Introduction of the Couder manoeuvre and perineal injuries

Objective. - To analyse the introduction of the Couder manoeuvre in our level 3 maternity unit shortly after its introduction in 2019. Then, to evaluate and compare the rate of perineal injuries between 2017, when the manoeuvre was not performed at all, and 2020.Materials and method. - A single-centre retrospective study of patients who delivered a singleton eutociously at term from 1 January to 31 December 2017 and 2020.Results. - In total, 2930 records were analysed. The Couder manoeuvre rate was 32.12% in 2020. A change in the distribution of perineal lesions was observed: the rate of intact perineum increased (P < 0.001), while 2nd degree lesions decreased between 2017 and 2020 (P < 0.05). The 1st degree perineum and obstetric anal sphincter injuries remained stable. The rate of episiotomy decreased significantly by almost a factor of 7.Conclusion. - The practice of the Couder manoeuvre can be implemented fairly quickly after training of the actors with nearly a third of normal deliveries at term concerned one year after its introduction. This manoeuvre seems, in our practice, to have contributed to the reduction, as previously reported, of the rate of second degree perineal injuries.(c) 2021 Elsevier Masson SAS. All rights reserved.
