  Aims. According to the nature of surgery operation, every surgery room has different quantity of bioaerosols. In this research, the effect of control systems on bioaerosols in surgery room was investigated.

  Methods. This is a descriptive-analytical research and studied samples which were seven operating rooms in one of the central hospitals of Tehran city were studied by filtration method with impactor. Sampling was accomplished before and after surgery. The samples immediately transported to laboratory and cultured in agar. After 48 hours of incubation, counting was done. The concentration of bioaerosols is calculated in term of cfu/m3. UVGI performed after finishing the surgery to starting the next, in spectrum of C with 253.7nm.

  Results. The concentration of bioaerosols before and after surgery was less than the standard in operating time. Also, urology surgery room in all of the conditions had the most quantity of colonies. There was a significant correlation between concentration of bioaerosols and UVGI (p<0.05).

  Conclusion. Increase the ACH during surgery cause to decrease of bioaerosols content after that.
