Postpartal infection is most commonly associated with trauma and blood loss due to the physiological changes and potential complications that occur during the delivery process. When a woman experiences significant blood loss during or following childbirth, it can compromise her immune system and ability to recover, making her more susceptible to infections. Additionally, trauma during delivery, such as lacerations or surgical incisions from a cesarean section, can provide an entry point for bacteria, further increasing the risk of infection.

Considering this context, trauma and blood loss synergistically contribute to the risk of infections like endometritis and surgical site infections post-delivery. Maintaining hemodynamic stability and minimizing trauma during labor and delivery can help reduce this risk.
