Sir,
We read with great interest the paper by de Klerk et al.1 on the
Columbia approach and respiratory outcome in very low birth weight
infants. Since 1986 the Brindisi Neonatal Intensive Care Unit (NICU) has
been using a minimal handling approach (nasal CPAP and/or nasal IPPV) for
respiratory assistance in very low birth weight infants. From July 1, 1990
to July 1, 2001 a total of 57 extremely low birth weight (ELBW) infants
admitted to the NICU (M:19, F:38; mean birth weight: 846!123 g; mean
gestational age: 26.9±2.5 weeks) survived for at least 36 weeks’
postconceptional age. Oxygen-dependence at 28 days of postnatal age (BPD-
28d) was present in 22 infants (38.6%) while only 1 infant (1.7% of the
whole ELBW population) still needed ventilatory support and supplemental
oxygen at 36 weeks’ postconceptional age (BPD-36wk). The observed
prevalence of BPD-36wk in ELBW infants is significantly lower than it
should be expected (30%) from the literature2-3 (p=0.000041, Fisher's
exact test, two-tailed probability). This observation seems to confirm
that a less invasive approach to mechanical ventilation not only can, but
has to be attempted although sufficiently large, randomized controlled
trials are needed to verify our clinical experience. A possible
explanation for the reduced incidence of BPD using a minimal approach may
reside in the reduced exposure to phthalates released from endotracheal
tubes.4
