691 The Efficacy of the Transversus Abdominis Plane Block in Abdominoplasty: A Systematic Review and Meta-Analysis

Résumé fourni par la source

Abstract Aim The transversus abdominis plane (TAP) block is a regional abdominal anaesthetic technique frequently used within non-cosmetic abdominal surgery. The literature is devoid of a meta-analysis to quantitatively amalgamate the results of individual reports analysing the efficacy of TAP block compared to alternative analgesic methods in abdominoplasty surgery. The authors aimed to conduct the first meta-analysis within the literature to evaluate this technique’s effectiveness in abdominoplasties. Method PRISMA guidelines were referred to conduct this systematic review and meta-analysis. All observational and randomised controlled trials (RCTs) comparing the postoperative outcomes of patients who underwent abdominoplasties with TAP blocks versus no TAP blocks were included in this study. The time taken to first analgesia and the amount of analgesia used were the primary outcome measures. The secondary outcome measures include severity of pain, time to mobilisation, and length of stay. Random effect modelling was used for the analysis. Results The time taken to the first analgesic was significantly lower in the TAP cohort (p <0.05). In addition, there was a lower incidence of postoperative nausea/vomiting (OR 0.18, 95%CI 0.04 - 0.90, p=0.04). Mean total opioid use and operative time were comparable between the TAP and no TAP groups. A qualitative review of the visual analogue scale for pain amongst the included studies showed that it was lower in the TAP group. Conclusions The authors report the first meta-analysis within the literature showing the efficacy of the TAP block in abdominoplasties. Further high-quality trials are recommended to further the current evidence base.
