[Evaluation of subarachnoid anesthesia using local anesthetics in combination with morphine].

The efficacy of subarachnoidal anesthesia with lidocaine (trimecaine) in combination with small morphine doses was compared to anesthesia with lidocaine (trimecaine) alone. The analysis of the results obtained has demonstrated that the combination of local anesthetics (lidocaine, trimecaine) with minimum doses of narcotic analgesics (morphine) improves considerably the quality of anesthesia, enhancing the blockade of nociceptive impulsation from the operative area and ensures prolonged postoperative analgesia.
