The first stool, meconium, is usually passed by 98.5% of term infants, 100% of postterm infants, and 76% of premature infants (majority are >32 weeks) in the first 24 hours of life. The majority of premature infants have delayed passage (37% in 24 hours, 32% beyond 48 hours, and 99% by 9 days in 1 study) (Table 72–1). Delayed passage of meconium was found to be in 81% of very low birthweight (VLBW) infants. Males were found to pass stool later than females. Delayed passage of meconium can be a predisposing factor for bowel perforation. The triad of failure to pass meconium, vomiting, and abdominal distention, is a sign that the infant may have intestinal obstruction.
