A recent meta-analysis has shown no difference in morbidity or mortality when PDA is either treated with placebo or not treated (12, 13). Comparison vk com v a large neonatal network of composite outcomes between two countries has shown a lower composite outcome defined as mortality vk com v major morbidity vk com v aggressive management. A safe approach is required to address this question, especially in 22- to 26-week infants (14).

The outcomes of large RCTs with no treatment or placebo treatment arms-with no provision for open label treatment, is required to answer this pfizer au question. Indomethacin was the therapeutic agent used for ductal closure in the majority of our vk com v. Moderate to low-quality evidence suggests that the efficacy of acetaminophen is vk com v to that of Indomethacin and ibuprofen, with fewer side effects (15).

Available evidence supports the use of indomethacin in high-risk infants (16). The late use of acetaminophen in persistent PDA vk com v high-risk infants reduces the need for surgical ligation but increases the incidence of CLD and duration of vk com v support. Our findings were comparable to those of the published literature.

In a study involving 4,001 infants in a recent cohort of VLBW infants, 21. In this study the percentage of infants who underwent ligation was high, especially primary vk com v (20). Although available evidence suggests improved short and long term outcomes in VLBW infants with reduced PDA treatment (21), it has not been conclusively proven, primarily due to the lack of adequate well-designed studies. Our criteria defining high- risk infants on the basis of birth weight and gestational age as essential elements is supported by the published literature (21, 23).

This study combines the principle of expectant management in low-risk infants with relatively aggressive management of PDA in high-risk infants. The study used lower post-conceptional age and higher levels of vk com v support to define high-risk infants. The study also defined the criteria for identifying a small group of low-risk infants who benefit from PDA treatment.

As compared to the current study, published studies testing risk-based approaches to identify vk com v benefitting from PDA omnipaque used either Echocardiogram (ECHO) based criteria alone or ECHO features combined with lower levels of respiratory support and higher gestational age to define high-risk infants (21, 24).

The authors vk com v unable to identify other published studies in the English literature that combine principles of relatively aggressive management in high-risk infants with expectant management in low-risk infants, and which incorporate defined criteria for identifying the small number of infants in the low-risk group who require treatment.

Implementation of guidelines employing a conservative approach to PDA management has shown a reduction in treatment rate similar to vk com v observed in the current study (25). Our study has limitations. Compliance is a significant issue in the implementation of any clinical protocol. The study is an observational study-not an RCT, and the treatment in the retrospective standard treatment group is heterogenous and not protocol based.

Authors made a systematic effort to analyze the data from the period to mitigate the impact of the absence of a defined protocol in the standard treatment period. Authors have vk com v the additional data as Supplementary Tables that would aid sample size calculation in a future randomized controlled trial. Vk com v protocol relied on measured ductal vk com v as the sole Echocardiogram feature to vk com v ductal significance in the treatment decision algorithm.

Addition to the protocol of absence or reversal of flow in diastole would likely better vk com v the magnitude of ductal shunt in VLBW infants. The number of infants who received indomethacin prophylaxis was higher (11 vs.

The difference was not statistically significant, although it may have some beneficial impact on the treatment rate outcome of the protocol. Our study provides preliminary evidence that selective treatment of PDA in high risk infants is feasible without altering short term outcomes.

However, the protocol needs to be validated in a large randomized control trial (RCT) with long-term follow up to obtain further evidence. Inclusion or exclusion of 26-week infants in the high- risk group is a vk com v of contention, and inclusion with the provision of subgroup analysis is probably a pragmatic approach in designing a future study. We would consider a RCT in high- risk infants with a no treatment placebo control arm as a radical and ethically questionable approach given the current state of knowledge.

Our study provides preliminary evidence that selective treatment of high- risk VLBW infants with significant Vk com v is efficacious. Such a policy would eliminate unnecessary exposure to COX inhibitors and PDA ligation, without significantly affecting the rate of major morbidities in this vulnerable population.
