The SFR (Sp02/Fi02 ratio) offers a continuous, non-invasive reflection of pulmonary function regardless of whether the baby is ventilated or breathing spontaneously. We hypothesized that significant PDA shunting would impair pulmonary oxygen diffusion, in turn, reflected by decreased SFR; and that early PDA related decreases in SFR will predict subsequent chronic lung disease (CLD). Methods: We retrospectively examined records from preterm neonates <30 weeks gestational age. Ductal shunting was graded for severity by first week echocardiogram. SFR was calculated as SpO2/Fi02 and recorded on day 7 of life and at 36 weeks postmenstrual age (PMA). Results: We studied 104 infants: 65 with closed duct; 17 with hemodynamically insignificant PDA and 22 with hemodynamically significant (hsPDAs). CLD developed in 9 (14%) of those with closed ducts; 6 (35%) of those with hisPDA; and in 12 (55%) of those with hsPDA (p=0.005). Babies with hsPDA had significantly lower SFR values at both time points. SFRs in babies with hisPDA were decreased at 1 week postnatally, but were similar to those of babies with closed ducts at 36 weeks. SFR at 36 wks. was decreased only in infants with hsPDA [[467[461,467] vs. 467[413,471] vs. 369[262,436] respectively; p=0.000148]. Using ROC curve analysis, week 1 SFR was strongly associated with hsPDA (AUC=0.770; p<0.0001) and highly predictive (AUC=0.801; p<0.0001) of CLD at 36 weeks PMA. Conclusion: Early decreases in SFR reflect both the acute and chronic pulmonary impact of PDA shunting, possibly providing the missing link supporting an association between hemodynamically significant PDA and subsequent CLD.

Background: Patent Ductus Arteriosus (PDA) is considered one of the most prevalent types of congenital heart disease. The closure of the ductus arteriosus physiologically occurs at the first 48-72 hours after the birth in healthy term infants. Different causes can result in the pathological opening of ductus arteriosus. This study aims to investigate the effect of oral acetaminophen on the closure of PDA in preterm neonates. Methods: The present study is a trial without control. Forty-five preterm neonates with a gestational age of <32 weeks were studied. Acetaminophen was orally administered with a dose of 10mg/kg every 6 hours for three days. Closure of ductus arteriosus was considered as the success of treatment. Data were analyzed using SPSS 15. Data were reported as )frequency-percent) and mean ± SD. To evaluate the normal distribution of data, we used a Kolmogorov-Smirnov test. Statistical significance was defined as P<0.05. Results: The study population consisted of 20 male and 25 female infants with the mean gestational age of 28.95 ± 1.66 weeks. Cesarean-born infants and vaginal-born infants consisted 17.8% and 82.2% of the study population, respectively. The proportion of PDA closure after administration of oralacetaminophen was 82.3%. Conclusion: The current study indicates that oral acetaminophen is highly effective in closing PDA. Considering its trivial side effects, it has the potency to be a convenient option for treating this condition.

Abstract Background The management of patent ductus arteriosus in preterm neonates continues to be a topic of discussion and controversy. Prolonged ductal patency in preterm neonates has been associated with significant short and long term morbidities and with increased mortality however, policy of routine treatment of all during neonatal period has failed to show significant improvement in long term outcome. Echocardiography has emerged as a promising modality to screen the newborns at risk of adverse effects of ductal shunting. This helps in identifying PDAs that require treatment to ultimately prevent unnecessary therapy or delay of necessary therapy. There are multitude of studies that have evaluated large number of echocardiographic markers for their predictive utility but only few have included all ductal markers together in a single study. The reported sensitivity (26-100%) and specificity (6-100%) of echocardiographic markers vary over a wide range. Thus, this study was planned with an aim to assess the predictive utility of all available ductal markers and their added advantage of having all over few ones in clinically apparent PDA in preterm VLBW newborns.Methods It was an observational prospective study conducted in tertiary care NICU at Lady Hardinge Medical College, Delhi. Fifty preterm very low birth weight (VLBW) newborns underwent four sequential Echo scans within first 72 hrs; first scan within 12 hours then at 24 hrs ,48 hrs and 72 hrs of age and were monitored clinically for the signs of PDA up to two weeks of life or discharge whichever comes later.Results The Ductal diameter, pulsatile ductal flow pattern, Left pulmonary artery (LPA) velocity, Left atrial to aortic width (La/Ao) ratio, Left atrial volume index (LAVI), Left ventricle to aortic width (Lv/Ao) ratio, E/A ratio and Left ventricular output/superior vena caval (LVO/SVC) flow ratio predicted clinically apparent PDA during first 72 hours of life.Conclusion This study provides insights into the predictive utility of other ductal echo markers along with the routinely measured conventional ones during first 72 hours of life in preterm VLBW newborns.
