A vacuum-assisted closure (VAC) device also known as negative pressure wound therapy (NPWT), is a medical treatment used to promote wound healing, it involves using a specialized device to apply negative pressure (suction) to a wound, which helps to accelerate the healing process.
Benefits :
Improved Healing: By removing excess fluid and reducing edema, the VAC device promotes faster wound healing and tissue repair.
Reduced Risk of Infection: The negative pressure helps to reduce bacterial load and create a more favorable environment for healing.
Enhanced Perfusion: The suction can improve blood flow to the wound area, aiding in the delivery of nutrients and oxygen essential for healing.
Granulation Tissue Formation: The therapy encourages the growth of new tissue (granulation tissue) which fills the wound and supports closure.
Overall, VAC therapy is a valuable tool in modern wound care, particularly for complex or difficult-to-heal wounds. If you or someone you know is considering or using this therapy, it's important to follow the guidance of healthcare professionals to maximize its effectiveness and manage any potential risks.
the study aim to evaluate patients , identify high risk ones , preparing to close wound of laparotomy with vaccum assisted device instead of primary closure with suturing till patient's general condition improve then delayed primary closure and comparing that to high risk patients who close wound primarily with suturing in terms of rate of burst abdomen …this is a randomized controlled trial
intraabdominal sepsis (wbc:>12000,HR>90,T>38,tachypnea and proven infection) Malnutrition including anaemia and hypoproteinemia Chronic diseases including diabetes and uremia Increased intra abdominal pressure including persistent coughing ,diffuse gaseous distention Smoking Previous abdominal surgery Old age Steroid use
Patients having elective surgery Absence of intra abdominal sepsis Negative exploration
