Pulseless pink hand
Urgent reduction and pinning (Class I)
Post-fixation observation with frequent checks
Procedural sedation
Sedation for reduction or splinting if needed
Ketamine
1-2 mg/kg IV
Repeat 0.5 mg/kg IV as needed
Monitor for laryngospasm and emesis
Nitrous oxide
50-70% inhaled if available
Suitable for brief manipulations
Fasting and risk assessment
Emergency nature overrides strict NPO in limb threat (ACEP Level C)
Antibiotics and tetanus for open fracture
Open fracture bundle
Antibiotics
Cefazolin
30 mg/kg IV
Maximum 2000 mg per dose
Repeat every 8 hours per local protocol
If gross contamination
Add gentamicin per local protocol
Weight-based dosing and renal adjustment
Tetanus prophylaxis
Vaccine update per immunization history
Tetanus immune globulin if not immunized and dirty wound
Irrigation and sterile dressing
Avoid aggressive probing in ED
Monitoring and reassessment
Reassessment schedule
Neurovascular checks
Before and after splint
Before and after reduction
After analgesia or sedation
Compartment syndrome surveillance
Increasing pain despite immobilization
Pain with passive stretch progression
Evidence and recommendation tags
Consensus recommendations
Early neurovascular assessment and documentation (ACEP Level C)
Emergent orthopaedics for pulseless pale hand (Class I)
Avoid excessive elbow flexion in vascular concern (ACEP Level C)
Special Populations
Pregnancy
Pregnancy considerations
Pediatric supracondylar fracture rare in pregnancy context
Consider pregnancy status in adolescent patients
Imaging
Plain radiographs acceptable with shielding when feasible
Analgesia
Prefer acetaminophen first line
NSAID avoidance in later pregnancy if applicable
Geriatric
Geriatric considerations
Pediatric supracondylar fracture not a geriatric diagnosis
If adult distal humerus fracture, management differs
Alternative adult patterns
Osteoporotic distal humerus fractures
Pediatrics
Pediatric specifics
Weight-based dosing for analgesia and sedation
Use kg-based calculations and maximum dose caps
Non-accidental trauma screen in atypical history
Inconsistent mechanism or delayed presentation
Immobilization tolerance
Extra padding for swelling
Cast and splint pressure point checks
Follow-up timing
Early ortho follow-up due to displacement risk in swelling phase
Background
Epidemiology
Population patterns
Common pediatric elbow fracture type
Peak school-age children
Extension-type majority
Fall on outstretched hand mechanism
Associated neurovascular injury risk
Higher in displaced fractures
Pathophysiology
Injury mechanics
Distal humerus supracondylar region failure
Thin cortical bone and olecranon fossa area
Extension-type
Distal fragment displaced posteriorly
Flexion-type
Distal fragment displaced anteriorly
Neurovascular structures at risk
Brachial artery in antecubital fossa
Median nerve and AIN
Radial nerve
Ulnar nerve in flexion-type and medial pinning
Therapeutic Considerations
Management goals
Restore alignment
Prevent malunion and cubitus varus
Protect perfusion and nerve function
Time-sensitive limb salvage in ischemia
Minimize swelling complications
Avoid excessive flexion in splints and casts
Operative fixation rationale
Percutaneous pinning provides stable alignment
Reduces risk of late displacement versus immobilization alone in displaced types
Patient Discharge Instructions
copy discharge instructions
Discharge instructions
Splint care
Keep splint clean and dry
Do not insert objects inside splint
Elevation and swelling control
Keep hand elevated above heart level for 48 hours
Ice over splint intermittently if comfortable
Pain control
Acetaminophen and ibuprofen per weight-based plan
Avoid duplicate acetaminophen in combination products
Activity limits
No sports climbing or rough play until cleared
Follow-up
Orthopaedics appointment within 5-7 days or sooner as directed
Return to ED now if
Increasing pain not controlled by medication
Fingers numb tingling or weak
Fingers turning pale blue or cold
Increasing swelling with tight splint sensation
Inability to move fingers
Fever or drainage from wound if open injury
