Resumo
JUSTIFICATIVA E OBJETIVOS: A técnica de histerectomia vaginal possibilita menor tempo operatório e o uso do bloqueio do neuro-eixo, com os benefícios de melhor analgesia pós-operatória e menor resposta sistêmica ao procedimento cirúrgico. O objetivo deste relato foi descrever as alterações hemodinâmicas decorrentes do posicionamento em litotomia exagerada em paciente cardiopata. RELATO DO CASO: Paciente de 33 anos, G0P0A0, com história de sangramento uterino anormal e anemia. A ultra-sonografia evidenciava útero miomatoso com volume estimado de 420 cm³. Ela era portadora de trombofilia e miocardiopatia dilatada, com passado de dois acidentes vasculares encefálicos isquêmicos e dois infartos agudos do miocárdio. Foi monitorizada com pressão arterial invasiva e cateter de artéria pulmonar com medida de débito cardíaco contínuo. Realizada raquianestesia com bupivacaína hiperbárica e morfina. A paciente foi posicionada em litotomia exagerada sendo realizada histerectomia total pela técnica de Heaney e salpingectomia bilateral. Como intercorrência intra-operatória apresentou diminuição do índice cardíaco e aumento das pressões de câmaras direitas após o posicionamento, necessitando do uso de dobutamina. CONCLUSÕES: O posicionamento em litotomia exagerada pode ocasionar alterações hemodinâmicas que devem ser consideradas na escolha da técnica cirúrgica.

Abstract
BACKGROUND AND OBJECTIVES: Vaginal hysterectomy shortens surgery duration and may be performed with neuraxial block, which promotes better postoperative analgesia and lower systemic response to surgical procedure. This report aimed at describing hemodynamic changes promoted by exaggerated lithotomy position in cardiac patient. CASE REPORT: Female patient, 33 years old, with history of abnormal uterine bleeding and anemia. Ultrasound revealed myomas of approximately 420 cm³. Patient had thrombophilia and dilated cardiomyopathy, with history of two ischemic strokes and two acute myocardial infarction. Monitoring consisted of invasive blood pressure and pulmonary artery catheter for continuous cardiac output measurement. Spinal anesthesia was performed with hyperbaric bupivacaine and morphine. Patient was placed in exaggerated lithotomy position being total hysterectomy performed by the Heaney technique and bilateral salpingectomy. Intraoperative intercurrences were post-positioning decreased cardiac output and increased right chambers pressure requiring dobutamine. CONCLUSIONS: Exaggerated lithotomy position may promote hemodynamic changes which should be considered when choosing the surgical technique.
