Reducing Chronic Pain After Lung Surgery: A Trial of Limiting NSAIDs During Recovery

Brief summary (from the registry)

Chronic postoperative pain (CPOP) after video-assisted thoracic surgery (VATS) is severe because it results from lesions at multiple levels: incisions, pulmonary or nerve contusions. PCOD is defined by the IASP (International Association for the Study of Pain) as persistent pain 3 months after surgery. It affects around 30% of patients and significantly impairs recovery and quality of life. One of the many factors contributing to the appearance of PCOD is acute perioperative pain. To combat this acute pain and limit postoperative chronic pain, a multimodal analgesia strategy is necessary, particularly during thoracic surgery with a high nociceptive potential. This type of protocol will enable acute pain to be controlled by various means: tier 1 analgesics (paracetamol, NSAIDs), tier 2 (nefopam, tramadol) and tier 3 (opioid drugs), locoregional anaesthesia, co-analgesics and non-medicinal techniques. Thus, avoiding NSAIDs will have no effect on the increase in acute pain. A study of the impact of eliminating NSAIDs on chronic pain can therefore be carried out without increasing patients' acute pain. A team from McGill University, Montreal, Canada, recently discovered a paradoxical effect of anti-inflammatory drugs on the chronicisation of pain. They demonstrated that although anti-inflammatory drugs initially had an acute analgesic effect, they induced neutrophil depletion and a drastic change in the transcriptome postoperatively, leading to more chronic pain. These studies highlight the fact that although NSAIDs have an acute analgesic effect, their use could ultimately prove counterproductive by encouraging the development of CD. However, to date there are no studies demonstrating that a minimum dose or duration of NSAID treatment leads to the development of DCPO. On the basis of these results, it is justified to assess the impact of NSAIDs widely used in routine care in thoracic surgery on the development of DCPO. In order to improve pain management in the intraop…
