II. Causes
- Uterine Rupture
- Uterine Hyperstimulation
- Placental Abruption
- Umbilical Cord accident
- Uteroplacental Insufficiency
III. Definition: Nonreassuring Fetal Status (preferred term)
- Fetal Heart Tracing suggestive of Hypoxia
IV. Evaluation
- Fetal status
- Confirm findings with alternative monitoring
- Consider fetal scalp electrode
- Response to acoustic or scalp stimulation
- Consider Fetal Scalp pH (pH < 7.20 is abnormal)
- Confirm findings with alternative monitoring
- Maternal status
- Maternal Vital Signs
- Vaginal examination
- Vaginal Bleeding (e.g. Placental Abruption)
- Cervical examination
- Cervical dilation
- Rapid head descent
- Umbilical Cord Prolapse
V. Management: Based on Fetal Monitoring
- NICHD Category 1: Normal
- Reassuring Fetal Heart Tracing
- Fetal Heart Rate 110-160 bpm with moderate variability and no variable or Late Decelerations
- Continue current management
- NICHD Categry 2: Indeterminate
- Non-reassuring Fetal Heart Tracing (lacking category 1 criteria without category 3 criteria)
- See interventions below
- NICHD Category 3: Abnormal
- Ominous Fetal Heart Tracing
- Recurrent variable or Late Decelerations, Fetal Bradycardia or sinusoidal pattern with loss of FHT Variability
- See interventions below
- Expedite delivery

VI. Management: Interventions for Non-reassuring Fetal Heart Tracing
- Maternal position change
- Oxygen 8-10 liters per minute by non-rebreather mask
- Intravenous Fluid Resuscitation
- Suppress labor
- Discontinue Oxytocin
- Consider holding pushing
- Consider Terbutaline SQ 0.25 mg
- Consider Amnioinfusion
- Consider expedited delivery
- Consider Consultation
- Obstetrics
- Neonatology or Pediatrics
