An aortic aneurysm is a serious condition in which the walls of the aorta are weakened, causing the blood traveling through the aorta to bulge out. Blood may also enter the interlayer of the blood vessel, resulting in a balloon-like structure developing on the aorta. In this article, we will explore the risk factors, pathophysiology, signs, and symptoms, as well as the treatment options that paramedics may implement when encountering a patient suffering from an aortic aneurysm.
To develop an in-depth understanding of aortic aneurysms, it is necessary to first investigate the risk factors that can result in patients experiencing the disease. Some of the non-modifiable risk factors include being male and/or older, as well as having a positive family history of cardiovascular conditions. On the other hand, modifiable risk factors that can be altered to decrease the risk of developing an aortic aneurysm include obesity, smoking, high blood pressure, drug abuse, and hypercholesterolemia. Hence, aortic aneurysms are a serious health condition with several risk factors that cannot be changed. However, if lifestyle changes are not made promptly, the risk of suffering from an aortic aneurysm can significantly increase.
The pathophysiology of aortic aneurysms involves the weakening and dilation of the aorta. Understanding the underlying pathophysiology is important in diagnosing and treating patients presenting with symptoms of an aortic aneurysm. An aortic aneurysm occurs in the aorta when its walls become weak over time. This can result from many different factors, often from multiple risk factors rather than a single one. For example, high blood pressure can lead to an aortic aneurysm due to the continuous high pressure on the walls, causing them to weaken. Additionally, smoking is another factor that increases a patient's risk of developing an aortic aneurysm. The harmful chemicals in smoke cause oxidative stress and inflammation, which constrict blood vessels and raise blood pressure. If the walls of the aorta become too weak, a bulge, or an aneurysm, will form. If the aneurysm becomes too large, it may rupture, causing another condition known as aortic dissection, which is extremely life-threatening and requires immediate surgical intervention.
For a patient to receive the best care possible, paramedics need to understand the process of treating those suffering from a suspected aortic aneurysm. Assessing a patient's vital signs will be the first step in providing a preliminary diagnosis. Typical vital signs of a patient with an aortic aneurysm include high blood pressure, a rapid heart rate, rapid breathing, low oxygen saturation, and, in some cases, a high temperature. The signs and symptoms that cannot be seen through vital signs may include, but are not limited to, weakness, numbness in the legs, dizziness, pain anywhere around the torso, and a pulsating feeling in the abdomen. The primary goal once a paramedic suspects an aortic aneurysm in their patient is to transport them to the hospital. On the way, things that can be done to treat the patient include administering oxygen to raise saturation levels and, if the patient is experiencing pain, administering pain medication such as morphine or fentanyl, depending on the intensity of the pain. It is appropriate to pre-notify the hospital while en route, to ensure that the right staff is available and ready to treat the patient as efficiently and smoothly as possible. While in transit, it is important to continuously monitor the patient's vital signs and communicate and support the patient by constantly reassuring them and answering any questions they may have about their condition and its potential treatment.
In conclusion, an aortic aneurysm is a serious condition that requires prompt and proper medical attention. Understanding the underlying pathophysiology and risk factors that contribute to the patient's condition is crucial knowledge that paramedics must have. A paramedic plays a critical role in the early identification of aortic conditions. They must be able to recognize the signs and symptoms early to take appropriate and professional care during transport to keep the patient stable and calm. Overall, an aortic aneurysm is a complex condition that requires a coordinated and comprehensive approach from healthcare professionals, including paramedics.
