Discharge outcomes of extremely low birth weight infants with spontaneous intestinal perforations

Abstract

Objective: To examine discharge outcomes of extremely low birth weight infants (ELBW) with spontaneous intestinal perforation (SIP).

Study design: A single-center retrospective cohort study of all ELBW infants admitted to the University of Virginia neonatal intensive care unit between July 1996 and June 2004.

Results: We found 35 patients with SIP (incidence 8.4%). The median gestational age was 25 weeks, median birth weight was 722 g, and 71% of the infants were male. Most infants (n=28) with SIP were diagnosed secondary to pneumoperitoneum; however, one-third (7) of infants<25 weeks had occult presentations without pneumoperitoneum. When controlled for gestational age, gender, multiple gestation, indomethacin, and glucocorticoid exposure, infants with SIP have a higher risk of PVL and death than infants without perforation.

Summary: Periventricular leukomalacia and death are significantly associated with SIP in ELBW after adjusting for gestational age, multiple gestation, indomethacin, and glucocorticoid exposure.
