Trauma Practice Questions

Q: Consider the following conditions in blunt trauma of the chest : 1. Flail chest 2. Drainage of 1 litre of blood from the chest tube 3. Cardiac tamponade 4. Rupture of oesophagus Which of the above are the indications of emergency thoracotomy?

2, 3 and 4 only. ***Correct: 2, 3 and 4 only*** **Emergency thoracotomy indications in blunt chest trauma:** **Drainage of 1 litre of blood from chest tube (Massive Hemothorax):** - Definite indication for emergency thoracotomy - Standard criteria: >1500 mL initial drainage OR >200-300 mL/hr for 2-4 consecutive hours - 1 liter initially approaches the threshold and indicates ongoing hemorrhage requiring surgical control **Cardiac tamponade:** - Life-threatening condition requiring immediate intervention - Initial management may include pericardiocentesis, but if patient is in extremis or pericardiocentesis fails, emergency thoracotomy is indicated - In the setting of blunt trauma with hemodynamic instability, thoracotomy may be necessary for definitive repair **Rupture of oesophagus:** - Though rare in blunt trauma, when it occurs it requires surgical repair via thoracotomy - While not always an immediate "emergency" in the resuscitation bay, it does require urgent surgical intervention once diagnosed - Can lead to mediastinitis and requires thoracotomy for repair and debridement *Incorrect: Flail chest (Statement 1)* - **Flail chest is NOT an indication for emergency thoracotomy** - Management is primarily conservative: adequate analgesia, pulmonary toilet, and respiratory support - Surgical rib fixation (ORIF) may be considered in select cases but this is different from emergency thoracotomy for hemorrhage or cardiac injury - Flail chest does not require opening the chest cavity emergently; it's a chest wall injury managed supportively *Incorrect: 2 and 4 only* - Excludes cardiac tamponade, which is a critical indication for thoracotomy in unstable patients *Incorrect: 1, 2, 3 and 4* - Incorrectly includes flail chest, which is not an indication for emergency thoracotomy *Incorrect: 1, 2 and 3 only* - Incorrectly includes flail chest - Excludes esophageal rupture which does require surgical thoracotomy when diagnosed

Q: A 23-year-old male riding his motorcycle meets with a road accident. He is tachypnoeic with HR 110/min and BP 112/74 mmHg. On examination, he appears pale and has tenderness over the left side of chest with dullness to percussion. There is slight mediastinal shift to the opposite side. Abdominal examination is unremarkable. Most probably he is suffering from:

Haemothorax. **Haemothorax** - **Dullness to percussion** on the left side of the chest, combined with symptoms of **hypovolemia** (pale, HR 110/min, BP 112/74 mmHg), strongly suggests blood accumulation in the pleural space. - **Slight mediastinal shift** to the opposite side is consistent with a large volume of blood pushing the mediastinum, though it's typically more pronounced in tension pneumothorax. *Tension pneumothorax* - Characterized by **hyperresonance** to percussion, not dullness, as air accumulates in the pleural space. - Would present with marked **tracheal deviation**, **severe respiratory distress**, and often severe hypotension due to impaired cardiac output. *Subcutaneous emphysema* - Identified by **crepitus** (crackling sensation) on palpation due to air in the subcutaneous tissues. - While it can be associated with chest trauma, it does not explain the dullness to percussion or the systemic signs of blood loss. *Tracheal rupture* - Typically presents with **severe subcutaneous emphysema**, **dyspnea**, **hoarseness**, and possibly a **pneumomediastinum**. - Does not directly cause dullness to percussion in the pleural space or explain the significant signs of blood loss.

Q: Glasgow Coma Score Scale pertains to:

Level of consciousness. ***Level of consciousness*** - The **Glasgow Coma Scale (GCS)** is a neurological scale that aims to give a reliable and objective way of recording the conscious state of a person [1]. - It assesses a patient's motor, verbal, and eye-opening responses to determine their **level of consciousness** [1], [3]. *Chest injury* - The GCS is not designed to assess **chest injuries**; other trauma scores like the Injury Severity Score (ISS) are used for that purpose. - Chest injuries are evaluated through physical examination, imaging like **X-rays** and **CT scans**, and assessment of respiratory function. *Head injury only* - While GCS is crucial for assessing **head injuries**, its primary focus is on the patient's **overall level of consciousness**, which can be affected by various conditions beyond isolated head trauma [1], [2]. - Conditions like metabolic disturbances, drug overdose, and shock can also alter consciousness and are monitored using GCS [1], [4]. *Head and cervical injury* - The GCS evaluates the **level of consciousness**, which is a systemic response, not specific to a combined head and cervical injury. - While head injuries often coincide with cervical spine precautions, the GCS itself does not directly assess the presence or severity of a **cervical injury** [4].

