Persistent Pain Induced by Uniportal Video-assisted Thoracic Surgery

Status Recruiting

Clinical Trial Summary

The investigators investigate the prevalence of PTPS in patients receiving with uniportal video-assisted thoracic surgery (VATS), and early identify neuropathic pain as well as treated with neural protective strategy to target intercostal nerve.

Clinical Trial Description

More than 30% of patients have persistent pain after thoracic surgery. Intercostal neuralgia is characterized by neuropathic pain in the distribution of affected intercostal nerve(s) (along the ribs, chest, or abdomen) that commonly manifests as a sharp, aching, radiating, burning, or stabbing pain and may be associated with paresthesia such as numbness and tingling. The pain may be intermittent or constant and typically presents as a band-like pain that is wrapped around the chest and back or in a thoracic dermatomal pattern. Pain may last for a prolonged period and may continue long after the disease process has subsided. Hypertonic dextrose injection (prolotherapy) is reported to reduce pain, including non-surgical chronic low back pain (CLBP), and subcutaneous injection of 5% dextrose is said to minimize neurogenic pain hyperalgesia and allodynia. The mechanism in both cases is unclear, though a direct effect of dextrose on neurogenic pain has been proposed. This study assessed the short-term analgesic effects of epidural 5% dextrose injection compared with saline for non-surgical CLBP. Intercostal nerve damage is a suspected pathogenic mechanism for developing post-thoracotomy pain syndrome (PTPS). Video-assisted thoracic surgery (VATS) is a minimally invasive procedure that potentially reduces PTPS. However, there was no specific outcome study for uniportal VATS. In this study, the investigators investigate the prevalence of PTPS in patients receiving uniportal video-assisted thoracic surgery (VATS), identify neuropathic pain early, and treat it with a neural protective strategy to target intercostal pain nerve. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
