🫁 Thoracic Trauma High-Yield (NCLEX/ED)

I) 🌪️ Tension Pneumothorax (TPTX)

Key idea: Clinical dx—treat now, don’t wait for imaging. Patho: One-way valve → air traps in pleura → lung collapse + mediastinal shift → ↓venous return → obstructive shock; often from PPV with visceral injury. Meds: O₂ (often high-flow). Analgesia after stabilization. Team: MD does immediate needle/finger decompress → chest tube. RN preps gear, monitors vitals, reassesses; eFAST must not delay care. Cues (prio): 🟥 Hypotension/shock; 🟥 unilateral absent breath sounds; 🟧 severe tachypnea/air hunger; 🟧 tracheal deviation (late); 🟨 JVD; 🟨 cyanosis (late). RN actions: High-flow O₂; set up needle decompress (5th ICS, anterior to MAL) → mandatory tube. Reassess for recurrence. Quick: TPTX = air trapping + shock. Priority = decompression → tube. Avoid too-medial field placement.

II) 🩸 Massive Hemothorax (MHX)

Def: >1500 mL (or ≥⅓ blood volume) rapidly in chest. Patho: Blood in pleura → hypovolemic shock + lung compression → hypoxia. Tx fluids/blood: Large-bore IV/IO; crystalloids judiciously; start uncrossmatched/type-specific blood; consider autotransfusion. Team: MD inserts 28–32 Fr chest tube; considers thoracotomy. RN runs rapid infuser, assists tube, logs initial/ongoing output. Cues: 🟥 Shock; 🟥 initial tube output >1500 mL; 🟧 ↓/absent breath sounds; 🟧 dullness to percussion; 🟨 flat neck veins (often). RN actions: Two large IVs, rapid blood; assist tube (5th ICS, anterior to MAL); track loss—>200 mL/hr ×2–4 h = call for OR. Quick: Simultaneous volume + decompression; thresholds drive thoracotomy.

III) ❤️ Cardiac Tamponade (CT)

Patho: Blood in pericardium → restricted filling → ↓CO (obstructive shock). Definitive: Surgery (thoracotomy/sternotomy). Pericardiocentesis = bridge. FAST for dx. Cues: 🟥 Hypotension/poor response to fluids; 🟥 PEA arrest; 🟧 muffled heart sounds; 🟧 JVD (may be absent if hypovolemic); 🟨 Kussmaul’s sign. RN actions: Rapid IV fluids (temporize), continuous ECG, facilitate FAST, prep for OR. Quick: Think CT with PEA + shock in chest trauma.

IV) 🕳️ Open Pneumothorax (OPX) / “Sucking Chest Wound”

Patho: Large chest wall defect (~≥⅔ tracheal diameter) shunts air via wound → failed ventilation → hypoxia/hypercarbia. Team/Tx: Three-sided occlusive dressing (flutter valve) → chest tube remote from wound → surgical closure. Cues: 🟥 Hypoxia/hypercarbia; 🟧 audible sucking; 🟧 tachypnea/dyspnea; 🟨 ↓breath sounds. RN actions: Seal with sterile occlusive taped on 3 sides; watch for tension; place tube ASAP; secure airway if needed. Quick: Four-sided seal can create TPTX—avoid.

V) 🔑 Associated Injuries & Nursing Pearls

Airway obstruction: Look/listen/feel for stridor, voice change, neck crepitus. Suction blood/vomit; prep definitive airway; reduce posterior clavicle dislocation if obstructing. Flail chest + Pulmonary contusion: Contusion = common lethal chest injury. Give humidified O₂, ventilatory support PRN; judicious fluids; aggressive analgesia (IV/regional). Rib fractures: Pain → splinting → atelectasis/PNA. Treat pain (systemic or regional). Never tape/belt. Ribs 1–2 = high-force (check great vessels). Ribs 10–12 → suspect hepato-splenic injury. Older adults = higher mortality.

🚑 Trauma Shock & Thorax Emergencies

I) 🩸 Hemorrhagic (Hypovolemic) Shock

Patho: Acute blood loss ↓preload → ↓SV/CO; early tachycardia + vasoconstriction; prolonged hypoperfusion → lactic acidosis; lethal triad = 🧊 hypothermia + 🩸 coagulopathy + acidosis. Fluids/Blood:

• Warm crystalloids (1 L adult, 20 mL/kg peds) → avoid excess; consider permissive hypotension.
• MTP: pRBCs/Plasma/Plts (warm). O neg for childbearing-age females; AB plasma if unknown type.
• TXA: within 3 hrs (bolus then 8-hr infuse).
• Calcium: guide by ionized Ca²⁺. No vasopressors first-line. Team: MD leads definitive bleed control (OR/angio); RN gets 2 large-bore IVs/IO, gives warmed fluids/blood, binder/pressure, tracks response; Lab preps products. Priority cues: Marked tachy + hypotension + narrow PP + ↓LOC (Class IV); cool, pale skin; ↓UO. Elderly may lack tachy on β-blockers—SBP 100 can be shock. RN priorities: Categorize response (rapid/transient/non-), direct pressure/binder, target UO ≥0.5 mL/kg/hr, warm patient & fluids to 39 °C, trend lactate/base deficit. High-yield: Don’t rely on SBP alone—watch pulse pressure; stop bleeding + balanced resus; vasopressors 🚫 initial.

