VECU DES PATIENTS LORS DE LA R?ALISATION DES BLOCS NERVEUX P?RIPH?RIQUES PATIENTS? EXPERIENCE DURING ULTRASOUND-GUIDED NERVE BLOCK.

Background: Nowadays, ultrasound-guided peripheral nerve blocks are recommended for peripheral surgeries allowing to increase efficiency and patient comfort. The aim of the study was to assess patient experience during the implementation of ultrasound-guided peripheral nerves blocks. Methods: A cohort study was conducted during seven months, from February to August 2015, in anesthesia department of P?rigueux?s hospital (France). The patient?s experience was assessed, especially pain and satisfaction. Correlation test was used for the statistic analysis. Results: For the study, 87 patients, 53 [18-87] yo, mostly women were included. Pain (with a median of 2 [0-4]) was high in 18.3% of cases. Other sensations like dysesthesia and pressure have been described. The satisfaction rate was high (88.5%), with a median of 9 [2-10]. Sedation has significantly decreased the pain intensity during the procedure. No determinant of satisfaction was found. However, practicians in the operating room and during the pre-anesthetic consultation appear to be a predictor of a subsequent block wish. Conclusion: These results allow us to conclude that a good support from the first contact of the practician with the patient improves patient experience. The interest of a pain killer before the completion of a peripheral nerve block could be inconstant.
