Pre-Emptive Parecoxib Sodium for Pain Control During CT-Guided Lung Nodule Localization

Sponsor: Long Jiang

Summary

Before undergoing minimally invasive lung surgery, patients with small lung nodules often need a procedure called "CT-guided hook wire localization." This involves using a CT scanner to help doctors place a tiny wire in the lung to mark the exact location of the nodule for the surgeon. While very helpful for the surgery, this wire placement can be highly painful for patients. The main purpose of this clinical trial is to find out if giving patients a pain-relieving medication called parecoxib sodium before the procedure can effectively reduce their pain. Parecoxib sodium is a standard, non-opioid painkiller given through an IV. Additionally, researchers want to discover the best time to give this medication. Because operating room schedules can change, patients will receive the IV medication at different times before their localization procedure (ranging from less than an hour to more than 3 hours beforehand). By looking at these different wait times, researchers hope to identify the "golden window"-the exact timing that provides the most pain relief. During the study, participants will be randomly assigned by a computer to one of two groups: The Study Group: Will receive the active pain medication (parecoxib sodium). The Control Group: Will receive a placebo (a saltwater solution with no active medicine). To ensure the results are fair and unbiased, participants have a 2 in 3 chance of receiving the active medication, and neither the patients nor their doctors will know which assignment they received. Immediately after the wire is placed, participants will be asked to rate their pain on a scale of 0 to 10. By comparing the pain scores between the two groups and looking at the different medication timings, researchers hope to create better, more comfortable care guidelines for future lung surgery patients.
