Ultrasonography and Italian anesthesiology: a national cross-sectional study

In recent years, ultrasound has seen a rapid development with numerous applications in anesthesia, intensive-care medicine, and pain medicine, increasing efficacy and safety of procedures. We investigated the prevalence of ultrasound use among Italian anesthetists.

A cross-sectional prevalence study was carried out on a sample of 735 anesthetists. The research was conducted during the ultrasound training in anesthesia and intensive care, in the Italian Associazione Anestesisti Rianimatori Ospedalieri - Emergenza Area Critica "SimuLearn^®" training centre (Bologna, Italy).

The overall prevalence of a dedicated ultrasound devices in the operating room was 70% [95% CI 66-73%], while 74% [95% CI 69-78%] in northern Italy, 61% [95% CI 52-68%] in southern Italy, and 70% [95% CI 63-77%] in central Italy, indicating a significant difference between the north and south of Italy. The prevalence of regular use of ultrasound was high for regional anesthesia and for central venous cannulation [82-95% CI 79-85%] and low for pain therapy procedures [7-95% CI 6-10%]. Multivariate logistic analysis showed that the presence of a dedicated ultrasound device and high expertise were factors associated with routine use of ultrasound for regional anesthesia in upper and lower limb blocks and in vascular access.

The appropriate training in the use of ultrasound in anesthesia, intensive-care medicine, and pain therapy should be implemented in south of Italy to make uniform the widespread of ultrasonography in anesthesia, in all Italian regions.
