Resumo: | Background: To compare the efectiveness of 550 mg naproxen sodium versus 6 mL 2%-lidocaine intracervical block in pain lowering at the 52-mg levonorgestrel-releasing intrauterine system (LNG-IUS) placement in young women. Methods: In this randomized controlled trial, 100 women aged 15–24 years were block-randomized to receive either 6 mL 2%-lidocaine intracervical block 5 min before the LNG-IUS insertion or 550 mg naproxen 30 min before the procedure. Forty-nine women received 550 mg naproxen and 51 received intracervical block. The primary outcome was pain at LNG-IUS insertion. Secondary outcomes were ease of insertion, insertion failures, and correct IUS positioning. Neither participants nor doctors were blinded. Pain at insertion was assessed by using a Visual Analog Scale (VAS). Results: Women randomized to lidocaine intracervical block presented lower mean pain score at insertion, when compared to women who received naproxen (5.4 vs. 7.3, respectively; p<0.001). Parous women had a 90.1% lower chance of experiencing severe pain (p=0.004). There was a 49.8% reduction in the chance of severe pain for every 1-cm increase in the hysterometry (p=0.002). The only complication observed during insertion was vasovagal-like reactions (7%). The insertion was performed without difculty in 82% of the women. Participants in the intracervical block group presented higher proportion of malpositioned IUS on transvaginal ultrasound examination compared to women in naproxen group. Nevertheless, all the malpositioned IUS were inserted by resident physicians. Conclusion: Lidocaine intracervical block was found to be more efective than naproxen in reducing LNG-IUS insertion pain. |

Métodos: Neste estudo controlado randomizado, 100 mulheres com idades entre 15 e 24 anos foram randomizadas em bloco para receber 6 mL de lidocaína a 2% em bloqueio intracervical 5 minutos antes da inserção do SIU-LNG ou 550 mg de naproxeno 30 minutos antes do procedimento. Quarenta e nove mulheres receberam 550 mg de naproxeno e 51 receberam bloqueio intracervical. O desfecho primário foi dor na inserção do SIU-LNG. Os resultados secundários foram facilidade de inserção, falhas de inserção e posicionamento correto do SIU. Nem os participantes nem os médicos foram cegados. A dor na inserção foi avaliada por meio de uma Escala Visual Analógica (VAS). Resultados: As mulheres randomizadas para o bloqueio intracervical com lidocaína apresentaram menor média de dor na inserção, quando comparadas às mulheres que receberam naproxeno (5,4 vs. 7,3, respectivamente; p<0,001). As parturientes tiveram 90,1% menos chance de sentir dor intensa (p=0,004). Houve redução de 49,8% na chance de dor intensa para cada aumento de 1 cm na histerometria (p=0,002). A única complicação observada durante a inserção foram reações do tipo vasovagal (7%). A inserção foi realizada sem dificuldade em 82% das mulheres. As participantes do grupo bloqueio intracervical apresentaram maior proporção de SIU mal posicionado na ultrassonografia transvaginal em comparação com as mulheres do grupo naproxeno. No entanto, todos os SIU mal posicionados foram inseridos por médicos residentes. Conclusão: O bloqueio intracervical com lidocaína foi mais eficaz do que o naproxeno na redução da dor de inserção do SIU-LNG.engUniversidade Federal de Minas GeraisUFMGBrasilHCL - HOSPITAL DAS CLINICASMED - DEPARTAMENTO DE GINECOLOGIA OBSTETRÍCIABMC Women's HealthDorDispositivos intrauterinosAdolescenteNaproxenoLidocaínaPain reliefIntrauterine contraceptionIntrauterine deviceAdolescentNulliparousIUD insertion painUse of naproxen versus intracervical block for pain control during the 52-mg levonorgestrel-releasing intrauterine system insertion in young women: a multivariate analysis of a randomized controlled trialUso de naproxeno versus bloqueio intracervical para controle da dor durante a inserção do sistema intrauterino liberador de levonorgestrel 52 mg em mulheres jovens: uma análise multivariada de um estudo randomizado controladoinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://bmcwomenshealth.biomedcentral.com/articles/10.1186/s12905-021-01521-zElaine Cristina Fontes de OliveiraThaís BaêtaAna Paula Caldeira BrantAgnaldo Lopes da Silva FilhoAna Luiza Lunardi Rochaapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain;

The only complication observed during insertion was vasovagal-like reactions (7%). The insertion was performed without difculty in 82% of the women. Participants in the intracervical block group presented higher proportion of malpositioned IUS on transvaginal ultrasound examination compared to women in naproxen group. Nevertheless, all the malpositioned IUS were inserted by resident physicians.
