[Prevention and treatment of postoperative pain syndrome in extensive thoracoabdominal oncological surgery].

A procedure has been developed and tested to prevent and treat postoperative pain syndrome during extensive thoracoabdominal surgery for esophageal cancer. The procedure is based on the preventive (12 hours before anesthesia and surgery) application of Durogesic (fentanyl transdermal therapeutic system (TTS)) at an opioid release rate of 50 microg/h for 72 hours. By the end of surgery and anesthesia when intravenous injection of fentanyl is stopped, analgesia continues to be maintdined due to its therapeutic dose coming from TTS. This prevents the development of acute opioid tolerance, hyperalgesia, and destabilization state in the early postanesthetic period and creates the basis for continuous multimodal postoperative analgesia in combination with nonopioid components (lornoxicam, perfalgan) and with none or minimal need for the injectable opioid. This allows an operated patient to have a comfort and stable state. A further investigation on the comparative assessment of the developed procedure with other variants of perioperative systemic and combined anesthesia-analgesia is to be conducted.
