  • Emergency Medicine – Trauma: What You Need to Know Whiteboard Animation Transcript with Kaushal Shah, MD
    Emergency Medicine – Trauma: What You Need to Know Whiteboard Animation Transcript with Kaushal Shah, MD Trauma comes in two basic varieties: blunt trauma and penetrating trauma. Nonetheless, major trauma patients should always be approached the same way: primary survey followed by a secondary survey. Don’t let the blood and gore distract you. The primary survey entails a systematic assessment using ABCDE in order to identify the true life-threatening injuries and initiate resuscitation. Then a detailed head-to-toe exam should occur, which we call the secondary survey. A. Airway assessment. If blood, vomit or the patient’s own saliva is blocking the airway (which often occurs in unconscious patients), they will need suctioning and possibly intubation. B. Breathing. Examine the chest through inspection, auscultation, and palpation. You are looking for life-threatening injuries. Decreased breath sounds, subcutaneous emphysema, broken ribs, and tracheal deviation, are concerning for a tension pneumothorax, hemothorax, pulmonary contusions, flail chest, and cardiac tamponade. C. Circulation. If the patient has a fast heart rate or low blood pressure, suspect ongoing hemorrhage or blood loss, the number one cause of preventable death in trauma. Bleeding is likely in one of four locations: chest, abdomen, pelvis, or fractured long bones. Start IV fluids or blood transfusion through two big intravenous lines. D. Disability. A basic neurologic assessment will help you calculate a GCS or Glasgow Coma Scale. It evaluates Eye Opening, Verbal Response, and Motor Response that is universally understood on a 15-point scale. E. Exposure. The patient should be completely undressed to look for all injuries.

  • Effect of Hypothermia on Haemostasis and Bleeding Risk: a Narrative Review

In this narrative review, we highlight trauma, surgery, and mild induced hypothermia as three clinically important situations in which the effects of hypothermia on haemostasis are important. In observational studies of trauma, hypothermia (body temperature <35C) has demonstrated an association with mortality and morbidity, perhaps owing to its effect on haemostatic functions. Randomised trials have shown that hypothermia causes increased bleeding during surgery. Although causality between hypothermia and bleeding risk has not been well established, there is a clear association between hypothermia and negative outcomes in connection with trauma, surgery, and accidental hypothermia; thus, it is crucial to rewarm patients in these clinical sit- uations without delay. Mild induced hypothermia to 33C for 24 hours does not seem to be associated with either decreased total haemostasis or increased bleeding risk.

  • General Approach to Traumatic Injuries
    Cambridge University Press 978-1-108-45028-7 — The Emergency Medicine Trauma Handbook Edited by Alex Koyfman , Brit Long Excerpt More Information Chapter General Approach to 1 Traumatic Injuries Ryan O’Halloran and Kaushal Shah Introduction Trauma is the fourth leading cause of death overall in the United States and the number one cause of death for ages 1 to 44 – second only to heart disease and cancer in those older than 45 (CDC).1 As the disease burden from infectious diseases declines and secondary preven- tion of chronic conditions improves, the relative importance of the practice of trauma care becomes even more apparent. Though safety engineering has improved across many indus- tries (one need only consider examples such as crosswalk and bike lane planning, football helmet technology, and motor vehicle computerized improvements), trauma remains a significant threat to life and limb in emergency medicine. The Trauma Team The American College of Surgeons, the governing body for credentialing trauma centers, has provided guidelines for optimal resources necessary for a coordinated response to a critically injured trauma patient. Box 1.1 demonstrates the players suggested for an optimal response. While response teams may vary, several principles are key to the functioning of a good, interdisciplinary team. These include clearly establishing roles for members of the team, following policy and protocols established in advance, briefing prior to the arrival of the patient, and debriefing after the event, whether immediately after the event

Abdominal arterial and vein injuries occur with the same incidence. Patients with retroperitoneal vascular injury and intact retroperitoneum may present hemodynamically stable due to tamponade. The main goal of staged approach is to control any major haemorrhage into the abdomen until the patient is hemodynamically stabilized in the ICU and reconstruction can be done in final reoperation. Multidisciplinary management is imperative to prevent the “lethal triad” and assures the best optimal outcome for these critically wounded patients. Introduction Abdominal vascular injuries are the most common cause of death after penetrating abdominal trauma. Blunt injuries to major abdominal vessels are rare. Major injuries to large vessels in the abdominal zone 1 usually cause significant hemoperitoneum and shock. The type of clinical presentation varies widely and depends on the presence of retroperitoneal tamponade. Patients with an intact retroperitoneum may be hemodynamically stable on presentation but when the OPEN ACCESS retroperitoneum tamponade is lost, signs of shock and acute hypovolemia are present. Many patients with major abdominal vascular injuries require massive blood transfusions, are hypotensive, *Correspondence: and become severely hypothermic, acidotic, and coagulopathic intra operatively.

  • Monitoring the Coagulation Status of Trauma Patients with Viscoelastic Devices Yuichiro Sakamoto*, Hiroyuki Koami and Toru Miike
    Sakamoto et al. Journal of Intensive Care (2017) 5:7 DOI 10.1186/s40560-016-0198-4 REVIEW Open Access Monitoring the coagulation status of trauma patients with viscoelastic devices Yuichiro Sakamoto*, Hiroyuki Koami and Toru Miike Abstract Coagulopathy is a physiological response to massive bleeding that frequently occurs after severe trauma and is an independent predictive factor for mortality. Therefore, it is very important to grasp the coagulation status of patients with severe trauma quickly and accurately in order to establish the therapeutic strategy. Judging from the description in the European guidelines, the importance of viscoelastic devices in understanding the disease condition of patients with traumatic coagulopathy has been widely recognized in Europe. In the USA, the ACS TQIP Massive Transfusion in Trauma Guidelines proposed by the American College of Surgeons in 2013 presented the test results obtained by the viscoelastic devices, TEG® 5000 and ROTEM®, as the standard for transfusion or injection of blood plasma, cryoprecipitate, platelet concentrate, or anti-fibrinolytic agents in the treatment strategy for traumatic coagulopathy and hemorrhagic shock. However, some studies have reported limitations of these viscoelastic devices. A review in the Cochrane Library published in 2015 pointed out the presence of biases in the abovementioned reports in trauma patients and the absence of a quality study in this field thus far. A quality study on the relationship between traumatic coagulopathy and viscoelastic devices is needed. Background of hemorrhagic shock that accounts for 90% of incidents Two of the major causes of coagulopathy in trauma of traumatic shock. Since coagulation abnormality which patients are coagulopathy secondary to hemorrhagic is a physiological response to massive bleeding frequently shock due to massive bleeding and coagulopathy due to occurs after severe trauma and is an independent pre- severe head injury [1].
