Abstract:
Objective To study the validity period of sterilized medical supplies packed by non-woven fabric or disposable paper-plastic packages and placed in different battle positions and storage conditions during long-distance navigation.Methods After autoclaving,the non-woven fabrics and paper-plastic packages stored in different battle positions on ships with different batches were tested for sterility,the validity period of the two packaging methods was determined,and the data were analysed.Results On the 150th day after sterilization,bacteria began to grow on the medical supplies packed by both packages in the machine room and engine room.On the 165th day after sterilization,bacteria began to grow on the non-woven packaging items in the dental room.On the 180th day after sterilization,bacteria began to grow on the paper plastic packaging items in the clinic(reception room).On the 180th day after sterilization,the medical supplies packed by both packages in the operation room had no bacteria growth.There was no significant difference in the validity period of sterilized medical supplies between disposable paper-plastic and non-woven packages in the same battle position(P>0.05).There was no significant difference in the validity period of sterilized medical supplies between medical clinic,dental room,and operation room(P>0.05),but there were significant differences between machine room,engine room,and operation room(P<0.05).Conclusion The term of validity of medical supplies packaged with disposable paper-plastic and non-woven fabric packages sterilized by autoclaving is both within 135 days,and there is no significant difference in the validity period date between the two packaging methods.
