Evidence of failure of organ system other than the gastrointestinal tr
act was reviewed in a series of 46 infants treated for necrotizing ent
erocolitis (NEC) at a regional combined medical and surgical neonatal
unit. Respiratory failure was identified in 42 infants (91%), renal fa
ilure in 39 (85%), cardiovascular failure in 15 (33%) and hepatic fail
ure in 7 (15%). The number of systems involved correlated with both se
verity of disease and outcome. Onset of failure in the above systems w
as closely related to the diagnosis of NEC and 29 cases predated the c
linical onset. We conclude that NEC is part of a syndrome of multisyst
em failure and that this has important implications for the treatment
of NEC.
