< Back The Trauma Bag Why was there a need for a trauma bag in the hospital? As an acute care surgeon responding to trauma activations, airway emergencies, and a variety of other hospital surgical emergencies, there are a handful of supplies that I always have with me. The two basics are a scalpel for surgical airways and trauma shears (classically used to remove clothes in the trauma bay, but I seem to find more uses all the time). Eventually, I added a Kelly clamp to my armamentarium- handy for disconnecting or unscrewing a wide variety of impossibly tight connections or securing something in place. During the COVID Pandemic, numerous changes were made in our hospital to minimize infection transmission. Unfortunately, several of the modifications had unintended negative consequences. When we stopped wearing white coats, we lost our pocket space for stashing scalpels and shears. We also carried more gear, including eye protection and N-95 masks (carried in a brown bag when not worn). Many surgeons adapted by using an assortment of bags, such as sling backpacks or CamelBak cases. My own choice is this fanny pack , which draws many compliments! The next challenge was the relocation of supplies from the wall of our trauma bay onto shelves in the hallway. Team members had to leave the trauma bay, locate which cart the item was on, and then scan for the item, which created delays. This disrupted communication as well because team members missed changes when they were outside the room. Another hurdle that existed even before the pandemic was the array of different names for the same item. Most people who place cotton-tipped applicators in their ears after their shower call them by the brand name “Q-tip”…they are actually called “cotton tip applicators” or “CTA”. **Note- don’t use Q-tips in your ears!** Drop the Q-tip! Why ENTs are begging you to leave your ears alone. The surgeon might ask for 4x4s, which is what we call gauze in the operating room. Some say "Quik-Clot” while others know the product by the name “Combat Gauze”. Sutures are a whole other bag of worms…do you use silk or Ethibond to secure your chest tube? Curved or straight needle? Countless times, the trauma chief is managing the trauma and when someone calls for a suture, their attention is often diverted to advising the person reaching into the suture box on the wall.…"no, the one to the left, top row." It’s not always easy to tell from the box what the suture and needle look like. In addition to the elimination of white coats, relocation of commonly used supplies outside the trauma bay, and different names for supplies, I noticed that several key items were frequently used and they seemed to be unreasonably challenging to locate in a timely fashion. Combat Gauze, Coban, specific suture on a specific needle, etc. Therefore, I created a backpack of supplies that I carry when on call. What does this bag do? This bag was created from my perception of a necessity to ensure specific supplies are readily available when responding to surgical emergencies. A Level 1 trauma center is equipped with the highest level of resources and personnel to manage the most complex patients, and our resources and patient population dictate what supplies are needed on a routine basis. My focus was on supplies that are (1) frequently used, (2) unique and not readily available in all locations where they are used, and when they are required, (3) delays in employment are remarkably morbid, and (4) portable. Why didn’t I include tourniquets? They’re frequently used and delays in employment are morbid, but patients typically have them in place on arrival and if not, they are readily available in the trauma bay. Why didn’t I include chest tubes? They are frequently used and delays in employment are morbid, but they are relatively widely available. In addition, the life-threatening physiology of hemothorax or pneumothorax can be resolved with a finger thoracostomy using a scalpel and Kelly (essentially the same process as placing a chest tube, but stopping at the step of a finger sweep in the thoracic cavity, releasing massive hemothorax or tension pneumothorax). Why didn’t I include a REBOA kit? This is a controversial topic. However, in the situation where resuscitative thoracotomy is deferred in favor of REBOA, rapid employment is ideal. However, this device is not frequently used at our facility. Paper clips? In a trauma bag? Yes, paper clips. They are used to mark wounds for creating a road map of the trajectory. What DOESN’T this bag do? This is NOT an all-inclusive bag for responding to all emergencies. It should not be considered a guide for pre-hospital emergency response, non-surgical emergencies, or any situations outside of the specifications reviewed above. There are other response teams in the hospital that have different supplies. For example, we have ICU nurses that respond to rapid response or code blue situations, and they carry critical care transfer bags. I don’t know the list of supplies that they carry, but here is a sample of potential contents of a “transfer bag”. In summary, my trauma bag is focused on specific needs that I perceived based on my daily work at my facility. If you perceive a need for a similar tool at your facility, I would encourage you to develop a supply list tailored to your needs.

