Residents attained acceptable failure rates for peripheral venous cannulation, orotracheal intubation, spinal, and epidural anesthesia after 79±47, 43±33, 36±20, and 21±11 procedures, respectively.

How many procedures are required for anesthesiology residents to attain acceptable failure rates in basic anesthetic procedures?
The cumulative sum method demonstrates wide interindividual variability in the number of procedures required for anesthesiology residents to achieve acceptable failure rates, suggesting performance should be tracked individually.
This study aimed at constructing learning curves for basic procedural skills in anesthesiology using the cumulative sum method. We recorded 1234 peripheral venous cannulations, 895 orotracheal intubations, 688 spinals, and 344 epidurals performed by residents during the first 10 mo of training. Learning curves for each procedure were constructed by using the cusum method. The number of procedures performed until attainment of acceptable failure rates was calculated. All residents mastered peripheral venous cannulation after 79 ± 47 procedures. Four of 7 residents attained acceptable failure rates at orotracheal intubation after 43 ± 33 proce- dures. Seven of 11 residents attained acceptable failure rates at spinal anesthesia after 36 ± 20 procedures. At epidural anesthesia, 5 of 11 residents attained acceptable failure rates after 21 ± 11 procedures. The cusum method is a useful tool for objectively measuring performance during the learning phase of basic procedures. The wide interindividual variability in the number of procedures required to be performed before attaining acceptable failure rates suggests that performance should be followed on an individual basis.
Getúlio Rodrigues de Oliveira Filho (Thu,) conducted a observational in Anesthesiology training. Basic anesthetic procedures (peripheral venous cannulation, orotracheal intubation, spinal, epidural) was evaluated on Number of procedures performed until attainment of acceptable failure rates. Residents attained acceptable failure rates for peripheral venous cannulation, orotracheal intubation, spinal, and epidural anesthesia after 79±47, 43±33, 36±20, and 21±11 procedures, respectively.
