ABSTRACT

BACKGROUND: There are many teaching methods for epidural anesthesia skill acquisition. Previous work suggests that there is no difference in skill acquisition whether novice learners engage in low-fidelity (LF) versus high-fidelity haptic simulation for epidural anesthesia. No study, however, has compared the effect of LF haptic simulation for epidural anesthesia versus mental imagery (MI) training in which no physical practice is attempted. We tested the hypothesis that MI training is superior to LF haptic simulation training for epidural anesthesia skill acquisition. METHODS: Twenty Post-Graduate Year 2 (PGY-2) anesthesiology residents were tested at the beginning of the training year. After a didactic lecture on epidural anesthesia, they were randomized into 2 groups. Group LF had LF simulation training for epidural anesthesia using a previously described banana simulation technique. Group MI had guided, scripted MI training in which they initially were oriented to the epidural kit components and epidural anesthesia was described stepwise in detail, followed by individual mental rehearsal; no physical practice was undertaken. Each resident then individually performed epidural anesthesia on a partial-human task trainer on 3 consecutive occasions under the direct observation of skilled evaluators who were blinded to group assignment. Technical achievement was assessed with the use of a modified validated skills checklist. Scores (0-21) and duration to task completion (minutes) were recorded. A linear mixed-effects model analysis was performed to determine the differences in scores and duration between groups and over time. RESULTS: There was no statistical difference between the 2 groups for scores and duration to task completion. Both groups showed similarly significant increases (P = 0.0015) in scores over time (estimated mean score [SE]: group MI, 15.9 [0.55] to 17.4 [0.55] to 18.6 [0.55]; group LF, 16.2 [0.55] to 17.7 [0.55] to 18.9 [0.55]). Time to complete the procedure decreased similarly and significantly (P = 0.032) for both groups after the first attempt (estimated mean time [SE]: group MI, 16.0 [1.04] minutes to 13.7 [1.04] minutes to 13.3 [1.04] minutes; group LF: 15.8 [1.04] minutes to 13.4 [1.04] minutes to 13.1 [1.04] minutes). CONCLUSIONS: MI is not different from LF simulation training for epidural anesthesia skill acquisition. Education in epidural anesthesia with structured didactics and continual MI training may suffice to prepare novice learners before an attempt on human subjects.

ABSTRACT

IMPLICATIONS: A single shot spinal anesthetic is not practical in a patient with a lumboperitoneal shunt. Neuraxial block and a blood patch (if necessary) may be performed in a patient on enoxaparin therapy if current guidelines for managing patients on anticoagulant therapy are followed.
