The hemiclamshell incision is a valid but infrequent surgical alternative for the resection of tumors from mediastinum. This point makes this approach impossible to be studied under a randomized controlled trial. The triple association of thoracotomy, sternotomy and cervicothomy makes the hemiclamshell approach a high intensity postoperative pain surgery. However, there is no published data on this topic, and the reviewed articles only mention the analgesic regimens as a secondary point. Indeed, no author defines the best epidural drugs mixture for the patients. Multimodal analgesic regimen based on regional anesthesia should be used. Based on the recent advances on spinal opioids, morphine could be a good choice as epidural coadjutant to local anesthetics for hemiclamshell incision.
