Abstract

Fatigue is a temporary decrease in the efficiency of an organism or organ due to intensive or long-term work, which is manifested in a decrease in quantitative and qualitative indicators of work and deterioration of coordination of work functions. Groups of simultaneous operations (411 patients) and group of single operations (746 patients) were formed. In both groups these changes were insignificant in most cases (except for marginal values in obese patients III, there were 6 such cases in the first group and8 inthe second), corrections of the port administration scheme were performed when performing vertical gastrectomy in both groups. After the calculation, the average deviations were1.2 cmin the first group and1.4 cmin the second. When using a laparoscope with a viewing angle of 0 o, the approach distance of the laparoscope with its own method of access on average during normal surgery is (6.92 ± 0.306) cm and is slightly smaller than standard methods, the average value of the studied parameter in the control group is - (6.98 ± 0.258) cm (p <0.001). Visualisation during simultaneous laparoscopic operations using our developed technique was on the level with single laparoscopic operation, performed classically.

Highlights

The most accessible, and the most common, methods of studying the efficiency of people in the workplace are test methods
It is important that sufficient visualization is ensured while maintaining the possibility of comfortable operation and effective manipulation. Laparoscopic operations by their nature require a high level of visualization, and if this visualization is not provided by the laparoscope, it is necessary to change its position, angle of view, distance to the target organ
To evaluate the methods according to the established criteria, we took into account the frequency of needs to change the area of operational influence, the position of the laparoscope, the frequency of the fencing effect

Summary

Introduction

The most accessible, and the most common, methods of studying the efficiency of people in the workplace are test methods. When studying the efficiency of a group of workers according to the above formula, the rate of change for each function at each time of observation of Ki is calculated.
