10 Loonshots How to Nurture the Crazy Ideas That Win Wars, Cure Diseases, and Transform Industries - S type and P type loonshots. Innovators (creating loonshots) have to co-exist with the “businessmen”- you can’t just segregate different groups. The innovators need the company to make a profit so they can continue to take risks and make discoveries. And the business needs to nurture loonshots. - In case you were wondering how polarizing crystals were discovered. Or check out this article in Science magazine. - Bad decisions may occasionally result in good outcomes. But you need to analyze wins- you might not be so lucky next time. - Good decisions may result in bad outcomes. You made the best decision with the information at your disposal. In those same circumstances, you’d make that same decision. - How do crickets synchronize their chirps? - Percolation. A mathematical explanation for predicting events based on an inherent variable. - How do forest fires spread? Relevant variables- the distance between trees, humidity, wind. - How do pandemics start? How appropriate…depends on the proximity of individuals. - Phase transitions - Why do traffic jams occur? Just above a certain density of cars on the roads→ jam. - Emergence- innate characteristics of how a group functions based on the size (ie what patterns shift after the group reaches a size, although the precise size is variable for groups) While individuals remain puzzles, man in the aggregate becomes a mathematical certainty. Meaning- group dynamics are universal, regardless of the characteristics of the group members. Previous Next

[Editorial inspired by @kari_jerge] Why Don't They Believe Us? < Back [Editorial inspired by @kari_jerge] Seen on Twitter recently: Troll: I demand pictures of your full ICU to prove to me it’s full Female surgeon: None of us owes you a damn thing. Especially not pictures that will get us fired. But I’ll get right on that… What do you do if you accidentally injure yourself while working or making home improvements? Do you call 911 or have someone drive you to the ER? What do you do if you have high blood pressure, or diabetes, or depression? Do you go to a primary care doctor? What do you do if you have severe arthritic hip pain that doesn't resolve with conservative (non-operative) management? Do you consider talking to an orthopedic surgery about a hip replacement? I don't know what portion of the population inherently trust the medical community, but for the remainder of this editorial, I will presume that it's a majority. For those that don't, this doesn't apply. If you don't trust modern medicine, I won't convince you that you should trust our reports about this pandemic. Let's assume you accept modern medicine, including visiting the emergency department, having a primary care doctor, taking prescription medicine, and any of the other various diagnostic tests, consultations, and treatments. If this is the case, why would you think we would voluntarily try to deceive you about the capacity and occupancy of our ICU facilities? Why would so many medical community leaders actively speak out with a nearly singular voice to spread a lie? Ranging from the widely known Dr. Sanjay Gupta to a wide assortment of medical providers in many specialties. We have nothing to gain from building this whole façade. This isn't just a few people speaking up. This is a monumental effort to warn people. Social media has given a voice- and many have worked very hard to dispel the myths spread by many loud voices that continue to spread falsehoods. We have nothing to gain. You trust us to save your life when you have a heart attack, need emergency surgery, or care for you when you're severely ill from any matter of diseases. We haven't changed as a community to collectively spread these myths. It really is as bad as we say. We genuinely don't get paid more for patients who die from COVID. We don't have adequate PPE. We aren't lying. If you continue to deny reality, we will still care for you or your family and friends, in the unfortunate case you become ill, because that's what we do. We are just hoping that we will have the resources you need. And if we stretch our personnel any thinner, we will not have enough nurses and providers to care for you. We are the last hope. Don't make choices you'll regret. Previous Next

What is ACS? A day in the life of an Acute Care Surgeon. FAQs. ICU Rounds. Trauma Surgery. Acute Care Surgery What is Acute Care Surgery? Medicine, particularly surgery, has become increasingly specialized, with providers developing progressively narrower expertise. Previously, surgical critical care fellowship was the primary pathway for specialization in the management of critically ill and injured patients. Management of "sick" surgical patients, regardless of the underlying surgical etiology, requires flexibility in addition to width and breadth of knowledge to manage a wide spectrum of clinical challenges, including deranged physiology and complex surgical pathology. Balancing an acutely hemorrhaging patient, an elderly patient with severe poly-trauma, a ventilator-dependent patient with an acute abdomen...the list is endless. Acute Care Surgery (ACS) was brought about to ensure that there is access to a specialized physician that can manage a spectrum of critically ill patients, including trauma, emergency general surgery (EGS), and surgical rescue . Surgical rescue involves the management of procedural complications or clinical situations that require emergent surgical intervention: "airway emergency, hemorrhage, intestinal obstruction, perforated viscus, tube/line/device dysfunction, uncontrolled sepsis with a surgical etiology, visceral ischemia, and wound complication." Management can include the following interventions: "airway intervention, biliary repair/ reconstruction, bowel resection, hernia repair, hemorrhage control, source control of infection, surgeon-guided resuscitation, tube/line/device repair, and wound debridement."(1) Pillars of Acute Care Surgery 1.

