Objective. we aimed to compare the anesthetic and analgesic effect of the pudendal nerve block (PNB) and of the local lidocaine infiltration during episiotomy repair and in the following 24 hours.Patients and Methods. 70 parturients undergoing natural birth requiring episiotomy and presenting contraindication or refusal of epidural analgesia were randomized to receive pudendal nerve block with ropivacaine or local lidocaine infiltration. The main endpoint was: evaluation of obstetric analgesia by visual analogical scale . The secondary judgment criteria were: hemodynamic parameters, suture duration, onset time of sensory block, time to first analgesic request, rehabilitation parameters, parturient and obstetrician satisfaction and pain intensifying factors.Results. Mean VAS pain score was significantly lower in pudendal group versus infiltration group at T10min(10 minutes after local anesthetic injection) (

Objective. Aim of this study is to compare the effect of the initial bolus: 10 ml of ropivacaine 0.2% (small volume, high concentration) and 20 ml of ropivacaine 0.1% (high volume, low concentration) during obstetric labor on the motor block, hemodynamic consequences, analgesia and parturient satisfaction.Patients and Methods. 56 parturients were included in this prospective, randomized, double-blind study. The parturients were randomized into two groups: group 1 receiving an initial bolus of 10ml of ropivacaine at 0.2% + 5 gamma of sufentanil and group 2 receiving an initial bolus of 20ml of ropivacaine at 0.2% + 5 gamma of sufentanil. The main endpoint was the evaluation of motor block.The secondary judgment criteria were: haemodynamic consequences, evaluation of obstetric analgesia by visual analogical scale, evaluation of the sensory level and satisfaction of the parturient.Results. The haemodynamic consequences were comparable for the 2 groups (p>0.05). The means of the VAS were similar (p>0.05). Motor block was similar in the 2 groups (14.81% for group 1 versus 6.89% for group 2 with p=0.57). A statistically significant difference was noted according to the sensory level which was higher in group 2 (p<0.05). The mean satisfaction was without significant difference (p=0.64). The adverse effects were similar in the two groups (p>0.05).Conclusions. Our study does not show a benefit of the use of a high volume low concentration compared to the use of small volume high concentration during the induction of the epidural.
