Perineural Administration of Dexmedetomidine in Axillary Brachial Plexus Block Provides Safe and Comfortable Sedation : A Randomized Clinical Trial
Publisher Copyright: Copyright © 2022 Rocans, Ozolina, Andruskevics, Narchi, Ramane and Mamaja.Dexmedetomidine prolongs the duration of regional block while its systemic sedative effect when administered perineurally is unknown. We aimed to evaluate the systemic sedative effect of perineural dexmedetomidine in patients after axillary brachial plexus block (ABPB). This single-blinded prospective randomized control trial included 80 patients undergoing wrist surgery receiving ABPB. Patients were randomized into two groups – Control group (CG, N = 40) and dexmedetomidine group (DG, N = 40). Both groups received ABPB with 20 ml of 0.5% Bupivacaine and 10 ml of 2% Lidocaine. Additionally, patients in DG received 100 mcg of dexmedetomidine perineurally. Depth of sedation was evaluated using Narcontrend Index (NI) and Ramsay Sedation Scale (RSS) immediately after ABPB and in several time points up to 120 min. Duration of block as well as patient satisfaction with sedation was evaluated using a postoperative survey. Our results showed that NI and RSS statistically differed between groups, presenting a deeper level of sedation during the first 90 min in DG compared to controls, P < 0.001. In the first 10 to 60 min after ABPB the median RSS was 4 (IQR within median) and median NI was 60 (IQR 44–80) in DG group, in contrast to CG patients where median RSS was 2 (IQR within median) and median NI was 97 (IQR 96–98) throughout surgery. The level of sedation became equal in both groups 90 and 120 min after ABPB when the median NI value was 98 (97–99) in DG and 97.5 (97–98) in CG, P = 0.276, and the median RSS was 2 (IQR within median) in both groups, P = 0.128. No significant intergroup differences in hemodynamic or respiratory parameters were found. Patients in DG expressed satisfaction with sedation and 86.5% noted that the sensation was similar to ordinary sleep. In DG mean duration of motor block was 13.5 ± 2.1 h and sensory block was 12.7 ± 2.8 h which was significantly longer compared to CG 6.3 ± 1.5 h, P < 0.001 and 6.4 ± 1.8 h, P < 0.001. We found that beside prolongation of analgesia, perineural administration of dexmedetomidine might provide rather safe and comfortable sedation with no significant effect on hemodynamic or respiratory stability and yields a high level of patient satisfaction.publishersversionPeer reviewe
O ethos e o pathos na sala de parto
RESUMO Objetivo Compreender o ethos e o pathos presentes nos discursos de mulheres parturientes e profissionais de saúde no contexto da sala de parto. Método Pesquisa qualitativa do tipo interpretativa. Utilizou-se o método da Análise do Discurso. Participaram das entrevistas 36 mulheres e 24 profissionais de saúde de maternidades do interior de Minas Gerais. Resultados Os discursos sinalizam a concepção que as mulheres têm do parto, centrada no olhar do outro e nas suas representações; as dificuldades das enfermeiras para operacionalizar o cuidado e construir uma imagem profissional autônoma. O discurso médico enfatiza a especialidade, a capacidade de intervir em situações de risco e as mudanças no status da profissão. Conclusões A construção do ethos de médicos e enfermeiros é fundamental para o delineamento de campos de saberes mais flexíveis e parauma atuação profissional condizente com os seus papéis e comprometida com os preceitos éticos e legais do cuidado obstétrico
