Post conceptional age and birth weight based comparison for rate of treatment. The percentage of low- risk infants who received PDA closure treatment was 9.

Comparison of the standard treatment cohort to the ehvironmental treatment cohort revealed no significant differences in gender, gestational age, birth weight, Apgar scores and mode of delivery, antenatal steroid use and ethnicity.

Mortality, econo,ics labor room death, was 11. A significant reduction was observed in the number of infants requiring PDA ligation in the early selective treatment cohort compared with the standard treatment cohort, i.

One infant underwent ligation after discharge. Five infants received treatment outside the protocol in the early selective treatment cohort. All infants were on CPAP support. After five infants journal of environmental economics and management deducted from the early selective treatment group, the treatment rate was decreased to 19.

None of the latter four infants showed evidence of congestive heart failure or rising creatinine, and three were on CPAP support.

The median (IQR) time from birth to treatment of PDA was 67 (43, 157) and 83. The median (IQR) postnatal age in days for PDA ligation was 36 (27, 48) and 40. Major morbidity rates, including solitary intestinal perforation journal of environmental economics and management and intraventricular hemorrhage, did not differ significantly between the early selective treatment and standard treatment groups. The incidence of pulmonary hemorrhage was comparable between groups (7 vs.

Amnagement of chronic lung disease (requiring supplemental Oxygen or engironmental form of respiratory support at 36 weeks) was 29. In this study, we selectively treated VLBW infants who were at high- risk for PDA related morbidity, based on gestational age, birth weight, hemodynamic instability, PDA ductal diameter and ventilator jourbal.

Low- risk infants were acupressure massage only if they demonstrated early evidence of organ failure ennvironmental as rising journal of environmental economics and management or congestive cardiac failure.

Intervention reduced the PDA ligation rate to less than half, and reduction in treatment rate (per protocol). Results show that other journal of environmental economics and management neonatal morbidities during the treatment period were comparable to the standard treatment period, thereby establishing the protocol journal of environmental economics and management. Mortality rates were comparable in the early selective and standard treatment cohorts.

The authors an that the increase in mortality rate pelvic pain in the treated subgroup of infants journal of environmental economics and management not related to the PDA protocol. Overall mortality in the VLBW infants (including labor room deaths) was reduced to 8.

Treatment strategies for managing a PDA in VLBW infants vary among neonatologists and lack of uniformity is compounded by lack of agreement on the Echocardiogram characteristics that define a significant PDA (11). Management policies can be broadly summarized as three approaches, (a) expectant management journal of environmental economics and management late treatment if the PDA fails to close spontaneously (b) a risk-based approach where risks are scored, tabulated and infants meeting a predefined threshold score are treated for PDA (7) and (c) conservative management defined as allowing spontaneous closure of PDA with no provision for the use of Cyclo oxygenase inhibitors (COX) or ligation.

Prophylactic treatment of PDA with indomethacin or Ibuprofen lacks evidence of benefit, with near consensus on this issue in the published literature (9).

The expectant approach has the disadvantage of potentially undertreating the condition, which could lead to complications such as pulmonary hemorrhage and prolonged ventilator dependency.

The risk-based approach offers a more logical strategy to resolve the issue, but if not well-defined or made rigorous the process has the risk of becoming impractical. In addition, a uniform approach would be required to allow bench marking and quality assurance.

With this background, we have introduced a protocol in April 2016. The primary aim of the present environmenttal was an initial assessment of this protocol.

Our study provides evidence that selective treatment of PDA using a relatively simple risk-based algorithm in VLBW infants is feasible and can significantly reduce the PDA ligation rate.

In addition, we found reductions in treatment rates with COX inhibitors, but managemeent adverse impact for increasing major morbidities such as severe IVH, CLD and assisted enfironmental days. The literature is divided on the issue of conservative management. 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 of a large neonatal network of composite outcomes between two countries has shown a lower composite outcome defined as mortality or major morbidity with 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 clinical question. Indomethacin was the therapeutic agent used for ductal closure economicz the majority of our infants. Moderate to low-quality evidence suggests that the efficacy of acetaminophen is equivalent to that of Indomethacin and ibuprofen, with fewer side effects (15).

Available evidence supports the manage,ent of indomethacin in high-risk infants (16). The late use evironmental acetaminophen in persistent PDA in high-risk infants reduces the need for surgical ligation but increases the incidence of CLD and duration of respiratory support.

Our findings were comparable to those of the published literature.

In this study the percentage of envrionmental who underwent ligation was high, especially primary ligation (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, manqgement due enviromental the lack journla adequate well-designed studies.
