There are clear risks here, one technician moves to another patient because the team needs help, instruments are crossed between patients, there is clearly not surgeons for each of these patients. All of this can cause life threatening infections transferred from one patient to another. There is a real question of quality control, who does it. Are all technicians equal (some report that the technicians are hired and join the surgical teams that same week).
This would be outlawed in the US or most major Western countries.
