Resumo

Introdução: A utilização de um simulador de punção venosa, facilita o aprendizado da técnica e aprimora as habilidades, o que diminui o risco de complicações na punção venosa em humanos. Objetivo: Analisar a eficácia de um modelo experimental não humano para punção venosa superficial guiada por ultrassom. Método: Foram randomizados 39 enfermeiros em dois grupos: A e B. O treinamento apresentou três etapas: 1 - aula teórica, 2 - aula prática no aparelho de ultrassonografia e 3 - treinamento de punção guiada por ultrassonografia no modelo não humano. O grupo A participou das etapas 1, 2 e 3 e o grupo B das etapas 1 e 2. Após o treinamento, ambos os grupos foram liberados para punção venosa guiada por ultrassom. Resultados: O sucesso na punção no grupo A (n = 20) foi de 90% e no grupo B (n = 19) foi de 68,42%. Na somatório dos tempos de identificação e de punção, a média no grupo A foi de 61,5 segundos (IC 95% 33,58; 106,95) e no grupo B de 148,0 segundos (IC95% 114,54; 208,44), o que foi estatisticamente significante (p = 0,007, sem sobreposição das estimativas intervalares). Conclusão: As enfermeiras que receberam treinamento com o modelo não humano obtiveram melhores tempos de identificação e de punção da veia.
