< Back Tips and Tricks General Tips Despite popular belief, you don’t need a daily CXR for every ICU patient, every intubated patient or every patient with pneumonia/ rib fractures. Don't get daily labs or daily imaging "just because". Get studies that will change your management. For stable patients, you don’t need to check a CBC immediately after every transfusion. You don’t need a PaO2 to wean FiO2. PaO2 is an infinitesimally small contribution to arterial O2 concentration. The equation is often simplified by removing it all together! CaO2= (Hgb x SaO2 x 1.38) + (PaO2 x 0.03) ≈ (Hgb x SaO2 x 1.38) Avoid adjusting multiple meds at one time when addressing a symptom (for example, adding a new medication and increasing the dose of another medication). Too many changes at the same time will make it difficult to know what medication change was responsible if there is a clinical change. Most patients don’t need a CXR after chest tube removal. If the pt has PTX that requires a chest tube, they will tell you (meaning they will be symptomatic). If you check a CXR on everyone, you will find small PTXs that don't need treatment. Not everything that hurts/ bleeds is a hemorrhoid. Exam is required to identify the etiology. If you treat a fissure with hemorrhoid meds (witch hazel, suppositories) they won't get better. Plus, witch hazel will burn and suppositories will be incredibly painful. Patients often get better despite us, not because of us. Many things we believe to be optimal treatment now will be considered heresy in the future. Sometimes not doing something is the best thing to do. Sometimes not operating is the compassionate thing for the patient. A patient doesn’t have to die with an incision on their abdomen. Working with your team Trust the nurse when they say they’re concerned. Better to have a phone call for a patient who is ultimately fine vs not getting a call when the patient isn’t fine. If you respond to nurses by telling them it’s fine and not to worry, they will learn not to call you. If you respond to nurses with hostility, they won’t go out of their way to make your life easier. Don’t call your mid level resident/ chief/ fellow/ attending without any more information than you were initially given. When requesting a consult or calling your chief/ fellow/ attending about a new consult/ admit, give the bottom line upfront. This is especially true when you are waking someone up or need them to do something quickly (ie get dressed and drive in). Tips for the OR While closing fascia, if you maintain counter-traction on the fascia with your pickup as you pass the needle through the fascia, you can release the needle while it’s still in the fascia and reload the needle farther back to push it the remainder of the way through the fascia. Then you can reload the needle and be ready for your next bite without having to touch the needle (decrease risk of needle sticks). Ask for instruments and sutures several steps ahead so you minimize pauses. Always ask for cell saver for a bleeding patient heading to the OR. You don’t want to be delayed waiting for it to be set up before you make your incision. Tips in the Trauma Bay Don’t use GCS 8 as an automatic trigger for intubation. If you intubate before addressing hypovolemia or relieving obstructive physiology, there is a high risk of cardiovascular collapse and asystole. Previous Next

< Back Studying Tips Study Techniques Reading and re-reading textbooks/ notes. Pros- simple. Cons- passive. Easy to not absorb information as your eyes pass over the same text. Reading and highlighting textbooks/ notes. Pros- simple. More interactive than merely reading. Cons- similar to re-reading- still relatively passive. Risk of highlighting everything and not focusing on key points. Reading and handwriting notes in your own handwriting. Pros- active engagement in learning, reframe the information in your own style. You can color-code, reorganize, personalize it. Cons- takes more time. When to study There are two key circadian rhythm patterns. In his book When: The Scientific Secrets of Perfect Timing ," Daniel H Pink refers to these as "chronotypes." There are three chronotypes (larks, owls, and third birds), but the differences between them are largely inconsequential, so they are simplified to two different groups, classically known as early bird and night owl. If you haven't identified your chronotype, you can do a few relatively straightforward steps to determine your pattern. Identifying your chronotype will give you a framework to plan your peak time for analytical tasks, such as studying. If you have any control over your daily schedule, even if it's just weekends, take advantage of your inherent pattern to optimize your studying. Early morning studying before class/ clinical rotations might be optimal for some, while others are more conducive to evening learning. What has worked for me? I used to be a read and re-read