The aim of this placebo-controlled clinical trial is to assess the effectiveness of the local
infiltration of the analgesic Chirocaïne® on perineal pain after episiotomy or first-degree
tear. The pain intensity is measured in immediate postpartum period by using a numerical
rating scale (NRS) at the following times: H2, H4, H8, H12, H24, H36, H48 during rest,
defecation and during activities. The safety of Chirocaïne® and the patient satisfaction are
also evaluated at each time.
