INTRODUCTION: The major advances in neonatal intensive care have made less useful the Waterston's criteria for @entity1152 ( @entity1152 ) and/or @entity4501 ( @entity4501 ), and other prognostic classifications have been reported. The aim of this study was to determine the influence of various parameters on the outcome of @entity20434 . MATERIAL AND METHODS: We reviewed 97 cases admitted in our hospital for 29 years. We divided the cases in two groups in relation to the improvement of our neonatal unit care during the years: 1st. 1971-1982 (n = 46); 2nd. 1983-1999 (n = 51). chi 2 squared test and logistic regression analysis of the influence of several parameters before surgical treatment (Waterston's and Spitz's birth weight groups, @entity55 , @entity734 , severity of @entity154 and @entity299 ) on mortality was performed. RESULTS: The survival rate increased since 1983, reaching 86.2% in the last 10 years, although the number of neonates with birth weight < 1500 g has increased. Association with a @entity154 increased the mortality significantly in the 2nd. group only (45.5% major vs 7.1% minor and 8.3% none). The @entity299 were the most common, not only before 1983 (26.8%), but also since then (31.3%). When the neonate associated a major @entity299 the mortality was significantly higher in the 2nd. group (71.4%). The mortality, when @entity55 was present, was significantly higher before 1983 only (75% vs 32.4%), whereas the mortality was significantly increased by the need of ventilator in the 2nd. group only (85.7% vs 9.1%). Before 1983, the best prognostic parameters were the @entity55 and the severity of @entity154 , whereas only the @entity734 was selected between 1983 and 1999. CONCLUSIONS: The @entity20434 mortality has decreased in the last years. The associated @entity299 is the most common. We think that the @entity734 is the most reliable prognostic risk factor, showing a poor physiologic status of the neonate.
