“…Patent ductus arteriosus was diagnosed echocardiographically and treated when deemed hemodynamically significant by the investigating cardiologist. Criteria for hemodynamically significant patent ductus arteriosus included ductal size >2 mm, left atrium to aortic root diameter of >1.6, and pulsatile flow pattern of patent ductus arteriosus [ 22 ].…”

BackgroundLittle is known about cerebral artery resistive index values in infants born extremely preterm.ObjectiveTo report resistive index values in various cerebral arteries in a prospective cohort of preterm infants born at <29 weeks’ gestation, and to compare resistive index in these arteries and assess the relationship between resistive index and hemodynamically significant patent ductus arteriosus.Materials and methodsUsing Doppler imaging, we obtained resistive index values of internal carotid arteries, basilar artery, anterior cerebral artery, and pial and striatal arteries in the first 3 days of age and weekly thereafter until discharge or death. We analyzed paired observations using the Wilcoxon signed-rank test, between-group comparisons with the Mann–Whitney test.ResultsWe performed 771 examinations in 235 infants. Resistive indices differed among arteries: vessels with larger diameters showed significantly higher resistive indices. Resistive index in infants without patent ductus arteriosus was lower than that in infants with hemodynamically significant patent ductus arteriosus (median in anterior cerebral artery: 0.75 and 0.82, respectively; P<0.001), though this was not statistically significant in all arteries. There was no difference in pre- and post-ligation resistive indices in infants who underwent patent ductus arteriosus ligation.ConclusionFor accurate follow-up and comparison of cerebral artery resistive index, the same artery should be examined on each occasion.

“…Although the frequency of premature rupture of membranes (PROM) was higher in Group 1, the difference was not statistically significant (p > 0.05). Cervical culture were taken a median of five days [2][3][4][5][6][7][8][9][10][11][12][13][14] prior to delivery. The parameters of complete blood count as hemoglobin, white blood cell, and platelets were not different between groups, but the values of acute phase reactants CRP and IL-6 were higher in Group 1, and the difference was statistically significant (for CRP p < 0.05 and for IL-6 p < 0.001, Table 1).…”

“…RDS diagnosis made by typical clinical (grunting, cyanosis, tacypnea), and radiologic finding [8]. NEC was defined according to modified Bell's criteria (≥ Grade 2), and PDA was defined as clinical diagnosis plus treatment with ibuprofen, surgical ligation, or both [9,10]. BPD was defined as requirement for oxygen at 36 weeks' corrected gestational age or at discharge from the participating unit [11].…”

To evaluate and compare the morbidity and mortality of neonates born to pregnant women with positive and negative cervical cultures. Materials and Methods: The demographic and clinical features of mothers included in this study, along with details of the microorganisms isolated on maternal cervical cultures and the number of days between a positive cervical culture and delivery were recorded. Neonates were stratified into two groups based on cervical culture results of their mothers -Group 1, positive cervical culture; Group 2, negative cervical culture. Results: A total of 216 women who delivered 242 infants were included in the study. Group 1 consisted of 90 neonates while Group 2 had 152 newborns. The difference between the groups with demographic characteristics was statistically insignificant. Mean levels of the acute phase reactants, CRP, and IL-6, obtained six hours after delivery were significantly higher in Group 1 compared to Group 2 (p < 0.05 for C-reactive protein (CRP) and p < 0.001 for IL-6). Although there was no difference between groups in terms of duration of respiratory support, mean duration of hospitalization, as well as mortality rate were significantly higher in Group 1 (p < 0.001, p < 0.05, respectively). Conclusions: Women diagnosed with a high-risk pregnancy should be treated with antibiotics immediately after a positive cervical culture result, and delivery should be delayed until the success of antibiotic treatment can be evaluated. Early initiation of maternal antibiotic therapy is associated with shorter durations of hospital stay for newborns. Close follow-up of mothers with high-risk pregnancies and extension of treatment duration are critical for determining prognosis in newborn infants.

“…Echocardiography has become essential for evaluating significant ductal shunting 15 - 17 . Doppler echocardiographic assessment of PDA shunt flow pattern 10 is useful for predicting the development of significant PDA: a growing and pulsatile Doppler flow pattern indicates the risk of developing a clinically significant PDA, whereas a closing or closed pattern is generally associated with a non-significant shunt.…”

OBJECTIVE:Early diagnosis of significant patent ductus arteriosus reduces the risk of clinical worsening in very low birth weight infants. Echocardiographic patent ductus arteriosus shunt flow pattern can be used to predict significant patent ductus arteriosus. Pulmonary venous flow, expressed as vein velocity time integral, is correlated to ductus arteriosus closure. The aim of this study is to investigate the relationship between significant reductions in vein velocity time integral and non-significant patent ductus arteriosus in the first week of life.METHODS:A multicenter, prospective, observational study was conducted to evaluate very low birth weight infants (<1500 g) on respiratory support. Echocardiography was used to evaluate vein velocity time integral on days 1 and 4 of life. The relationship between vein velocity time integral and other parameters was studied.RESULTS:In total, 98 very low birth weight infants on respiratory support were studied. On day 1 of life, vein velocity time integral was similar in patients with open or closed ductus. The mean vein velocity time integral significantly reduced in the first four days of life. On the fourth day of life, there was less of a reduction in patients with patent ductus compared to those with closed patent ductus arteriosus and the difference was significant.CONCLUSIONS:A significant reduction in vein velocity time integral in the first days of life is associated with ductus closure. This parameter correlates well with other echocardiographic parameters and may aid in the diagnosis and management of patent ductus arteriosus.
