Brief Summary:
This study was conducted to demonstrate post-abdominoplasty analgesic duration consequent to three different surgically infiltrated LA techniques; bilateral TAPB, bilateral RSB and subcutaneous infiltration using the same volume of 0.25% bupivacaine (40 ml). Pain score, total analgesic rescue requests and the total amount of systemic rescue analgesia used in the first postoperative day in addition to any detected postoperative complications were also recorded.

Condition or disease Intervention/treatment Phase

Official Title: The Efficacy of Three Different Surgically Infiltrated Local Anesthetic Techniques in Abdominoplasty
Actual Study Start Date : March 1, 2017

Estimated Study Completion Date : June 15, 2017

Arm Intervention/treatment
Active Comparator: Transevrsus abdominus plane block group Drug: Transevrsus abdominus plane block
a blunt needle was advanced in the midaxillary line to reach the fascial layer between the internal oblique and transverse abdominis muscles detected by facial click sensation. The LA was slowly injected so as to detect any sign of toxicity or incorrect needle tip position (as resistance) requiring needle repositioning then TAPB was repeated on the opposite side.

Active Comparator: Rectus sheath block group Drug: Rectus sheath block
In RSB group, 2-3 cm from midline, about 3-5 cm above the umbilicus, the needle was advanced at right angle to the skin. The needle reaches the space between the posterior layer of the rectus sheath and rectus abdominis muscle detected by firm resistance of the posterior wall, The LA was slowly injected then the same steps were repeated on the other side.

Active Comparator: local infiltration group Drug: local anesthesia infiltartion
40 mls of 0.255 bupivacaine will be infiltrated at skin incision

Primary Outcome Measures :
  1. morphine consumption (mg) [ Time Frame: up to 24 hours ]
    postoperative morphine consumption in milligrams in the 1st 24 hours postoperatively
