Summary

This study compares two painkiller combinations—dezocine plus sufentanil versus nalbuphine plus sufentanil—for pain relief after oral cancer surgery with flap reconstruction. Sixty adults will receive one of the two combinations through a patient-controlled pump. The goal is to see which provides better pain control, fewer side effects, and better flap survival.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
dezocine and nalbuphine (opioid painkillers)
What this could lead to
If it works, this could identify a safer, more effective pain management option for oral cancer patients after surgery.
What could go wrong
This is a small, early-stage trial with only 60 participants, so results may not apply to everyone. The drugs are already approved, so no major breakthrough is expected.
