[Comparison between extradural morphine and lysine acetylsalicylate in the treatment of postoperative pain]. / Confronto tra morfina extradurale e acetilsalicilato di lisina (ASL) nel trattamento del dolore post-operatorio.

We have compared the analgesic properties in post-operative pain using Morphine (3 mg) injected in the extradural space and I.V. Lysine acetil salicilate (ASL) (1.8 g). Extradural morphine is much more effective in eliminating pain and in prolonging the analgesia. Insignificant the side effect for both treatments. The authors underline the possibility of dependence with extradural morphine especially in those cases when morphine is repeated more than 2-3 times.
