RESUMEN
Objective: To investigate the effect of meticulous management on infection prevention and infection rate control in neonatal wards. Methods: 230 neonates admitted to Northwest Women and Children's Hospital from January 2022 to June 2022 were selected as the control group and 230 neonates admitted to Northwest Women and Children's Hospital in the same period were selected as the study group. The control group was given routine management, and the study group was given meticulous management. The sanitary conditions of the items in the wards, the rate of implementation of standard disinfection measures, neonatal infections, and the satisfaction of neonatal guardians were compared between the two groups. Results: The qualified rates of air, nipple, bottle, disinfectants, sterilized items, and hand hygiene of medical staff in the study group were higher than those in the control group (P < .05). The implementation rates of environmental management, equipment disinfection, personnel management, and skin management disinfection in the neonatal ward of the study group were higher than those of the control group (P < .05). The total infection rate of all newborns in the study group was lower than that of the control group (P < .05). Total satisfaction was higher in the study group than in the control group (P < .05). Conclusion: Meticulous management can play an effective role in the prevention and control of hospital-acquired infections in neonatal wards, and can effectively reduce the infection rate, which can be promoted and applied in clinical settings.
RESUMEN
Six organotin compounds (OTs) in core sediment collected from aquaculture water of Tong'an Bay, Xiamen were detected by GC-FPD. Based on 210Pb-dating data, the pollution history (from 1931 to 2007) of OTs in this area was reconstructed and their possible sources were also discussed. The results showed that the inputs of organotin compounds in this sea area began from 1950's (0-80 cm). The vertical concentrations of OTs ranged from 3.43-69.6 ng x g(-1) (dry weight), the mean value was 15.0 ng x g(-1). Butyltins concentrations ranged from 2.51-68. 8 ng x g(-1) and the average concentration was 14.6 ng x g(-1) which accounted for 97.4% of total OTs, while phenyltins just accounted for 2.58%. It is indicated that the aquaculture waters of Tong'an Bay were mainly contaminated by butyltin compounds, inferring that they may come from the early antifouling paint of ships. The distributions of OTs concentrations and compositions may be related to the complex influence of the hydrodynamic conditions, antifouling paint leakages from ships and marine structures, and aquaculture. Compared to the other harbors and bays, the magnitude of OTs pollution in the sediment from Tong'an Bay was at the low midpoint on a global scale. Moreover, the sedimentary history showed that, vertical OTs distributions were in good agreement with the usage history of organotin compounds as antifouling paints and the changes of the major function regionalization in the surrounding area.
