A belated thing for me to be thankful for

One of the reasons I started a blog was also to serve as my personal soapbox to get the word out about Congenital Heart Defects - CHD's. I found this on the CHD Blog, and they got it off another heart blog - "Adventures of a Funky Heart". Since is the first time I'm using another post on my blog, I do hope I'm giving proper credit here...:) Hope I don't step on any toes!

I am immensely grateful and thankful for the wonderful, courageous, pioneering doctors and medical staff who came before us, and who had the courage to do what was considered impossible. The following is a small bio of one of them. You also can learn a bit more if you watch the movie "Something the Lord Made". Here's the post:

Vivien Theodore Thomas was born on August 29, 1910 in Lake Providence, Louisiana. After graduating high school in 1929, he planned to attend Tennessee Agricultural and Industrial State Normal School, (now known as Tennessee State University) with hopes of becoming a doctor.

He had been in school two months when the stock market crashed, causing him to lose his part-time carpentry job. Forced to drop out of college, Thomas still found work as a Lab Assistant at Vanderbilt University Medical School, working for surgeon Dr. Alfred Blalock. Although hired to sweep floors and clean out cages, Vivien Thomas impressed Dr. Blalock with his intelligence. Blalock was so impressed that he trained Thomas to be his Surgical Technician.

Thomas began assisting Blalock in the study of shock during surgery. Shock is caused by a sudden drop in blood flow through the body, and can be fatal. Working together, Blalock and Thomas developed ways to prevent shock from occurring during an operation. By World War II most of their theories were in use, saving the lives of countless injured soldiers.

In 1941, Dr. Blalock was hired by Johns Hopkins Hospital in Baltimore, Maryland, to serve as the hospital’s Chief Surgeon and as a Surgical Professor in the Hopkins Medical School. The doctor asked his trusted assistant to go with him, and Thomas agreed. But while Blalock was responsible for training every surgeon in the school, Thomas had to enter the building through the service entrance. He was also listed on the hospital payroll as a handyman.

The two men respected and trusted each other, but were hardly equal. At one time, Blalock was paid ten times more than Thomas. Often the doctor hired Thomas to serve drinks in his home during a social event. And never was Thomas allowed in the Operating Room.

It was at Johns Hopkins that the two men met Dr. Helen Taussig. Taussig had been hired in 1930 to oversee the Cardiac Clinic of the Harriet Lane Home, and quickly grew interested in “Blue-Baby” diseases.

Usually, blood coming into the heart is routed first to the lungs, where it absorbs oxygen. The oxygen rich blood then goes back to the heart, where it is pumped throughout the body. Blue Babies are born with a badly formed heart or blood vessels that cannot provide enough oxygen to the blood. Their skin has a distinctive blueish tinge, especially in the fingertips. At that time Blue Baby diseases were incurable, and almost all of the patients died very young.

Dr. Taussig approached Dr. Blalock with an idea: if a Blue Baby’s heart couldn’t provide oxygen to the blood naturally , then why couldn’t a surgeon re-route the major blood vessels? Taussig’s plan was interesting but extremely dangerous. The operation would have to take place near the heart, and heart surgery was so risky it was almost never recommended. Any accidental damage to the heart would have to be repaired within 4 minutes, or the patient died.

Busy with his teaching duties, Blalock asked Vivien Thomas to work out the details of how such an operation could be done. Thomas began by studying medical textbooks, drawings and diagrams of hearts, and even real hearts taken from dead bodies. Then he operated on dogs, intentionally creating Blue Baby hearts in them. Later he would operate again, repairing the heart and making careful notes of everything he did. It was a slow process, learning exactly what had to be done. Many dogs died, and several of the surgical tools he needed didn’t even exist. Quite often, Thomas would invent them.

X-rays of the patient were another problem. X-ray films provide a good still photograph of the workings of the body. But Taussig preferred to use a fluoroscope. A fluoroscope image is best described as “X-ray TV”– It provided moving images of the interior of the body. If the patient accidentally moved, so did the picture. There was no way to record the fluoroscope image, so the three doctors would have to study their patient’s fluoroscope scans carefully and commit them to memory.

At last they felt they were ready, and Taussig began to search for a proper patient. On November 29, 1944, they operated on a little girl named Eileen. Although fifteen months old, Eileen only weighed nine pounds.

Thomas had planned to be in the observation room, watching the operation. Blalock said no – he felt more comfortable with Thomas close enough to give him advice. In preparation for the operation, Thomas had performed the procedure over 100 times on animals. Blalock had been taught the procedure by Thomas, but had actually done it only once. Breaking all the rules of the time, Thomas entered the operating room and guided Blalock through the operation.

Eileen’s heart never stopped beating and her blood vessels were only as thick as a matchstick. After about 90 minutes, Blalock was finished. Everyone held their breath as he removed the last clamp from a blood vessel. After a long pause, Helen Taussig said “Al, the baby’s lips are a glorious pink color.”

Proven to be a success, Blalock’s team performed nearly 300 operations in less than a year. Surgeons came from around the world to study Blalock’s new surgical procedures, only to learn that Thomas was the expert, not Blalock or Taussig. Still, the operation was known as the “Blalock-Taussig Shunt,” named for the surgeon who performed it and the doctor who suggested it.

Blalock retired in 1964 and died four months later. For six years, Thomas continued to teach but took on no major project – almost as if he were in mourning. But as the 1970’s began, more and more African-Americans were entering the Hopkins Medical School. To them, Vivien Thomas was not just one of their teachers, he became their mentor. And just as he had guided Blalock so many years before, Thomas’ advice and support guided a new generation of doctors through medical school.

Thomas died in 1985, just a few days before his autobiography was published.* Today, Vivien Thomas is almost unknown to the general public. But Dr. Alfred Blalock never forgot him. If someone stood too close to his right shoulder during an operation, Blalock would tell them to back away. “Only Vivien may stand there.”

* Thomas’ autobiography has been reissued with a new title: Partners of the Heart: Vivien Thomas and his work with Alfred Blalock.