type. I'm a fast reader, so it worked to get through high school and medical school. During surgery residency, I used iAnnotate PDF, which allows me to highlight and make notes. When I was entering fellowship, I renovated my style. First, I wrote notes for the handful of critical care texts that I read (Fink and Marino) and the trauma text (Mattox). During the summer before my ACS fellowship, I typed notes while reading Fink and Marino. I used iAnnotate PDF because it allows me to highlight and make notes. I did switch to a hard copy of Civetta because I needed a new format to re-ignite my focus. I used old fashioned lined paper and pencil and then rewrote them into a notebook. After I got burnt out on textbooks, I made the leap to reading journal articles. Switching to primary literature was a monumental change in my studying. I always marvel at attendings who can quote journal articles with ease. It always strikes me that their memory is so crisp...I've never had that gift. When I started reading articles, I developed a system for finding, reading, and then recording the salient findings. How I built my literature database for Acute Care Surgery There are several ways to find articles. Surgical Clinics (previously known as Surgical Clinics of North America) is one of my favorite journals for reviewing broad topics. Every article is evidence-based, with abundant references. The most current journals will be a treasure trove of high-yield references. The open journals and published guidelines (read: free!) are another excellent resource. The references in reviews and guidelines are the basis of evidence-based medicine. Read! You don't have to read every word, and as you read more articles, you will develop a sense of which papers can be perused and which deserve a more diligent review, such as landmark articles (see suggested articles). Highlight, make notes and ask yourself, "how will this change my practice". Previous Next

Measuring Cups and Spoons < Back Kitchen Hacks #2 Measuring Cups and Spoons Cooking versus baking…what's the difference? Technically cooking is a general term encompassing all manners of food preparation. But cooking is typically used to indicate a style that doesn't involve baking. Baking is a science that requires attention to detail and precisely measured ingredients that often have to be combined in a specific order. Recipes for baked goods frequently indicate weight in ounces (which required a small countertop scale) as well as volume (measured in your dry measuring cup). On the other hand, cooking allows on-the-fly modifications- it's much more forgiving to small variations. Baking requires precise measurements- so you'll need a variety of dry and wet measuring utensils. If you're unfamiliar with baking, here is a quick summary of how to measure dry and wet ingredients. What are dry measuring cups and how do I use them? These hold the exact amount of an ingredient (you fill these to the top). Either spoon the ingredients into the cup or scoop the cup into the container holding the ingredient (ie wide-mouthed containers). Fill to the top without packing, and level off the top (knife, the handle of a cooking utensil, chopstick, whatever you have). The only ingredient that gets packed is brown sugar- otherwise, unless the recipe specifically mentions packing, don't pack! What are liquid measuring cups or beakers and how do I use them? These have graduated indicators to allow pouring an exact amount of liquid, and the top measurement is below the top of the cup (no spills when pouring). Why can't I just use dry measuring cups for liquids? If you use a dry measuring cup for liquid, it will be very challenging to avoid spilling the ingredient when adding it to the recipe (remember, dry cups get filled to the top). What can I measure with a measuring spoon? Fortunately, these can be used for both dry and wet (although if you have beakers with small measurements, you can also use those for measuring out liquids). Warning about dry ingredients. If a dry ingredient is specified by weight (ounces), this cannot be converted to cups! 8 ounces of flour ≠ 8 fluid ounces of liquid, which is 1 cup of liquid. If you want a visual of the range of what 1 cup of dry ingredients can weigh, check out this extensive list . Previous Next

