ABSTRACT
Abstract Introduction Controlled hypotension is a reversible procedure in which the patient's baseline mean arterial blood pressure is reduced by 30% and sustained at 60-70 mmHg during the procedure. It decreases blood loss and provides clear surgical field during the procedures. Objectives The purpose of this study was to compare the efficacy of controlled hypotension agents esmolol, remifentanil, and nitroglycerin in functional endoscopic sinus surgery, in terms of hemodynamic changes and impact on the surgical efficiency. Methods The research was carried out as a cohort study. Patients who underwent functional endoscopic sinus surgery were randomized into 3 groups. Controlled hypotension was achieved with remifentanil (Group R), esmolol (Group E) and nitroglycerin (Group N). The efficacy of the drugs was tested by comparing the length of time with the targeted mean arterial pressure, the amount of anesthetics used, surgical field bleeding score and surgeon's satisfaction. Results Between May to December 2015, 60 patients were included and randomized equally into 3 different study groups. The median of the length of time with the targeted mean arterial pressure was shorter in the Group R when compared with Group E (p = 0.01) and Group N (p = 0.14). The amount of volatile anesthetics used was 25.0 mL (15-51), 43.0 mL (21-105) and 40.0 mL (26-97) in Groups R, E and N, respectively (p < 0.001). While there was more bleeding with nitroglycerin, surgical field bleeding scores were lower in Group R when compared with esmolol (p = 0.001) and nitroglycerin (p < 0.001). The analysis of surgeon's satisfaction scores concluded that surgeons were more satisfied with the group R (100%), when compared with group E (60%) and group N (30%) (p < 0.001). Conclusion Less volatile agent, short time to achieve controlled hypotension, stable blood pressure, lower surgical field bleeding scores and larger length of time with the targeted mean arterial pressure were found as the advantages of Remifentanil. Less costly, efficiency of achieving the targeted median arterial pressure and less postoperative complications were the advantages of nitroglycerin. In functional endoscopic sinus surgery procedures, appropriate controlled hypotensive agents should be selected according to the patients' characteristics and advantages/disadvantages of the drugs.
RESUMO
Resumo Introdução Hipotensão controlada é um procedimento reversível no qual a pressão arterial média basal do paciente é reduzida em 30% e mantida em 60-70 mmHg durante o procedimento. Isso diminui a perda de sangue e propicia um campo cirúrgico limpo durante os procedimentos. Objetivo Comparar agentes usados para hipotensão controlada esmolol, remifentanil e nitroglicerina em cirurgia sinusal endoscópica funcional, em termos de alterações hemodinâmicas e impactos na eficácia cirúrgica. Método O estudo foi feito como de coorte. Pacientes submetidos à cirurgia sinusal endoscópica funcional foram randomizados em 3 grupos. A hipotensão controlada foi feita com remifentanil (Grupo R), esmolol (Grupo E) e nitroglicerina (Grupo R). A eficácia dos medicamentos foi testada com a comparação do período de tempo com a pressão arterial média desejada, a quantidade de anestésicos usados, o escore de sangramento no campo cirúrgico e a satisfação do cirurgião. Resultados Entre maio e dezembro de 2015, 60 pacientes foram incluídos e randomizados igualmente nos três grupos de estudo. A mediana do período com a pressão arterial desejada foi menor no Grupo R quando comparado ao Grupo E (p = 0,01) e Grupo N (p = 0,14). A quantidade de anestésicos voláteis usados foi de 25,0 mL (15 ± 51), 43,0 mL (21 ± 105) e 40,0 mL (26 ± 97) nos Grupos R, E e N, respectivamente (p < 0,001). Houve mais sangramento com nitroglicerina e escores de sangramento no campo cirúrgico foram menores no Grupo R quando comparados com esmolol (p = 0,001) e nitroglicerina (p < 0,001). A análise dos escores da satisfação do cirurgião concluiu que os cirurgiões estavam mais satisfeitos com o grupo R (100%) quando comparados ao grupo E (60%) e o grupo N (30%) (p < 0,001). Conclusão Agente menos volátil, pouco tempo para obter a hipotensão controlada, pressão arterial estável, menor escore de sangramento no campo cirúrgico e período de pressão arterial desejada curto foram considerados como vantagens do remifentanil. Menor custo, eficácia de obtenção da pressão arterial média desejada e menos complicações pós-operatórias foram as vantagens da nitroglicerina. Nos procedimentos de cirurgia sinusal endoscópica funcional, os agentes apropriados para obtenção de hipotensão controlada devem ser selecionados de acordo com as características dos pacientes e as vantagens/desvantagens dos fármacos.