II) 🌪️ Tension Pneumothorax (Obstructive Shock)

Patho: One-way valve air → ↑pleural pressure → lung collapse + mediastinal shift → ↓venous return. Management: Immediate decompression (needle/finger) → chest tube. Don’t wait for X-ray. Cues: Hypotension/CO drop, severe dyspnea/air hunger, absent unilateral breath sounds, hyperresonance, tracheal shift (late), JVD. RN: Set up decompression ASAP, then assist sterile tube; monitor hemodynamic rebound. Pearl: Think triad—hypotension + unilateral absent sounds + hyperresonance.

III) ❤️ Cardiac Tamponade (Obstructive Shock)

Patho: Blood in pericardium → impaired filling → ↓CO. Often penetrating trauma. Management: Definitive surgery; pericardiocentesis = temporizing. FAST to detect fluid. Cues: Beck’s triad = hypotension, muffled heart sounds, JVD; tachy; poor response to fluids. RN: Prep for OR, support FAST, note non-response to resus; educate that surgery removes pericardial blood.

IV) 🧠 Neurogenic Shock (Distributive)

Patho: Cervical/upper thoracic SCI → loss of sympathetic tone → vasodilation & hypotension; may coexist with bleeding. Isolated head injury doesn’t cause shock unless brainstem involved. Distinct cues: Hypotension without tachycardia, warm/dry skin (no vasoconstriction), normal/wide PP. Management: Treat as hypovolemic first; if unresponsive to fluids, pursue neurogenic cause with advanced monitoring. Maintain full C-spine precautions. High-yield: Key differential = low BP + no tachy + warm skin.

🛑 Acute Airway & Ventilation Review

1) 🫁 Acute Airway Obstruction & Compromise

Patho: Fastest killer in trauma. Obstruction may be complete/partial/progressive. Common: tongue occluding hypopharynx with ↓LOC; also vomit, blood/secretions, teeth/FBs. ↓LOC → high aspiration risk → often needs definitive airway. RSI Meds:

• Etomidate 0.3 mg/kg → sedation w/ minimal BP/ICP effect; watch adrenal suppression & hypovolemia.
• Succinylcholine 1–2 mg/kg → rapid, brief paralysis; avoid in crush/burns/electrical/CKD/neuromuscular dz (↑K⁺). If fail intubation → BVM until recovery. Team Roles: 👨‍⚕️ Leader/Airway → assess & choose route/timing; plan for difficult airway. 👩‍⚕️ RN → suction ready, draw RSI meds, SpO₂/ETCO₂ monitoring, manual C-spine restriction. 🫁 RT → ventilator setup, capnography confirmation. 🧠 Consultants (neurosurg) for head-injured timing. Key Signs (🚨): No response/abnormal speech, stridor/gurgle/snore, absent breath sounds, agitation (hypoxia), tachypnea, cyanosis (late). RN Actions: Stimulate for verbal response; jaw-thrust/chin-lift; suction + log-roll lateral if vomit (maintain C-spine); pre-oxygenate 100% before/after attempts; OPA/NPA as bridge; high-flow O₂ ≥10 L/min; continuous SpO₂ + ETCO₂. Quick Hits:
• Priority #1 = airway & ventilation.
• Intubate if GCS ≤8, seizures, cannot maintain patency/oxygenation.
• Maintain C-spine throughout.
• Drug-assisted intubation needs rescue plan (surgical airway).
• Confirm ETT: bilateral breath sounds + exhaled CO₂ ✅.

2) 🗣️ Traumatic Airway Injuries (Laryngeal/Neck/Maxillofacial)

Patho: Neck hematoma displaces airway; larynx/trachea disruption → bleeding into tree; facial fx + swelling/teeth/secretions obstruct; bilateral mandibular fx = loss of support (esp. supine). Med pearls: Avoid nasal tubes if cribriform/basilar skull fx suspected. Team: 🔪 Surgeon → hemorrhage control & emergent airway (cric > trach in ED). 🖼️ Imaging (CT) after airway secure. 👩‍⚕️ RN/Airway → anticipate rapid loss; gentle ETT under direct vision if laryngeal injury. Red Flags (🚨): Laryngeal triad = hoarseness + subQ emphysema + palpable fracture; expanding neck hematoma/stridor; basilar skull signs (raccoon eyes, Battle’s, CSF leak) → no nasotracheal; refusing supine (mandible issues). RN Actions: Watch for swelling/SC air; be ready for surgical airway; avoid nasal routes with facial/skull fx. Quick Hits: Cric preferred; LEMON for difficulty; OTI is first-line when feasible.

3) 🌬️ Ventilatory Compromise

Patho: Ventilation failure from chest mechanics (rib fx/flail), CNS depression, or SCI.

• SCI: Above/below C3 → diaphragmatic-only breathing; rapid shallow ≠ effective → atelectasis → failure.
• Chest trauma: Pain → splinting → shallow breaths → hypoxemia. Sedation/Analgesia: Helps tolerance of assisted ventilation, but excess can abolish tone → airway loss ⚠️. Team: 👩‍⚕️ RN/Airway → assess symmetry, listen for ↓/absent sounds; beware PPV converting simple → tension pneumo or causing barotrauma. 🫁 RT → PPV, ETCO₂ monitoring. 👨‍⚕️ MD → ABGs; treat pain/CNS causes. Key Signs (🚨): Seesaw/abdominal breathing (SCI), asymmetrical rise (pneumo/flail), ↓/absent sounds, accessory muscle use. RN Actions: Check symmetric rise & bilateral air entry; 2-person BVM if needed; if poor sounds → alert for pneumo; continuous ETCO₂ for ventilation; protect head-injured from hypercarbia.