Practical Tips on Having a Difficult Discussion How Do I Do It? < Back Practical Tips on Having a Difficult Discussion This blog is complementary to the previous blog about becoming more comfortable with uncomfortable conversations. After many difficult discussions with families during my critical care fellowship, I finally became comfortable with uncomfortable conversations. It's impossible to develop a script to use for every conversation, but here are some of the techniques I've adopted over the years. Sit down in a private room, have tissues if appropriate. Make sure your phone/ pager won't interrupt the conversation. Have someone else with you. It’s always good to bring the patient's nurse, and there is often spiritual support staff (ie chaplains) who can accompany you and provide support for the family. Introduce yourself, and ask who everyone in the room is, specifically how they're related to the patient. "Nice to meet you, I'm really sorry it's under these circumstances." If it's your first conversation with the family, it's important to establish a foundation to build on (or establish the absence of a foundation). You can ask "what do you know so far" or "what's your current understanding of the situation"? This also allows them to express their current questions/ concerns. Judge their level of comprehension and adjust as needed. This does NOT mean being patronizing or imposing stereotypes. Pay attention to facial expressions and listen to their questions/ responses. It's easy to fall back into speaking medical jargon- you need to deliberately focus on using easily understandable words. Words that we use every day are meaningless to most people who aren't in the medical field. Keep the conversation brief and take frequent pauses. They don't hear everything you say, and they'll hear even less if you talk non-stop. Allow them time to process what you’ve shared, and allow them to ask any questions they have. Acknowledge that it’s common to be overwhelmed by the discussion. You can validate them by offering "I know I just told you a lot of information" or "I know this can all be overwhelming". It’s also helpful to say, “I’m sure you will think of other questions, please write them down so we can discuss them later” Encourage them to discuss things amongst themselves and provide them a quiet private place to regroup after the meeting. It’s also helpful to say, “I’m sure you will think of other questions, please write them down so we can discuss them later.” This validates their feeling and reassures them that they don't have to worry about remembering every detail. Specific difficult topics - Death and dying. Acknowledge that what they are feeling is normal- regardless of what they feel, it's normal. Denial, angry, scared, guilty, confused, conflicted, exhausted, numb. - When they are wrestling with the decision about transitioning to comfort care (colloquially known as "withdrawal of care", or crassly, "pulling the plug") and they've verbalized that they know it's what their family member would want, acknowledge how difficult that decision can be but also reaffirm that they are doing the kindest thing by honoring their family members wishes. For other helpful tips, check out "Sunburn". "For patients who are alive, concentrate on the ‘big picture’ and avoid the inclination to catalog every injury during this initial encounter. The primary concern in these settings often consists of survival, brain damage, paralyzation and other major morbidities. Again, an overabundance of information can be overwhelming." Velez D et al. SUNBURN: a protocol for delivering bad news in trauma and acute care surgery. Trauma Surg Acute Care Open. 2022 Feb 9;7(1):e000851. Previous Next

14 Scienceblind Why Our Intuitive Theories About the World Are So Often Wrong Intuitive theories- our best guess as to why we observe the events we do and how we can intervene in those events to change them. Infer causality from our observations. Similar to historical theories- how we used to understand things before we had the ability to understand the reality (like heat as an “object” versus “energy”). Emergent process- system wide (no clear cause/ effect explanation), equilibrium-seeking, simultaneous, ongoing. Heat, weather, evolution are all emergent processes. Molecular theory, scientific theory. Holistic theory- matter is continuous and has heft and bulk Intuitive theories of the physical world Matter- substances are holistic and discrete, instead of particulate and divisible. Conservation- clay flattened, water poured from short fat glass to tall skinny glass. The difference between weight and heft, volume and bulk? Energy- heat, light and sound viewed as substance instead of emergent property. Why can you touch the 400 degree air in the oven but not the pan itself (without oven mitts)? The pan transfers heat better than air. How do we change from viewing “sound” as an “object” to viewing it as “energy”? First, we stop attributing permanence (noise doesn’t continue forever), then weight (clock doesn’t become lighter with each chime) and then mass (noise can pass through a wall, doesn’t have to maneuver around wall). Extra-missionist- rays go out of the eye and then return to create vision vs intro-missionist- rays enter the eye to create vision. Gravity- weight is an intrinsic property of objects instead of relation between mass and gravity. Objects don’t fall because they’re heavy- they fall when they don’t have upward force on them that exceeds gravity (center of gravity). Motion- force is