Trauma Practice Questions

Q: In blunt trauma abdomen, maximum injury to the small bowel occurs at:

Proximal jejunum. ***Proximal jejunum*** - The **proximal jejunum** is particularly vulnerable to blunt abdominal trauma due to its relatively fixed position at the **ligament of Treitz** and its proximity to the impact forces. - The rapid change in momentum during deceleration can cause tearing or shearing injuries at this point of relative immobility. *Ileocecal junction* - While the ileocecal junction is another relatively fixed point, it is less commonly injured in blunt abdominal trauma compared to the proximal jejunum. - Its anatomical position often shields it from the direct impact and shearing forces that typically affect the more superior small bowel. *Mid ileum* - The **mid ileum** is generally more mobile within the abdominal cavity, making it less susceptible to the shearing forces that affect fixed segments. - Injuries to this region are usually associated with more severe, widespread trauma or direct crushing mechanisms, rather than a specific point of maximum vulnerability. *Proximal ileum* - Similar to the mid ileum, the **proximal ileum** also has considerable mobility, reducing its risk of injury from acceleration-deceleration forces. - The more common sites of injury in the small bowel are those with relative fixation points, such as the jejunum near the ligament of Treitz.

Q: A patient presented with bleeding from thigh and broken 5th rib on right side. What should be done first:

Control bleeding. ***Control bleeding*** - In trauma cases, **hemorrhage control** is the immediate priority to prevent exsanguination and hypovolemic shock, which can be rapidly fatal. - The **ABCDE approach** in trauma management (Airway, Breathing, Circulation, Disability, Exposure) dictates that controlling life-threatening bleeding falls under "Circulation" and often takes precedence over other injuries once the airway is secured. *Strapping of chest* - While a fractured rib can cause pain and impair breathing, **chest strapping** is generally not recommended as it restricts chest wall movement, potentially leading to **atelectasis** and **pneumonia**. - Furthermore, it does not address the immediate life threat of uncontrolled bleeding from the thigh. *Internal fixation of rib* - **Internal fixation** of a broken rib is an advanced and elective surgical procedure, typically performed significantly later for specific indications such as flail chest or non-union. - It is not an emergent intervention and would be performed only after the patient is stable and all life-threatening conditions, including active bleeding, have been addressed. *Wait & watch* - A "wait and watch" approach is inappropriate for a patient with active bleeding and a fractured rib, as it delays critical interventions and can lead to **deterioration** of the patient's condition. - Immediate assessment and intervention are required to manage both the bleeding and the potential respiratory compromise from the rib fracture.

Q: A 30-year-old female with a history of burns involving abdomen, both limbs, and back presented after 8 hours. Which of the following is the formula for calculation of fluid infusion:

4 mL/kg × % TBSA over 24 hours. ***4 mL/kg × % TBSA over 24 hours*** - This is the **Parkland formula**, the gold standard for burn resuscitation in adults. - The total fluid requirement is **4 mL/kg × % TBSA**, with **half given in the first 8 hours** from the time of burn and **half in the remaining 16 hours**. - Since this patient presented after 8 hours, the resuscitation timeline needs adjustment, but the formula itself remains the standard Parkland calculation. - This provides adequate **fluid resuscitation** while minimizing risks of under-resuscitation or fluid overload. *3 mL/kg × % TBSA* - This formula provides **insufficient fluid volume** for adequate burn resuscitation in adults. - Using only 3 mL/kg would lead to **under-resuscitation**, risking hypovolemic shock and inadequate tissue perfusion. - This is significantly below the evidence-based Parkland formula requirement. *5 mL/kg × % TBSA* - This fluid resuscitation rate is **excessive** and significantly higher than the standard Parkland formula. - Using this amount increases the risk of **fluid overload, pulmonary edema**, and **abdominal compartment syndrome**. - Over-resuscitation can be as harmful as under-resuscitation in burn patients. *2 mL/kg × % TBSA* - This formula provides **grossly inadequate fluid resuscitation** for major burns in adults. - This represents only **half of the Parkland formula** requirement and would result in severe under-resuscitation. - Using this reduced volume could lead to **hypovolemic shock, renal failure**, and increased mortality.

