What are the initial management steps for a patient with an open fracture in primary care, considering potential underlying medical conditions such as diabetes?

Open Fracture Management in Primary Care

In primary care, immediately administer IV antibiotics (cefazolin or clindamycin), apply a sterile dressing, splint the extremity, and arrange urgent transfer to an orthopedic trauma center within 24 hours for definitive surgical management. 1, 2

Immediate Antibiotic Administration (Within 1-3 Hours)

Early antibiotic delivery is the single most critical intervention to prevent deep infection and must not be delayed. 1, 2

• Administer cefazolin 2g IV (or clindamycin 900mg IV if penicillin-allergic) immediately for all open fractures 3, 1
• Add gram-negative coverage (piperacillin-tazobactam 3.375-4.5g IV) for severe injuries with extensive soft tissue damage or contamination (Gustilo-Anderson Type II-III fractures) 3, 1, 2
• Infection rates increase exponentially after 3 hours, making this the most time-sensitive intervention 1, 2
• Patients with diabetes mellitus have significantly higher infection risk and require meticulous adherence to early antibiotic protocols 3, 4

Initial Wound Management

Cover the wound with a sterile saline-moistened dressing—do not irrigate aggressively or apply antiseptics in the primary care setting. 3

• Gently irrigate visible gross contamination with normal saline only (no soap, antiseptics, or additives) 3, 1, 2
• Apply a sterile, saline-moistened gauze dressing to prevent desiccation 5
• Photograph the wound if possible, then cover and do not repeatedly unwrap for examination 6
• Avoid probing the wound or attempting debridement in primary care 7

Fracture Stabilization and Pain Management

Splint the extremity immediately in the position found to prevent further soft tissue injury and control pain. 1

• Immobilize the joints above and below the fracture 1
• Administer IV paracetamol (acetaminophen) 1g as first-line analgesia 1
• Avoid NSAIDs until renal function is confirmed, particularly in diabetic patients or those with potential hemorrhage 1
• Consider IV opioids (morphine 0.1mg/kg) for severe pain 1

Resuscitation and Assessment

Assess for hemorrhagic shock and initiate IV fluid resuscitation if hemodynamically unstable. 1

• Establish large-bore IV access (two lines if possible) 6
• Administer crystalloid fluids if signs of shock (tachycardia, hypotension, altered mental status) 1
• Check distal neurovascular status and document carefully before and after splinting 5
• Assess for compartment syndrome signs (pain out of proportion, pain with passive stretch, tense compartments) 6

Special Considerations for Diabetic Patients

Diabetic patients have substantially elevated infection risk and require aggressive early intervention. 3, 4

• Ensure antibiotic administration occurs within 1 hour if possible (not 3 hours) for diabetic patients 3, 4
• Check blood glucose and initiate glycemic control immediately 3
• Document peripheral vascular status, as diabetics with vascular disease have worse outcomes 4
• Lower threshold for adding gram-negative coverage even for less severe fractures 3

Urgent Referral and Transfer

Arrange immediate transfer to an orthopedic trauma center—surgical debridement should occur within 24 hours of injury. 3, 1, 2

• Contact the receiving orthopedic trauma service directly before transfer 6
• Document time of injury, antibiotic administration time, and neurovascular status 5
• Ensure patient remains NPO (nothing by mouth) for anticipated surgery 6
• Soft tissue coverage must occur within 7 days to minimize infection risk 3, 2

Critical Pitfalls to Avoid

• Never delay antibiotic administration to obtain cultures or await specialist consultation—every hour matters 1, 2
• Never use antiseptics, hydrogen peroxide, or soap solutions for wound irrigation—saline only 3, 1, 2
• Never attempt wound closure in primary care—this dramatically increases infection risk 7, 8
• Never prescribe NSAIDs without confirming renal function, especially in diabetic patients 1
• Never repeatedly unwrap the wound for examination—this increases contamination 6
• Never delay transfer while attempting definitive wound management—primary care role is stabilization and rapid referral 6
