In medicine, I think its less common that we are honestly "saving lives". More commonly, we are treating flare-ups of common conditions, such as congestive heart failure exacerbations or COPD (ie chronic obstructive pulmonary disease, aka emphysema or bronchitis) exacerbations. However, there is a case that I treated recently, in which we saved a 21 year old's life.
I just finished the ICU (intensive care unit), a grueling and challenging month where you are treating the sickest of the sick. One of UNC's functions is as a "tertiary referral center", a place where other hospitals send their patients if they need more advanced care. This also applies to ICU patients. If other hospitals receive ICU patients who are too sick...they come to UNC, and we take care of them.
I had a 21 year old patient, who I'll call John Doe, referred to me from an outside hospital. He was found outside unconscious, and an ambulance was called. When he reached the outside hospital, he body temp was 88'F, and his toxicology screen showed opiates, benzodiazepines (like valium), and cocaine. He wasn't breathing well, so he was intubated and attached to a ventilator. Then, he was sent to us.
When he arrived, he was still cold, but in a matter of hours he began to have fevers, and he became exceedingly difficult to ventilate and keep his oxygen levels up. His lungs began to show a dense pneumonia (lung infection), and also began to show signs of diffuse injury, something we call ARDS (acute respiratory distress syndrome). ARDS can occur when there is any sort of severe insult to the body. He was at the tenuous balance, where we needed to give him as much ventilator support as we could, but not give him too much support which would injure his fragile lungs further. His kidneys had been injured. We placed invasive lines in many parts of his body - there was a tube in his lungs to help him breath, a tube in his stomach to feed him; a large central venous line in his neck to give him fluids and antibiotics; an arterial line in his wrist to closely monitor his blood pressure and take samples of arterial blood to make sure he had enough oxygen; a tube in his bladder to drain his urine; a tube in his rectum to drain his feces. We didn't know what kind of damage to his body the hypothermia caused - we hoped he didn't suffer any brain damage, or that the cold temperatures didn't hurt his organs. And just as dangerous, rewarming him can also cause "rewarming syndrome" which could hurt his organs.
And in addition, no one knew who this person was. We had no name, no ID, no family. He was found by strangers and an ambulance was called, and then was transferred to us.
I was his primary doctor. But we had an ICU team. Other residents and interns took care of him when I wasn't there. The ICU fellows and attendings provided guidance. The nurses carried out the orders, and looked after him very closely.
And then his family showed up, and we found out about this person's life. Had much of an antisocial life, misbehavior, frequently caught up in drugs, stole from his family. All too sad in a 21 year old kid, that he has been slowly ruining his life and killing himself, and now he's here attached to tubes in our ICU.
But he started turning around. Slowly made improvement. We were slowly able to wean the ventilator settings, and his ARDS and pneumonia were beginning to improve. He exhibited signs of drug and alcohol withdrawal, and required high doses of sedatives, but we began scaling back. And after 8 days, we were able to extubate (remove him from the ventilator) him, and he was breathing on his own. He was able to talk to us, and could move all his limbs. He was still intermittently delirious, but had survived the most horrible part of his illness, when he was in total respiratory failure. Now that he did not require a ventilator, and his vital signs remained stable, and no longer in withdrawal, we released him from the ICU to be taken care of by a floor team. I imagined he would be in the hospital another week, recovering and regaining strength and hopefully normal function. We consulted our psychiatry service, to address his underlying drug habits and probable mental illness, hoping they could share some insight with him.
2 days later, I got a phone call from one of my fellow residents. He told me that Mr. Doe was about to be discharged home, and that he would like to come up to the ICU to thank us. To
walk to the ICU! And he did. This 21 year old guy walked up to us, and said "Thank you for saving my life." Gave me a handshake, then a hug. He wanted to see the room where he spent the past 8 days near the brink of death. He wanted to know how sick he was. And then he told us that he was going to change his ways. No more drugs, and turning his life around. Hugged me again, and then walked out of the ICU, and later that day walked out of the hospital and, hopefully, to a new life.
That was one of the best moments of my life as a doctor.
