The surgical treatment protocols recommended by professional communities today do not include indicators of the duration of the stages of the operation and inter-stage intervals. However, they are very necessary to improve personnel coordination and reduce the number of errors, thereby increasing the safety and effectiveness of surgical treatment.

Purpose – compare the duration of operations, surgical stages and inter-stage intervals performed by the same surgeon (and different ones) during homogeneous and different operations to determine possible standards and estimates of time losses for preparatory stages (inter-stage intervals).

The duration of cardiac surgery stages was monitored during monitoring and computer observation of 3832 patients. It was established that the indicators of the average duration of the stages can be used as guidelines when drawing up protocols of operations, provided that the operation was successful and the perioperative period passed without complications. It is noted that protocols for the treatment of diseases of the cardiovascular system, both surgical and teratopoietic, should take into account the time spent on the stages and procedures of treatment, including the loss of time between stages.

The results of the studies can be used to improve the assessment of quality and prognostic capabilities both for individual stages and for operations in general.
