Resumo
Este estudo teve como objetivo identificar a ocorrencia de obstrucao de sonda nasoenteral e a existencia de associacao com as variaveis: formulacao da nutricao enteral, associacao de formulas, infusao da nutricao enteral administracao de medicamentos e procedimentos de suporte terapeutico. Trata-se de pesquisa quantitativa, descritiva e prospectiva, realizada na Unidade de Terapia Intensiva e Unidade Coronaria de um hospital particular, especializado em cardiologia, do Municipio de São Paulo. A amostra constituiu-se de 60 pacientes submetidos, ou nao, a procedimentos cirurgicos, com prescricao de terapia nutricional enteral por infusao continua atraves de sonda nasoenteral calibre 8 French. Em razao do pequeno tamanho da amostra, utilizou-se o teste exato de Fisher (p=0,05) para verificar a existencia, ou nao, de associacao das variaveis selecionadas e o evento estudado. Os resultados do estudo evidenciaram a ocorrencia de obstrucao da sonda nasoenteral em cinco pacientes (8,3 por cento) e que as variaveis diminuicao do fluxo da nutricao enteral pela bomba infusora e dificuldade para irrigar a sonda nasoenteral associaram-se estatisticamente a esse evento. Embora os pacientes tenham recebido diversos tipos de medicamentos pela sonda nasoenteral e que um volume menor de agua tenha sido usado para a manutencao da perviedade da sonda em decorrencia da cardiopatia, o numero de ocorrencias de obstrucao situou-se dentro da faixa descrita na literatura. Conclui-se, entao que: a ocorrencia de obstrucao da sonda nasoenteral na amostra foi de 8,3 por cento sendo que, somente a diminuicao do fluxo da nutricao enteral pela bomba infusora e a dificuldade para irrigar associaram-se estatisticamente com obstrucao da sonda nasoenteral. Considerou-se que a instituicao de um protocolo para manutencao da perviedade da sonda foi uma pratica decisiva para a reduzida ocorrencia de obstrucao da sonda nasoenteral
This study had as objective to assess the occurrence of enteral feeding tube blockage and to determine any possible association between this event and the variables: enteral nutrition formulation, association of formulas, infusion of enteral nutrition and the administration of drugs and procedures of therapeutic support. This study was quantitative, descriptive and prospective carried out in the Intensive Care Unit and in the Coronary Care Unit of a private cardiological hospital in the City of São Paulo. The study group comprised 60 patients – having been operated on or not - receiving enteral nutrition by continual infusion through gauge 8 French enteral feeding tube. Due to the small size of the sample, the exact test of Fisher (p=0.05) was used to determine if the variables focused on were associated with the event studied. Enteral feeding tube blockage occurred for five patients (8.3%) and the statistical analysis showed that the decreased enteral nutrition inflow and the difficulty in washing up the enteral feeding tube were associated with the event. Despite the patients having received various sorts of drugs via enteral feeding tube and a smaller amount of water having been used to guarantee the free passage through the tube, the number of blockage occurrences was within the range described in the literature. This study shows as conclusions a blockage rate of 8.3% in the study sample and the finding that the decreased feeding inflow and the difficulty in washing-up the tube were statistically associated with the blockage of the feeding tube. The adoption of a protocol for washing-up the enteral feeding tube in order to keep the free passage through it is deemed to be a key factor for the small number of occurences of its blockage.