something transferred between objections (“impetus”), instead of external factor changing the objects motion. What path will an object take- for example, a ball in a spiral slide- takes straight path after exiting, doesn’t gain an inherent “spiral” motion. Cosmos- earth is a motionless plane orbited by the sun. Changing of the tides, seasons (tilt of the earth as it revolves around the sun, the side closest to the sun is summer). Earth- continents and mountains are eternal and unchanging vs transient/ dynamic. Tectonic plates- similar land features on different coasts. Greenhouse effect and global warming- humans causing it, but the earth will live beyond us. Vitalism- living things possess an internal energy, or life force, that allows those things to move and to grow. Essentialism is the idea that an organism’s outward appearance and behavior are products of its inner nature, or “essence.” Intuitive theories of the biological world Life- animals viewed as psychological agents vs organic machines. Death= cessation of biological processes. Growth- eating is for satiation rather than nourishment, aging is a series of discrete changes vs continuous change. Vitalism- living things possess an internal energy, or life force, that allows those things to move and to grow. Essentialism is the idea that an organism’s outward appearance and behavior are products of its inner nature, or “essence.” Inheritance- parent-offspring resemblance viewed as nurture, vs transfer of genetic information. Illness- disease is due to supernatural causes, instead of microorganisms. Adaptation- evolution is the transformation of an entire population (butterflies become slightly darker with each generation) vs selective survival (darker butterflies survive to reproduce). Ancestry- species develop linearly (monkey→ ape→ human) rather than branching from common ancestor. Previous Next

12 Barking Up The Wrong Tree The Surprising Science Behind Why Everything You Know About Success Is (Mostly) Wrong - Good grades in school- likely to be a "rule follower", and less likely to be innovative, think outside the box. - Introverts are more likely to be experts, extroverts tend to make more money (socializing, "networking"). We should look at "networking" as "making friends". This disputes the "nice guys finish last"... - Match your strengths/ passion/ skill to the right context. - Flattery (sucking up to the boss) can work in the short term, but in the end, when people see their colleagues/ neighbors/ etc cutting corners and reaping benefits, this leads to a general collapse into distrust and rule-breaking. - IQ only matters up to a certain point, but then it yields diminishing returns. After that, hard work is what makes the difference. - Tradeoffs- every hour that you spend working is an hour spent away from other things (family, hobbies). In this age of constant accessibility, you have to decide to leave work behind (ignore your emails when you're at your kid's ball game). - Gratitude in relationships- on their deathbed, people regret working too much and not saying thanks to the people in their life. - Some helpful things I learned...please note that tact and delivery matter and these are not appropriate in every scenario. - When someone is getting upset or frustrated and starts yelling, "Please speak more slowly, I want to help." Or try, "What would you like me to do?" - When someone is upset, validate/ name their feeling. "Sounds like you’re angry/ hurt/ frustrated." If you're wrong, give them the chance to correct you. - Gratitude to relationships. Previous Next

How not to lose everything < Back Organizational Hacks How not to lose everything All my life, I've been forgetful and easily distractible. I joke that I'd lose my head if it wasn't attached. This challenge is part of my ADHD, and I can't overcome it with sheer willpower. The list of things that I've lost over the years is staggering- homework (oh so much homework…it was usually stuffed somewhere in my locker), clothing, books, charging cables, water bottles, earrings (what am I supposed to do with the remaining single earrings?) and a white polar bear stuffed animal (he was left in a hotel room on a road trip as a child). I'm looking forward to learning where all my things went when I die and go to heaven. So if this can’t be overcome with sheer willpower, how can you adapt? Check out these techniques or tools to see if you find something that would be useful for yourself. Information * Create a tool for yourself for storing the data you need to be able to access reliably. This website is full of high-yield medical information that is rapidly accessible, but a website is a labor-intensive option. You don’t have to invest time and money into a website. Here are some other options (check out this post for more details ): - Invest in a planner . Electronic options that sync are useful because they minimize the need to re-write things