Resumo

JUSTIFICATIVA E OBJETIVOS: Os desfechos clínicos de bloqueios anestésicos regionais periféricos nem sempre são os esperados. Ora resultam insuficientes, ora superdimensionados. Para o entendimento e aprendizado desses fenômenos, os meios de rádio-imagem tornam-se esclarecedores. O objetivo deste estudo foi demonstrar os diferentes trajetos e distribuições, respectivamente, de cateteres e de soluções anestésicas (anestésico local com contraste), utilizados em bloqueios regionais de membros superior e inferior. RELATO DOS CASOS: São apresentados três casos de bloqueios regionais periféricos, em que os efeitos clínicos inesperados foram esclarecidos por imagens radiográficas contrastadas. CONCLUSÕES: Com o intuito de certificar a posição de cateteres e esclarecer os efeitos anestésicos inesperados, os estudos de rádio-imagens contrastadas são de grande utilidade, pois correlacionam dispersões imprevisíveis de soluções anestésicas com sintomas e sinais dos bloqueios periféricos.

Abstract

BACKGROUND AND OBJECTIVES: The clinical results of regional peripheral blockades are not always what we hope for. Sometimes the results are short of our intent and sometimes are exaggerated. To understand and learn those phenomena, radioimaging techniques are very helpful. The objective of this study is to demonstrate the different trajectories and distribution of catheters and anesthetics (local anesthetic with contrast), respectively, used in regional blockades of the upper and lower limbs. CASE REPORTS: Three cases of peripheral regional blockade, in which unexpected clinical effects were solved using contrast X-rays, are presented. CONCLUSIONS: Contrast X-rays are very useful to verify the position of catheters and solve unexpected anesthetic effects, because they are able to relate the unpredictable dispersion of anesthetics to the signs and symptoms of peripheral blockades.
