Stage IA characteristics are as follows:

  • Mild, nonspecific systemic signs such as apnea, bradycardia, and temperature instability are present

  • Mild intestinal signs such as increased gastric residuals and mild abdominal distention are present

  • Radiographic findings can be normal or can show some mild nonspecific distention.

Stage IB diagnosis is the same as stage IA, with the addition of grossly bloody stool.
