The purpose of this study was to analyze the mortality and its prognostic factors in a Spanish cohort of very low birthweight (VLBW) infants during the period 2002 to 2005. Using the Spanish Society of Neonatology database (SEN 1500), 8942 infants with a birthweight < 1500 g were recruited. The overall mortality was 17.3%. However, this incidence underwent a significant decrease over the study period, from 19.4% in 2002 to 15.2% in 2005 ( P = 0.003). Mortality ranged from 12.4% in 25% of the participating neonatal units to 19.4% in a further 25%. Mortality was higher in outborn infants (25.8%) than in inborn infants (16.6%) ( P < 0.001). The mortality rates of these neonates are also presented by 100-g intervals (401 to 1500) and for the different hospitalization times: in the delivery room, within 24 hours and 28 days of birth, at 36 weeks of postmenstrual age, and on discharge. Of note was that mortality was greatest within 24 hours and 28 days of birth in each of the weight groups ( P < 0.001). In conclusion, in the cohort of infants < 1500 g examined, mortality in the period from 2002 to 2005 was still high, especially among newborns weighing < 1000 g. We did, however, observe a decreasing trend in mortality rates for the participating neonatal units over the 4 study years. Our findings highlight the need to promote intrauterine transport and improve neonatal transport as well as the management of these infants in the delivery room and within the first 28 days of life.
Introduction: The ductus arteriosus is a small fetal structure that connects two large arteries (aorta and pulmonary) but becomes pathological when it is maintained after birth. Morbidities associated with persistent patent ductus arteriosus (PDA) may lead to the conclusion that the best approach is early surgical treatment. However, there is evidence that expectant (more selective) surgical management may reduce the chances of unnecessary surgeries and their risks. Objective: To analyze the clinical and surgical profile of preterm newborns submitted to selective correction surgery of the patent ductus arteriosus. Method: This paper contemplates a series of cases, in which all patients submitted to the surgical treatment of PDA in preterm infants were described retrospectively (2009-2016), through the analysis of medical records of the Santa Marcelina Hospital, SP-Brazil. Results: During this period, there were 13 cases of premature infants who underwent selective surgical correction of PDA. Gestational age was 26.92 weeks, maternal age ranged from 15 to 44, birth weight varied between 650 and 1500g, mostly women (61.54%). The diameter of the ductus arteriosus ranged from 1.7 to 4.1 mm, four patients had complex congenital heart disease (30.77%). The median courses of indomethacin were 1.77, congestive heart failure was shown in 11 patients (84.62%), the median age at surgery was 27.69 days and the median duration of orotracheal intubation was 22.62 days. The weight of the newborns at the time of the surgical act varied between 900 and 1820g. The postoperative complications were mostly infectious, with nine patients with bronchopneumonia (69.23%), one patient had pneumothorax. Sepsis occurred in two cases (15.35%) that died due to the same complication (15.35%). Conclusion: All preterm newborns who underwent surgery had birth weight less than 1500g. The median arterial canal was 3.05 mm in diameter. The median gestational age was 26.92 weeks and 62% of the cases were female. The most frequent surgical technique was the triple clipping, there was no bleeding or reoperation in this series of cases. ge at surgery was 27.69 days and the median duration of orotracheal intubation was 22.62 days.
