On February 15, the world celebrates the International Day of the Operating Nurse. These people prepare operating rooms for work, are responsible for the sterility of all instruments, their timely delivery and accompanying the operating surgeon during the entire operation. The first surgical department of the Multidisciplinary Medical Center of ONMedU is the place where urgent, emergency care and planned surgical interventions with subsequent round-the-clock monitoring of patients have been provided for many decades in a row. And this whole process is impossible without the participation of medical operating nurses.
