Comparison of the Breach of the Aseptic Barrier After Surgical Handwashing: Drying With One or Two Surgical Towels

What this Trial Is About

Researchers are evaluating whether drying hands after surgical washing with two sterile towels reduces contamination compared to using only one towel among healthcare workers and surgical residents. This randomized, multicenter trial involves up to 72 participants from three hospitals in Bogotá, Colombia. The study uses a fluorescent cream to simulate bacteria and monitors contamination by checking for fluorescence on the skin after drying. Participants will perform conventional surgical scrubbing and then dry their hands with either one or two surgical towels, as assigned randomly. They will be shown a video on the drying technique and given one minute to dry their hands. A research assistant, unaware of the study goals, will assess contamination using a UV light lamp to detect fluorescent cream presence on the upper limbs. During the study, participants will remove accessories and roll up sleeves above the elbows. Data will be securely collected and de-identified for analysis. The main measurement is the presence or absence of contamination within three minutes after handwashing and drying. Statistical analysis will compare contamination rates between groups and consider other influencing factors. Results will be published in a peer-reviewed journal.
