

Study measures the difference in pain after hernia \&/or hydrocele repair based on site of local anesthesia injection.

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.

Outcomes

Primary Outcomes

FLACC: Face, Legs, Activity, Cry, and Consolability Pain Assessment Scale (FLACC)

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.

Time frame: Admission into PACU
