Internship Rotation 12: Trauma, 2 Weeks

This has been my favorite rotation so far. I enjoyed the variety in work, the complexity of the injuries and the story behind each patient. The two weeks flew by! The Shock Trauma Center is part of the University of Maryland Medical Center but is technically a free-standing hospital despite the connection in hallways; it is the primary trauma care facility for Maryland and is a level one trauma center so we were exposed to the most severely injured and sickest patients from the state. This trauma center is also well-known for being the first in the world to treat shock. We spent our weeks working with gunshot wounds, stabbings, traumatic brain injuries, motor vehicle crashes, motorcycle crashes, multiple types of brain bleeds, struck pedestrians, falls, and necrotizing fasciitis (part of the soft tissue segment of the trauma department). We then had to deal with the situations that come with these injuries such as colostomies, paralysis, chronic intubation/trach, long-term feeding tube access, long-term parenteral nutrition, uncontrolled blood glucose values, altered mental status, sedation, lean body mass breakdown, amputations and more. Some stories from the week:

• One of the patients was brought in after a drive-by shooting, but happened to have a warrant out for their arrest so they became a patient and a prisoner in one day. When the family came for a visit and got turned away by the police officer standing guard, a verbal fight ensued where one of the relatives almost got arrested for refusing to obey the officer.
• I had multiple patients die during this rotation but somehow I had more exposure to the families this time so it was more difficult, especially since most of the patients had been healthy prior to their traumatic injury and their death occurred at a completely unexpected time.
• We got to work with quite a few "interesting" patients where mental status declines led to some odd behaviors involving nudity, yelling, and cussing. One patient that we discussed with the med team was in with suicidal and homicidal tendencies. The homicidal tendencies were directed at medical professionals - so glad that I didn't work with them.
• We frequently had patients who were part of the evening news the prior night.

Some experiences:

• We got to tour the Trauma Resuscitation Unit which is the emergency department of the trauma hospital. We saw a surgery being performed through some doors but couldn't really see anything in detail.
• We also toured the hyperbaric oxygen (HBO) chamber where patients with necrotizing fasciitis and other serious wounds go to help their wounds heal through concentrated oxygen to help increase blood oxygen content.
• The hospital has a helipad where 3 helicopters can land to bring in patients and we toured that area as well. It was common to hear helicopters landing throughout the day so long as weather allowed. The day we toured the weather was rainy so no helicopters were on the landing area. It's a good thing the internet has photos of everything for me to use!

Internship Rotation 11: Surgical GI, 3 Weeks

Wow, what a rotation! Honestly, I've been a little anxious about this rotation all year. The preceptor is a very well-respected staff member among the clinical nutrition team and throughout the hospital. She covers the Surgical Intensive Care Unit and works with some of the most critically ill patients in the hospital. We spent the majority of our time in the SICU seeing patients as well but did work on a few patients in outside units. This was the first rotation where we worked with patients who required TPN for nutrition support (also explained in one of my January rotations here). This rotation wore me out with a 7:30 am rounds start time in the unit, but I really learned a lot and enjoyed my time working with the preceptor.

Some of the patients we saw: necrotizing pancreatitis, surgical cancer patients, liver transplants, gastrointestinal surgical patients (like colostomies, ileostomies, colectomies, gastrectomies, Nissen fundoplications, esophogectomies, paraesophogeal hernia repairs, and others), ulcerative colitis, intestinal and esophogeal perforations, etc.

Similar to the Medical ICU where I did my enteral rotation, the Surgical ICU is a unit where some of the sickest patients are treated. It was not uncommon to have patients code on a regular basis and to have patients in the unit die, including two of my patients.

Some learning experiences from the rotation:

- Post-op GI patients have a return of bowel function in the following order: small bowel, gastric, then large bowel. To determine when we should start feeding a patient again after surgery we check for bowel sounds, suctioned gastric contents (most patients come out of the OR with a tube from their nose to their stomach just for the purpose of suctioning the secretions back out of their stomach until function returns), then the passing of flatus or stool production.

-Patients can develop an ileus after surgery where portions of their bowel dilate and don't function for an extended period of time.

Quick overview of a paraesophageal hernia:

Paraesophogeal hernia: image showing the stomach herniated through the hiatal covering and sitting next to the esophagus. The stomach is not the only organ that can push up through a hernia opening, intestines and other organs can pop through too. A major issue occurs with a volvulus, or twisting, of the contents in the hernia leading the necrosis of the tissue. One of my patients had this issue and ended up with a gastrectomy, hemicolectomy and partial esophagectomy (so no stomach, part of his intestines removed and part of his esophagus removed). In patients like this the intestines can be directly connected to the esophagus for continued oral feeding.

Up Next: Trauma, 2 Weeks then SPRING BREAK IN COSTA RICA!! I can't wait!

Internship Rotation 10: Oncology, 2 Weeks

We spent this rotation with 4 preceptors so it was a little crazy getting back and forth for patient visits and note co-signing (we sign all of our assessment notes and then the preceptors co-sign before they get put in the medical record). One of the preceptors does only outpatient work so we spent time with her visiting the radiation oncology clinic and meeting with patients who were in for follow-up exams or radiation appointments. One of the preceptors is over the ENT and oral surgery in-patients so we saw cancers of the head and neck with her and the other two cover the in-patient cancer unit where most other cancers are treated. A few things I learned in this rotation:

