Effective management of trauma in pregnancy requires a dual focus on two patients: the mother and the fetus. However, the sources emphasize that the best initial treatment for the fetus is the optimal resuscitation of the mother. To provide effective care, clinicians must navigate significant anatomical and physiological changes that alter injury patterns and responses to shock.

Physiological Adaptations and Hemodynamics Pregnancy induces hypervolemia, with plasma volume increasing steadily until 34 weeks. This allows a healthy pregnant patient to lose 1,200 to 1,500 mL of blood before exhibiting typical signs of hypovolemia, such as tachycardia or hypotension. Consequently, maternal vital signs may appear stable even when the fetus is in distress due to compromised uterine perfusion. The fetal heart rate is a sensitive ind ...
