Guidelines for Saline Irrigation in Wound Care

General Principles for Wound Irrigation

• Superficial wounds and abrasions should be thoroughly irrigated until there is no obvious debris or foreign matter in the wound 4
• Running tap water or sterile saline solutions are preferred over antiseptic agents like povidone-iodine for most wound irrigation 4, 5
• Clean superficial wounds should be covered with an occlusive dressing after irrigation to promote healing 4

Specific Irrigation Recommendations by Wound Type

Chemical Eye Injuries

• Use continuous, large volumes of clean water for irrigation of chemical eye injuries 1, 2, 3
• Continue irrigation until a healthcare professional evaluates the injury and determines that pH has returned to normal 2
• Animal studies show water is more effective than saline in reducing high alkaline pH in corneal injuries 1, 2
• Contact the local poison center to assist with identification of any chemical involved in ocular injury 2

Traumatic Wounds

• Thorough irrigation with running tap water or sterile saline is recommended for traumatic wounds 4

Surgical Wounds

• There is insufficient evidence to determine the definitive role of saline irrigation of incisional wounds before closure to prevent surgical site infection (Grade of Recommendation 2B) 6
• Pulse pressure irrigation with saline may be more effective than standard irrigation in reducing surgical site infections 6

Special Considerations

• Wounds contaminated with human or animal saliva should be evaluated in a medical facility as soon as possible, regardless of irrigation method 4
• If a person with a superficial wound develops redness, swelling, foul-smelling drainage, increased pain, or fever, remove the dressing, inspect the wound, and seek medical care 4

Common Pitfalls to Avoid

• Using antiseptic solutions like povidone-iodine for routine wound irrigation when tap water or saline would suffice 4, 5
• Stopping irrigation too early for chemical eye injuries before pH has normalized 2, 3
• Assuming all wounds require the same irrigation approach regardless of contamination level or location 4, 6
