Abstract Background and objectives: Preoperative instruction is known to significantly reduce patient anxiety before surgery. The present study aimed to investigate the effects of preoperative education on the level of anxiety of cancer patients undergoing surgery using the self-reported Beck anxiety inventory. Methods: This study is a short-term observational study, including 72 female patients with a diagnosis of endometrial cancer who were scheduled to undergo surgical treatment under general anesthesia. During the pre-anesthetic consultation 15 days before surgery, one group of patients (Group A, n = 36) was given comprehensive information about their scheduled anesthetic and surgical procedures, while the other group of patients (Group B, n = 36) did not receive any information pertaining to these variables. The Beck anxiety inventory, blood pressure and heart rate were evaluated before and after the preoperative education in Group A. In Group B, these parameters were evaluated at the beginning and at the end of the consultation. Results: The hemodynamic values were lower in the group that received preoperative education, in comparison with the group that did not receive preoperative education. Educating the patients about the procedure resulted in a reduction in the levels of anxiety from mild to minimum, whereas there was no change in the group that did not receive the preoperative education. This latter group kept the same level of anxiety up to the end of pre-anesthetic consultation. Conclusions: Patient orientation in the preoperative setting should be the standard of care to minimize patient anxiety prior to surgery, especially for patients with cancer.

Resumo: Justificativa e objetivos: A informação transmitida no pré-operatório é conhecida por reduzir de modo significativo a ansiedade do paciente antes da cirurgia. O presente estudo teve como objetivo investigar os efeitos da orientação pré-operatória sobre o nível de ansiedade de pacientes com câncer submetidos à cirurgia, utilizando o inventário Beck de ansiedade. Métodos: Estudo observacional de curto prazo, incluindo 72 pacientes do sexo feminino com diagnóstico de câncer endometrial, programadas para receber tratamento cirúrgico sob anestesia geral. Durante a consulta pré-anestésica, 15 dias antes da cirurgia, um grupo de pacientes (Grupo A, n = 36) recebeu informações abrangentes sobre seus procedimentos anestésicos e cirúrgicos, enquanto o outro grupo de pacientes (Grupo B, n = 36) não recebeu qualquer informação referente a essas variáveis. O inventário Beck de ansiedade, a pressão arterial e a frequência cardíaca foram avaliados antes e após a transmissão de informações ao Grupo A. No Grupo B, esses parâmetros foram avaliados no início e no final da consulta. Resultados: Os valores hemodinâmicos foram menores no grupo que recebeu informação pré-operatória, em comparação com o grupo que não recebeu informação pré-operatória. Informar os pacientes sobre o procedimento resultou em uma redução dos níveis de ansiedade de leve a mínimo, enquanto não houve mudança no grupo que não recebeu informação pré-operatória. Esse último grupo manteve o mesmo nível de ansiedade até o final da consulta pré-anestésica. Conclusões: A orientação do paciente no período pré-operatório deve ser o atendimento padrão para minimizar a ansiedade dos pacientes antes da cirurgia, especialmente os pacientes com câncer.
