Resumo

JUSTIFICATIVA E OBJETIVOS: O parto vaginal pode resultar em dor perineal aguda e persistente pósparto. Este estudo avaliou a associação da catastrofização, fenômeno de má adaptação psicológica à dor que leva o indivíduo a magnificar a experiência dolorosa, tornando-a mais intensa, com a incidência e a intensidade da dor perineal e sua relação com o trauma perineal. MÉTODO: Estudo coorte. Realizado com gestantes em trabalho de parto. Foi aplicada a escala de pensamentos catastróficos sobre a dor durante o internamento e foram avaliados o grau da lesão perineal e a intensidade da dor perineal nas primeiras 24 horas e após oito semanas do parto por meio da escala numérica de dor. RESULTADOS: Avaliadas 55 mulheres. Sentiram dor aguda 69,1% das pacientes. Dessas, 36,3% queixaram-se de dor de moderada/forte intensidade e 14,5% de dor persistente. O escore médio de catastrofização foi de 2,15 ± 1,24. As pacientes catastrofizadoras apresentaram um risco 2,90 vezes maior (95% IC: 1,08-7,75) de apresentar dor perineal aguda e 1,31 vezes maior (95% IC: 1,05-1,64) de desenvolver dor perineal persistente. Também apresentaram um risco 2,2 vezes maior de desenvolver dor perineal aguda de maior intensidade (95% IC: 1,11-4,33). CONCLUSÕES: A incidência de dor perineal aguda e persistente após parto vaginal é alta. Gestantes catastrofizadoras apresentam maior risco de desenvolver dor perineal aguda e persistente, como também dor de maior intensidade. O trauma perineal aumentou o risco de ocorrência de dor perineal persistente.

Abstract

BACKGROUND AND OBJECTIVES: Vaginal birth delivery may result in acute and persistent perineal pain postpartum. This study evaluated the association between catastrophizing, a phenomenon of poor psychological adjustment to pain leading the individual to magnify the painful experience making it more intense, and the incidence and severity of perineal pain and its relationship to perineal trauma. METHOD: Cohort study conducted with pregnant women in labor. We used the pain catastrophizing scale during hospitalization and assessed the degree of perineal lesion and pain severity in the first 24 hours and after 8 weeks of delivery using a numerical pain scale. RESULTS: We evaluated 55 women, with acute pain reported by 69.1%, moderate/severe pain by 36.3%, and persistent pain by 14.5%. Catastrophizing mean score was 2.15 ± 1.24. Catastrophizing patients showed a 2.90 relative risk (RR) for perineal pain (95% CI: 1.08-7.75) and RR: 1.31 for developing persistent perineal pain (95% CI: 1.05-1.64). They also showed a RR: 2.2 for developing acute and severe perineal pain (95% CI: 1.11-4.33). CONCLUSIONS: The incidence of acute and persistent perineal pain after vaginal delivery is high. Catastrophizing pregnant women are at increased risk for developing acute and persistent perineal pain, as well as severe pain. Perineal trauma increased the risk of persistent perineal pain.