Q: In the primary survey, which of the following is not included?

CECT to look for bleeding. ***CECT to look for bleeding*** - A **CECT scan** is a detailed imaging study that is performed during the **secondary survey**, not during the primary survey. - The primary survey focuses on the immediate **ABCDE assessment** (Airway, Breathing, Circulation, Disability, Exposure) to identify and treat immediately life-threatening conditions. - While identifying bleeding is critical, detailed imaging like CECT is done only after initial stabilization is achieved in the primary survey. *ABC* - **Airway, Breathing, and Circulation (ABC)** are the fundamental first three components of the primary survey. - These represent the immediate priorities for life support in trauma management according to ATLS guidelines. - Ensuring a patent airway, adequate breathing, and circulatory stability are critical first steps. *Exposure of the whole body* - **Exposure** (the "E" in ABCDE) is an essential part of the primary survey. - Complete exposure allows full assessment for injuries and prevents missing critical external wounds. - This step also involves maintaining **thermoregulation** to prevent hypothermia. *Recording BP* - **Recording blood pressure** is a crucial part of assessing circulation (the "C") during the primary survey. - It helps quickly evaluate hemodynamic status and identify potential signs of shock or internal bleeding. - Vital signs monitoring is integral to the initial trauma assessment.

Q: For open pneumothorax which of the following is management of choice?

ICD with underwater seal. ***ICD with underwater seal*** - An **intercostal drain (ICD)** with an **underwater seal** is the definitive management for an open pneumothorax once the initial wound has been covered. - This system allows air to escape the pleural space but prevents its re-entry, helping the lung to re-expand. *Wait and watch.* - This approach is suitable for very small, **stable spontaneous pneumothoraces** when the patient is asymptomatic, which is not the case for an open pneumothorax. - In an open pneumothorax, air continuously enters the pleural space, leading to **tension pneumothorax** and rapid deterioration if not addressed promptly. *Thoracostomy and close the rent* - **Thoracostomy** (creation of a surgical opening into the chest) might be part of the overall management, but simply closing the rent without addressing the underlying pneumothorax, often with a drain, is incomplete. - The immediate priority for an open pneumothorax is to convert it into a **closed pneumothorax** and then drain the air. *IPPV* - **Intermittent positive pressure ventilation (IPPV)** with a high enough pressure can worsen an open pneumothorax by forcing more air into the pleural space if the wound is not sealed. - While mechanical ventilation might be needed for respiratory failure, it's not the primary or sole management for the open pneumothorax itself and can be dangerous without proper sealing and drainage.

Q: First treatment of flail chest is

O2 administration and analgesia. ***O2 administration and analgesia*** - The immediate priority in flail chest is to ensure adequate **oxygenation** and manage pain to allow for effective ventilation and prevent respiratory compromise. - **Analgesia** helps reduce pain during breathing, improving tidal volume and reducing the risk of atelectasis and pneumonia. *Mechanical ventilation* - While mechanical ventilation may be necessary in cases of severe respiratory distress or failure, it is not the **first-line treatment** for all flail chest patients. - Its use is indicated if initial supportive measures like oxygen and analgesia fail, or if there's evidence of **respiratory acidosis** or persistent hypoxemia. *Intrapleural analgesia* - This is a form of advanced pain management and is typically not the initial step in treating flail chest. - While effective for pain control, it requires specific expertise and equipment, making it a **secondary intervention** after basic analgesia and oxygen. *Surgical stabilization* - Surgical stabilization of the fractured ribs is considered when there is significant chest wall deformity, persistent respiratory failure despite other treatments, or in cases of non-union. - It is an **elective procedure** and not the immediate first treatment for flail chest.

