    Abstract:
    INTRODUCTION: Recommendations on insertion and maintenance of central venous catheters (CVC) in intensive care unit (ICU) patients were updated in 2002. The aim of this study was to estimate their knowledge and/or application by physicians in French university hospital ICUs. METHODS: Two forms were sent to 124 professors of anaesthesia and intensive care encouraging them to participate to the survey. The first one was completed by the physician in charge of each unit and concerned the structure and activity of the unit in 2006. The second one was filled by each junior or senior physician working in the units and asked for experience, CVC insertion modalities and knowledge of CVC care protocols. RESULTS: Forty-one (75 %) university hospitals with at least one adult surgical ICU took part to the study. A questionnaire was filled by 124 senior (75 % of the staff) and 53 junior (43 % of the staff) physicians inserting an average of 10 CVC per month (range, 1-35). A written protocol for CVC insertion was known by 127 (72 %) of them. CVC insertion was done while wearing sterile gown (97 %), cap (100 %) and surgical mask (100 %) and using large sterile drapes (96 %). The antiseptic solution used for cutaneous antisepsis was povidone iodine in aqueous (36 %) or alcoholic solution (40 %), or an alcoholic solution of chlorhexidine (24 %) applied one (9 %), two (64 %) or three (27 %) times before insertion. A 4-times disinfection sequence (washing, rinsing, drying and disinfection) was performed by 161 (91 %) physicians. Ultrasound-guided insertion was realized by only eight (5 %) operators. CVCs were made of polyurethane (84 %), usually multi-lumens (>96 %) and rarely tunnelised (14 %). Only two physicians (1 %) sometimes use catheters coated with antibiotics or antiseptics. The site for catheter insertion was mostly the sub-clavian (47 %) or internal jugular vein (34 %), and rarely the femoral vein (20 %). CVCs were secured with a thread (99 %) and covered with a semi-permeable dressing (76 %). Concerning CVCs maintenance, 91 % of physicians acknowledged the existence of a written protocol in the unit. Dressings were changed every day (10 %), every two days (49 %), every three days (29 %) or every four days or more (12 %) by using the same antiseptic solution and semi-permeable transparent dressing in 78 % of cases. Venous lines changes were done during dressing maintenance (48 %), every day in case of administration of lipids (32 %) or just after administration of blood products via the catheter (32 %). Routine change of CVC was rarely recommended (11 %). CONCLUSION: The high number of answers allows setting of a precise state of CVCs insertion practices in adult surgical ICUs. Recommendations for central venous catheter insertion and maintenance are not still known and\or applied.
