The objective of this article was to review the evidence regarding multimodal analgesia drugs and regional block techniques in the context of thoracic surgery, with a special focus on video-assisted thoracic surgery (VATS). Background: Despite advances in surgical technique and the increased use of minimally invasive surgery, postoperative pain after thoracic surgery is still significant, especially in the first two postoperative days. Inadequate pain control leads to a reduced rate of

However, the optimal analgesic protocol that allows adequate postoperative pain control and facilitates fast recovery of this population has yet to be determined. Methods: An extensive review of articles published between January 1980 and November 2020 using different combinations of search terms that were relevant to the topic was conducted using PubMed search engine. All published full articles randomised controlled trials comparing the analgesic efficacy of a regional block or of a multimodal analgesic drug to a placebo in patients undergoing either thoracotomy or VATS were included in this review. Conclusions: Analgesic protocols in thoracic surgery must take into consideration the surgery that is being performed (VATS or thoracotomy) as well as patient's characteristics. Regional blocks are highly effective at providing good postoperative pain control although their duration is limited. Various non opioid analgesic drugs have been evaluated in order to address the various pain generators that cause postoperative pain after thoracic surgery, although none has become a clinical standard. Using a combined multimodal and regional analgesic protocol could improve postoperative pain control and decrease the use of parenteral opioids and their unwanted side effects. Recommendations on multimodal analgesic protocols are given based on the literature.
