Risk factors associated with feed intolerance in very low birthweight infants following initiation of enteral feeds during the first 72 hours of life.
An observational study was carried out in the Kuala Lumpur Maternity Hospital to determine the risk factors associated with feed intolerance in very low birthweight (VLBW, <1501 g) infants given intermittent 3-hourly enteral feeds within 72h after birth. Feed intolerance developed in 85 (64.4 per cent) of 132 infants. Logistic regression analysis showed that the only significant risk factor associated with feed intolerance was the age when the first feed was commenced. For each hour delay in the age of the infants when the first feed was given, the adjusted odds ratios of feed intolerance was 1.03 (95 per cent confidence intervals: 1.01-1.05; p = 0.01). Other factors (modes of delivery, Apgar score at 1 min, sex, ethnicity, history of resuscitation at birth, birthweight, gestation, multiple pregnancy, perinatal asphyxia, types of milk, hypothermia before first feed, hypotension before first feed, respiratory distress syndrome, patent ductus arteriosus, septicaemia, theophylline therapy, indomethacin therapy, ventilatory support, continuous positive airway pressure, umbilical catheterization, and surfactant therapy) were not significantly associated with feed intolerance. Our study suggests that to promote tolerance of enteral feeds in VLBW infants, intermittent orogastric feeds should be commenced as soon as possible during the first 72 h of life.
