|
|
Objectives: This study is to provide scientific basis of shelf life and to reestablish shelf life in hospital environment by investigating validity periods of variety packaging materials.
Methods: This study used 3 kinds of packaging materials and storage 600 steam sterilization samples in Neonate intensive care unit on open shelf. At the end of 20 days and 3 months, 100 packages were randomly extracted for each packaging material and contamination was identified through microbial culture testing. The temperature and humidity were measured by automatic control system to investigate the storage environment during the study period.
Results: The average temperature was 24.94±1.04°C and mean relative humidity was 46.19±12.27%. One sample packed by crepe paper was contaminated over 3 months. None of the samples were contaminated packed by muslin and Non-Woven fabric.
Conclusion: This study was to promote expense and management efficiency by reestablishing shelf life in hospital environment. On these results, Except for crepe paper, muslin and Non-Woven fabric were maintained sterile over 3 months. Existing shelf life can be extended from 20 day to 3 months.
