Although interesting and perhaps relevant to settings which require motor block resolution before discharge from PACU (or when there are bupivacaine shortages), the practical relevance of this study is questionable.
Notable in this French study is the extended duration of PACU stay after caesarean section: more than 2 hours in the prilocaine group, and 3 hours in the bupivcaine group! It is unclear whether this is routine post-CS care, or specific to the study design to allow for motor block assessment.
Also of note, the caesarean sections were "...performed using Misgav-Ladach technique with externalisation of the uterus" which may again make this study less relevant in settings where it is routinely accepted that avoiding uterine externalisation makes for better patient experience.

For women undergoing elective caesarean section, intrathecal hyperbaric prilocaine results in significantly shorter motor block than hyperbaric bupivacaine, with no difference in maternal hypotension, pain or satisfaction.
