Abstract
Nerve block is widely used for pain management after video-assisted thoracoscopic surgery (VATS). Thoracic paravertebral block (TPVB), erector spinae plane block (ESPB), serratus anterior plane block (SAPB), and intercostal nerve block (ICNB) are alternative treatments. Network meta-analysis based on Bayesian analyses was performed to obtain results for direct comparison, indirect comparison, and network comparison, and to make rankings based on probabilities. Covariates were adjusted to determine the effect of the covariates on results of this study. The study identified 61 randomized controlled trials (RCTs) (4468 patients). There were results of probability ranking for the first ("best" treatment): 24 h morphine consumption, TPVB > ESPB > ICNB > SAPB. Covariate adjustment allowed the four treatments to change somewhat in the likelihood of the best choice. TPVB ranks best in our analysis. ESPB is a viable alternative. SAPB and ICNB seem to play a limited role in postoperative pain management.
