Comparison of a ferret model with an inanimate simulator for training novices in techniques for intubating neonates.

ABSTRACT

Simulators for neonatal intubation training have improved, prompting us to compare a state-of-the-art simulator with live ferrets for training novice family-medicine residents in this crucial skill. After a scripted didactic presentation, we used a crossover study design and randomly assigned residents to receive simulator or live ferret training, after which they repeated the procedure by using the opposite method. Participants were asked to report their level of confidence and competence before and after each training session and the usefulness of each training method. In addition, residents were videotaped performing the procedure and evaluated by using a modified global rating scale. The 2 methods did not differ in regard to self-reported confidence, competence, or usefulness of each training procedure. A majority of participants indicated that they preferred using the ferrets over the simulator, with realism cited most frequently as the reason for their choice. Videotape scores for time and motion and flow of the procedure were higher when the simulator was used, but higher for instrument handling when ferrets were intubated. Overall scores were higher for videotaped evaluations with the simulator compared with the ferrets. According to these findings, the simulator appears to provide adequate instruction for the initial training of novice learners in neonatal intubation techniques.
