Pulse lavage, also known as pulsatile lavage or high-pressure irrigation, is a medical procedure used primarily for wound debridement and cleansing. This technique employs a pressurized stream of saline or another irrigating solution to clean and remove debris, bacteria, and necrotic tissue from wounds, surgical sites, and other areas requiring meticulous cleaning. Pulse lavage has become a critical tool in both emergency and elective medical settings due to its efficacy and versatility.

The concept of using pressurized irrigation for medical purposes dates back several decades, evolving from simple syringe irrigation to sophisticated, mechanically-driven systems. Initially developed for orthopedic surgery to cleanse joints, the technique has since expanded to various medical disciplines, including wound care, burn treatment, and plastic surgery.

Pulse lavage systems typically consist of a hand-held device that delivers the irrigating solution in a pulsatile manner. The pressure and frequency of the pulses can be adjusted based on the clinical requirements. The high-pressure bursts effectively dislodge contaminants and devitalize tissue without causing significant damage to healthy tissue. The suction component of the device simultaneously removes the dislodged material and fluid, ensuring a clean and dry wound bed.

: The equipment and disposables used in pulse lavage can be expensive, which may limit its use in resource-constrained settings.

: High-pressure irrigation can generate aerosols, potentially spreading contaminants. Appropriate precautions, such as the use of personal protective equipment (PPE) and containment measures, are essential.
