Trauma Practice Questions

Q: A 40-year-old woman sustains a 20% total body surface area burn. She presents with hypotension and tachycardia. What is the most appropriate initial fluid therapy?

Lactated Ringer's. ***Lactated Ringer's*** - **Lactated Ringer's solution** is the **resuscitation fluid of choice** for burn patients per the **Parkland formula** - Its composition is similar to **extracellular fluid**, effectively restoring fluid and electrolyte balance - Contains **lactate** which is metabolized in the liver to **bicarbonate**, helping counteract the **mild acidosis** often seen in burn patients - Isotonic crystalloid that provides adequate **intravascular volume expansion** in hypovolemic shock *Incorrect: D5W* - **D5W (5% Dextrose in Water)** is a **hypotonic solution** that primarily distributes into the **intracellular compartment** - Does not effectively expand intravascular volume necessary for resuscitation - Inappropriate for patients with **significant burns and hypovolemia** requiring urgent volume replacement *Incorrect: Normal saline* - While **normal saline (0.9% NaCl)** is an isotonic crystalloid, large volumes lead to **hyperchloremic metabolic acidosis** due to high chloride content (154 mEq/L) - Can exacerbate existing acidosis in burn patients - Less physiologically balanced than Lactated Ringer's for burn resuscitation *Incorrect: Plasma* - **Plasma** is a colloid solution **not used for initial fluid resuscitation** in the acute burn phase - Reserved for specific situations: **severe hypoproteinemia** or **coagulation factor deficiencies** - Carries risks including **allergic reactions** and **transfusion-related acute lung injury (TRALI)** - Not part of standard burn resuscitation protocols

Q: In trauma surgery, what is the primary concern when a patient presents with hard signs of vascular injury?

Surgical exploration and possible vascular repair. ***Surgical exploration and possible vascular repair*** - The presence of **hard signs of vascular injury** (e.g., pulsatile bleeding, rapidly expanding hematoma, thrill, bruit, absent pulses distal to injury) indicates an acute, limb-threatening or life-threatening situation requiring **immediate surgical intervention**. - **Surgical exploration** allows for direct visualization, control of bleeding, and **definitive repair** of the damaged vessel, which is crucial to prevent ischemia, hemorrhage, and subsequent limb loss or patient demise. *Immediate administration of anticoagulants* - Administering **anticoagulants** in the setting of acute vascular trauma with active bleeding is **contraindicated** as it would exacerbate hemorrhage, leading to significant blood loss and hemodynamic instability. - Anticoagulation is typically used in situations to prevent clot formation, not to manage active vascular injury. *Ultrasound assessment of the affected limb* - While **ultrasound** can be useful for diagnosing vascular injuries, in the presence of **hard signs**, it is generally **not the primary initial step** because it delays definitive treatment. - The urgency of hard signs necessitates immediate surgical intervention, and confirmatory imaging like ultrasound should only be considered if it does not delay transfer to the operating room. *Observation and reassessment in 24 hours* - **Observation** for a patient with **hard signs of vascular injury** is **highly inappropriate** and dangerous, as these signs indicate an active, critical condition. - Delaying intervention by 24 hours would likely result in irreversible **ischemic damage**, limb loss, or potentially fatal hemorrhage.

Q: What is the initial management for a patient with a suspected spinal cord injury at the scene of the trauma?

Immobilization of the spine. ***Immobilization of the spine*** - The primary goal at the scene of trauma with suspected spinal cord injury is to prevent further damage to the spinal cord. **Immobilization** using devices like a cervical collar and long backboard minimizes movement and protects the injured area. - This step is critical to preserving neurological function and is the **first and most important intervention** in prehospital care. *Administration of steroids* - Historically, high-dose **corticosteroids** (e.g., methylprednisolone) were used, but current evidence does not support their routine use due to lack of significant benefit and potential for serious side effects like **gastrointestinal bleeding** and **sepsis**. - Steroid administration is a medical decision made in a hospital setting, not an initial management step at the scene of trauma. *Immediate surgery* - **Surgery** for spinal cord injury is performed in a hospital setting, often to decompress the spinal cord, stabilize the spine, or reduce fractures. - It is not an initial management step at the scene of the trauma, where the focus is on **stabilization** and safe transport. *Pain management* - While **pain management** is important, it is secondary to **spinal immobilization** and stabilization in the immediate prehospital setting. - Administering analgesics without proper immobilization could mask neurological symptoms or compromise assessment.

Q: In managing a patient with a large burn injury, what is the primary goal?

Fluid resuscitation and hemodynamic stabilization. ***Fluid resuscitation and hemodynamic stabilization*** - The immediate and most critical goal in managing large burn injuries is to restore and maintain **circulatory volume** to prevent **burn shock**. - Large burns lead to significant fluid shifts and electrolyte imbalances, making aggressive **fluid resuscitation** essential for survival. *Immediate surgical debridement* - While important, surgical debridement is typically not the **primary initial goal** and is often delayed until the patient is hemodynamically stable. - Performing extensive surgery on an unstable patient can lead to further **hemodynamic compromise** and increased risk. *Prevent infection* - Infection prevention is a crucial ongoing concern in burn management, but it is secondary to establishing **hemodynamic stability**. - A patient in shock is at a higher immediate risk of death than one developing a superimposed infection. *Pain management* - Pain management is a vital component of patient comfort and care, but it does not address the immediate **life-threatening physiological derangements** caused by large burns. - While important, pain control should not overshadow the priorities of **resuscitation** and stabilization.

