What is the recommended cleaning agent for a laceration prior to suturing in a patient with no known allergies or sensitivities?

Laceration Cleaning Prior to Suturing

Use tap water or sterile saline for wound irrigation—both are equally effective and superior to antiseptic agents like povidone-iodine for cleaning lacerations before suturing. 1, 2

Recommended Irrigation Technique

Thorough irrigation is the most critical step in preventing wound infection, more important than the choice of solution itself. 1, 2

• Irrigate the wound until all visible debris and foreign matter are completely removed from the wound bed 1
• Use adequate irrigation pressure to effectively remove bacterial contamination—simple rinsing without pressure is insufficient 1
• Running tap water of drinking quality is safe and effective for wound cleaning 1, 3
• Sterile saline solution is an equally acceptable alternative to tap water 1, 2

What NOT to Use

Avoid antiseptic agents such as povidone-iodine for routine wound irrigation. 1

• Multiple studies demonstrate no benefit of povidone-iodine over simple irrigation with water or saline 1
• Infection rates are similar whether wounds are irrigated with tap water, boiled water, distilled water, or sterile saline 1
• Antiseptic solutions do not improve outcomes and may cause unnecessary tissue irritation 2

Special Circumstances Requiring Immediate Medical Evaluation

Certain contaminated wounds require more aggressive management beyond simple irrigation:

• Animal or human bite wounds must be evaluated in a medical facility as soon as possible, even after initial cleaning 1
• Wounds contaminated with human or animal saliva require professional assessment for antibiotic prophylaxis 1, 4
• Grossly contaminated wounds (soil, feces) may require surgical debridement in addition to irrigation and antibiotic coverage for anaerobes 4

Practical Implementation

• Clean the wound gently with soap and tap water once or twice daily after initial repair 3
• For contaminated wounds, antibiotic administration should begin within 3 hours of injury to minimize infection risk 4
• Thorough wound cleaning and debridement remain essential regardless of whether antibiotics are used 4

Common Pitfalls to Avoid

• Do not delay irrigation waiting for "sterile" solutions—tap water is immediately available and equally effective 1, 2
• Do not use antiseptics thinking they provide superior infection prevention—they do not 1
• Do not perform superficial rinsing—adequate pressure irrigation is necessary to remove bacterial contamination 1
