[Training curves for endosurgical interventions in neonates and infants]

[Learning curves in acquisition of experience for new technologies]

OBJECTIVE

Analysis of national and foreign trials investigating accumulation of experience in innovative technologies using the learning curves.

MATERIAL AND METHODS. S

Earching for Russian-language manuscripts was carried out within the references of the articles and in the ELIBRARY database. Foreign trials were selected from the PubMed database according to the keywords «learning curves in surgical practice». The discovered publications were studied for accordance with the objectives of this study.

RESULTS

Accumulation of experience in new technologies by using of learning curves is valuable to improve the training, determine duration of development of new technology and the factors affecting its characteristics.

CONCLUSION

The method is high-quality for comprehensive analysis of experience accumulation in new surgical technologies.

[Individual learning curves for microsurgical myocardial revascularization]

AIM

To create individual learning curves for microsurgical myocardial revascularization.

MATERIAL AND METHODS

It was analyzed duration of the individual stages of the first 100 CABG procedures which were performed using microsurgical technique and surgical microscope. Graphs reflecting correlation between duration of the individual surgical stages and their number were framed.

RESULTS

Improvement in distal anastomosis time, aortic cross-clamping time, cardiopulmonary bypass time and duration of surgery was observed with increased surgeon's experience.

CONCLUSION

Individual learning curves objectively characterize the learning process of microsurgical myocardial revascularization, allow to estimate the time need for improvement of cardiac surgeons' qualification and demonstrate dates for achieving average surgical quality during learning the technique.
