RESUMO

The quality improvement on newborns intensive care leaded to higher levels for premature babies survival rates. The bigger preoccupation doesnt regard simply their survival, but further on, regards quality of life. This study has the main objective to typify the neurobehavioral development on preterm born babies, before the 40th week of post-conceptional age. As specific objectives: a) to compare neurobehavioral performance of this studys sample to the original standard sample of NAPI test; b) to parallel indicators of neurobehavioral development in groups classified according to perinatal problems; c) to compare neurobehavioral development indicators from groups created according the gender. The sample has been composed of 202 preterm infants (gestational age 37 weeks), both genders, underweight (<2500 g), clinically stable and on therapy at the Neonatal Intensive Care Unit or Intermediary Care Nursery of the Goiânias Hospital Materno-Infantil, for the period of September 2004 to January 2006. The following instruments were applied: Neurobehavioral Assessment for the Preterm Infant (NAPI), guide for anamnesis, medical history and a Questionnaire for Socioeconomical Individuation. The procedure for babies evaluation was filmed. The accordance rate among the beholders has been about 88%. The videos analysis had the purpose of rating babies performances according to NAPI. Firstly, data were submitted to descriptive statistic analysis. The discret variances were quantified depending on frequency, prevalence or percentage and continuous variances in terms of medium value and standard deviation, median, minimum and maximum values. Then the comparison of NAPI performances on studys sample and tests standard results, between both genders and two groups (one with perinatal problems PIG, such as anoxia, hemorrhaging and hydrocephalus and another group without any perinatal problem). Results shown meaningful difference between the groups on NAPI basis. The sample of this study (AE) has shown less muscular tonicity at the scarf sign, less vigor and spontaneuos movements, higher alert and orientation regards tests standard group (AT). Furthermore, the the AE group shown lightly weaker crying and higher quantity of sleeping, what means the newborns slept more during the test, regards AT group. When analyzed NAPI general ratings, according standard deviation on tests sample, it was remarkable that the the most of the newborns on study were rated at medium rating, besides around one third of them under that rate. No meaningful statistic difference was verified between boys and girls ratings. The results of neurobehavioral development on groups with and without perinatal problems, regards the standard of the test were simillar on NAPI. The assessment provided data about risk detection on babies born preterm, with the purpose of putting into effect effective measures for preventive intervention to avoid future development problems.