Q: Which among the following is the best method to assess adequacy of fluid resuscitation in a polytrauma patient:

Urine output. ***Urine output*** - **Urine output** is a direct and real-time reflection of **renal perfusion**, which is highly sensitive to changes in circulating blood volume and cardiac output in trauma patients. - Maintaining a urine output of **0.5-1 mL/kg/hr** is generally accepted as a key indicator of adequate fluid resuscitation and organ perfusion in polytrauma. *CVP* - **Central Venous Pressure (CVP)** can be influenced by multiple factors beyond fluid status, such as **intrathoracic pressure**, **venous tone**, and **right ventricular function**, making it an unreliable sole indicator. - While it offers some insight into preload, CVP measurements alone do not provide a direct and dynamic assessment of **end-organ perfusion** in trauma. *Pulse rate* - **Pulse rate** is a non-specific indicator that can be affected by pain, anxiety, medications, and other systemic responses beyond fluid status in polytrauma. - While **tachycardia** often suggests hypovolemia, a normal pulse rate does not guarantee adequate fluid resuscitation, especially in patients with compensatory mechanisms. *BP* - **Blood pressure (BP)** is a relatively late indicator of hypovolemia in trauma, as compensatory mechanisms can maintain BP near normal despite significant blood loss. - Relying solely on BP can lead to delayed recognition of **inadequate resuscitation** and potential end-organ damage.

Q: Which one of the following is a secondary brain injury?

Intracerebral haematoma with raised intracranial pressure. ***Intracerebral haematoma with raised intracranial pressure*** - **Intracerebral haematoma** is a potentially treatable, secondary injury directly contributing to **raised intracranial pressure (ICP)**, leading to further brain damage if not managed. - **Secondary brain injuries** occur minutes to days after the initial impact, resulting from a cascade of events like ischaemia, oedema, and intracranial hypertension. *Diffuse axonal injury* - **Diffuse axonal injury (DAI)** is a **primary brain injury** caused by shearing forces at the moment of impact. - It is a direct consequence of the initial trauma, not a subsequent physiological process. *Cortical lacerations* - **Cortical lacerations** are **primary injuries**, representing a direct tearing or cutting of brain tissue due to the initial traumatic force. - These are immediately present at the time of injury and are not a consequence of subsequent physiological changes. *Brainstem and hemispheric contusions* - **Contusions** are localised areas of bruising on the brain, characteristic of a **primary brain injury**, occurring directly from the impact. - While contusions can evolve and contribute to secondary injury mechanisms like oedema, the contusion itself is a direct result of the initial trauma.

Q: Neurological status is assessed under which step of ABCDE of trauma care?

D - Disability: neurological status. ***D - Disability: neurological status*** - The "D" in ABCDE trauma assessment specifically stands for **Disability**, which involves a rapid assessment of the patient's **neurological status**. - This step typically includes evaluating **level of consciousness** using tools like the AVPU scale (Alert, Voice, Pain, Unresponsive) or the Glasgow Coma Scale (GCS), assessing pupillary response, and identifying any gross motor deficits. *C - Circulation with haemorrhage control* - This step focuses on assessing and managing **blood flow**, including evaluating heart rate, blood pressure, capillary refill, and controlling any sources of external hemorrhage. - While neurological issues can result from poor circulation, the primary assessment of the nervous system itself is not performed here. *E - Exposure: completely undress the patient and assess for other injuries* - This final step involves a thorough **inspection of the entire body** to identify hidden injuries, such as bruising, lacerations, or deformities, while simultaneously ensuring temperature regulation. - It is for overall physical assessment, not for initial neurological evaluation. *B - Breathing and ventilation* - This step involves assessing the patient's **respiratory effort**, checking for symmetrical chest rise, listening to breath sounds, and intervening to ensure adequate oxygenation and ventilation. - While critical for brain function, this step focuses on the respiratory system, not the direct assessment of neurological function.
