< Back Stabbed in the Right Thigh A 42-year-old male is brought to the Emergency Department as a Level 1 trauma activation for a stab wound to the right thigh. He was hypotensive before arrival, with SBP in the 70s-80s. Estimated blood loss of 500 mL on the scene. On arrival, the patient is awake and argumentative. His blood pressure is 90 systolic. On a rapid secondary survey, there is no evidence of any other wounds. There is a tourniquet in place to right upper thigh. When the tourniquet is released, there is arterial bleeding from the wound and there is no palpable distal pulse. What do you need to do before leaving the trauma bay? Replace tourniquet. Call OR to have vascular instrument set available, as well as massive transfusion, cell saver, etc. Type and cross for blood transfusion. After ensuring a type and cross, we proceeded to the operating room. How do you want to prep and drape the patient? Any instructions for anesthesia? Wide prep and drape to ensure adequate access for proximal and distal control- this includes prepping the lower abdomen for possible iliac exposure. Also, need to prep contralateral lower extremity for potential saphenous vein harvest. Ultrasound localization of the saphenous prior to prepping can allow identification of the larger vein. Anesthesia will need to monitor hemodynamics and volume status and be prepared for volume resuscitation with blood. In addition, they will have to be vigilant for the repercussion syndrome, the metabolic disturbance following the re-establishment of arterial flow (washout of toxins following ischemia). We placed a pneumatic tourniquet on the patient's upper thigh. We prepped and draped from the umbilicus to the knees, and also prepped and draped the contralateral thigh to have access in case a saphenous vein harvest was required for repair. We made an incision directly over the wound and dissected down to the artery. There was a single wound in the anterior surface of the distal superficial femoral artery. Proximal and distal control was obtained after circumferentially dissecting and placing vessel loops. The artery was divided and spatulated. It was repaired with an end to end tension-free anastomosis. Following arterial repair, we performed a lower extremity fasciotomy. Management of Penetrating Arterial Trauma WTA Algorithm Diagnostic Workup Hard signs- pulsatile bleeding, thrill, bruit, expanding hematoma, pulse deficit, cold pale limb. These patients require operative intervention. A few exceptions can benefit from preoperative imaging to document the presence and location of associated arterial injuries: wounds in the thoracic inlet, shotgun wounds in the extremities, and segmental fractures or fractures at different levels of an extremity. Soft signs- history of pulsatile bleeding, wound near an artery, non-expanding hematoma, neuro deficit, weak pulse, proximity injury. These patients need further workup to evaluate for the presence of arterial injury. An ankle-brachial index should be performed, and if ≤0.9, CT angiography is indicated. If ABI >0.9- no further w/u needed. ABI <0.9- CTA. Principles of arterial repair 1. Plan incision to facilitate proximal and distal control. 2. Ensure adequate back bleeding. Fogarty to remove distal thrombus. 3. Tension-free anastomosis. Adequate lumen. Clean margins. Don't create more damage to the vessel. 3. Consider risk/ benefit of heparinization. Systemic dose: 70-100 units/kg IV. Regional dose: 50U/ml x50 mL. 4. Completion angiogram to document repair. There are various techniques for creating an anastomosis, but the basic principles must be maintained. Recently, I was taught a useful technique [Dr. Feliciano, AAST 2020 Virtual Conference] that prevents tension at one point along the anastomosis. A parachute technique, starting with loosely approximated sutures on the back wall, followed by parachuting the two ends close to continue the suture on the anterior surface of the artery. Indications for fasciotomy include prolonged limb ischemia (>6 hours), combined arterial and venous injuries. 1. Feliciano DV. Evaluation and Management of Peripheral Vascular Injury. Part 1.

Ratios < Back Kitchen Hacks #5 Ratios Cooking with Ratios Bread 5:3 flour to water- for example, 300g flour and 180g water. With this ratio in your arsenal, the world of bread is at your fingertips. You can explore different flours, hydrations, and additions like seeds and nuts from here. Salt: Around 2% of the flour weight (e.g. 6g salt for 300g flour) Yeast: Around 1% of the flour weight (e.g. 3g yeast for 300g flour) Muffin/Quick Breads 2:2:1:1 flour:liquid:eggs:fat Baker Move: Baking times and temps can vary based on something as simple as the humidity in the air. Pros test the doneness of muffins, quick breads and cakes by simply inserting a toothpick. If it comes out clean, they are ready to cool. Biscuit 3:2:1 flour:liquid:fat Baker Move: Pros always scoop flour, sugar or other dry ingredient into a measuring cup, then use the back of a knife or other straight edge to level it off. Vinaigrette 3:1 oil to vinegar. Add herbs, garlic, or mustard to elevate your dressing Cookies 3:2:1 flour:butter:sugar Other ingredients like eggs, baking powder, and flavourings can be added, but the core 3:2:1 ratio for the main dry, fat, and sweet components is the foundation. Baker Move: Using a dough scoop (like a small ice cream scoop) to portion equal-size cookies adds a professional touch to your finished cookie plate. Pound Cake 1:1:1:1 flour: egg: fat (unsalted butter): sugar Baker Move: Pull your butter and eggs out of the fridge a couple of hours before you're ready to bake. Room-temperature butter is better for creaming, and you'll want the eggs at the same temperature to prevent them from seizing. Pancakes 2 parts flour: 2 parts liquid: 1 part eggs: 1/2-part fat Baker Move: Slowly incorporate the liquid into the dry ingredients while whisking constantly for effortless, lump-free pancake batter. Meringue 2 parts sugar: 1 part egg whites or 1 part sugar: 1 part egg yolks Baker Move: Avoid cracks in your perfectly piped meringues by keeping your oven door closed while they dry out. Yep, that means no peeking. Pie Dough 3:2:1 flour:butter:water Baker Move: Soggy-bottomed pie crusts, be gone! Pros know to par-bake their crusts for fresh fillings. Fritter 2:2:1 flour:liquid:egg Baker Move: The key to a crispy fritter is to never crowd the pan. Drop too many in the frying oil at once and the temperature will plummet, producing a greasy, mushy fritter. Custard 2:1 eggs:liquid Baker Move: Once you have that ratio down, remember to strain your cooked custard through a fine mesh sieve to remove any lumps. Crepes 1/2:1:1 flour:liquid:egg Baker Move: Crepe batter needs time to set up, preferably overnight in the fridge. Links Cooking with Ratios Food Network Previous Next

