Features of isolated maternal fever and triple I* with classification¶ |
Terminology | Features and comments |
Isolated maternal fever ("documented" fever) | Maternal oral temperature ≥39.0°C (102.2°F) on any one occasion is documented fever. If the oral temperature is 38.0°C (100.4°F) to 38.9°C (102.02°F), repeat the measurement in 30 minutes; if the repeat value remains at least 38.0°C (100.4°F), it is documented fever. |
Suspected triple I | Fever without a clear source plus any of the following: - Baseline fetal tachycardia (greater than 160 beats per min for 10 min or longer, excluding accelerations, decelerations, and periods of marked variability)
- Maternal white blood cell count greater than 15,000 per mm3 in the absence of corticosteroids
- Definite purulent fluid from the cervical os
|
Confirmed triple I | All of the above plus objective laboratory findings of infection, such asΔ: - Positive amniotic fluid Gram stain for bacteria, low amniotic fluid glucose (eg, ≤14 mg/dL), high amniotic fluid white cell count in the absence of a bloody tap (eg, >30 cells/mm3), or positive amniotic fluid culture results, or
- Histopathologic evidence of infection or inflammation or both in the placenta, fetal membranes, or the umbilical cord vessels (funisitis)