• Certain cancer treatments can actually be related to the development of other cancers. One of my patients was in remission from breast cancer but then developed leukemia and the thought was that it was related to her chemotherapy for the breast cancer.
• Radiation treatments are like repeated severe sunburns in the same spot for the duration of the treatment (which is typically several weeks or more). The radiation machines are in lead-walled rooms with thick lead doors. The patients are the only people in the room when the machines are running. The systems are so technically advanced that they adjust to the patient's breathing to keep the radiation beam calibrated exactly on the site for treatment.
• Stem cell transplants are now performed instead of bone marrow transplants. Similar cells are transplanted but the techniques are different. Instead of the painful hip donation site portrayed in TV shows or movies, the cells are drawn out in more of an IV type device. The cells can either come from the patient themselves (autologous) or from a matched donor (allogeneic).
• Those who undergo stem cell transplants from a matched donor develop sort of a dual immune system so that two immune systems are fighting off the bad cells. Unfortunately, the donor cells can also fight against the native cells and lead to graft vs. host disease which can be fatal.
• When certain chemotherapy drugs are administered in patient rooms, radiation monitors must be used to check the levels of radioactivity and the rooms are completely covered to keep the chemicals off the floor and furniture. There are large black barrels to hold all waste from the room to ensure that there is no outside contamination.

Types of patients I saw in this rotation: stem cell transplants, breast cancer, leukemia, neck/tonsil cancer, pancreatic cancer, and cancer patients in remission being treated for other illnesses such as infections, and surgical scar resections. As for nutrition therapies for these patients, I worked with intermittent, nocturnal, and continuous tube feedings as well as oral diets. On a side note-this is the first rotation where I actually worked with a prisoner. There were always police guards in the room with the patient and the patient was handcuffed to the bed. I never felt unsafe but it was an interesting situation.

As you may know, my own mother is a breast cancer survivor who underwent chemotherapy and radiation treatments. I was asked by one of the preceptors if this rotation was more difficult for me since I had a personal experience with cancer. I answered that I didn't feel that it was more difficult because my mom had a positive outcome. She's been in remission for a few years now and she tolerated her treatments fairly well. I felt like the rotation was fulfilling because I got to make a difference in helping someone else's family member to have a positive outcome.

Internship Rotation 9: Enteral Nutrition, 4 Weeks

Enteral nutrition refers to nutrition provided through tube feedings. We spent this rotation in the medical intensive care unit (MICU) and the neuro ICU. We worked with patients who could be fed orally still but put most of our focus on patients who needed to be fed through a tube. Tubes can be put through the mouth, nose, or abdominal wall into the stomach or small intestines.

NOTE: This is NOT a picture of a patient from our hospital; it is a picture that I found on the internet. The red arrow is pointing to a nasally-placed feeding tube.

Some experiences from this rotation:

• We watched the placement of a nasojejunal feeding tube for a patient with severe acute pancreatitis. This means that the feeding tube was passed through the patient's nose, through his stomach and into the jejunal portion of his small intestine. Unfortunately, the placement didn't go too well because the patient wasn't very happy to be having a tube crammed down his throat while he was nauseated. Once the placement was done, they did an x-ray (which they always do to make sure we're feeding into the right portion of the digestive tract and not into the lungs) and found that the tube had gotten stuck in his stomach. So, they took it back out and didn't feed the patient (it's not advisable to feed a patient with pancreatitis prior to their small intestine because earlier feeding in the GI tract will lead to pancreatic stimulation. In the case of pancreatitis, the production of more enzymes leads to pancreas autodigestion and breakdown so the patient could potentially lose their pancreas and develop type 1 diabetes).
• We also saw patients who needed Blakemore tubes to stop bleeding in their esophagus. Blakemore tubes are balloons that blow up inside the esophagus to put pressure on bleeding areas similar to compressing a cut to stop bleeding externally.
• We spent some time with a respiratory therapist who showed us all of the options for ventilation. Many of our patients were intubated so learning about the machines attached to them was important for us to use in assessing the clinical status of our patients. We saw patients on ventilators, oscillators, ECMO and other respiratory machines.
• Unfortunately, the unit where we worked this time held many of the sickest patients in the entire hospital. It was not uncommon to have a patient die most days of the week that we were in the unit (including at least two of my patients).
• Types of patients we saw in this rotation: stroke, suicide attempts, alcohol withdrawal, brain damage, seizure, respiratory failure/distress, end stage COPD, pneumonia, trigeminal neuralgia, intracranial hemorrhages (many that had occurred while shoveling snow), pseudo-aneurysm, septic shock, bacteremia, and fungemia. Many patients were intubated and sedated (with propofol, which provides 1.1 calories per mL, some patients were receiving over 1000 calories per day just from their sedation).
• We used many types of feeding formulas such as Jevity 1.2 (the numbers refer to the amount of calories per mL), Osmolite 1.5, Glucerna 1.5, Nepro with Carb Steady, and Oxepa.

Internship Rotation 8: Clinical Management, 1 Week

We spent this week shadowing our internship director who also happens to be the director of clinical nutrition at the hospital. We attended a lot of meetings, and spent time discussing management issues such as discipline, hiring/staffing, and information dissemination. We spent part of our time completing audits of RD and dietetic tech medical record documentation concerning timing and assessment. We also did some research to prepare for the creation of a new clinical nutrition web page for the hospital and spent time taking photos of the staff to use on the new site. The week provided great insight into how the clinical nutrition side of the hospital overlaps with nursing, hospital management, foodservice and other areas of the full facility operation. While attending the manager's meeting we learned that the hospital was canceling their foodservice contract with a big name contract company in order to go to a self-operation, which is a big deal in the world of large scale food operations. We also got to learn how the hospital is getting involved with the Haitian earthquake relief - they're sending rotating teams of physicians and nurses led by the Shock Trauma department (did you know that UMMC is the home of the first Shock Trauma in the nation?).