< Back Guts on the Floor and Exposed Spine Patient #1 A 32-year-old male was involved in a head-on motor vehicle collision. He was ejected and pinned between two vehicles. He was brought in by EMS and on arrival to the trauma bay, he was covered with a sheet. When he was transferred to the gurney, it was clear that there was something unusual. He was eviscerated with a large wound in his right lower abdomen just above his inguinal ligament, and his intestines were entangled in his clothing. Patient #2 A patient was brought in by EMS following a motorcycle accident with a report of "exposed spine". Primary survey unremarkable, hemodynamically stable. FAST revealed fluid in the abdomen. A secondary survey revealed multiple extremity abrasions. When the patient was log rolled, he was noted to have a full-thickness degloving injury of the soft tissue and partial avulsion of the back musculature with exposed spinous processes. What are the management priorities? Prioritize primary and secondary survey, treat life-threatening injuries first. Secure airway. Evaluate for concomitant injuries, including thoracoabdominal injuries, requiring emergent surgical intervention. The challenge of Distracting injuries Remember- very painful or frightening injuries may distract from pressing clinical priorities. Regardless of how horrifying or novel an injury is, the goal of rapid evaluation and management of trauma patients is to identify and treat the most life-threatening injuries first. Remember to evaluate the airway, breathing, and circulation, and don't be concerned with the exposed intestine until you have ensured the patient doesn't have a pending loss of airway, tension pneumothorax, cardiac tamponade, etc. Control active arterial hemorrhage. Don't let the patient die from an unsecured airway while you are frantically attending to grass and flecks of wood and rock covering the exposed back muscle overlying the spine. Previous Next

< Back Shot in the Chest- Aortic Occlusion A 30-year-old male sustained a gunshot wound to his left lower chest/ upper abdomen. On arrival, his heart rate was in the 50s with weakly palpable carotid and femoral pulses. Significantly hypotensive. Penetrating wound to the left lower chest wall with an occlusive dressing in place without ongoing hemorrhage. Initial workup and management? Assess mental status. Secure large-bore peripheral IV access and start massive transfusion. A rapid ultrasound of the chest and abdomen revealed fluid in the left chest, right upper quadrant, and no pericardial fluid. We placed a left chest tube with minimal output. Still hypotensive…treatment options? Resuscitative thoracotomy. Urgent OR if vitals improve with resuscitation. REBOA. A rapid secondary survey revealed a previous midline laparotomy. This would likely impede rapid access for aortic control during laparotomy, so REBOA was placed through a right femoral artery cutdown. With inflation of the REBOA, he had a return of cerebral perfusion with spontaneous movement of his extremities. He was transported emergently to the OR. We encountered massive hemoperitoneum and extensive dense intra-abdominal adhesions that prohibited easy access for a supra-celiac aortic clamp. There was ongoing hemorrhage despite REBOA. Other options to control intra-abdominal bleeding? Procedures directed at source (compression of the liver, splenectomy, etc). Aortic occlusion above the injury- stops all perfusion below the level of occlusion. This can be done from the chest through a left anterolateral thoracotomy or below the diaphragm (supra-celiac clamp). The patient underwent left thoracotomy for aortic cross-clamp. There were no obvious intra-thoracic injuries. Intra-abdominal injuries included a large Zone 1 retroperitoneal hematoma and left diaphragm injury, injuries to solid organs (liver and pancreas) and hollow viscus (stomach, small bowel, and colon). Management of massive sub-diaphragmatic hemorrhage Aortic occlusion decreases distal bleeding and redistributes blood volume to the myocardium and brain. This leads to a reduction in sub-diaphragmatic blood loss. Traditionally, this is accomplished through an open approach, either via thoracotomy or laparotomy. Concurrent with the expanding use of and comfort with endovascular approaches, endovascular occlusion of the aorta (REBOA) has been re-introduced as a less invasive approach. General indications Traumatic life-threatening hemorrhage below the diaphragm (non-compressible torso trauma) in patients in unresponsive shock Zone 1 (distal thoracic aorta)- control of severe intra-abdominal/ retroperitoneal hemorrhage, or for traumatic arrest. Zone 3 (above aortic bifurcation)- severe pelvic, junctional, or proximal lower extremity hemorrhage. Mixed results regarding clinical outcomes. Essentially the same time to aortic occlusion as resuscitative thoracotomy. Not shown to be significantly quicker at obtaining aortic occlusion than resuscitative thoracotomy. Brenner M et al.
