Paraffin oil to protect skin from tourniquet damage during upper limb surgery

Paraffin Oil for Preventing Tourniquet-Related Skin Lesions in Upper Extremity Surgery (PARA-TOUR RCT)

Not applicable Interventional Istanbul Medipol University Hospital · NCT07523958

This trial will try applying topical paraffin oil to the skin of adults having elective upper extremity surgery to see if it prevents tourniquet-related redness, blisters, or abrasions.

What this trial studies

This is a single-center, prospective, two-arm randomized controlled trial comparing topical paraffin oil plus routine protective dressing versus routine protective dressing alone in adults undergoing elective upper extremity surgery with a pneumatic tourniquet. Eligible patients are randomized using a computer-generated block method and the paraffin oil is applied to the skin area where the tourniquet will be placed before surgery. Skin integrity is assessed immediately after tourniquet removal and again at 30 and 60 minutes postoperatively using standardized skin assessment criteria. The trial aims to determine whether a simple, low-cost topical barrier can reduce short-term tourniquet-related skin complications.

Who should consider this trial

Good fit: Adults (age ≥18) scheduled for elective upper extremity surgery with pneumatic tourniquet use, ASA I–III, BMI <30 kg/m², who can give informed consent are ideal candidates.

Not a fit: Patients with preexisting dermatologic disease at the tourniquet site, known allergy to paraffin oil, obesity (BMI ≥30), emergency surgery, or expected ICU transfer postoperatively are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, this could provide a simple, low-cost way to reduce tourniquet-related skin injuries during arm and hand surgeries.

How similar studies have performed: While barrier moisturizers and protective dressings have shown benefit in reducing friction-related skin injuries in other settings, using paraffin oil specifically to prevent tourniquet-related lesions is novel and not widely studied.
