Injectable aspirin as a postoperative analgesic.

E McAteer, J W Dundee

    British Journal of Anaesthesia
    |October 1, 1981
    PubMed
    Summary

    Lysine acetyl salicylate (LAS) at 1.8g did not effectively relieve severe postoperative pain compared to morphine. While LAS showed some pain relief, morphine provided more consistent and effective analgesia.

    Area of Science:

    • Pharmacology
    • Pain Management
    • Anesthesiology

    Background:

    • Postoperative pain is a significant clinical challenge.
    • Effective analgesia is crucial for patient recovery and comfort.
    • Non-opioid analgesics are sought to manage pain while minimizing side effects.

    Purpose of the Study:

    • To compare the efficacy of lysine acetyl salicylate (LAS) with morphine for severe, immediate postoperative pain.
    • To evaluate the effectiveness and consistency of LAS analgesia.
    • To determine the analgesic potential of LAS in a clinical setting.

    Main Methods:

    • A comparative study involving patients with severe postoperative pain.
    • Administration of a single injection of lysine acetyl salicylate (1.8 g, equivalent to aspirin 1 g).
    • Comparison of LAS efficacy against a single injection of morphine (10 mg).

    Main Results:

    • Lysine acetyl salicylate (1.8 g) did not provide effective or consistent pain relief.
    • Morphine (10 mg) demonstrated effective and consistent analgesic action.
    • Lysine acetyl salicylate exhibited some degree of analgesic activity, though less potent than morphine.

    Conclusions:

    • Morphine is a more effective and reliable option for severe, immediate postoperative pain management compared to LAS.
    • Lysine acetyl salicylate may possess limited analgesic properties but is insufficient for severe pain.
    • Further research may explore lower doses or different formulations of LAS for milder pain.
