[Peridural analgesia with 0.375 percent bupivacaine in labor with dystocia]. / Analgésie péridurale par la bupivacaïne à 0,375% au cours des accouchements dystociques.

For dystoctic deliveries peridural analgesia with bupivacaine 0.25% was compared with bupivacaine 0.375%, without adrenalin. Shortening of the delivery time in cases of stagnation of dilatation, was obtained with bupivacaine 0.375%: 181 mn in the average instead of 276 mn with bupivacaine 0.25% (p = 0.05). In the case of a cervical spasm, there was release of the contraction with return of a normal dilatation leading to a shorter labour: 188 mn in the average against 340 mn (p = 0.02) with the 0.25% solution. Apgar scores were similar in both series.

[Primary-purpose peridural analgesia in labor induction]. / Analgésie péridurale de première intention dans le déclenchement du travail.

21 parturients, showing in most of cases either high blood pressure badly controlled or a "real" out of date term, have undergone a peridural analgesia of first intention in labour induction. All these patients were considered to be uninducable according to Bishop score. After an injection of adrenalinized bupivacaïne, either 0.25% or 0.375% rupture depending on state of cervix of membranes occurred in most cases 6 hours after peridural analgesia. The mean between onset of analgesia and delivery was 17 h and the mean time between induction with ocytocin to birth 5 h 37 min. 16 parturients gave birth per vaginam, 9 of which spontaneously 5 have undergone caesarian section because of a non lack of dilatation or foetal distress. Children at birth, at the 2nd and the 24th hour were all healthy.
