Abstract:
Objective:To discuss the bacteria detection before and after disinfection by using central negative pressure suction device terminal socket, reduce cross infection probability in hospitals and provide evidence for disinfection management specification. Methods:one hundred and thirty clinical central terminal devices with negative pressure were disinfected spirally with iodine swabs and among them, Department of respiration 48, Department of cerebral surgery 46, and Pediatrics 36, were sampled and sent to be cultured by clinical laboratory personnel before and after disinfection. The specimens were administered in a sterile blood AGAR plate culture medium, and the bacterial growth conditions were observed to detect the bacteria number as pollution standards. Results: The pollution rates of clinical equipment central pressure suction into the terminal socket after disinfection were: Department of respiration 8.33%; Department of cerebral surgery 6.52%; Pediatrics 5.56%, and the average pollution rate was 7.69%.The detected cases of pathogenic bacteria were gram-negative bacteria pollution, and contrasting the pollution rates before and after disinfection was statistically significant(x2=14.08, P<0.05). Conclusion: Using based iodine swabs disinfection central pressure suction mouth terminal socket can reduce the cross infection between the patients with risk and provide patients with safe medical environment.
