Zusammenfassung: | Ultrasound-guided transrectal prostate biopsy is a reference in the diagnosis of prostate neoplasias. The higher the number of samples, the greater is the pain and discomfort. The objective of this study was to compare three anesthetic techniques in this group of patients.
Forty-five patients were included in this study. Patients were divided into three groups: 1 – Propofol; 2 – Propofol + Prostatic Plexus Block; 3 – Propofol + Fentanyl. Patients were monitored with non-invasive blood pressure, continuous electrocardioscopy, pulse oximetry (SpO2), and Bispectral Index. Patients did not receive pre-anesthetic medication. Intraoperative and postoperative hemodynamic parameters, intraoperative bispectral index, and postoperative visual analogue scale (VAS) and the use of dypirone to treat postoperative pain were evaluated.
A significant difference among the three groups was not observed for: anthropometric parameters, amount of propofol, number of fragments, and duration of the exam. Hemodynamic parameters and SpO2 presented similar behavior in all three groups. In group 1, the pain evaluated by the VAS was more severe and required more dypirone than in the other groups.
Sedation with propofol alone for biopsy is associated with greater postoperative pain and discomfort than in prostatic plexus block or systemic fentanyl. Besides hypnosis, intraoperative analgesia is required to guarantee postoperative comfort.
A biópsia de próstata dirigida por ultrassonografia transretal constitui referência no diagnóstico das neoplasias da próstata. Quanto maior o número de amostras colhidas, maiores a dor e o desconforto relatados pelo paciente. O objetivo do estudo foi comparar três técnicas anestésicas neste grupo de pacientes.
Foram estudados 45 pacientes separados em três grupos: 1 – Propofol; 2 – Propofol + Bloqueio de Plexo Prostático; 3 – Propofol + Fentanil. Os pacientes foram monitorados com pressão arterial não invasiva, eletrocardioscopia contínua, oximetria de pulso (SpO2) e Índice Bispectral. Não receberam medicação pré-anestésica. Foram avaliados os parâmetros hemodinâmicos no intra e pós-operatório, Índice bispectral no intraoperatório, avaliação da dor pela escala numérica verbal (ENV) no pós-operatório imediato e uso de dipirona como tratamento da dor pós-operatória.
Não houve diferença significativa entre os três grupos: variáveis antropométricas, quantidade de propofol, número de fragmentos e tempo do exame. Os parâmetros hemodinâmicos e a SpO2 apresent |
