A young woman, 22-year-old Leticia Paul, sadly passed away following a severe allergic reaction to a special dye, called a contrast agent, used during a CT scan. This tragic event happened on Wednesday, August 20, at the Alto Vale Regional Hospital in Rio do Sul, Brazil. Reports say that during the scan, Leticia experienced anaphylactic shock. This is a sudden, extreme, and very dangerous allergic reaction that can cause a person's throat to close up, making it hard to breathe, and their blood pressure to drop dangerously low. What Caused Her Allergic Reaction? Reports show that her allergic reaction was to ‘contrasting agents’ used in a CT scan. According to Radiologyinfo, for Patients, doctors use special liquids called contrast agents to make organs and blood vessels stand out in medical scans like CT or MRI. These are not permanent dyes; they're temporary substances that help highlight specific body parts, making it easier for doctors to find and diagnose problems. They can be swallowed, injected, or given rectally and are naturally cleared from the body afterward. What Is Anaphylactic Shock? According to the UK National Health Services, anaphylaxis is a very serious and fast-acting allergic reaction. It's an emergency that happens when your body overreacts to something it's allergic to, like certain foods, medications, or insect stings. This reaction can be so severe that it becomes life-threatening. Following the allergic reaction, Paul was intubated at the hospital. Her aunt, Sandra Paul, confirmed to local news outlets that her niece died less than 24 hours later, on Thursday, August 21. Sandra Paul also shared that her niece had a history of kidney stones and was undergoing a routine checkup at the time of the incident.Also Read: What Does Finn Wolfhard's Journey Highlight About Young Stars Dealing With Mental Health Issues? How To Recognize An Anaphylactic Shock – First Symptoms The signs of anaphylaxis appear very suddenly, usually just minutes after coming into contact with the substance you're allergic to. The symptoms can be different for everyone, but here are the most common things to look out for: Swelling A major sign is swelling, especially in your throat or on your tongue. Breathing Problems Anaphylaxis can make it hard to breathe. You might start breathing very fast, or you could hear a wheezing sound when you breathe. Your throat might feel tight, making it difficult to swallow, and your voice could become hoarse. You might also have a persistent cough. Blood Pressure Drop This is a very dangerous part of the reaction. It can make you feel faint, dizzy, or even cause you to pass out. Your skin might feel cold and clammy, and it can look pale, grey, or even bluish. If you have darker skin, you can often see this change on the palms of your hands or the soles of your feet. Other Reactions That May Also Happen? You might also feel very tired or confused, which is another sign that your body is in distress. It’s also common to get a rash that is swollen, raised, and very itchy. What Are Some Precautions You Should Take For Allergies? If you suspect you're having an anaphylactic reaction, use your adrenaline auto-injector right away, even if your symptoms seem mild. It's also a good idea to wear medical alert jewelry, such as a bracelet, that details your allergy. This can provide crucial information to others in an emergency. Finally, do not store your adrenaline auto-injectors in places that are too hot or too cold, like a refrigerator or in direct sunlight.
