Trauma in pregnancy
Background
Viable = >20-24wk (~fundus above umbilicus)
nl FHR = 120-160 beats/min
For maternal vitals see OB/GYN: Vitals
Concern for trauma and abruption
Diagnosis (Abruption)
Symptoms
1. Vag bleed
2. Cramps/contractions
3. Uterine tenderness
4. Hypovolemia
5. Abnl fetal HR
US only 50% acurate
Treatment & Disposition
A. Nonviable fetus (<20-24wks)
-Standard treatment for trauma
-Consider RhoGAM
B. Viable fetus (>20-24wks)
-Consider RhoGAM
-Monitor (fetal) all for 4-6hrs -->
-Extend Monitoring to 24hrs, if risk factor or abnormal 6hr monitoring
Risk Factors (ATLS)
1. Maternal heart rate > 100
2. Injury Severity Score > 9
3. Evidence of placental abruption
4. Fetal heart rate > 160 or <120
5. Ejection during a motor vehicle crash
6. Motorcycle or pedestrian collisions
Abnormal Monitoring
1. >3 contractions/hr
2. Persistant uterine TTP
3. Worisome strip
4. Vag bleed
5. PROM
6. Serious maternal injury
Partial abrution w/ stable mom/fetus and <32wk may have expectant care (with easy access to emergent C-section)
Abrupion = risk DIC
