Viral illnesses, strain injuries, and lacerations—Dr. Kenneth V. Iserson treated common cases like this several times in a single week, just like many emergency physicians.
The only difference?
He was at the bottom of the world—and the outside temperature was −15°F.
Last month, Dr. Iserson finished up a 6-month tenure as lead physician at McMurdo Station in Antarctica, where he had been since late August.
When asked why he decided to take the post, Dr. Iserson's responded:
“Are you kidding? Who wouldn't want to go if they had the chance?”
“You are challenged to use everything you know and know how to do in medicine,” said Dr. Iserson in an e-mail interview. “The patients are all undifferentiated and supposedly healthy. Nevertheless, we see it all, and then some.”
Dr. Iserson's facilities included a small clinic/hospital with a staff of three physicians, a physician assistant, a physical therapist, a dentist, a medical technologist, an x-ray technician, three nurses, and a flight technician. The facility, which generally gets visits from 135–200 patients per week, has four outpatient beds and three inpatient beds. Dr. Iserson also guided treatment for the South Pole station, which has one physician and one physician assistant, as well as multiple field camps scattered across Antarctica.
Dr. Iserson's salary for his stint at the station was paid by Raytheon Polar Services Co., the main logistical contractor to the U.S. Antarctic Program, a government-funded project operated by the National Science Foundation.
The Sub-Zero ED
Despite the polar environment, Dr. Iserson saw only a few cases of frostbite and one moderate case of hypothermia. “We're all issued extreme-cold–weather gear, and everyone takes its use seriously,” he said.
Instead, the medical condition seen most often is “the crud,” which he defines as a series of viral illnesses that strikes each year. “This year appears to have been worse than most,” he added, “and reflects the large rotating population on station.”
The other common class of medical problem is overuse/sprain-strain, he continued. “Although there is a huge effort to reduce work-related injuries, this is an industrial park in the middle of a very unforgiving environment. Therefore, these injuries happen. That's one reason that we have a year-round physical therapist.”
When he had questions about a difficult case, Dr. Iserson consulted by e-mail with infectious disease specialists, “particularly about our H1N1 concerns and a couple of particular patients,” he said. “Of course, one of our flight surgeons—from the Delaware Air National Guard—is also a Stanford University professor in infectious disease, so that was a big help.”
Although the South Pole station is a full 800 miles away, Dr. Iserson went down there for his work. “The modern facility sits immediately adjacent to the ceremonial South Pole—a nice silver ball with lots of flags—and the actual geographic South Pole,” he said. “They are about 100 feet apart and about 100 yards from the nearest station doorway. At more than 9,000 feet, the physiological altitude can range up to 15,000 feet due to extreme low pressure caused by wind vortices and the Coriolis effect.”
Dr. Iserson was sent to the South Pole station to do gallbladder ultrasound exams required for people spending the winter at that location. “While I didn't know how to do that particular exam before I arrived at McMurdo, spending time with the ACEP ultrasound Web site allowed me to quickly learn and do these exams,” he said.
Because the weather prevented him from leaving for a few days, “I got to see the enormous 'Ice Cube' project to detect neutrinos, the AERO project to measure the cleanliness of the earth's air, and the amazing self-sustaining ice tunnels around the station that carry the water and sewage pipes. The tunnels are a constant −60°F.”
Psychiatry and Surgery
Dr. Iserson said he had a number of patients with panic attacks and depression. “A chronic problem here is sleep disorders.”
One treatment option Dr. Iserson tries to avoid is surgery.
“The most serious 'surgical' cases included a possible appendicitis we treated nonoperatively until we could fly him off the continent,” he recalled. Another challenging surgical case involved a second-degree burn of almost the entire hand. The medical team treated it successfully by incision and drainage of the huge blisters, frequent dressing changes, and immediate full range-of-motion in the bandage. “Not like the books say to do it,” he admitted.
One of the toughest aspects of the job, he said, was deciding when to send a patient off continent. It is often a complex and expensive option. “You must decide what you will have to treat on station, because medical evacuation may not be available due to visibility or weather conditions.”