Q: In a male patient of road traffic accident with blood at the tip of external meatus, the likely injury is:

Injury to urethra. ***Injury to urethra*** - **Blood at the tip of the external meatus** is a classic sign of urethral injury, often occurring in male patients following a **pelvic fracture** from a road traffic accident. - This symptom indicates a direct tear or disruption of the urethral continuity, allowing blood to exit through the penile meatus. *Injury to urinary bladder* - Bladder injuries typically present with **hematuria** (blood in the urine), but rarely with blood at the external meatus unless there is an associated urethral tear. - Patients might also experience **suprapubic pain**, difficulty voiding, or anuria. *Injury to kidney* - Kidney injuries often cause **gross hematuria** (visible blood in urine) but do not typically result in blood at the external meatus directly. - Other signs include flank pain, tenderness, and sometimes a palpable mass. *Injury to all of these* - While multiple injuries can occur in a severe road traffic accident, the specific presentation of **blood at the tip of the external meatus** is highly indicative of a urethral injury, making it the most likely isolated injury suggested by this particular symptom. - There is no direct evidence presented in the question to suggest simultaneous injury to the kidney and bladder leading to this specific sign.

Q: A 50 year old patient had a haematoma in his left gluteal region which was large, painful and causing some neural deficit. The next plan of management will be to:

Incise or aspirate the haematoma. ***Incise or aspirate the haematoma*** - A large, painful hematoma, especially one causing **neurological deficits**, requires intervention to relieve pressure and prevent further damage. - **Incision and drainage** or **aspiration** are appropriate surgical methods to remove the collected blood and alleviate symptoms. *Apply some superficial ointment for it to subside* - **Superficial ointments** are ineffective for large, deep hematomas, particularly when they are causing **neurological compression**. - This approach would not address the underlying pressure or the potential for **tissue damage** from the hematoma. *Get an CECT or MRI done* - While imaging like **CECT or MRI** can provide detailed information about the hematoma's size, location, and relationship to surrounding structures, it is a **diagnostic step, not the definitive management** for an already established, symptomatic hematoma. - Given the patient’s symptoms, especially **neurological deficits**, prompt intervention to relieve pressure is more critical than immediate advanced imaging. *Leave it alone* - Leaving a large, painful hematoma with **neural compromise** unattended can lead to **permanent nerve damage**, **compartment syndrome**, or other severe complications. - This approach is appropriate only for small, asymptomatic hematomas that are expected to resolve spontaneously without complications.

Q: Which one of the following regarding management of acute wounds is NOT true?

Clamps should be used to stop all bleeding vessels. ***Clamps should be used to stop all bleeding vessels*** - While **hemostasis** is crucial, using clamps on *all* bleeding vessels, especially small ones, is generally discouraged as it can cause **tissue damage** and may not be necessary for effective bleeding control in many acute wound settings. - The primary initial goal is to achieve **hemostasis** safely, often through direct pressure, elevation, and pressure dressings, before more invasive measures. *Wounds should be examined, taking into consideration site and structures damaged* - A thorough examination is fundamental to identify the **extent of the injury**, including potential damage to underlying structures like nerves, tendons, vessels, or joints. - This assessment guides the appropriate cleaning, debridement, and repair strategies to optimize **healing and function**. *Bleeding wounds should be elevated and a pressure pad applied* - **Elevation** helps reduce hydrostatic pressure, thereby decreasing blood flow to the injured area. - Applying **direct pressure** with a pressure pad is the most immediate and effective method for controlling venous and capillary bleeding, and often arterial bleeding as well. *The whole patient should be examined according to ATLS principles* - The **Advanced Trauma Life Support (ATLS)** principles prioritize a systematic approach to trauma care, starting with the primary survey (ABCDE) to identify and manage life-threatening injuries. - This ensures that hidden or more critical injuries are not missed amidst the focus on the visible wound, maintaining a **holistic view** of the patient's condition.

Q: Indications of computed tomography after head injury include all EXCEPT:

Mild head injury in a 50 year old man. ***Mild head injury in a 50-year-old man*** - This is not an absolute indication for CT scanning after head injury, especially if the patient is **neurologically intact** (GCS 15) and has no other high-risk features. - While age **> 65 years** is considered a risk factor in some guidelines (Canadian CT Head Rule), age 50 alone does not warrant CT in mild head injury (GCS 13-15) without additional warning signs. - CT would be indicated if this patient had **other risk factors** such as loss of consciousness, amnesia, vomiting, anticoagulation use, or dangerous mechanism of injury. *Open depressed fracture* - This is a **high-risk feature** indicating a severe head injury and potential for **intracranial injury** or infection, requiring immediate imaging. - CT is essential to assess the extent of **bone depression**, foreign bodies, and associated brain injury. *Glasgow Coma Scale 30 minutes* - **Post-traumatic amnesia (PTA)** lasting longer than 30 minutes is a recognized risk factor for **intracranial injury**, even in patients with otherwise normal GCS scores. - It indicates a more significant impact on brain function and warrants a CT scan to rule out **structural lesions** per NICE and Canadian CT Head Rules.