Q: What type of burn injury is characterized by a deep red or cherry red coloration of the skin due to thermal injury?

Superficial partial thickness burn. ***Superficial partial thickness burn*** - This burn extends into the **superficial dermis** and is characterized by a **deep red or cherry red appearance** due to dilated and damaged but still perfused capillaries. - The surface is typically **moist and weeping** with **prominent blisters** containing clear fluid. - These burns **blanch with pressure** and are **extremely painful** due to exposed nerve endings. - Classic example: severe scalding injury. *Superficial burn* - Also called first-degree burns, these only affect the **epidermis**. - Appears as **light red or pink** (like sunburn), not the deep cherry red of superficial partial thickness. - **No blisters** form, and the burn is dry with intact skin. *Deep partial thickness burn* - Extends into the **deep dermis** with a characteristic **mottled appearance** (pink, white, or waxy white). - Surface is typically **dry** rather than weeping, as deeper capillary damage reduces exudate. - **Less painful** or even painless due to partial nerve ending destruction. - May have **sluggish or absent blanching**. *Full thickness burn* - Destroys all skin layers including the entire dermis and sometimes subcutaneous tissue. - Appears **white, brown, leathery, or charred** — never cherry red. - **Completely painless** at the burn site due to complete nerve destruction. - No blanching occurs as there is no viable circulation.

Q: A 25-year-old male presents with a deep partial-thickness burn on his forearm. What is the initial management step?

Cooling the burn. ***Cooling the burn*** - **Cooling the burn** with tepid (room temperature) water is the immediate first aid step for a partial-thickness burn to reduce pain, decrease edema, and limit the depth of injury. - This should be done for 10-20 minutes, careful to avoid **hypothermia**, especially in larger burns or young children. *Debridement* - **Debridement** involves removing dead or contaminated tissue and is performed after initial cooling and assessment, typically in a clinical setting. - It is crucial for wound healing and infection prevention but is not the very first immediate step. *Fluid resuscitation* - **Fluid resuscitation** is critical for larger or deeper burns (typically >15-20% TBSA for adults) to prevent **burn shock** and maintain organ perfusion. - It is not the immediate first aid step for a localized, deep partial-thickness burn on the forearm. *Skin grafting* - **Skin grafting** is a surgical procedure used for deep second-degree burns that are unlikely to heal on their own or for third-degree burns. - It is a definitive treatment option, typically performed days to weeks after the injury, not an initial management step.

Q: In trauma surgery, what is the initial fluid of choice for resuscitation?

Ringer's lactate. ***Ringer's lactate*** - **Ringer's lactate** is an **isotonic crystalloid solution** that closely resembles the electrolyte composition of plasma, making it the initial fluid of choice for resuscitation in trauma patients. - It effectively restores **intravascular volume** and corrects dehydration without causing major fluid shifts. *Hypertonic saline* - **Hypertonic saline** is typically used in specific situations like **traumatic brain injury** to reduce intracranial pressure, not as the initial fluid for general resuscitation. - It can cause rapid intracellular dehydration and **hypernatremia** if not used carefully. *Albumin* - **Albumin** is a **colloid solution** and is generally reserved for patients with severe hypoalbuminemia or refractory hypovolemia after crystalloid resuscitation has failed. - It is more expensive and has not shown superior outcomes over crystalloids for initial trauma resuscitation. *Fresh frozen plasma* - **Fresh frozen plasma (FFP)** is a blood product used to correct **coagulopathy** in bleeding trauma patients, not for initial fluid resuscitation. - It contains clotting factors but is not an ideal volume expander and carries risks associated with blood transfusions.

Q: A patient with a basilar skull fracture may present with Battle's sign. What does Battle's sign indicate?

Bruising behind the ears; temporal bone fracture. **Bruising behind the ears; temporal bone fracture** - **Battle's sign** is ecchymosis or **bruising over the mastoid process**, which is located behind the ear. - It is a classic indicator of a basilar skull fracture involving the **temporal bone**. *Bruising around the eyes; frontal bone fracture* - Bruising around the eyes (**raccoon eyes**) is indicative of a basilar skull fracture, but typically suggests a fracture of the **anterior cranial fossa** (orbital roof, frontal bone). - Battle's sign specifically refers to bruising behind the ear. *Blood in the sclera; ethmoid bone fracture* - **Subconjunctival hemorrhage** (blood in the sclera) can occur due to head trauma, but it is not specifically referred to as Battle's sign. - While an **ethmoid bone fracture** can lead to orbital trauma, it is not the primary association with Battle's sign. *CSF rhinorrhea; sphenoid bone fracture* - **Cerebrospinal fluid (CSF) rhinorrhea** is the leakage of CSF from the nose, often indicating a fracture in the anterior or middle cranial fossa involving the **cribriform plate** or **sphenoid bone**. - This is a different sign than Battle's sign, which is purely ecchymosis.
