Avaliação da bupivacaína hipobárica a 0,5% na raquianestesia

Abstract: RESUMOSantos MCP, Kawano E, Vinagre RCO, Noé RAM -Avaliação da Bupivacaína Hipobárica a 0,5% na Raquianestesia. JUSTIFICATIVA E OBJETIVOS:A raquianestesia causa alterações hemodinâmicas relacionadas com fatores próprios do paciente ou não. Um dos fatores é a densidade do anestésico em relação ao líquor, interferindo no número de dermátomos bloqueados e, conseqüentemente, no nível do bloqueio simpático e na diminuição da pressão arterial (PA). O objetivo do estudo foi avaliar a dispersão da bupivacaína hipobári… Show more

“…However, if adjuvant administration causes a substantial change in LA-A’s relative baricity, it will result in a clinically different block distribution [ 23 ]. Although hypobaric solutions are used in anorectal surgery or unilateral blocks to potentially reduce the hemodynamic effects of a sympathetic block, their administration in the common sitting position used in our institution may result in higher spread and potentially more prominent features of a sympathetic block [ 24 , 25 , 26 ].…”
