knowledge of this evidence favors planning the care provided by defining strategies to reduce it and consequently improve maternal and infant health care.

Objective: To conduct a cross-cultural adaptation of the Preterm Parenting & Self-Efficacy Checklist to the Brazilian Portuguese. Method: A methodological study was carried out with 51 parents of premature infants. Data analysis was based on psychometric and inferential statistical analyses. Results: The instrument content validation by experts obtained excellent agreement (97%) and the semantic analysis by the target population showed good understanding of the terms and ease of use. In test-retest, most participants were female (64.7%); and parents with higher education (47.1%). The instrument showed stability over time, with good internal consistency (α = 0.84). Four factors were generated in the subscales parenting self-efficacy, importance of tasks and self-perceived parental competence (67.0% to 74.2% of the variance). Conclusion: The properties of the Preterm Parenting & Self-Efficacy Checklist -Brazilian Version were maintained, which is a reliable indicator to evaluate the hospital discharge of premature infants.

Objective: To evaluate the effectiveness of the enteral tube measurement using the modified nose -ear -xiphoid (NEX) technique by disregarding the tube distal orifices for placement in newborns' neonatal gastric cavity. Methods: A prospective study conducted in a neonatal unit of a teaching hospital in the city of São Paulo, based on the radiographic analysis of 60 radiographs of 28 newborns using enteral tubes measured by the modified technique, and who had thoracoabdominal radiography. Results: The correct placement index according to analysis by position was 68.3% and 71.7%, according to evaluators 1 and 2, respectively. In the analysis by vertebrae, 95% of tubes were properly placed in the gastric cavity. There was a statistically significant association between height and location of the enteral tube according to evaluator 2. Conclusion: The evaluated measurement technique presents a risk for inadequate enteral tube placement in newborns, and its application in clinical practice should not be encouraged. ResumoObjetivo: Avaliar a efetividade da mensuração de sonda enteral pela técnica modificada, nariz -orelha -apêndice xifoide, com desconto dos orifícios distais da sonda, para posicionamento na câmara gástrica de neonatos. Métodos: Estudo prospectivo, desenvolvido em unidade neonatal de um hospital de ensino do município de São Paulo, a partir da análise radiográfica de 60 radiografias de 28 neonatos em uso de sonda enteral mensurada pela técnica modificada, submetidos à radiografia toracoabdominal. Resultados: O índice de posicionamento correto, de acordo com a análise por posições, foi de 68,3% e 71,7%, segundo os avaliadores 1 e 2, respectivamente, enquanto na análise por vértebras, 95% das sondas estavam adequadamente locadas na câmara gástrica. Ocorreu associação estatisticamente significante entre estatura e localização da sonda enteral, segundo o avaliador 2. Conclusão: A técnica de mensuração avaliada apresenta risco para posicionamento inadequado da sonda enteral utilizada em neonatos, devendo ser desencorajada sua aplicação na prática clínica.
