title: [Peripheral intravenous access in the operating room: characteristics and predictors of difficulty].
abstract: OBJECTIVE
  To investigate of predictor's factors of difficult venous access device in the operating room in elective surgery.
  
  
  METHODS
  In a prospective study in central operating room, were included all patients scheduled for a surgical or diagnostic intervention. Were excluded all patients admitted with functional venous access. For each, were recorded patient's demographic characteristics (age, gender, ASA class, BMI), history (chemotherapy, prolonged ICU stay, hospitalization for more than five days), data from the clinical examination (presence of skin lesions, arteriovenous fistulas, burns, neurological deficits) and the type of operator (trainee, nurse, resident, senior). The difficulty was judged on the number of attempts required for successful venous access. Puncture was considered easier for a number of attempts to one to two and difficult if the number of attempts was greater than two. Predictor's factors were identified after univariate and multivariate analysis.
  
  
  RESULTS
  During one year (March 2008 to February 2009), form returns in 1500 were met, 1325 were usable. Venous catheterization was successful in 50.9% at the first attempt in 24.2% of patients at the second attempt and after three attempts in 18% of patients. Only 6.8% of patients required more than three attempts. A central venous catheter was required in seven patients. In multivariate analysis, chemotherapy (OR=4.54, 95% CI [2.92 to 7.03]; P<0.001), a nurse in training (OR=2.27, 95% CI [1.40 to 3.63]; P=0.001), a resident in training (OR=2.14, 95% CI [1.29 to 3.58]; P=0.003) and the presence of burns (OR=3.59, 95% CI [2.44 to 5.27]; P<0.001) were identified as independent predictors of difficulty of peripheral venous access.
  
  
  CONCLUSIONS
  The optimization of venous access devices in the operating room through the search for predictors of difficulty.