Q: Mainstay of an accurate diagnosis of pancreatic injury following blunt abdominal trauma is:

Computed Tomogram. ***Computed Tomogram*** - **CT scan** is the **imaging modality of choice** for evaluating solid organ injuries, including the pancreas, following blunt abdominal trauma due to its rapid acquisition and high resolution. - It effectively identifies signs of pancreatic injury such as **lacerations**, **hematoma**, **peripancreatic fluid**, and **transection of the pancreatic duct**. *USG abdomen* - **Ultrasound** has limited utility in diagnosing pancreatic injury due to the gland's **retroperitoneal location** and frequent overlying bowel gas obfuscating views. - While useful for rapid assessment of free fluid, it is **not sensitive enough** to reliably detect subtle pancreatic parenchymal damage. *MRI abdomen* - **MRI** provides excellent soft tissue contrast but is typically **time-consuming** and less accessible than CT in acute trauma settings, making it impractical for initial evaluation. - It may be used for **further characterization** of an injury, especially ductal involvement, if CT findings are equivocal or in stable patients. *Diagnostic peritoneal lavage* - **Diagnostic peritoneal lavage (DPL)** is primarily used to detect **hemoperitoneum** or rupture of hollow viscous organs, but it is **not specific for pancreatic injury**. - A positive DPL can indicate intra-abdominal injury but doesn't localize the source, and it has largely been replaced by focused assessment with sonography for trauma (FAST) and CT scans.

Q: A patient of road traffic accident presents to the emergency with increasing restlessness and difficulty in breathing. The respiratory rate is 26 breaths/minute; there are distended neck veins; trachea is deviated to the right side with hyper-resonant note and absence of breath sounds on the left side. Which of the following statements are correct? 1. The most probable clinical diagnosis is left tension pneumothorax 2. Immediate chest decompression using wide bore cannula in left 2nd intercostal space is to be done 3. Immediate chest X-ray should be done to confirm the clinical diagnosis 4. Definitive chest tube insertion in left fifth intercostal space should be done

1, 2 and 4. ***1, 2 and 4*** - The clinical presentation with **increasing restlessness**, **difficulty in breathing**, **distended neck veins**, **tracheal deviation away from the affected side** (to the right for a left-sided collection), **hyper-resonant note**, and **absent breath sounds on the left** is pathognomonic for **left tension pneumothorax** (Statement 1 is correct). - **Immediate needle decompression** with a wide-bore cannula in the **2nd intercostal space** along the mid-clavicular line on the affected side is a **life-saving intervention** that must be performed immediately (Statement 2 is correct). - After needle decompression, **definitive chest tube insertion** in the **5th intercostal space** (mid-axillary line) should be performed (Statement 4 is correct). - Statement 3 is **incorrect** because tension pneumothorax is a **clinical diagnosis** requiring immediate treatment without delaying for imaging, which could be fatal. *2, 3 and 4* - This combination is incorrect because Statement 3 is wrong. - **Immediate chest X-ray should NOT be done** for suspected tension pneumothorax as it is a **clinical emergency** requiring immediate decompression without delay for imaging. - Statement 1 (the correct diagnosis) is also missing from this option. *1, 2 and 3* - This combination is incorrect because Statement 3 is wrong. - **Delaying treatment to obtain imaging** can be **fatal** due to cardiovascular collapse from mediastinal shift and impaired venous return. - Statement 4 (definitive chest tube insertion) is also missing from this option. *1, 3 and 4* - This combination is incorrect because Statement 3 is wrong. - The diagnosis is **clinical**, and treatment (needle decompression - Statement 2) should be initiated immediately to prevent hemodynamic compromise and death. - Statement 2 (immediate needle decompression) is also missing from this option.

Q: A patient with suspected head injury is brought to the emergency following road traffic accident. At the time of examination, patient is conscious with GCS 14/15 and stable vitals. There is bleeding from right ear and CSF leak from nose. Bruising is present behind the right ear. The most probable clinical diagnosis in this patient is

Fracture of the base of skull. ***Fracture of the base of skull*** - The combination of **bleeding from the ear (otorrhagia)**, **CSF leak from the nose (rhinorrhea)**, and **bruising behind the ear (Battle's sign)** are classic indicators of a **basilar skull fracture**. - These signs suggest a breach in the bone separating the brain from the external environment, often involving the **temporal bone** or the **anterior cranial fossa**. *Extradural haematoma* - This typically presents with a **lucid interval** followed by rapid neurological deterioration due to arterial bleeding, which is not suggested by the stable GCS of 14/15. - While it can be associated with skull fractures, the specific signs of **CSF leak** and **Battle's sign** point more directly to a basilar fracture. *Cerebral concussion* - A concussion involves a transient disturbance of brain function without macrostructural damage, characterized by symptoms like confusion, dizziness, and memory problems. - It does not involve **CSF leaks**, **otorrhagia**, or **Battle's sign**, which are indicative of a more severe structural injury. *Traumatic subarachnoid haemorrhage* - This involves bleeding into the **subarachnoid space**, typically causing a **sudden severe headache**, nuchal rigidity, and altered consciousness. - It does not directly explain **otorrhagia**, **rhinorrhea**, or **Battle's sign**, which are specific to a breach in the skull base.
