Background and objectives: We aimed to evaluate the effect of bupivacaine and dexmedetomidine added to bupivacaine used in tranversus abdominis plane (TAP) block on postoperative pain and patient satisfaction in patients undergoing lower abdominal surgery. Methods: Patients submitted to lower abdominal surgery were enrolled in the study. After anesthesia induction, ultrasound guided TAP block was performed. TAP block was obtained with 21 mL 0.9% saline in Group C (n = 31), 20 mL 0.5% bupivacaine + 1 mL saline in Group B (n = 31), and 20 mL 0.5% bupivacaine + 1 mL dexmedetomidine (100 μg) in Group BD (n = 31). Results: Visual analog scale scores were lower in Group BD compared to Group C, at all time points (p < 0.05); it was lower in group BD than in group B at 10–24 h. In Group B, it was lower than Group C at 2–8 h (p < 0.05). Total morphine consumption was lower in Group BD compared to other groups and lower in group B than in the controls (p < 0.001). Patient satisfaction was higher in Group BD than in other groups and was higher in both study groups than in the controls (p < 0.001). Nausea-vomiting scores, antiemetic requirement, or additional analgesic administration were not significant among groups (p > 0.05). Conclusions: The addition of dexmedetomidine to bupivacaine on TAP block decreased postoperative pain scores and morphine consumption; it also increased patient satisfaction in patients undergoing lower abdominal surgery. Dexmedetomidine did not have any effect on nausea and vomiting score and antiemetic requirement. Resumo: Justificativa e objetivos: O objetivo do estudo foi avaliar o efeito de bupivacaína e dexmedetomidina adicionada à bupivacaína para bloqueio do plano transverso abdominal (TAP) no controle da dor e satisfação do paciente após cirurgia abdominal inferior. Métodos: Pacientes submetidos à cirurgia abdominal inferior foram incluídos no estudo. Após a indução da anestesia, o bloqueio TAP guiado por ultrassom foi realizado com 21 mL de solução salina a 0.9% no Grupo C (n = 31), 20 mL de bupivacaína a 0,5% + 1 mL de solução salina no Grupo B (n = 31) e 20 mL de bupivacaína a 0,5% + 1 mL de dexmedetomidina (100 μg) no grupo BD (n = 31). Resultados: Os escores da escala visual analógica foram menores no Grupo BD comparado ao Grupo C em todos os tempos mensurados (p < 0,05); foi menor no Grupo BD que no Grupo B em 10-24 horas. No Grupo B, os escores VAS foram menores que no Grupo C em 2-8 horas (p < 0,05). O consumo total de morfina foi menor no Grupo BD em comparação com outros grupos e menor no Grupo B que nos controles (p < 0,001). A satisfação do paciente foi maior no Grupo BD que nos outros grupos e maior em ambos os grupos de estudo que nos controles (p < 0,001). Os escores de náusea e vômito, necessidade de antiemético ou de analgésicos adicionais não foram significativos entre os grupos (p > 0,05). Conclusões: A adição de dexmedetomidina à bupivacaína em bloqueio TAP reduziu os escores de dor e o consumo de morfina no pós-operatório, além de aumentar a satisfação em pacientes submetidos à cirurgia abdominal inferior. Dexmedetomidina não apresentou efeito sobre os escores de náusea e vômito e a necessidade de antiemético.
