AbstractTransversus abdominis plane (TAP) blocks can provide analgesia postoperatively for a range of surgeries. Abundant clinical trials have assessed TAP block showing positive analgesic effects. This systematic review assesses safety and effectiveness outcomes of TAP block in all clinical settings, comparing with both active (standard care) and inactive (placebo) comparators. PubMed, EMBASE, The Cochrane Library and the University of York CRD databases were searched. RCTs were screened for their eligibility and assessed for risk of bias. Meta-analyses were performed on available data. TAP block showed an equivalent safety profile to all comparators in the incidence of nausea (OR = 1.07) and vomiting (OR = 0.81). TAP block was more effective in reducing morphine consumption [MD = 13.05, 95% CI (8.33, 51.23)] and in delaying time to first analgesic request [MD = 123.49, 95% CI (48.59, 198.39)]. Postoperative pain within 24 h was reduced or at least equivalent in TAP block compared to its comparators. Therefore, TAP block is a safe and effective procedure compared to standard care, placebo and other analgesic techniques. Further research is warranted to investigate whether the TAP block technique can be improved by optimizing dose and technique-related factors.
