Getting the DNR--ethics and end of life decisions

During an internal medicine residency, newly hatched doctors are responsible for some of the sickest patients in their teaching hospitals. This is because those patients often don't have private doctors to attend them and are poor and sometimes self abusive, with the complex problems that go with smoking, drug and alcohol abuse and lack of regular medical care. These patients often present with their diseases late in game, when much must be done quickly. There is little or no time to discuss end of life issues and so the assumption is made that these folks want "everything done" which includes machines and potions to support organs and bodily functions as they cease to work right. A scenario might look like this: 48 year old heroin abuser comes in with fever of 104 and symptoms of a stroke. He is admitted to the intensive care unit with low blood pressure, becomes gradually delirious and his heart rate increases, he is sedated for trying to crawl out of bed and run off, he becomes lethargic and is unable to breathe for himself, a central line is inserted and he is intubated and put on a ventilator, his blood pressure is supported with pressors and fluids, his oxygen level cannot be supported despite high ventilator settings. His kidneys cease to work and his heart goes into a rhythm that produces no blood pressure at all, he receives CPR with chest compressions, he is resuscitated, but barely alive, unable to communicate, obviously brain damaged beyond repair, placed on dialysis, eventually succumbs to overwhelming infection. We call this a "flail."  It is horrifying and time consuming and ultimately a colossal waste of human and monetary resources. Repeated experiences of this type sour most of us on the idea of being resuscitated, so many doctors consider themselves "DNR (do not resuscitate)." We don't want to be resuscitated ever, no matter what. There are some things that are worse than death.

Some resuscitations go well, though. A patient arrives in the emergency department with chest pain, develops an arrhythmia, has chest compressions briefly and electrical cardioversion and is conscious within minutes or hours. Some people briefly can't support their own needs for respiration and require a few days of ventilation before being able to breathe adequately. Although they are weak and puny for awhile, they go home and live to tell the story, go back to work, raise families, climb mountains. These successes usually happen to people who were vital before they became really sick, the younger folks, without multiple or terminal illnesses to begin with.

When someone is admitted to the hospital, the physician responsible for their care (which is more and more often the hospitalist) determines, if possible what their wishes would be regarding life support should their breathing or heart stop. These discussions are very difficult if the patient has not thought about resuscitation and has not talked with a physician who knows them about options. Often patients have reasonable hesitance to make potentially life determining decisions with a doctor who they don't know and who doesn't have time to talk with them about the implications of these decisions. In our heads we have a pretty good idea of which patients would do well should they require cardiopulmonary resuscitation, and we really want people whose chances of recovery are lousy to tell us that they are DNR. A DNR decision means that will not flail them. We will not get into a situation in which failure is likely. Should this patient become so sick that medicines, hydration and appropriate surgical procedures cannot save them, we will transition to a strategy that makes death peaceful and painless. 

We rarely succeed in communicating this to patients and many who will not benefit from cardiopulmonary resuscitation say "Oh yes, doctor, I want everything done." Some say this because their experiences are different from ours, they have seen doctor shows in which resuscitation was successful, they think that withholding resuscitation means getting substandard care, and sometimes they think that we just want to spare ourselves the trouble of saving them. And some of these concerns are valid. A patient who is "DNR" may not be watched as closely or treated as quickly if they decompensate. Some people with horrible prognoses do get better after being resuscitated, though this is pretty uncommon and usually involves a pretty significant decrement in quality of life.

Even though it is hard to establish trust with patients or their families in the context of being a hospitalist, I think it is one of the most important discussions to do right. It is everso tricky, though. Even asking the question can make a patient frightened or hostile. They wonder if we are asking this question because we secretly think they are going to die soon. They feel that the subject is too private to broach with a near stranger. They have never thought about it and don't want to start now. They think that if they make a decision not to be resuscitated that their family members will think that they don't love them. But sometimes patients have been waiting, oh so patiently, for someone to bring up the subject and be willing to take enough time to answer the questions that they have been afraid to ask. I find that a discussion of resuscitation is best started after I learn about who a patient is and what they have done for a living and what they spend their time doing at home. What were they good at when they worked? Do they have kids or grandkids? Where do they live, do they travel, do art, take care of other people, have pets? It is hard or impossible to help a person navigate the end of life if I don't know them. 

Even though I am a bit biased against intensive and technological medical care, I love actually doing it. The tools of this trade are really clever and the immediacy of the practice is inspiring and brings people together. I have seen beautiful and compassionate intensive care, which makes patients and families feel valued. Nevertheless, there are always the unintentional and casual cruelties of disturbed sleep, needles, boredom, prickly heat, bowel indignities, physical pain and nausea. Death following chest compressions and electrical cardioversion is not peaceful. When I sit with a person and hear that, no, they don't want intensive care or cardiopulmonary resuscitation should their heart or lungs cease to work, and it is clear that resuscitation is not in their best interest, my heart feels lighter. I can focus more on what the patient values rather than what procedures are most likely to keep them alive for the longest time.

How to make your own ultrasound gel (which is also sterile and edible and environmentally friendly) **UPDATED--NEW RECIPE**

I have been doing lots of bedside ultrasound lately and realized how useful it would be in areas far off the beaten track like Haiti, for instance. With a bedside ultrasound (mine fits in my pocket) I could diagnose heart disease, kidney and gallbladder problems, various cancers as well as lung and intestinal diseases. Then I realized that I would have to take a whole bunch of ultrasound gel with me which would mean that I would have to check luggage, which is a real pain when traveling light to a place where luggage disappears. I heard that you can use water, or spit, in a pinch, or even lotion, though oil based coupling media apparently break down the surface of the transducer. Or, of course, you can just use ultrasound gel. Ultrasound requires an aqueous interface between the transducer and the skin or else all you see is black. Ultrasound gel is a clear goo, looks like hair gel or aloe vera, and is made by several companies out of various combinations of propylene glycol, glyce

Ivermectin for Covid--Does it work? We don't know.

  Lately there has been quite a heated controversy about whether to use ivermectin for Covid-19.  The FDA , a US federal agency responsible for providing unbiased information to protect people from harmful drugs, foods, even tobacco products, has said that there is not good evidence of ivermectin's safety and effectiveness in treating Covid 19, and that just about sums up what we truly know about ivermectin in the context of Covid. The CDC, Centers for Disease Control, a branch of the department of Health and Human Services, tasked with preventing and treating disease and injury, also recently warned  people not to use ivermectin to treat Covid outside of actual clinical trials. Certain highly qualified physicians, including ones who practice critical care medicine and manage many patients with severe Covid infections in the intensive care unit vocally support the use of ivermectin to treat Covid and have published dosing schedules and reviews of the literature supporting it for tr

Old Fangak, South Sudan--Bedside Ultrasound and other stuff

I just got back from a couple of weeks in Old Fangak, a community of people living by the Zaraf River in South Sudan. It's normally a small community, with an open market and people who live by raising cows, trading on the river, fishing and gardening. Now there are tens of thousands of people there, still displaced from their homes by the civil war which has gone on intermittently for decades. There are even more people now than there were last year. There is a hospital in Old Fangak, which is run by Jill Seaman, one of the founders of Sudan Medical relief and a fierce advocate for treatment of various horrible and neglected tropical diseases, along with some very skilled and committed local clinical officers and nurses and a contingent of doctors, nurses and support staff from Medecins Sans Frontieres (Doctors Without Borders, also known as MSF) who have been helping out for a little over a year. The hospital attempts to do a lot with a little, and treats all who present ther
