Effects of esketamine combined with parecoxib sodium on early postoperative pain and inflammatory biomarkers after video-assisted thoracoscopic lung resection: a single-center, four-arm randomized controlled trial
This single-center, four-arm randomized controlled trial demonstrates that combining esketamine with parecoxib sodium provides superior early postoperative pain relief and reduces inflammatory biomarker levels compared to either agent alone or saline control in patients undergoing video-assisted thoracoscopic lung resection.

Imagine your body as a bustling city. When a construction crew (surgeons) has to fix a major problem inside a building (your lungs), they have to open up the site, move things around, and deal with a lot of noise and dust. In the medical world, this is called surgery. Even with modern, tiny cameras and small cuts (known as video-assisted thoracoscopic surgery, or VATS), the body still reacts like a city under siege. It sends out "alarm sirens" called pain signals and releases "smoke signals" called inflammation markers. These smoke signals, specifically chemicals like Interleukin-6 (IL-6) and C-reactive protein (CRP), tell the rest of the body that something is wrong, which can make recovery slower and more uncomfortable. Doctors have long tried to find the perfect "fire extinguisher" to put out these alarms and smoke without causing new problems, like making the patient too sleepy or dizzy. They often use a mix of different tools, a strategy called "multimodal analgesia," hoping that combining a few different types of fire extinguishers works better than just one.
This study is like a science fair experiment where researchers tested two specific fire extinguishers to see if using them together was the ultimate solution for lung surgery patients. The two tools were esketamine, a drug that acts like a "noise-canceling headphone" for the brain's pain receptors, and parecoxib sodium, a drug that acts like a "cooling spray" to reduce swelling and inflammation at the injury site. The researchers wanted to know: if they used both at the same time, would patients feel less pain and have less "smoke" (inflammation) in their bodies compared to using just one or neither? They set up a race with four teams of patients: one team got only the cooling spray, one got only the noise-canceling headphones, one got both, and one got a fake treatment (a saline placebo) to act as the control group.
The race took place at a hospital in Chongqing, China, involving 100 patients who were having lung surgery. The researchers checked the "pain scores" (how much it hurt on a scale of 0 to 10) and the "smoke levels" (the amount of IL-6 and CRP in the blood) at various times after the surgery. The results were quite interesting. When they looked at the pain scores, the team that got both drugs (the PS group) had the lowest average pain scores at 6 hours, 12 hours, 24 hours, and 48 hours after the surgery. However, the difference wasn't huge right after the patient woke up (30 minutes after the breathing tube was removed), likely because everyone got a standard dose of strong painkillers at that moment. But as time went on, the combination team seemed to stay ahead.
The "smoke" results were even clearer. The team with both drugs had the lowest levels of IL-6 and CRP on the first, third, and sixth days after surgery. This suggests that the combination might help calm down the body's overall stress response better than using just one drug or a placebo. On the flip side, the team that got only the esketamine (the noise-canceling headphones) did have slightly higher heart rates and blood pressure right when the surgery started, which makes sense because esketamine can sometimes give the body a little energy boost. But overall, the study found that the combination was safe, with very few side effects like nausea or dizziness across all groups.
So, what does this all mean? The study suggests that giving patients both esketamine and parecoxib sodium might be a winning strategy for keeping pain low and inflammation down during the first few days after lung surgery. The authors are careful to say these are "exploratory findings," meaning it's a strong hint that needs more testing in bigger studies to be sure. They didn't prove it's a miracle cure, but they did show that the "two-tool" approach looked better than the single tools or the fake treatment in this specific race. It's a promising step toward helping patients recover from lung surgery with less discomfort and a calmer body.
