ABSTRACT
Objective In order to discuss the evaluation of generalized sterization for dental handpieces. Methods The generalized sterization for dental handpieces were used inclued collection dental handpieces, automatically cleaned, dried and distilled with oil, packed with paper or plastics and sterized with pulse-vuccum. Results All the indexes were fitted to the standard after the generalized sterization among the dental handpieces. The valid rate was 100%. Conclusions Generalized sterization for dental handpieces are effective measures to guarantee the clinical sterization quality.
ABSTRACT
Objective To analyze the value of color Doppler ultrasound in the diagnosis of lower extremity arterial disease in patients with type 2 diabetes mellitus.Methods A total of 800 patients with type 2 diabetes mellitus underwent color Doppler ultrasonography to examine anterior tibial artery (ATA),dorsalis pedis artery (DPA) and posterior tibial artery (PTA).Ultrasonic findings including vascular diameter,stenosis ratio and hemodynamics of lower extremity arterial disease were analyzed retrospectively.Results ATA and DPA had more plaques and stenosis than PTA.There was no statistical difference of vascular diameter,stenosis ratio and hemodynamics between left and right lower extremity artery in patients with type 2 diabetes mellitus including diabetic foot.Conclusion Color Doppler ultrasound is a useful method in the diagnosis of lower extremity arterial disease in patients with type 2 diabetes mellitus,providing information of stenosis ratio and hemodynamics of lower extremity artery,so as contributing to the clinical therapy of this disease.
ABSTRACT
OBJECTIVE To investigate the clinical degree of satisfaction to sterilizing-supplying center,and to consummate the development of the transition of its decentralized administration to centralized pattern.METHODS We designated the questionnaire of degree of satisfaction(DOS) and carried out the investigation.RESULTS The initiated DOS was 90.6%,the DOS in mid-stage(2006-2007) was 97.3%,and the DOS in the latest stage(2008) was 99.1%.CONCLUSIONS Centralized administration is effective pattern for the development of sterilizing-supplying center and important to ensure the quality of sterile materials and service for clinical medicine.
ABSTRACT
OBJECTIVE To reinforce the administration in the management of reusable medical appliances,and to ensure the quality of sterile.METHODS Every step of the integral sterilization were monitored.RESULTS The quality of every link in the course and the end quality of the reusable medical appliances were assured.All the pass-rates of routine examination and sample examination of our hospital and CDC in Zhuhai were 100%.CONCLUSIONS The process of integral sterilization in the management of reusable medical appliances can ensure the quality of sterile materials,and can prevent the nosocomial infections and guarantee the safety of patients.
