Abstract:
Objective To explore the effect of different disinfectants on endoscopic disinfection and durability.Methods A total of 428 endoscopes were selected from the endoscopic center of our hospital from January 2016 to September 2016,and they were randomly divided into control group and observation group,each group in 214cases.The control group was treated with glutaraldehyde.The observation group used o-phthalaldehyde treatment disinfection.The sampling site was the endoscopic biopsy cavity surface,sterile syringe was used to extract 10ml containing neutralizer buffer,into the endoscopic biopsy to be tested,and then 15mL sterile test tube from the biopsy outlet collection,was checked within 2h.The sterilization pass rate was evaluated,the disinfectant disinfection endoscopic cavity and the number of surface colonies,disinfectant endoscopic durability in the two groups were compared.Results The disinfection rate was 89.25％ in the control group and 97.20％ in the observation group,the difference of the qualified rate of endoscopic disinfection between the two groups was statistically significant (x2 =10.69,P =0.001).The endoscopic cavity and the number of surface colonies of the observation group were lower than those of the control group (t =3.17,P =0.00;t =26.76,P =0.00).The numbers of disinfection per cycle and per day in the observation group were higher than those in the control group,the differences were statistically significant (t =94.44,P =0.00;t =23.94,P =0.00).Conclusion The use of o-phthalaldehyde for endoscopic disinfection is better,more durable,suitable for endoscopic room to promote the use.
