The use of ultrasound in France: a point of view from experienced regional anesthesiologists.

A cross-sectional survey study on French practice in ultrasound-guided regional anesthesia was carried out. A questionnaire (demographic data, assessment of the likely benefits of ultrasonography, and its use in daily practice: blocks and hygiene) was emailed to all members of the French-speaking association of anesthesiologists involved in regional anesthesia. The questionnaire was filled out and returned by 634 experienced anesthesiologists. An ultrasound machine was available in 94% of cases. Ultrasound-guided regional anesthesia has become the gold standard technique for three-quarters of responders. Axillary, interscalene, popliteal sciatic and femoral nerve blocks were performed by more than 90% of responders, most frequently under ultrasound supervision. Conversely, ultrasound guidance was rarely used for spinal or deep nerve blocks. A specific sterile sheath was used in only 43% of cases. The present study confirms that ultrasound guidance has gained in popularity for many superficial, but not deep, regional anesthesia procedures in France.
