SUMMARY
Objective. To analyze the mistakes while application of modern surgical magnet instruments for diagnosis and removal of ferromagnetic foreign bodies.Materials and methods. In accordance to the exploitation-clinical criteria, the material, delivered by usages of the magnet instruments (623 respondents), about results of its clinical usage in period from 2014 yr up to nowadays, was analyzed.Results. In total the mistakes while application of surgical magnet instruments may be divided on two groups: the clinical and exploitation-technical Most quantity of clinical mistakes are connected with application of such instruments without indications, basically in absence of ferromagnetic fractures inside the wounds channels and cavities. Other causes of the mistakes were following: failure to include physiologic peculiarities of the wound process course, such as formation of capsule over foreign bodies, characteristic of the wound channel, choice of inappropriate nomenclature specimen and failure to include the vessels and neural trunks projections, leading to development of complications (hemorrhage, neuralgia, paresis), formation of the contraperture incision and mechanical removal of the fracture. Sterilization in a dry-heat wardrobe and physical damage of instruments were taken into account and have been considered as an exploitation-technical mistake.Conclusion. In accordance to the results obtained, the conduction of educational trainings for usage of surgical magnet instruments, guaranteeing reduction of the various mistakes and complications quantity, leading to maximal effect of its application are recommended.
