Background: National and international guidelines (ILCOR, AAP and ER) give recommendations on the resuscitation of VLBW infants, including oxygen administration or positive pressure ventilation (1,2,3). We wanted to find out how consistently neonatologist in German speaking European countries adhered to the recommendations of these guidelines.

We surveyed the current management of very low birth weight infants (VLBW) (birth weight <1500g) at birth in Germany (FRG), Switzerland (CH) and Austria (A).

Methods: In a questionnaire based study, we obtained data on delivery room equipment and management of VLBW from all national neonatal units caring for VLBW infants.

Results: In total, 249 units were approached (FRG n=193, CH n=42, A n=14). The recall rate was 77.1% (n=192). Complete answers were obtained from 188 (75%) units. 48 (26%) were university and affiliated units, 140 (74%) non-university units. Management guidelines of VLBW existed in 94% of units. Perinatal management: Most VLBW were cared for in the delivery unit (55%). Placental transfusion (late clamping) was practiced by 43%. Thermoregulation: plastic foil 62%, head cover/woollen hats 81%. Airway management: self inflating bags were used in 92%, bags with mounted manometer in 37%, bags with fixed PEEP-Valves in 71%, T-piece resuscitators (e.g. Neopuff®) in 40%, CPAP with sustained inflations >5s 25%, Starting-CPAP 4-5 cmH2O 76%, humidified gas 42%, use of pulse oximetry 99%. Regarding the use of oxygen in the delivery unit, 80% of clinics used oxygen blenders to titrate the FiO2. 30% of clinics would start with a FiO2 of 0.21, approx. 10% would use an FiO2 of 1.0. For all investigated parameters, no significant differences were found between university and non-university units or between countries.

Discussion: We document the existence of very heterogeneous protocols for the management of VLBW infants, in particular with respect to airway management. Our results are in keeping with those published by O´Donnell (4) for Australia and New Zealand, and by Iriondo (5) and colleagues from Spain or Kiefer (6) and coworkers from the USA. We believe this heterogeneity reflects the need for the generation and rapid distribution of sound evidence from clinical trials.

Conclusion: Data from other European countries should be obtained in order to survey the regional practices of neonatal management and compare these with the current recommendations and the best available evidence from clinical research in order to formulate up to date evidence based recommendations for the care of VLBW infants.
