ABSTRACT
Objective To investigate the bacteriostatic effect of on the surface of bacter contamination survey sterile protective during microscope operating, to provide basis for the implementation of the preventive hospital infection. Methods Routine surgical care was used as the control group(100 cases). The intervention group(100 cases) was carried out during neurosurgery performed between February and December 2016. Instrument nurses wiped the microscope aseptically with the blood by using new sterile injection water wipes with non blood mucus. The Results of bacterial monitoring and the incidence of nosocomial infection were compared before and after the intervention. Results There was no significant difference between two groups during the former four hours of the neurosurgery(P>0.05). Respectively after using microscope 5 h and 6 h, the qualified rate of bacteria monitoring on sterile protective sleeve surface were increased to 97/100(no wipe 71/100)and 95/100(no wipe 51/100)in intervention group,the difference were statistically significant(χ2=25.15,49.11,P<0.01). Conclusions The bacteriostatic effect of cleaning blood stain on the surface of sterile protective during microscope operating is significant.The intervention is worthy of promotion in neurosurgery.
ABSTRACT
Objective To evaluate the biological effect of a kind of protective cover against inhalation of depleted uranium (DU) dust particles. Methods At 1 and 3 d after inhalation of DU dust particles, uranium concentrations in the blood, lung, bronchia, kidney, and liver of the rats in the protected group and non protected group were measured and the efficiency of protection was calculated. Results Uranium levels in all tissues and fluids of the rats in the protected group decreased significantly to 71.2%-96.1% as compared with those in non protected group. Conclusion The protective cover is effective to reduce the harm due to inhalation of DU dust particles.
