ABSTRACT

INTRODUCTION:

The operating room is no longer the ideal place for early surgica training of cardiothoracic surgery residents, forcing the search for simulation-based learning options. The study's aim was the construction and surgicaltraining of coronary anastomosis in a portable, low-cost, homemade simulator.

METHODS:

This is an observational, analytical, and multicenter study. The simulator was built with common materials and was evaluated with the Objective Structured Assessment ofTechnical Skills (or OSATS) Modified. All junior and senior residents from nine national cardiothoracic surgery centers were considered for 90 days. Operative skill acquisition and time in the creation of side-to-side (S-T-S), end-to-side (E-T-S), and end-to-end (E-T-E) coronary anastomoses were evaluated. All sessions were recorded and evaluated by a single senior cardiothoracic surgeon during two time periods.

RESULTS:

One hundred and forty residents were assessed in 270 sessions. In junior residents, a significant improvement in final scores was identified in S-T-S (use of Castroviejo needle holder, needle angles, and needle transfer) (P<0.05). In seniors, a significant improvement was identified in S-T-S (graft orientation, appropriate spacing, use of forceps, angles, and needle transfer) anastomoses (P<0.05). A significant improvement in the final anastomosis time of senior residents over junior residents was identified in S-T-S (8.11 vs. 11.22 minutes), E-T-S (7.93 vs. 10.10 minutes), and E-T-E (6.56 vs. 9.68 minutes) (P=0.039).

CONCLUSION:

Our portable and low-cost coronary anastomosis simulator is effective in improving operative skills in cardiothoracic surgery residents; therefore, skills acquired through simulation-based training transfer have a positive impact on the surgical environment.
