Impact of walking epidural analgesia on obstetric outcome of nulliparous women in spontaneous labour.

BACKGROUND: To explore the effects of walking epidural analgesia on obstetric and neonatal outcomes, we performed a case-control study. METHOD: Each nulliparous woman receiving walking epidural analgesia using 0.0625% bupivacaine (n = 44) was matched to two nulliparous historical controls receiving 0.125% or 0.25% bupivacaine (n = 88 each) for epidural analgesia while recumbent. RESULTS: Maternal and obstetric parameters, fetal status and presentation, and oxytocin use were comparable among groups. Those receiving walking epidural analgesia walked for a mean of 60 min (range: 20-75 min). In the control groups the mean total durations of labour were shorter (58 min in the 0.125% group and 99 min in the 0.25% group, P < 0.05). Significantly fewer walking epidural analgesia cases than controls required instrumental vaginal delivery (P < 0.05). No other differences in obstetric or fetal outcome were observed and no mother fell or stumbled while walking. CONCLUSION: Although it was associated with a prolonged first stage of labour, walking epidural analgesia appeared safe for nulliparous women and their babies.

[Repeated thromboembolism during pregnancy with constitutional antithrombin deficiency]. / Thromboses récidivantes gravidiques et déficit en antithrombine.

We report the case of a twenty-three-year old woman with constitutional antithrombin deficiency, who had oral anticoagulation since she was four years old. During her first pregnancy, after the introduction of unfractionated heparin prophylactic therapy, she presented a first venous thromboembolism at nine weeks, and a second one with low-molecular-weight heparin therapy at nineteen weeks. Because of a severe antithombin deficiency, regular infusions of antithrombin concentrates were necessary until delivery to ensure effective anticoagulation by heparin. Patients with antithrombin deficiency have a very high risk of venous thromboses during the pregnancy and post-partum. We discuss the significant points of management for this period.

[Antagonistic effects of naloxone against morphinomimetic agents. Apropos of 10 cases in gynecologic surgery]. / Etude des effets antagonistes de la naloxone à l'égard des analgésiques morphinomimétiques. A propos de 10 cas en chirurgie gynécologique.

The object of this study was the use of naloxone to correct hypoventilation related to the use of morphinomimetics without suppressing the analgesic effect of these agents. The study involved ten patients undergoing gynaecological surgery under neuroleptanalgesia and who at the end of surgery had hypoventilation due to the use of fentanyl (average dose : 4.87 microgram/kg/h) or phenoperidine (average dose : 48.7 microgram/kg/h). Naloxone was administered intravenously in an average dose of 1.37 microgram/kg (in one or two injections) followed by an intramuscular injection of an average of 0.73 microgram/kg. Under these conditions, respiratory depression was completely corrected in all cases, the effect being durable. Good analgesia was retained and there was a normal return to consciousness without undesirable effects.
