Should prophylactic antibiotics be given for nasal packing lasting ≤48 hours after epistaxis or sinus surgery, and what regimen is recommended if packing exceeds 48 hours or the patient has risk factors for infection?

Antibiotic Prophylaxis for Nasal Packing

Prophylactic antibiotics are not routinely necessary for nasal packing lasting ≤48 hours after epistaxis or sinus surgery, as clinically significant infections occur in less than 1% of cases regardless of antibiotic use. 1, 2

Evidence-Based Recommendation for Standard Cases

The American Academy of Otolaryngology-Head and Neck Surgery states that prophylactic antibiotics may be considered in high-risk patients, though evidence for routine use is limited. 1 This cautious position is strongly supported by recent meta-analysis showing:

• Clinically significant infection rate of only 0.8% (95% CI 0.2-1.9%) across all patients with anterior nasal packing, regardless of antibiotic use 2
• Number needed to treat of 571 to prevent one infection 2
• No documented infections in a 5-year retrospective study of 106 patients, whether or not they received antibiotics 3

The systematic review evidence is consistent: there is no statistical difference in infection rates between patients who receive prophylactic antibiotics versus those who do not. 4, 5

When to Consider Prophylactic Antibiotics

High-risk patients who may warrant prophylactic coverage include: 1

• Immunocompromised patients (cancer patients on chemotherapy, transplant recipients, HIV/AIDS with low CD4 counts) 6
• Patients with diabetes mellitus 6
• Patients with chronic obstructive pulmonary disease or congestive heart failure 6
• Patients on hemodialysis 6
• Patients with prior history of MRSA infection 6
• Patients with prosthetic heart valves or recent cardiac device placement 6

Antibiotic Regimen When Indicated

If prophylactic antibiotics are prescribed for high-risk patients, target Staphylococcus aureus coverage: 1

• First-line option: Anti-staphylococcal penicillin or first-generation cephalosporin (e.g., cephalexin 500mg PO BID)
• For MRSA colonization or high MRSA risk: Add vancomycin or use trimethoprim-sulfamethoxazole 6
• Duration: Continue only while packing is in place, discontinue within 24 hours after removal 6

The cardiac surgery guidelines emphasize that weight-based cephalosporin should be administered fewer than 60 minutes before incision and continued for 48 hours maximum after surgery, with all perioperative antimicrobials discontinued within 24 hours for clean procedures. 6

Critical Duration Thresholds

Non-resorbable nasal packing should remain in place for 48-72 hours, with an absolute maximum of 5 days. 1 The American Academy of Otolaryngology-Head and Neck Surgery explicitly advises against exceeding 5 days under any circumstances due to exponentially increasing complication risks. 1

• Evidence shows 85% nosebleed control with 1-3 days of packing, with no correlation between shorter duration and recurrence 1
• Prolonged packing beyond 5 days significantly increases risk of sinusitis, septal perforation, synechiae formation, and pressure necrosis 1

Resorbable vs Non-Resorbable Packing

For patients on anticoagulants or antiplatelet medications (including aspirin), use only resorbable packing materials (Nasopore, Surgicel, Floseal) to avoid trauma during removal. 6, 1

Resorbable packing does not require removal and dissolves with regular nasal saline spray use, eliminating the need for prophylactic antibiotics related to removal trauma. 1

Warning Signs Requiring Immediate Attention

Educate all patients with nasal packing to seek immediate medical attention for: 1

• Fever >101°F (possible sinusitis or systemic infection)
• Increasing pain or facial swelling (possible abscess or spreading infection)
• Vision changes (orbital complications)
• Shortness of breath or labored breathing (respiratory compromise)
• Active bleeding from nose or mouth despite packing

Common Pitfalls to Avoid

Do not prescribe prophylactic antibiotics reflexively for all nasal packing cases. The evidence clearly demonstrates this practice provides no benefit in standard-risk patients and exposes them to unnecessary risks including hypersensitivity reactions, renal failure, antimicrobial resistance, and Clostridioides difficile infection. 6, 2

Do not extend antibiotic prophylaxis beyond 24 hours after packing removal. Prolonged postoperative antimicrobials produce mixed results with low-quality evidence and significant potential for adverse effects. 6

Do not use non-resorbable packing in anticoagulated patients. This creates trauma during removal and theoretically increases infection risk, though the primary concern is rebleeding. 6, 1

Adjunctive Measures During Packing Period

All patients with nasal packing should: 1

• Apply nasal saline spray frequently throughout the day to keep packing moist and reduce crusting
• Use humidifiers to maintain nasal moisture
• Avoid activities that increase nasal blood flow (straining, heavy lifting, bending over)
• Sneeze with mouth open to avoid pressure changes in the nasal cavity

Topical Antibiotic Alternative

One audit study demonstrated that topical antibiotics (Naseptin) may be more appropriate, cheaper, and as effective as systemic antibiotics for anterior nasal packing, with a 58.2% reduction in systemic antibiotic prescribing and no increase in infective symptoms, rebleeding, or readmission rates. 7 However, this approach lacks validation in higher-quality studies and is not specifically endorsed by the American Academy of Otolaryngology-Head and Neck Surgery guidelines.
