Incidência de disfagia orofaríngea após acidente vascular encefálico em hospital público de referência

A doença vascular encefálica (AVE) é a principal causa de morte no Brasil. As seqüelas em indivíduos pós-acidente vascular encefálico incluem distúrbios motores, distúrbios de fala ou de linguagem e distúrbios de deglutição. A disfagia orofaríngea ocorre em cerca de 50% dos pacientes com AVE. Este estudo teve por objetivo determinar a incidência da disfagia após AVE. Foram avaliados todos os pacientes que deram entrada em hospital universitário de referência no período de um ano, tão logo apresentassem condições para avaliação clínica, fonoaudiológica e neurológica (102 pacientes), com análise objetiva da deglutição (61 pacientes). Foi observada incidência de disfagia em 76,5% dos pacientes avaliados clinicamente, este percentual elevando-se a 91% com avaliação videofluoroscópica. A alta incidência de disfagia observada neste estudo que avaliou pacientes com amplo espectro de gravidade, em diferentes fases de recuperação, ressalta a importância de equipe multidisciplinar, incluindo fonoaudiólogos capacitados, para avaliar os distúrbios da deglutição nos diversos momentos de recuperação dos AVEs.

Cauda equina syndrome after spinal tetracaine: Electromyographic evaluation-20 years follow-up

CAUDA equina syndrome (CES) has long been recognized as a rare complication of spinal anesthesia.(1) CES has been described after administration of spinal anesthetics with lidocaine(2) and bupivacaine.(3) In 1991,(4) CES was reported after continuous spinal anesthesia with 1% tetracaine. In 1980, at our university hospital, six adult female patients underwent perineal gynecologic surgery using a spinal anesthetic of 2 ml tetracaine, 1.2%, in 10% glucose. The concentration of the injected tetracaine was unknown by the anesthetists. In all cases, lumbar puncture was performed at the L3-L4 interspace with a disposable spinal needle while the patients were in the sitting position. CES was first diagnosed 72 h or later postoperatively; previous diagnosis was not possible because patients had an indwelling urethral catheter. The diagnosis of CES was confirmed in all patients. During the past year, after institutional approval and informed consent, clinical, magnetic resonance imaging, electromyographic examinations, and conduction studies were performed in three of the above patients. Examinations were not possible on the other three patients because one had recently died, another could not be located, and the third refused to participate. T1 and T2 magnetic resonance image readings were obtained with Gadolinium contrast from a 0.5 Tesla General Electric apparatus (General Electric, Tokyo, Japan). Bilateral sensory and motor conduction studies of the sciatic nerve branches were obtained using a two-channel Nihon-Kohden Neuropack 2 (Nihom-Kohden Corporation, Tokyo, Japan). Electromyography was performed in accordance with conventional techniques.(5,6)
