RESUMO
Axillary dissection is a standard surgical procedure for stage III skin and soft tissue tumors and is usually performed under general anesthesia. This study aimed to investigate the feasibility of performing axillary dissection with Serratus muscle plane block plus intravenous sedation. Fifteen patients undergoing axillary dissection were prospectively recruited. The patients were evaluated during their pre-operative anesthetic appointment, during their procedure, and at post-operative days 1 and 30. The blockade was performed superficial to the Serratus muscle at the level of fourth rib. Sedation was performed using propofol, fentanyl, dexmedetomidine, and S-ketamine. None of the patients required conversion to general anesthesia. Surgeons showed a highly positive response when asked about the anesthetic technique, and most of them found the technique "indistinguishable" from general anesthesia. The median (interquartile range) pain scores at rest over all time frames was 0 (0-0). Furthermore, no patients developed nausea, hemodynamic instability, or any complications associated with the technique. The Serratus plane block associated with intravenous sedation proved feasible for axillary lymphadenectomy, however, further clinical trials should evaluate potential advantages compared to other techniques.

RESUMO A linfadenectomia axilar é um procedimento cirúrgico padrão para tratamento de tumores de pele e partes moles no estádio III e usualmente é realizada sob anestesia geral. A presente serie de casos prospectiva tem por objetivo investigar a viabilidade da realização da linfadenectomia axilar com o uso do bloqueio do plano do músculo serrátil anterior associado a sedação endovenosa. Foram incluídos 15 pacientes no estudo. Os participantes foram recrutados e avaliados durante consulta pré-anestésica ambulatorial, acompanhados durante o dia da cirurgia, no primeiro e no trigésimo dias de pós-operatório. O bloqueio foi realizado anterior ao músculo serrátil anterior ao nível da quarta costela na linha axilar média. A sedação foi realizada com o uso de propofol, fentanil, dexmedetomidina e dextrocetamina. Não houve necessidade de conversão para anestesia geral em nenhum paciente. Os cirurgiões apresentaram resposta altamente positiva quando questionados sobre a técnica anestésica, considerando na maior parte dos casos "indistinguível" da anestesia geral. A mediana (intervalo interquartil) da dor em repouso em todos os momentos avaliados foi 0 (0-0). Além disso, nenhum paciente desenvolveu náuseas, vômitos, instabilidade hemodinâmica ou qualquer complicação relacionada à técnica empregada. O bloqueio do plano do músculo Serrátil anterior associado a sedação venosa se mostrou viável para execução de linfadenectomia axilar, entretanto ensaios clínicos adicionais são necessários para avaliar potenciais vantagens em comparação com outras técnicas.
