Pratique de l’anesthésie locorégionale périphérique par les internes en anesthésie-réanimation en région Poitou-Charentes

Abstract

ObjectivesThere are limited data on peripheral nerve block (PNB) practices by residents in France, especially with after introduction of ultrasound. A survey was conducted on PNB practices by French residents. Study designMulticenter prospective descriptive study. Patients and methodsAll residents completed a survey form after each PNB procedure. ResultsA total of 394 procedures performed by 21 residents in 4 hospitals were collected. The number of procedures and average volume of local anesthetics by type of block are: axillary block 245–25mL (62%), interscalene 29–21mL (7%), supraclavicular 1–25mL (0.3%), 2–25mL infraclavicular (0.5%), femoral 65–18mL (16.5%), sciatic 52–22mL (13%). Detection was done by ultrasound only for 365 (92.6%) procedures, and neurostimulation only for 23 (5.8%) procedures. The duration of procedure was less than 5min for 200 (50.7%) procedures and more than 15min for 16 (4%) procedures. A single puncture was required for 307 (78%) procedures. The initial block success was obtained in 369 (93%) procedures. High training level residents required less time (P<0.0001), less puncture (P<0.046) and less neurostimulation use (P<0.0001) than novices, without difference in success rate and the volume of local anesthetic required. ConclusionsThe majority of procedures performed by the residents are using ultrasound. The procedure is usually fast, requiring mainly a single puncture and has a high rate of success.