1st day in radiology: your right is your left, your left is your right Radiologic Dyslexia < Back 1st day in radiology: your right is your left, your left is your right I have recently coined a new phrase. While showing my mom a picture, pointing out someone she had never met before, I commented, "he's the one on the right." Funny story, though- he was actually on the left side of the picture. I had to pause while I talked to my mom and reassure her that I know the difference between my right and my left. While scrolling through Twitter the other day, I was reviewing a question posed about an abdominal x-ray. Another Twitter user added a helpful hint by indicating "the right side of the circle" when pointing out an abnormality. I predicted he meant anatomical right (meaning the image's left side) based on my interpretation. We chuckled about the discrepancy between radiographic laterality and left-right differentiation in real life. I decided to designate this mix-up "radiologic dyslexia." Feel free to use this in the appropriate context! Previous Next

< Back Free Fluid in the Abdomen A 62-year-old male presents following a motor vehicle collision in which he was an unrestrained driver. He was intubated in the trauma bay for decreased mental status. A focused assessment with sonography for trauma (FAST) was performed, which did not reveal intra-abdominal fluid. Computed tomography (CT) of the head demonstrated minimal intra-cranial injury. CT of the abdomen and pelvis (see below) revealed decreased blood supply to the left kidney, small irregularity of the splenic contour, and a moderate amount of free fluid in the abdomen and pelvis. Hounsfield units are consistent with simple fluid. CT of the abdomen and pelvis https://video.wixstatic.com/video/3b6ff6_b03419943e9941d281c3d8f0b800e37f/480p/mp4/file.mp4 What is the differential diagnosis for the free fluid in the abdomen? Free fluid due to trauma can be urine, enteric contents (bowel injury with spillage of succus) or blood. It is possible to have fluid present prior to the trauma, such as ascites from chronic liver disease. In this case, the free fluid in the abdomen had characteristics of “simple fluid,” based on Hounsfield units, suggesting that the fluid was not blood. In females, free fluid in the pelvis can be normal (physiologic fluid). However, free fluid is NOT normal in a male, and it's concerning for hollow viscus injury. What are the possible causes of decreased blood flow to the kidney? The renal artery can be injured in blunt trauma. Blunt injury can disrupt the layers of the artery wall, leading to thrombosis and decreased blood flow beyond the injury. He was admitted to the intensive care unit. A foley catheter was placed and demonstrated pink-tinged urine [NOT frank gross blood/ clots]. What are the possible causes of blood-tinged urine? Bloody urine indicates a traumatic injury to the genitourinary tract, anywhere from the kidneys down to the urethra. A CT cystogram was performed, which did not reveal any extravasation of contrast from the bladder. CT Cystogram https://video.wixstatic.com/video/3b6ff6_119074429b224cc98677d4f101fef666/480p/mp4/file.mp4 Next steps? Based on an unreliable physical exam and a normal CT cystogram, it is necessary to rule out bowel injury. The patient was hemodynamically stable and had normal laboratory values. He remained with a decreased mental status, and therefore serial abdominal exams were not a viable management plan. The patient was taken to the operating room and underwent diagnostic laparoscopy. His small bowel, colon, and mesentery were examined in there entirety and found to be completely normal. There was a small amount of clear thin fluid in the pelvis, but there was no evidence of bile staining or bleeding. After completing the evaluation of the gastrointestinal tract, we repositioned the patient in Trendelenburg. The pelvis was inspected, and it was quickly apparent that the patient in fact had a large defect in the dome of the bladder. We elected to proceed with a low midline laparotomy. The bladder was easily mobilized, and the extent of the defect was defined. The edges were grasped, and the defect was closed in two layers with absorbable suture. Postoperatively, we reviewed the preoperative CT cystogram. In retrospect, there was a suggestion of bladder irregularity. We reviewed the CT cystogram with the radiologist and there was no evidence of contrast extravasation. However, the bladder does not appear to have been completely distended with contrast. It is very atypical that a large bladder wall defect was not associated with contrast extravasation, and this highlights the importance and ensuring complete filling of the bladder with contrast. Evaluation and Management of Bladder Injuries Bladder injuries can occur from blunt or penetrating trauma. For example, bladder injuries can occur when blunt force is exerted on a full bladder or in the setting of a pelvis fracture. Diagnosis Gross hematuria is seen in most patients with bladder injuries. Cystography, either using plain x-ray or CT, is the diagnostic test of choice. Management The management of bladder injuries is based on location. Intra-peritoneal injuries require operative management. This is done in two or three layers with absorbable suture. A decompressive foley catheter is left following repair. Extra-peritoneal injuries can typically be managed non-operatively with a foley catheter for 10-14 days. Exceptions include large bony segments protruding into the bladder wall, associated rectal or vaginal injuries, bladder neck injuries, or an associated pelvic fracture undergoing operative intervention to prevent hardware contamination. Current guidelines recommend a cystogram before foley removal, except for the most uncomplicated injuries. Yeung LL et al.

