5 th International Workshop on Neonatology The Future of European Neonatology Cagliari, October 30-31, 2009 Non Steroids Anti-inflammatory Drugs in the treatment of PDA in European Newborns Hercília Guimarães On the behalf of the Collaborative Study
NSAIDs to treat PDA in European Newborns Introduction I PDA is a common cause of morbidity and mortality among VLBW infants. The clinical decision of treating PDA should be carried out on an individual basis, according to the clinical condition of the newborn, its hemodynamic importance and potential risks. Echocardiographic evaluation is necessary to establish the diagnosis and to follow the treatment.
NSAIDs to treat PDA in European Newborns Introduction II Indomethacin and ibuprofen, NSAIDs, used in the treatment of PDA in preterm newborn infants have been shown to produce closure in approximately 85% of patients. The choice for Indomethacin or Ibuprofen should be established after evaluation of the clinical condition, costs and local or regional availability
NSAIDs to treat PDA in European Newborns Aim To know the European reality on NSAIDs in the treatment of PDA in preterm newborns.
NSAIDs to treat PDA in European Newborns Material and Methods A questionnaire to be filled was sent to: Presidents of the 24 European Societies of Neonatology/ Perinatology (UENPS) and 3 representatives NICUs in Europe ( UK, Belgium, Germany)

NSAIDs to treat PDA in European Newborns Results 45 NICUs from 19 countries filled the questionnaire: 1 (2 %) - North 26 (58 %) - South 12 (27 %) - East 6 (13 %) - West
Number of admissions, VLBW infants and PDA / year n=45 Mean SD Median (min – max) Admissions (125–1300) VLBW infants (4–550) PDA (2–150) % PDA/ admissions (0.4–25) % PDA/ VLBW infants (3–100) PDA= patent ductus arteriosus; VLBW infants

Indomethacin and Ibuprofen The perfusion of Indomethacin is done during : 30 minutes in 20 (63%) NICUs 60 minutes in 8 (25%) 20 minutes in one. The number of treatment courses used is : 2 in 20 (45 %) NICUs 3 in 12 (27 %) NICUs more than 3 courses in 2 1 NICU uses 2 courses of Ibuprofen + 1of Indomethacin
Indomethacin and Ibuprofen Prolonged treatment (4-6 days) was mentioned by 20 (45%) NICUs. The selected newborns to prolonged treatment are: failure of 3 treatment courses in 7 (35 %) < 1500g in 6 (30 %) < 1000g in 3 (15 %) all babies in 2 critical conditions in 1 Ibuprofen failure in 1
Indomethacin and Ibuprofen Prophylactic treatment is used in 2 NICUs 11 (25%) treat no hemodynamically significant PDA 43 (98%) treat hemodynamically significant PDA. 1 NICU uses surgical closure as first line treatment.
Indomethacin and Ibuprofen Fluid restriction during NSAIDs treatment in 36 (80%) NICUs the percentage of restriction is 20% in 9 NICUs and 30% in 5. 9 (20%) NICUs stop oral feeding during NSAIDs treatment. Diuretics are used in 22 (49%) NICUs: furosemide in 19 (86%) furosemide and/or spironolactone in 3 (+ NSAIDs)
Indomethacin and Ibuprofen The diagnosis of PDA is confirmed by echocardiography in all NICUs. The echocardiographic criteria of hemodynamically significant PDA are: ductal diameter >1.4mm in 28 (64%) NICUs; left atrial:aortic root >1.3:1 in 31 (70%); retrograde diastolic flow in desc. aorta>30% of anterograde flow in 24 (55%) 15 (34 %) use other criteria. 37(82%) NICUs monitor PDA by echocardiography.
Indomethacin and Ibuprofen Surgical closure of PDA is proposed : after failure of 1, in 2 (5 %), 2, in 20 (45 %), and >3, and 12 (27 %) NICUs after 3 weeks of life in 24 (53 %) before 3 weeks of life in 12 (27 %) in babies < 1000g, in 17 (39%) contra-indications to NSAIDs in 27 (61 %)
Indomethacin and Ibuprofen Pedea R is the iv Ibuprofen solution used Ibuprofen oral solution has a concentration of 20mg/ml.

Indomethacin and Ibuprofen The choices are influenced by economical reasons in 10 (22%) NICUs.
NSAIDs to treat PDA in European Newborns Conclusion Our data show a wide variation among NICUs and countries regarding the use of NSAIDs to treat PDA and no general guidelines are followed. Guidelines or recommendations are necessary to treat PDA in Europe, giving all newborns identical health care opportunities.
