Brief Summary

The purpose of this study was to compare microbial contamination on the surface of reusable stasis after indefinite use, 2 weeks and 4 weeks. We investigated how the site - the operating theater and the emergency department, as well as the time of use - affects the number of organisms.

Conditions

Microbial Colonization; Infection, Bacterial; HAI; Nurse's Role; Vascular Access Device Complications; Vascular Access Complication; CRBSI - Catheter Related Bloodstream Infection; Catheter Infection; Device Colonisation

Keywords

Tourniquet; Cross Infection; Vascular Access Devices; Infection Control

Outcome Measures

Primary Outcomes (2)

• Standard Deviation and median of colony forming units (CFU/cm2) in the emergency department

  After 24h incubation at 37 deg C, we evaluated the number of bacterial colony-forming colonies on leaf and quality plates. The average number of CFU/cm2 in all stages of the study for the emergency department is 19,110, 34 CFU/cm2. For the MCC substrate for the emergency department medium 227.65; standard deviation 102.75 CFU/cm2. For the King B substrate for the emergency department medium 241.71, standard deviation 115.15 18 CFU/cm2. There is no statistically significant difference for OD versus CFU/cm2 during the second and third intake. There were no bacterial growth was obtained on the ECC plate.

• Standard Deviation and median of colony forming units (CFU/cm2) in the operating theatre

  After 24h incubation at 37 deg C, we evaluated the number of bacterial colony-forming colonies on leaf and quality plates. The average number of CFU/cm2 in all stages of the study for the operating theatre was 88.27 CFU/cm2. For the MCC substrate for the operating theatre medium 14.18 standard deviation 24.06 CFU/cm2. For the King B substrate for the operating theatre medium 33.07 standard deviation 65.18 CFU/cm2.There is no statistically significant difference for OD versus CFU/cm2 during the second and third intake. There were no bacterial growth was obtained on the ECC plate.
