[Aseptic non-touch technique in the operating room: keep it simple]. / Voor Toediening Gereed Maken op de operatiekamer: maak het niet te ingewikkeld.

OBJECTIVE: The Dutch national patient safety platform developed a protocol for the preparation of intravenous medication; the Aseptic Non-Touch Technique (ANTT). Use of ANTT on nursing wards has shown to reduce contamination of intravenous medication. Therefore it is dictated by the Dutch Healthcare Inspectorate that this technique has to be used at all departments in the hospital, including the operating theatre. However, because of the use of air treatment and operating theatre uniforms, the operating theatre cannot be compared with a nursing ward. In this study, the bacterial contamination of syringes prepared in the operating theatre by anesthesia nurses was determined. DESIGN: Simulation study METHOD: 45 anesthesia nurses prepared 1000 syringes of 10 ml bacterial culture medium, using their routine method of drawing up iv medication from vials. Turbidity in a syringe after culturing for 14 days at 30° C was used as evidence for bacterial contamination. Using questionnaires, nurses were interviewed in what degree their working method equals ANTT-protocol. We calculated how much extra time must be invested when using the strict ANTT-protocol in the operating theatre. RESULTS: Six syringes (0,6%) were contaminated. Normal dermal bacteria were identified in all syringes. The nurses who prepared the contaminated syringes worked similar manner as their colleagues. It takes an additional 54 minutes per day per operating theatre to work strictly using the ANTT technique. CONCLUSION: Contamination rates of aseptic preparations in the OR are very low, and are as low as ANTT preparations in a GMP-certified hospital pharmacy. Therefore it is legitimate to develop a modified ANTT-protocol for use in the operating theatre.
