🫁 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.