Brain Death and Organ Donation End of Life Issues < Back Brain Death and Organ Donation Death can be uncomfortable and challenging to face/ navigate. Here are some of the situations that can arise surrounding the issue of death and organ donation. - Is resuscitating a patient with a devastating TBI for organ donation preservation justified? It may seem opportunistic and NOT focused on the dignified care of the patient- but it the patient’s desire would be to donate, preserving that option DOES honor their wishes. - If a patient is declared dead, specifically brain dead or death by neurologic criteria, and they previously expressed desire to be an organ donor (such as registration with an OPO or indicating their desires on their drivers license), legally the family can’t prevent the patient from donating. Even if the family opposes it, legally the patient should proceed to donation. But what about the risk of “bad press”? You’re honoring the patients wishes although that fact may be less apparent to the public compared to the anger expressed by the family members that the hospital “stole their loved one’s organs against their wish” or even worse, implying that the hospital “allowed” the patient to die so they could use their organs. - You don't need consent to perform a brain death test.

6 Start with Why How Great Leaders Inspire Everyone to Take Action - Explains the importance of developing a shared philosophy for business, teams, and frankly, any mission. It relays a vital concept, but the text is unnecessarily repetitive- it could be significantly shorter while maintaining the message. - Regarding a business model- your "why" is your basic underlying philosophy, motivation, and guiding principle, your "how" is your process, and your "what" is your product. - You can convince customers to buy your newest product, but you have to re-create your marketing with each novel concept. Loyal customers buy your product because they believe in your philosophy. Think about Apple. They don't sell a product. Apple customers will purchase the next Apple product, not because of the particular design or nuanced update, but because they believe Apple's "why." - Ask an employee or a teammate- what do you do? Is their answer a description of their daily tasks? Or is it a message, a principle that guides their action? - If your company's "what" becomes obsolete, your company becomes outdated. If your company was created to copy written text manually, you would be unlikely to adapt to the new technology that successfully automates the process. If your company's "why" was focused on the value of literature and facilitating easy access to books for everyone, this will allow you to remain relevant regardless of how the world changes.

< 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.

< Back Machete Attack- Neck Trauma A 42-year-old male was brought from an outside hospital after sustaining deep, extensive penetrating wounds to the neck and forearms. When he arrived at the hospital, we noted defensive wounds on his forearms and a deep laceration across the anterior neck. The report from EMS was that the patient was assaulted with a machete. What are the management priorities? Prioritize primary and secondary survey and treat life-threatening injuries first. Don't be distracted with impressive wounds. Secure the airway and control active hemorrhage. He was initially seen at a small community hospital, where an endotracheal tube was placed through the tracheal wound, and then he was transferred to our facility. He was rapidly transported to the operating room for evaluation. What structures need to be evaluated? Vascular structures (carotid arteries, vertebral arteries, jugular veins) and upper airway/ digestive structures (esophagus, pharynx). The head and neck team was consulted, and they evaluated him in the operating room. The wound's extent was explored thoroughly. Surprisingly, there were no injuries to the vascular structures, and the injury was isolated to the airway. The endotracheal tube was exchanged for a formal tracheostomy and a stent was placed in the upper airway to prevent luminal narrowing while the repair healed. The wound was closed in layers. Management of Penetrating Neck Trauma WTA Algorithm Anatomy Zone 1 Clavicles/ sternum to cricoid Zone 2 Cricoid to angle of mandible Zone 3 Angle of the mandible to the skull base Hard signs- airway compromise, massive subcutaneous emphysema/air bubbling through the wound, expanding or pulsatile hematoma/ active bleeding, shock, neurologic deficit, hematemesis. Soft signs- hemoptysis, blood in the oropharynx, dyspnea, dysphagia, dysphonia, subcutaneous air, chest tube air leak, non-expanding hematoma, bruit/ thrill. Hard signs or hemodynamic instability→ ensure airway and transport to OR. No immediate operative indications? Depends on symptoms and the zone of injury. Zone 1 and 3- CTA to rule out vascular and aerodigestive injuries; assess the trajectory of injury. Injury→ repair. Concerning trajectory→ triple endoscopy (laryngoscopy, bronchoscopy, and esophagoscopy). Zone 2- symptomatic→ OR. Asymptomatic- serial exams or imaging. Operative approach The most common incision for exploration of neck wounds is along the anterior border of the sternocleidomastoid (SCM) muscle. Exposure of Zone 1 and 3 are more challenging and endovascular adjuncts are useful. Zone 1 may require median sternotomy with extension along the SCM. Zone 3 requires mobilization of the mandible. Zone 2 can be approached with a transverse cervical collar incision with SCM extension. - Tracheal injuries are repaired with monofilament absorbable suture. - Esophageal injury- debride unhealthy edges, ensure full exposure of mucosal defect, repair defect (single or double layer), buttress with SCM, or strap muscle. Place drain. - Combined tracheoesophageal injury- repair, and ensure repairs are isolated with interposition of a well-vascularized muscle flap. Previous Next
