The adequacy of resident education in regional anesthesia is of national concern. A teaching model to improve resident training in regional anesthesia was instituted in the Anesthesiology Residency in 1996 at Duke University Health System. The key feature of the model was the use of a CA-3 resident in the preoperative area to perform regional anesthesia techniques. We assessed the success of the new model by comparing the data supplied by the Anesthesiology Residency to the Residency Review Committee for Anesthesiology for the training period July 1992–June 1995 (pre-model) and the training period July 1998–June 2001 (post-model). During the 3-yr training period, the pre-model CA-3 residents (n = 12) performed a cumulative total of 80 (58–105) peripheral nerve blocks (PNBs), 66 (59–74) spinal anesthetics, and 133 (127–142) epidural anesthetics. The CA-3 post-model residents (n = 10) performed 350 (237–408) PNBs, 107 (92–123) spinal anesthetics, and 233 (221–241) epidural anesthetics (P < 0.0001). All results are reported as median (interquartile range). We conclude that our new teaching model using our CA-3 residents as block residents in the preoperative area has increased their clinical exposure to PNBs.
