Brief summary
The planned cesarean section is an intervention with a standard operating time of less than 40 minutes in trained teams. Hyperbaric Bupivacaine is the local anesthetic (LA) reference for these operations. But the duration of its motor block is generally greater than 3 hours. The purpose of this study is to show a reduction in motor block time with hyperbaric Prilocaine by at least 30 minutes, which would allow mothers and their children to return to the maternity ward earlier and thus improve the circulation of patients within the maternity's PACU.
Detailed description
Prospective study, randomized into two parallel groups (Hyperbaric Prilocaïne versus hyperbaric Bupivacaine), double-blind, monocentric (Clinique Saint Roch in Montpellier). The number of subjects required is 50 patients, 25 per group.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| duration of motor block | up to 6 hours | To compare the duration of motor block after spinal anesthesia with hyperbaric Prilocaïne versus hyperbaric Bupivacaine This evaluation is done every 15 min from the entrance to the recovery room (PACU); the motor block stops being evaluated when the modified bromination score reaches 4 |

| APGAR score of newborns at birth | 1 day | APGAR score of newborns at birth. L'APGAR Apgar score is a method to quickly summarize the health of newborn children. The Apgar scale is determined by evaluating the newborn baby on five simple criteria on a scale from zero to two, then summing up the five values thus obtained. The resulting Apgar score ranges from zero to 10. The five criteria are summarized using words chosen to form a backronym (Appearance, Pulse, Grimace, Activity, Respiration). The test is generally done at one and five minutes after birth, and may be repeated later if the score is and remains low. Scores 7 and above are generally normal, 4 to 6 fairly low, and 3 and below are generally regarded as critically low. |

| Statifaction of the Surgeon | 1 day | The surgeon assessed his satisfaction while the cesarien section. The surgeon satisfaction score at 24 hours will be assessed by VAS (Visual Analogue Scale); Surgeon rate satisfaction on VAS from 0-10, 0 being no satisfaction and 10 being total satisfaction. |
