The Butterfly Ultrasound in Global Health

The black appearing object on the far left is a vein which is not compressible and therefore indicates there is presence of a clot. 

The most fun I had on this trip was being able to introduce the Butterfly Ultrasound to the trainees. For those of you who have been following along on my Global Health journey you may have picked up on the recent excitement over a handheld ultrasound probe that plugs in to your phone. This tech is so incredible for so many reasons--it has an incredible price point of $2000 USD versus the larger machines which can be up to $20-40K!! The image quality is great and the portability makes it easy to take to the most rural of places! I have now used this device in Rural Bangladesh at the Rohingya Refugee camps, in Nepal, in Ethiopia and will go on to use this in a project with Bridge to Health in Kenya and Uganda! In the image above we diagnosed a blood clot in the leg of a patient with cervical cancer. In the images below there was a patient who was found to have a lung abscess and I wanted to show the trainees what this may look like on ultrasound. ( All photos taken with permission ) We spent the rest of the day asking several patients if they would allow us to perform simple ultrasound to identify normal and abnormal pathology. While the training session itself was limited to the week that I was present we really focused on some basic concepts and luckily the physician who is mainly in charge of the Medical ICU at Ayder is well trained in ultrasound and so with a local expert there is even more of an incentive for trainees to practice and continue to identify important pathology that may aide in early intervention and better patient outcomes.

Early Recognition is life-saving

Today’s lesson is in “early recognition”. I have probably said this over a million times in my short career thus far but I truly think that early recognition and early action are the pieces missing in resource-limited settings. In resource limited areas it is difficult to decide when that early intervention should occur. Frankly, ICU medicine as we know it in the US is a very resource intensive and costly intervention--it has to be redefined in resource-limited countries. I feel very strongly about the power of education and that is not just at the level of health care providers but community level education.  I am referring to going out in the community and talking about the signs/symptoms that should bring people into the hospital, it is far too often that we see the end result of a disease process, when it is too late to act. It is even more important that this early recognition occurs especially when a patient is IN hospital. While on rounds this morning we discussed the new admission, she is a patient who came in with nausea and vomiting, with a history of prior abdominal surgeries. A tube was placed in to her stomach to help decompress her stomach, an X-ray was pretty convincing for bowel obstruction. Over the next 12 hours she started having abdominal pain and there was a concern that her obstruction was worsening so she was taken to the operating room. There she notably had a perforated intestine and had low blood pressures during the procedure. She was taken to the Post op area and for three days continued to have low blood pressures. By the time she came to the medical ICU we were seeing blood pressures of 66/30 (as seen in the picture). I will tell you--when we see this in a medical ICU in a resource-rich country the nurses are already grabbing the pressor medication to help support the blood pressure so that vital organs can be perfused. In many resource limited settings such as this one there may be only one medication available, usually it's Dopamine which is a medication we do not reach for anymore. If the patient requires an additional medication to support his/her blood pressure the patient's family will need to go purchase this medication from the pharmacy and then return with it. Time is crucial in this setting--the longer the patient's blood pressure remains this low the more injury there is to the kidneys, to the brain, to the heart, to all of the vital organs. Unfortunately this patient's family could not afford the appropriate medications and this patient despite everything we COULD do within our capabilities, did not survive. Because of the limitations of the hospital system, of space, the availability of a ventilator--this patient was not able to receive timely interventions. 

This is the devastating reality of what medicine looks like in these parts of the world. 

A triumph for our trainees but a tragedy for the patient

It is difficult sometimes in medicine to temper the interest and maybe even excitement over seeing something abnormal, and reminding ourselves that there is a patient attached to that rare or interesting finding. In teaching at the bedside it is important to remind our trainees that we must respect the true teacher in the room--the patient. Today’s focus is a patient who I am so sad about. He is a 21 year old male who came to Ayder with shortness of breath, he was found to have a significant amount of fluid around his heart and luckily when he came the CT scanner was working so he was able to obtain a scan which showed a large mass sitting inside of his chest. The location of this mass was worrisome for several things including lymphoma. He was evaluated for several different types of infections, fungal and TB especially. Tuberculosis (TB) can really present as anything. After all that was completed he was started on steroids under the presumed diagnosis of Lymphoma. Biopsies were taken, the fluid was drained, he remains on a ventilator because the mass is so big that it is compressing his trachea. Given that he has no indication for sedation, he is getting only intermittent doses of thiopental as needed(a medication we really do not use in the US but is cheap and available here)—this is such a stark contrast to our patients back home who generally end up requiring some level of sedation even continuous infusions to keep them calm and comfortable on the ventilator—I imagine its because we have a lower threshold to start these medications and of course they are more readily available. Back to the patient—he was biopsied and we await the results however given the concern for progression it was decided that he empirically be started on chemotherapy. We shall see how he does—I hope for the best for him, he has his entire life ahead of him, he is awake and interactive and even jokes around with us. Human beings and their capacity for resilience is truly something to behold. The depths of pain people can go through and still remain positive is awe-inspiring to me.

Cow Horn Injury--wait what's that?!

A depiction by Sir Charles Bell of a soldier with Tetanus (from 1890)

There was a time that being in a new environment, not knowing where anything was, or not having any cell service nor maybe even wifi, was terrifying and anxiety provoking. This career in global health has helped me to release that fear somewhat; don’t get me wrong it is still intimidating and always a humbling experience but that initial fear of the unknown has started to melt away or rather transform into excitement and anticipation of what these new experiences will bring, for instance, my first experience with Generalized Tetanus. 

On my first day at Ayder University Hospital in Mek’elle I rounded in the ICU and saw my first case of generalized tetanus. The patient had a testicular injury via cow horn—meaning he was essentially head-butted by a cow. I listened on rounds as this was presented and quietly asked the student next to me what “cow horn” was…she looked at me puzzled, and answered, “You know, like a cow, ‘moo’”. Between the laughter and embarrassment I remembered the rural scene on the drive into the city and had to remind myself “you are no longer in Philadelphia”.  After that moment passed my next question was whether or not the tetanus vaccine was widely available, while the answer is yes, it seems that actual compliance in obtaining it is the difficult part especially in rural parts of Ethiopia. Men are more inclined to get tetanus than women because of the fact that most women of age have had children and it is a part of the antenatal care received. Tetanus can cause painful spasms from such minimal stimulation, the patient requires the mechanical ventilator and frequent doses of sedation. If he is to recover it could take up to 4 weeks of time! 

My Return to Ethiopia (delayed posts)

This year I was asked to bring some critical care lectures and ultrasound training to Mek’elle, Ethiopia. If you recall, last year I had the pleasure of working at Black Lion Hospital in Addis Ababa, the capital of Ethiopia. It was a wonderful experience that was provided by the East African Training Initiative—a group that initiated out of Columbia University and over the years has partnered with several other academic institutions, to bring a Pulmonary Fellowship to Black Lion Hospital. Now years after its inception the program has trained and dispersed several well-trained Pulmonologists who are now all over the country. Mek’elle is a beautiful city about an hour plane ride away from Addis. I was greeted by greenery and beautiful rolling hills as we descended on to Mek’elle. The drive to the hotel displayed the rural areas outside of Mek’elle and within 20 minutes we arrived in the city center. After 24 hours of travel I am exhausted but excited to see what Ayder University Hospital has to teach me!
