Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of morphine and ropivacaine following knee arthroscopy.
The purpose of this study was to compare the effectiveness of ropivacaine, a new local amidic anesthetic, compared with morphine as an intra-articular drug in controlling pain in patients after arthroscopic knee surgery. ⋯ Although its cost is very high compared with morphine, ropivacaine is a safe, site-specific, and long lasting anesthetic drug with an earlier onset than morphine and almost the same duration, covering the whole postoperative period (24 hours).
