Introduction: In this article we analyze the use of the METI (Medical Education Technology Inc.) Human Patient Simulator (HPS) for the training of first-year anesthesiology residents in providing general inhalation anesthesia. The aim of this study was to compare simulation-based training on the METI HPS with traditional clinical-based training.

Methods: In this research were included 28 first-year anesthesiology residents which were randomly assigned to either traditional clinical-based (group A) or simulation-based (group B) training. The study consisted of two stages: the training stage (1) and the evaluation stage (2). On the 1^st stage residents from both groups were passing through clinical-based and simulation-plus-clinical-based courses, respectively. After a number of giving anesthesia the residents participated in, the competent mentors decided whether they were ready to step to the evaluation stage. On the 2^nd stage each of the participants had to provide general anesthesia on his/her own on the METI HPS. During all parts all participants were supervised by highly-qualified specialist. The results of the study were statistically processed by using a two-sample Student t-test.

Results: We found a statistically significant difference in the duration of the training stage between the two groups of participants. Residents from clinical-based group (group A) took part in 15,08 ± 1,83 anesthesia before they were allowed to proceed to the evaluation stage of the study. Residents from simulation-based group (group B) required only 7,27 ± 1,19 anesthesia for the same purpose.

In the evaluation stage there was a difference in average rating between the two groups. Group A scored 40,08 ± 2,57 out of 100 points, whereas group B got 70,55 ± 7,1 points, which is also a significant difference in terms of statistics (p<0,05).

Conclusions: The obtained data allow considering simulation training of residents with combined methods of anesthesia at the METI HPS. more effective.