in multiple places. Another option that I prefer is one notebook that keeps all my events in one place, along with my collection of lists and reminders. - Write everything down. My planner is my note repository. The Apple Notes application is also useful because it can sync across multiple Apple devices. At home or work, dry-erase poster paper can be used to take notes, keep track of schedules and provide reminders for long-term tasks and due dates. - Trello is a user-friendly free application with multiple functions, including the creation of lists, storage of documents, and the ability to share notes or documents among team members/ family members. Items * Magnet strips . Using magnetic sheets the size of business cards, cut pieces and strips to put on various items and stick them to the fridge or other magnetic surface of your choice. For example, if you use dry-erase poster paper on the refrigerator, thin strips of magnet can be cut to fit along the length of several dry eraser markers, so they're always on hand when you have something to jot on the whiteboard * Keys on a hook by the front door. 3M hooks work well, but the hook design isn’t as important as placement, ideally not in direct sight of the door. You can also hang your work ID badge or any other small items you need when you leave the house. * Keep track of all your cords with these tie wraps . Inexpensive and sturdy. I didn’t think there was any way I’d use 50- I figured maybe a couple, just for a handful of my charging cables that always end up in a jumble. But trust me, you'll find plenty of uses for them! Finances and Important Documents * Save receipts for anything valuable. If it was purchased online, download the digital receipt. Use the "Create PDF" function to combine receipts. For paper receipts, an envelope in a drawer is a simple option. Every so often, review the receipts, and if there is anything you don't need anymore, toss it. * Paper shredder . Anything with personal information should be destroyed before being thrown away. This is technically not about avoiding losing something, but it’s an important task so it is included here. * Taxes. Instead of waiting until tax season, keep track of key documents and expenses throughout the year. A running spreadsheet of business expenses, donations, etc, can avoid the frantic search in March. * Metal rack of hanging file folders. Each folder has a different label, including taxes (donation receipts, investment statements, etc), moves (signed leases, welcome packet with key information, etc), and business (bank paperwork, original EIN and registration forms, deposited checks).

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.).

< Back Ultrasound: Cardiac Exam Purpose: identify possible causes of hemodynamic instability, respiratory distress, assessment of volume status. Probe The phased array can be used for the entire exam. The curvilinear can also be used for the subxiphoid and IVC views. Views There are 4 basic views, including the parasternal long axis, parasternal short axis, the apical four chamber and the subcostal view. Additionally, the inferior vena cava can be visualized. Cardiac ultrasound is more challenging to learn than most other ultrasound studies, because probe usage (position, angle, rotation, translation, etc) have drastic impact on visualization. It’s necessary to understand what is shown in each view, so take time reviewing these so you can have a better appreciation for what you are seeing when you perform a study on a real patient. One recommendation, if it is difficult to visualize the heart, moving the patient into the lateral decubitus with their left side down can significantly improve visualization as the heart is closer to the chest wall in this position. For video and pictorial explanations of the views, please refer to these sites. Basic Cardiac Views, #1 Basic Cardiac Views, #2 Findings Gross abnormalities- decreased ventricular function, arrhythmias Profound hypovolemia Small hyperdynamic left ventricle with end-systolic collapse Inferior vena cava- assess volume status, either static measurement of diameter or calculation of collapsibility (>50% correlates with volume responsiveness). Respiratory variation (collapsibility/distensibility index). Takotsubo cardiomyopathy Akinesia of the apical and mid-ventricular segment, hypercontractile basal segments. Apical sparing (dilated). Acute cor pulmonale Respiratory disorder→ pulmonary hypertension→ right heart failure. Dilated right heart. Cardiac tamponade Effusion with end-diastolic collapse of the right atrium, effusion in front of the aorta Pulmonary embolism Free-floating thrombus in the right ventricle or pulmonary artery; right ventricular dilation/ systolic dysfunction; septal bowing into the left ventricle; dilated IVC without inspiratory collapse. Most sensitive/ specific indirect sign- right ventricular apical sparing (McConnell's sign).
