NCT01559740

Brief Summary

After undergoing hernia surgery, hydrocelectomy or lower abdominal surgery, a child may experience some amount of pain in the post-operative period. As part of the anesthesia technique, the investigators routinely provide a nerve block done on the abdominal wall that will provide pain relief for at least 10 hours postoperatively. This is referred to as a TAP block. The purpose of this study is to determine if the nerve block performed with local anesthetic solution using a regular concentration solution vs. a diluted solution may offer different durations of pain relief.

Outcome Measures

Primary Outcomes (1)

  • TAP Block Concentration of Bupivacaine that Reduces Postoperative Pain

    The difference in concentrations will be measured by using FLACC score every 5 mins for one hour after surgery in the Post Anesthesia Care Unit. Blood pressuer and heart rate will also be recorded.

    Participants will be followed for the duration of anesthesia and after surgery, an average of 48 hours

Secondary Outcomes (3)

  • Dose of rescue medications given between the two groups

    Participants will be followed for the duration of anesthesia and after surgery, an average of 48 hours

  • Number of rescue medications given between the two groups

    Participants will be followed for the duration of anesthesia and after surgery, an average of 48 hours

  • Time the rescue medications were administered between the two groups

    Participants will be followed for the duration of anesthesia and after surgery, an average of 48 hours

Study Arms (2)

0.25% Bupivacaine

EXPERIMENTAL

All children will receive a single dose of 1 mcg/kg of Fentanyl intravenously prior to incision. Group TAP 1 receiving a TAP block with 0.25% bupivacaine with 1:200,000 epinephrine at a dose of 1 mL/kg.

Drug: Bupivacaine

0.125% Bupivacaine

EXPERIMENTAL

All children will receive a single dose of 1 mcg/kg of Fentanyl intravenously prior to incision. Group TAP 2 will receive a TAP block with a total dose of 1 mL/kg given at a concentration of 0.125% bupivacaine with 1:200,000 epinephrine.

Drug: Bupivacaine

Interventions

This is being used as the local anesthetic for the TAP blocks at either 0.25% or 0.125%. The block will be done once during the procedure.
