[Obstetric analgesia using nitralgin inhalation and lumbal peridural anesthesia (a model for obstetric analgesia)].

Authors report the systems of anesthesia used at their ward for delivery in the last eight years. Nitralgin inhalation is used since 1981, lumbar peridural anesthesia is used since 1983. Of 13,458 deliveries in case of 3893 parturiants Nitralgin analgesia was used, while LEDA was used for 2300 parturients. By means of Nitralgin inhalation system it could be assured in the delivery room to apply the pain relief gas mixture (Nitralgin) simultaneously for several parturients. With direction of anesthesiologists employed for the ward the LEDA was attained by gynecologists knowing the use and application of general anesthesia. Thus the continuous application of both procedures can be ensured in 24 hours a day. In our study the frequency of vacuum extraction (0.26 p. c.) and that of Cesarean section (12.81 p. c.) did not increase. With application of these methods it could be achieved that 60 p. c. of vaginal deliveries are performed with anesthesia. Authors propose their system for wider application since in the same ward more and more parturients can be applied anesthesia for pain relief at vaginal delivery.
