Resumo

JUSTIFICATIVA E OBJETIVOS: Avaliar a efetividade, a analgesia pós-operatória e o grau de satisfação e recomendação das pacientes submetidas à aspiração manual intra-uterina por meio da comparação de duas técnicas anestésicas. MÉTODO: Foram estudadas, prospectivamente, 80 pacientes distribuídas aleatoriamente em dois grupos. Todas receberam midazolam, por via venosa. Em seguida, o Grupo MC recebeu cetamina S(+) por via venosa e o Grupo MP, bloqueio paracervical uterino. Na sala de cirurgia a eficácia da técnica foi avaliada por três observadores (o pesquisador, o obstetra e o residente de obstetrícia) e, após uma hora, foi avaliada por um observador que desconhecia a técnica realizada, a analgesia pós-operatória, os graus de satisfação de recomendação da paciente mediante escala verbal. RESULTADOS: As técnicas mostraram-se eficientes em 95% das pacientes do Grupo MC e 76,7% das pacientes do Grupo MP (p = 0,04). Entre as pacientes do Grupo MC, 67% não apresentaram dor após uma hora, enquanto no grupo MP a porcentagem de pacientes sem dor foi de 33,3% (p < 0,01 e um risco relativo = 2). Ambos os grupos tiveram 90% de satisfação e de recomendação da técnica. CONCLUSÕES: Neste estudo concluiu-se que a anestesia com midazolam e cetamina S(+) foi superior à associação de midazolam com bloqueio paracervical uterino para aspiração manual intra-uterina, tanto com relação à eficácia quanto à analgesia pós-operatória, sob o ponto de vista dos observadores. Na opinião das pacientes o índice de satisfação foi alto com as duas técnicas.

Abstract

BACKGROUND AND OBJECTIVES: The aim of this study was to evaluate the efficacy, postoperative analgesia, the degree of satisfaction of the patients submitted to manual intrauterine aspiration, and whether the patient would recommend the technique, by comparing two anesthetic techniques. METHODS: A prospective study was done with 80 patients divided, randomized, in two groups. All of them received IV midazolam. Afterwards, the MC Group received IV Ketamaine S(+) and the MP Group underwent paracervical uterine block. In the operating room, the efficacy of the technique was evaluated by 3 observers (the researcher, the obstetrician, and the obstetrics resident) and, after one hour, an observer, who did not know which technique had been used, evaluated the postoperative analgesia, and the degree of satisfaction and whether or not the patient would recommend the technique, using a verbal scale. RESULTS: The techniques were effective in 95% of the patients in the MC group and 76.7% of the patients in the MP group (p = 0.04). Among the patients in the MC group, 67% did not experience pain after 1 hour, while in the MP group the percentage of pain free patients was 33.3% (p < 0.01, and a relative risk = 2). Both groups had a 90% satisfaction rate and 90% would recommend the technique. CONCLUSIONS: We concluded that anesthesia with midazolam and ketamine S(+) was better than the association of midazolam with uterine paracervical block for manual intrauterine aspiration, regarding both efficacy and postoperative analgesia. The index of satisfaction was very high for both techniques.
