Recently, we told you a story about how an 81-year-old healthy food lover exaggerates eating healthy food so that he almost lost his kidneys. According to statistics, this message has interested many of our readers – would you like something similar? Fortunately, there are many similar medical stories, and one of them has recently happened in the state of Rhode Island. A 25-year-old girl came to the local hospital with complaints of weakness, respiratory problems and a bluish skin tone. During the test, it turned out that her blood had turned a dark blue color.

The cause of blue blood is lack of oxygen

A girl named Otis Warren picked up the girl's examination. Luckily he had a lot of experience and had already seen patients with blue blood. The doctor suspected that the cause of the girl's skin, nails, and blood blue color was hypoxia and decided to measure the oxygen saturation of her blood. His flair has not disappointed him – while the oxygen saturation of the blood in a healthy person is 97-100%, it was in the patient 67%.

Causes of the blue blood

Dr. Warren diagnosed methemoglobinemia in the girl. The reason for this rare disease is a change in the iron form – this trace element no longer supplies the tissue with oxygen, leading to oxygen deficiency. Based on his medical experience, the doctor recalled that the cause of this disease may be the excessive use of certain medications such as painkillers and antibiotics.

And in this case he has not lost. It turned out to be very painful on the eve of the girl's toothache and she took a large dose of painkillers containing the local anesthetic benzocaine at bedtime. It was he who caused the lack of oxygen, and one night the patient's oxygen-rich bright red blood turned blue.

The effects of oxygen deficiency

If the girl did not come to the hospital in time, the consequences could be extremely sad. The fact is that a person who is deficient in oxygen may suffer irreparable damage to the brain whose end result is death. Fortunately, an experienced doctor knew what to do and injected a girl with a substance called methylene blue. He restored the work of an important blood element of hemoglobin, which can capture oxygen and deliver it to the organs. After the girl spent the night at the hospital, she began to feel better and was released home.

This story can be considered as a great reminder that medicines should be handled with extreme caution. It should always be remembered that even popular antibiotics, which are often prescribed by treating physicians, can pose a threat to human health. For example, do you know about the dangers of oxolinic acid that are usually prescribed for urinary tract infections? Recently, scientists have discovered that many people develop cardiovascular disease because of the use of this antibiotic. What exactly happens to her body can be found in our material.
