Study Notes

Management of Mandibular Fractures

Temporary stabilization of anterior mandibular fractures can be achieved using stay or bridle wire around adjacent stable teeth. This helps reduce bleeding and supports the mandible.

Airway and Cervical Spine Control

Airway obstruction may arise from collapsed maxillary fractures, which can impinge on the soft palate and pharyngeal space.
Gentle repositioning of the maxilla is crucial to maintain airflow and control hemorrhage.
Endotracheal intubation is indicated in cases of severe damage, inability to maintain the airway, necessary ventilation, anticipated swelling, or complex injuries involving head, face, and chest.
Emergency surgical airway, including cricothyroidotomy or tracheostomy, is required when airway access cannot be secured by other means.
Needle cricothyroidotomy is a temporary procedure for oxygenation that lasts approximately 45 minutes, while surgical cricothyroidotomy involves making an incision for a tracheostomy tube.

Indications for Tracheostomy

Necessary for prolonged artificial ventilation due to head and chest injuries.
Facilitates general anesthesia during surgery for complex facial injuries.
Ensures safe postoperative recovery after extensive surgery.
Required following airway obstruction from laryngeal edema or injury to the base of the tongue.
Indicated after significant hemorrhage within the airway.

Breathing and Ventilation

After securing the airway, assess breathing efficiency through auscultation and chest X-rays.
Pneuomothorax (open, closed, or tension) and hemothorax indicate serious chest injuries compromising ventilation.
Thoracostomy drainage with a chest tube in the fourth intercostal space is the primary emergency treatment for pneumothorax and hemothorax.
Flail chest results from multiple rib fractures, creating a freely moving segment of the chest wall.
Diaphragmatic rupture can lead to herniation of abdominal contents, causing respiratory distress and hypotension.
Aspiration of foreign materials may require endoscopy for removal.

Circulation and Hemorrhage Control

Control of bleeding and resuscitation of intravascular volume are vital; most facial fractures do not result in life-threatening hemorrhage.
Significant blood loss is possible with panfacial fractures, especially in young children.
Signs of hypovolemia include tachycardia, with a heart rate over 100 beats per minute in adults.
Superselective embolization can be performed to locally stimulate clotting at bleeding sites.
Penetrating neck trauma requires airway protection and hemorrhage control due to potential internal bleeding.

Intravascular Volume Replacement

Establish adequate intravenous access using two large-bore catheters for fluid, blood, and plasma administration.
For crystalloid administration, use a 3:1 ratio with blood transfusion; an initial bolus for adults is about 2000 mL rapidly.
Continuous assessment of the patient's response guides further fluid transfusions.
In cases of surgical shock, group O negative blood may be used while awaiting type-specific blood.

Urine Output Monitoring

Urine output is a key indicator of cardiac output and should be monitored in trauma patients.
Norms for urine output: adults should have over 0.5 mL/kg/hour, children over 1 mL/kg/hour, and infants over 2 mL/kg/hour.

Neurological Assessment

Assess neurological status using the AVPU scale: Alert, Voice response, Pain response, Unresponsive.
Pupillary response evaluation assists in gauging the extent of head injuries; ipsilateral dilating pupil may indicate optic nerve damage or increased intracranial pressure.

Environmental Control

Fully exposing trauma patients is critical for thorough examination. Ensure a warm environment to prevent further injury from temperature exposure.
Employ logroll techniques for complete assessment, including the back.

Secondary Survey

Regular reassessment is essential during trauma management to monitor stability and detect early deterioration of the patient’s condition.
