What is the primary complication that can occur during pregnancy?

The primary complication that can occur during pregnancy is post-partum haemorrhage. This condition refers to excessive bleeding after childbirth, which can pose significant health risks to the mother. Post-partum haemorrhage is categorized as a major obstetric emergency, and various factors can contribute to its occurrence, including uterine atony (failure of the uterus to contract effectively after delivery), retained placenta, or lacerations. Understanding this complication is crucial for emergency medical technicians, as prompt recognition and intervention can save lives.

While dehydration, high blood pressure, and allergies can also affect pregnant women, they do not have the same immediate and severe implications for maternal health as post-partum haemorrhage. Dehydration can lead to various issues but is generally manageable; high blood pressure—while concerning—may be monitored and treated with medication during pregnancy; and allergies can cause discomfort, but they are not typically classified as direct complications of pregnancy. Understanding the context of post-partum haemorrhage highlights the critical need for monitoring and readiness to address this serious condition in post-natal care.