Medical Literature Evidence-Based Medicine After you have established a firm foundation of the basics of your chosen specialty, you're ready to develop regular habits to stay up to date on the newest research. Evidence-based medicine is the basis of high-quality patient care, but it can seem overwhelming to try to keep up with the ever-growing body of research. There are countless journals, and it would be time-consuming to search them regularly. So how does one go about navigating the vast ocean of available data? Registering for email alerts is a simple way to get notified when there are new publications. With a quick skim through the article titles to see if anything is relevant, followed by a review of the abstract/ article itself, you can be on the cutting edge of the latest information in your field. Several require individual registration, but it's a very simple and quick process. Many journals require a subscription, often available through your medical school or hospital library. If you are military, you have access to AMEDD Virtual Library (abundant medical resource collection). Thankfully, three publishers (LWW Wolters Kluwer , Springer and Elsevier ) have centralized their journals, so you can quickly subscribe to several journals [these journals are designated by L, S or E].

Surgery trainee education. Trauma surgeon. Acute Care Surgery. FAQs Why did you make this website? Over these years of learning about the practice of surgery, I've also learned a lot about myself. I am not an expert, and I did not follow a typical pathway- but I have some knowledge and resources to share. As I transition into my new Acute Care Surgeon role after 17 years in training, I'm pausing to share my experience, tips for success, and random nuggets of wisdom. This will be a work in progress, and I look forward to seeing how it evolves. My goal is to share my experience and knowledge in the hopes of helping those who desire to follow this path. But why do we need another medical education website? There are so many good resources already... There are endless ways to explain clinical concepts- pictures, text, analogies, clinical cases, podcast discussions of cases or principles, review articles, etc. There are also different learning styles. When I was trying to grasp advanced ventilator management, I read basic critical care textbooks, a book dedicated solely to ventilator management, and various websites and journal articles. This website is another way to interact with the information. Hopefully you will understand some of the concepts in a new way that helps you remember and apply them in clinical scenarios. In addition, I have also tried to create a comprehensive collection of all the useful resources I know, like apps and open access medical education resources (websites, clinical guidelines, etc) in one place for trainees to What does Doc on the Run mean? The summer before my last year of medical school was the start of my running career. My focus was enjoying the outdoors, not pace or distance. During my residency, I met someone who helped me refine my running. I started timing myself, training, and racing. Within a year or two, I pushed through personal barriers to become a "runner." My first half marathon was on Thanksgiving in my third year of surgical residency. I am at the end of my formal training, I am now an Acute Care Surgeon. As a surgeon, there are numerous factors that I can't control. It's fast-paced, demanding, and dynamic. I enjoy the organized chaos and high-stakes cases. Running is key to my work-life balance. Unlike in the operating room or the trauma bay, I have control over most aspects of my runs- pace, distance, route, and thoughts. It's not chaotic- it's basically the polar opposite of my work. During the day, my mind is going a million miles an hour. When I run, everything becomes clearer- I can solve problems, mull over ideas, or process dilemmas. And perhaps the most concrete impact is the runner's high that I enjoy after finishing. I have continued to run 10Ks, 10 milers, and the occasional 5K or 15K. I have learned more about the science of running (HR training zones, different paces for tempo/ interval/ long runs/ short runs) and I've learned how to adapt training schedules to fit my life. Unfortunately, I have suffered my share of injuries, including most recently nerve impingement in my foot. While I may have scaled back, running will always be part of my identity. Did you really build this website yourself? Yes, I did. No, I didn't do all the intricate coding by myself. But I did design, format, and create the content. So are you a computer/ technology guru? Whatever I know about technology, I learned from my brother and from spending many hours researching problems online. While my parents might consider me an expert, I literally just search online to solve most issues. When I get to the end of the internet and still haven't found the solution, my next step is Apple tech support (obviously only if the problem is with my iPhone or Mac). What did you learn while making this website? - Formatting the working space on a website - URL redirect - Domains and subdomains - Search engine optimization (SEO) - Establishing custom domains - Which text/ background colors are easiest to read - Anchors If you weren't an Acute Care Surgeon, what would you do? I'd be a chef. I love cooking! Is there anything that is overwhelmingly gross in your job? I have had almost every body fluid on me- stool, urine, blood, etc. So very little grosses me out. But I can't stand oral or nasal secretions (aka saliva, slobber, snot, etc.).
