Brief Summary

Hyperbaric bupivacaine 0.5% associated with opioids is the local anesthetic the most commonly used for spinal injection in cesarean section. Nevertheless, its use often results in a long duration of motor nerve block and a haemodynamical instability. Recently developped, the Prilocaine, with its new 2% hyperbaric formulation, seems to offer a good alternative for hyperbaric bupivicaine. A first study has determined the ED95 of hyperbaric prilocaine 2% for intrathecal anesthesia in scheduled cesarean delivery. As opioid adjuvants potentiate the effect of the local anesthetics while decreasing their dose-related side effects, the aim of this study is to determine the ED95 of hyperbaric prilocaine 2% with sufentanyl for scheduled cesarean delivery under spinal anesthesia,by using the Continual Reassessment Method (CRM)

Outcome Measures

Primary Outcomes (1)

  • Success of Anesthesia

    The nerve blockade will be considered as success when a bilateral T4 level will reach in 15 minutes after intrathecal injection without additional epidural injection needed within 45 minutes peri-operative ; no pain at the skin incision, no pain during 45 minutes after the skin incision

    during surgery (average 1 hour)

Secondary Outcomes (13)

  • Sensitive Block Duration

    Until complete release of sensory block (T12-S1) (average 4 hours)

  • Sensitive Block at End of Surgery

    Until complete release of sensory block (T12-S1) (average 4 hours)

  • Motor Block Duration

    Until complete release of motor block (Bromage scale = 1; average 4 hours)

  • Bromage Motor Block Level at End of Surgery

    Until complete release of motor block (average 4 hours)

  • Newborn Apgar Score

    up to 10 minutes after baby extraction

  • +8 more secondary outcomes

Cohort 1 : HB prilocaine 2%, 45mg

EXPERIMENTAL

Dose-finding study with 4 subjects per dose and a maximum of 40 parturients.To identify the dose to give for reaching the ED95 (effective dose for 95% subjects), Hyperbaric prilocaine 2%, associated with sufentanyl, will be administrated at the dose initial of 45 mg in the cohort 1 (4 subjects), then the dose will be adjusted in the next cohorts using the Continual Reassessment Method (CRM).
