RESUMO
Objective:To promote the reuse of recyclable medical wastes by analyzing the current status of the disposal and factors affecting recycling of medical wastes in medical institutions.Methods:On-site investigations were made on the collection and disposal of recyclable medical wastes at 20 tertiary hospitals in Liaoning Province in the timeframe from January 1 through December 31 of 2018, together with on-site interviews of 25 managers and 5 transfer personnels. Investigation results were then subject to descriptive analysis.Results:There were 18 tertiary hospitals that separately collect recyclable infusion bottles and infusion bags, and only one hospital collected empty bottles of penicillin and cephalosporin antibiotics. There was a linear relationship between the amount of recyclable medical wastes and the actual number of beds available( F=47.177, P=0.000). The amount of medical waste generated in general hospitals and that of recyclable medical waste generated were much higher than those of traditional Chinese medicine hospitals and specialized hospitals. The main factors on the recovery were poor and delayed command of relevant laws and decrees, and inadequate rules and regulations of the hospital, as well as lack of qualified recycling companies and poor compliance of transfer personnel. Conclusions:It is recommended that hospitals formulate and update rules and regulations, establish standardized recycling processes, and strengthen relevant staff training and supervision. The health commission is recommended to enhance communication with relevant authorities, for due appraisal of the qualifications of enterprises recovering recyclable medical wastes.
RESUMO
Objective:To establish a method for determining styrene monomer migration amount in ofloxacin and sodium chloride injection from three layer coextrusion infusion bags by GC-MS.Methods:The styrene monomer content in ofloxacin and sodium chlo-ride injection was detected by GC-MS in order to study the migration amount of styrene from the packaging bag ( three layer coextrusion infusion) of ofloxacin and sodium chloride injection .A DB-624123-1334 capilary column (30 m ×0.32 mm, 1.8 μm) was used, and the detection was carried out with programmed temperature and headspace sampling by the electron bombardment source (EI) in a selective ion monitoring (SIM) mode.Results:The linear concentration range of styrene was 46.96-543.60 ng· ml-1(r=0.9999), and the average recovery was 101.2％(RSD=3.1％, n=9).Conclusion:The method is simple, accurate and reproducible.It can be used for the compatibility testing between medicine and its package .
