Because complications during central venous catheterization (CVC) are not rare and can be serious, the use of ultrasound (US) during CVC has been recommended to improve patient safety. The current investigation was designed to evaluate the frequency of, and factors influencing, US use for CVC. Toward that end, an electronic survey of all members of the Society of Cardiovascular Anesthesiologists was conducted. Univariate and multivariate logistic regressions were used to assess the association between the frequency of US use and hospital and physician factors.
Of the 4235 members, 1494 responded (response rate, 35.3%). Two thirds of the respondents never, or almost never, use US, whereas only 15% always, or almost always, use US. Thirty-three percent of the respondents never, or almost never, have US available, whereas 41% reported that in their hospital, US is always, or almost always, available. Availability of US equipment was strongly associated with US use for CVC (odds ratio = 18.9; P < 0.001). The most common reason cited for not using US was "no apparent need for the use of US" (46%). When US was selected, it was more commonly used for rescue or screening purposes rather than real-time guidance.
