Background:
Several peripheral regional anaesthesia (RA) techniques are commonly used in thoracic surgery even in the absence of precise indications regarding their effectiveness on postoperative pain management.
Objective:
This systematic review and meta-analysis aims to describe and evaluate the relative effectiveness of different peripheral regional blocks and systemic analgesia in the context of video-assisted thoracoscopic surgery (VATS) or thoracotomy.
Design:
Systematic review of randomized controlled clinical trials (RCTs) with meta-analyses.
Data Sources:
We searched PubMed and Embase for all RCTs comparing the 24 hour morphine equivalents (MMEs) consumption following peripheral regional blocks and systemic analgesia (SA).
Eligibility Criteria:
We selected only RCTs including adult participants undergoing thoracic surgery, including esophagectomy and reporting on postoperative pain outcomes including 24 hour MMEs consumption.
Results:
Among the 28 randomized studies including adult participants undergoing thoracic surgery and reporting on 24 hour opioid consumption, 11 reporting a comparison of individual blocks with systemic analgesia were meta-analyzed. RA was effective for almost all peripheral blocks. Regarding intercostal block, its antalgic effect was not well evaluated SMD -1.57 (CI -3.88, 0.73). RA in VATS was more effective in reducing MMEs than thoracotomy SMD -1.10 (CI -1.78, -0.41).
Conclusions:
RA is a useful choice in thoracic surgery. However, it is still not possible to determine the most appropriate block in the individual surgical settings to be performed due to RCTs paucity.
