[Comparison of continuous extradural analgesia during labor using 0.25% bupivacaine or mixtures of 0.25% bupivacaine and fentanyl]. / Porównanie ciaglej zewnatrzoponowej analgezji Porodu z uzyciem 0.25% Bupivacainy I mieszaniny 0.25% Bupivacainy z Fentanylem.

We have compared effects of epidural analgesia in labour in two groups containing 35 primiparous each and in two groups containing 35 multiparous each. We have administered either bupivacaine or bupivacaine with fentanyl. We have compared duration of the 1-st and the 2-nd stage labour, efficiency of analgesia, quantity of administered bupivacaine, method of delivery and condition of the newborn. This investigation has shown that use of 0.25% bupivacaine with fentanyl requires less quantity of bupivacaine in both groups of primiparous and multiparous. The addition of fentanyl to 0.25% bupivacaine can be beneficial alternative of epidural analgesia in labour.

[Comparative studies of nalbuphine and morphine in the therapy of postoperative pain in gynecology]. / Badania porównawcze nalbufiny i morfiny w leczeniu bólu pooperacyjnego w ginekologii.

A group of 40 women having undergone abdominal gynecological operations were studied for the comparative evaluation of nalbuphine and morphine. The analgetics were used to relieve postoperative pain in the technique of double blind trial. 20 women were administered 20 mg of nalbuphine and 20 women were administered 10 mg of morphine. Within 6 hours following the administered of each of the drugs, the authors evaluated the analgetic effectiveness, haemodynamic, ventilatory and gasometric parameters. Most of the women showed satisfactory and comparable analgetic effectiveness of the two drugs for six hours. No influence was found of any of the analgetics on the physiological parameters examined. The frequency and intensification of side-effects were the same both after administering nalbuphine and morphine. In the authors' opinion, in a proper dose, nalbuphine is an analgetic equal to morphine with respect to analgetic effectiveness and time of pharmacological action.
