Resumo

JUSTIFICATIVA E OBJETIVOS: Fragmentos de pele durante punções subaracnóideas podem desenvolver tumores epidermoides intraespinais. O objetivo deste estudo foi verificar a incidência de células epiteliais que refluem junto com a primeira e terceira gotas de líquor de pacientes submetido a raquianestesia. MÉTODO: Foram obtidas amostras da primeira e terceira gotas de líquor em 39 pacientes adultos submetidos à raquianestesia com agulha 25G Quincke, sendo confeccionadas quatro lâminas: da primeira gota, da terceira gota, da agulha e uma quarta lâmina controle com uma gota de soro fisiológico. As lâminas foram examinadas de forma randomizada pelo patologista. RESULTADOS: Foram identificadas células epiteliais escamosas em 35 (89,7%) das amostras da primeira gota, em 34 (87,2%) da terceira gota e em 24 (61,5%) das agulhas espinais. A terceira gota apresentou em média maior número de células que a primeira gota (p = 0,046). Células epiteliais nucleadas foram encontradas em uma (2,56%) das amostras da primeira gota, em quatro (10,25%) da terceira gota e em uma (2,56%) das agulhas espinais. A terceira gota apresentou em média maior número de células nucleadas que a primeira gota sem diferença estatística (p = 0,257). CONCLUSÕES: Encontramos uma alta porcentagem de células epiteliais que refluem na primeira (89,7%) e na terceira (87,2%) gotas do líquor e nas agulhas utilizadas (61,5%). Mesmo utilizando agulhas de pequeno calibre, descartáveis e com mandril bem adaptado, foram encontradas células da pele.

Abstract

BACKGROUND AND OBJECTIVES: Skin fragments during lumbar punctures may develop intraspinal epidermoid tumors. The aim of this study was to determine the incidence of epithelial cells that reflow along with the first and third drops of CSF of patients undergoing spinal anesthesia. METHODS: Samples of the first and third drops of cerebrospinal fluid were collected from 39 adult patients undergoing spinal anesthesia with a 25G Quincke needle. Four microscope slides were prepared: one for the first drop, one for third drop, one for the needle, and one with a drop of saline for control. A pathologist examined the slides randomly. RESULTS: Squamous epithelial cells were identified in 35 (89.7%) samples from the first drop, 34 (87.2%) from the third drop, and 24 (61.5%) from spinal needle. The third drop showed a mean number of cells larger than the first drop (p = 0.046). Nucleated epithelial cells were found in a sample of the first drop (2.56%), in four samples of third drop (10.25%), and in one spinal needle (2.56%). Third drop showed a mean number of nucleated cells higher than first drop with no statistical difference (p = 0.257). CONCLUSIONS: High percentage of epithelial cells was found in the first (89.7%) and third (87.2%) drops of CSF reflow and in used needles (61.5%). Skin cells were found even using small gauge disposable needles with well-adapted mandrel,
