Background and aims The use of loco-regional anesthesia aims at providing an adequate intra- and/or post-operative pain management for a broad spectrum of surgical interventions which historically have relied on the use of opioid drugs. on this fashion, the aim of our study is to prove that the use of bilateral continuous subcostal TAP block, in a multimodal opioid-sparing analgesic approach, provides successful post-operative pain management for major abdominal surgical interventions. We adopted the NRS score as a reference and ≤ 6 as an acceptable response.

Methods We enrolled (16) patients undergoing major abdominal surgery. a primer infusion of 1gr paracetamol + 30 mg ketoralac was administered 30 minutes prior to the end of the intervention. Moreover, in the immediate post-operative period, via US guidance, a 20 ml bolus of 0.5% levobupivacaine was administered bilaterally. Then a permanent catheter was placed on both sides with a 2ml/h infusion of 0.5% levobupivacaine (20 ml in 28 ml of 0.9% NaCl).

Results In the 30-minutes post-operative period, the NRS score was ≤ 4 for all of our patients. Then ≤ 3 in the 6, 12 and 24-hour post-operative period. None of our patients requested any supplementary analgesics.

Conclusions The major drawback of this study is the small size of our sample. Further studies might encourage the spread of this procedure as a new gold-standard for laparoscopic interventions (e.g. right hemicolectomy and laparocele) and its non-inferiority to epidural analgesia, the current gold-standard for laparotomic surgeries (especially left hemicolectomy).
