Background: Abdominoplasty is a common aesthetic procedure. The transversus abdominis plane block (TAPB) and rectus sheath block (RSB) have proven efficacy as analgesic modality for abdominal surgeries. This study demonstrates post-abdominoplasty analgesic duration consequent to the three surgically infiltrated local anesthetic techniques: bilateral TAPB, bilateral RSB, and subcutaneous infiltration (SCI) of 0.25% bupivacaine. Methods: In this prospective randomized study, 48 adult patients scheduled for abdominoplasty were randomized into three groups: TAPB group (n = 16), RSB group (n = 16), and SCI group (n = 16) utilizing 40 mL of 0.25% bupivacaine for each block. In both TAPB and RSB groups, the block was performed bilaterally after plication of anterior abdominal wall, while in SCI group, the surgical incisional area was infiltrated before skin closure. Main outcome measures included visual analogue scale (VAS), at rest and during movement; the analgesic duration; and the total required doses of morphine in the first postoperative day. Results: A statistically significant longer analgesia was recorded in the TABP group compared with both the RSB and SCI groups. Statistically significant higher VAS scores in the SCI group 4 hours postoperatively was recorded, both at rest and during movement, compared with both TABP and RSB groups. Significant higher morphine consumption in the SCI group was compared with the other two groups. Conclusions: Among the surgically infiltrated anesthetic techniques for abdominoplasty, bilateral TAPB was associated with longer postoperatively analgesic duration with lower morphine consumption in the first 24 hours compared with RSB and SCI.
