title: Learning manual skills in spinal anesthesia and orotracheal intubation: is there any recommended number of cases for anesthesia residency training program?
abstract: Wide variability exists in the number of anesthetic procedures to which anesthesia residents are exposed during their training. The number of attempts at various procedures before a trainee becomes proficient at performing each anesthetic procedure is not known. To determine the learning process of 150 attempts of spinal anesthesia and 100 attempts of orotracheal intubation, the two most frequent anesthetic procedures, we evaluated 9 first-year anesthesia residents according to their rate of success or failure. The learning curves of both procedures revealed an initial rapid improvement of success during the first 20 attempts. Spinal anesthesia was more difficult to learn (p=0.0002) but the learning curves of spinal anesthesia and orotracheal intubation reached a nondifferent high success rate of 82 per cent and 88.9 per cent respectively (p=0.13). According to this study the institutional recommended number of cases for spinal anesthesia and orotracheal intubation were 112 and 27 cases respectively.
