Abstract:
Objective To compare the humidification efficacy of sterile water-filled cup and sterile water-filled wa-ter reservoir on infant incubators,as well as bacterial culture of incubators . Methods Ten infant incubators in a neonatal intensive care unit were randomly divided into observation group and control group,incubators in observa-tion group were humidified through sterile water in single used cups,in control group were through water in water reservoirs ,humidified water,air in incubators,and object surface were performed bacterial culture 24 hours after the change of humidified water. Results The humidity in both groups achieved the requirement of >50% ;the qualified rate of bacterial culture of humidified water in observation group was significantly higher than control group (91.00% vs 74.00% ,χ2= 10.009,P= 0.002);bacterial count in observation group was significantly lower than control group([26.85±16.67]CFU/mL vs [37.20±15.28]CFU/mL,t= 4.577,P<0.001).The qualified rate of bacterial culture of air and surface of incubators in observation group were both significantly higher than control group (94.00% vs 85.00% ;98.00% vs 68.00% ,both P<0.05).Conclusion Water-filled cups can achieve the air humidification efficacy on infant incubators,reduce the growth of bacteria,and is helpful for preventing the occur-rence of healthcare-associated infection.
