Airway
Prepare for potentially difficult airway
Increased soft tissue edema, breast enlargement, weight gain
Pregnant women at increased risk of aspiration due to delayed gastric emptying
Failed intubations 8 times more likely in pregnant trauma patients

Breathing
Increased basal O2 requirement
Fetus is highly sensitive to maternal hypoxia
Keep maternal SpO2 >95%
Some recommend placement of thoracostomy tube 1-2 intercostal spaces higher than usual, when indicated

Circulation
Fluid and blood product resuscitation should proceed according to ATLS
Placenta is highly responsive to vasopressors and can result in decreased placental perfusion
Compression of IVC by gravid uterus can decreased CO by 30%
If must be kept supine, allow patient to lay in left lateral position
May also manually displace uterus to the left if patient must be kept on backboard
Fetal risks from defibrillation of mother are small
