What is the immediate management for a patient with lacerations, possible head injury, and potential substance withdrawal after a fall?

Immediate Management of Trauma Patient with Head Injury and Lacerations

This patient requires immediate emergency department evaluation with urgent non-contrast CT brain and cervical spine imaging, hemodynamic stabilization maintaining systolic blood pressure >110 mmHg, and wound management of facial lacerations, while monitoring for both traumatic brain injury complications and potential substance withdrawal syndrome. 1, 2

Initial Stabilization and Assessment

Airway and Hemodynamic Management

• Maintain systolic blood pressure >110 mmHg from first contact, as even a single episode of hypotension (SBP <90 mmHg) markedly worsens neurological outcome in head trauma 1, 2
• Use vasopressors (phenylephrine or norepinephrine) immediately if hypotension develops, rather than waiting for fluid resuscitation, as these interventions have delayed hemodynamic effects 2, 3
• Avoid hypotonic solutions such as Ringer's lactate in patients with head trauma 1

Urgent Imaging

• Obtain non-contrast CT of brain and cervical spine immediately without delay to identify intracranial hemorrhage, skull fractures, or cervical spine injury 1, 2
• The CT should use inframillimetric sections reconstructed with thickness >1mm, visualized with double fenestration (central nervous system and bone windows) 1, 2
• Temporal lobe contusions and lacerations are common in head trauma and frequently associated with expanding processes or subdural hematomas 4

Risk Factors Requiring CT Angiography

Given the temporal area laceration, assess for these high-risk features that would mandate CT angiography 1:

• Basal skull fractures
• Focal neurological deficits not explained by brain imaging
• Soft tissue lesions at the neck
• Any facial fractures (Lefort II or III type)

Wound Management

Facial Laceration Care

• Perform thorough examination and photographic documentation of temporal and nasal lacerations for reconstruction planning 5
• Assess for underlying cartilage or bone damage that requires reconstruction 5
• Nasal lacerations account for 7% of all facial lacerations and require careful evaluation of underlying structures 5
• Temporal lobe lesions from trauma frequently manifest with overlying soft tissue injury and may be associated with underlying intracranial pathology 4

Substance-Related Considerations

Zolpidem Withdrawal Risk

• 36% of intentional injury victims are drug dependent, and withdrawal syndromes in trauma patients confuse clinical management and can be lethal 6
• Withdrawal from sedative-hypnotics like zolpidem after chronic use can occur, though the patient's recent alcohol consumption complicates the clinical picture 6
• The mainstay of withdrawal therapy is supportive care and benzodiazepine therapy 6

Alcohol Intoxication and Withdrawal Monitoring

• Acute substance use at time of injury is present in 47% of TBI patients 7
• Monitor for alcohol withdrawal syndrome, which typically begins 6-24 hours after last drink and requires benzodiazepine prophylaxis 6
• Withdrawal syndromes must be promptly recognized and differentiated from traumatic or metabolic deterioration 6

Neurosurgical Intervention Criteria

Surgical evacuation is indicated for 2, 3:

• Extradural hematoma (symptomatic)
• Acute subdural hematoma with thickness >5mm and midline shift >5mm
• Brain contusions with mass effect
• Acute hydrocephalus requiring drainage
• Open or closed displaced skull fracture with brain compression

Critical Pitfalls to Avoid

• Never allow even brief episodes of hypotension while waiting for "adequate resuscitation" before starting vasopressors 3
• Never delay transfer to specialized neurosurgical center for "stabilization" at non-neurosurgical facility 2, 3
• Never miss underlying temporal lobe contusions or intracerebral hematomas, which are frequently associated with overlying subdural hematomas and can be erroneously diagnosed as brain edema alone 4
• Never assume substance use at time of injury indicates less severe injury—pre-injury substance abuse actually increases probability of more severe TBI (OR 4.05) 7

Monitoring Requirements

• Implement continuous neurological assessment for deterioration 2
• Monitor for post-traumatic seizures and implement prevention strategies 2, 3
• Screen for withdrawal symptoms from both zolpidem and alcohol using appropriate scales 6
• Maintain normothermia, as hyperthermia increases complications and unfavorable outcomes including death 2, 3
