Stable polytrauma definition (Multiple body regions injured (head + chest, abdomen + extremity, etc.) but **hemodynamically stable** after initial resuscitation — GCS ≥13 (or improving), normal perfusion, no ongoing uncontrolled hemorrhage; still requires trauma team, serial monitoring, and selective imaging (ATLS pediatric, WHO))
Monitoring & imaging strategy (Serial vitals q15 min initially · repeat GCS · **FAST** · CT per trauma team **pan-scan vs selective** based on mechanism and exam · avoid unnecessary radiation but do not miss occult injury — whole-body CT common in stable pediatric polytrauma at trauma centers (ATLS pediatric, Image Gently principles))
First-line therapy
Trauma team assessment + serial monitoring + selective imaging • procedure
Duration: ED / observation · Two IV lines · type & crossmatch · Foley if appropriate · **FAST** · labs (CBC, BMP, coagulation, lactate) · CT head/c-spine/chest/abdomen per findings and mechanism · admit trauma service/ICU observation (ATLS pediatric, AAP)
• **Monitoring:** continuous pulse oximetry, cardiac monitor, BP q15 min × 2 h then q30 min; serial GCS; urine output; temperature — detect delayed deterioration from occult bleeding (ATLS).
• **FAST:** eFAST at admission and repeat if clinical change — free fluid, pneumothorax, pericardial effusion; positive FAST with stability → CT and surgery consult (ATLS pediatric).
• **CT indications:** mechanism + exam-driven — CT head if GCS <15 or neuro signs (**head_trauma**); CT chest if abnormal exam (**chest_trauma**); CT abdomen if tenderness/FAST+ (**abdominal_trauma**); whole-body CT per trauma team protocol in stable multi-region injury.
• **Damage control principles (brief):** even in stable patients, prioritize life-saving procedures first; staged surgery if multiple surgical needs — damage control laparotomy if unstable later; planned reoperation (ATLS, pediatric trauma surgery).
• **Admission:** all stable polytrauma to trauma service — minimum 24 h observation; ICU if GCS concern, need for transfusion, or multi-system monitoring (ATLS, AAP).
Consultant coordination & staged definitive care • procedure
Duration: As indicated · Neurosurgery, general surgery, orthopedics, ICU — staged repair after life threats addressed; thromboprophylaxis per age/protocol; nutrition and DVT prophylaxis per institutional policy (ATLS, AAP)
• **Surgical prioritization:** 1) intracranial mass effect/decompressable head injury 2) ongoing torso hemorrhage 3) open fracture with vascular compromise 4) other orthopedic — coordinated at trauma center (ATLS).
• **Transfusion readiness:** type & crossmatch on arrival; reassess Hgb q6 h if solid-organ injury; transfuse for Hgb <7 or hemodynamic compromise (AAP, PALS).
• **Escalate to unstable variant** if BP drops, lactate rises, GCS declines, increasing transfusion requirement — repeat primary survey (ATLS).
• **Rehabilitation planning:** early PT/OT consult for polytrauma; psychosocial support; child-life services (AAP, WHO).
• Stable polytrauma: multiple regions injured but perfusing — still high-risk; trauma team, serial monitoring q15 min, FAST, mechanism-driven CT (ATLS pediatric, WHO).
• Imaging: selective vs pan-scan per trauma team; CT head/chest/abdomen based on exam and mechanism — see **head_trauma**, **chest_trauma**, **abdominal_trauma** (ATLS, Image Gently).
• Damage control (brief): address life threats first; staged surgery acceptable; abbreviated laparotomy if later instability (ATLS pediatric surgery).
• Admission minimum 24 h trauma service; ICU if GCS concern, transfusion, or multi-organ monitoring; escalate if deterioration (ATLS, AAP).
• Cross-links: **head_trauma**, **chest_trauma**, **abdominal_trauma**, **crush_injury**, **blast_injury** as mechanism-specific adjuncts.
