目的观察空气层流净化技术在新生儿重症监护室(NICU)的应用效果。方法通过空气采样检测和医院感染发生率的评价,对层流洁净技术用于新生儿重症监护室空气洁净效果和感染控制效果进行了观察。结果在连续2年运行中,对室内空气采样检测48次,合格率达到100%,室内物体表面共检测120次,卫生质量合格率为98.33%。在2年实际应用中,该新生儿重症监护室共入住2 728例患儿,发生医院感染44例(47例次),医院感染发生率为1.61%(例次感染率为1.72%)。结论应用空气层流净化技术能较好地保持NICU空气洁净度,有助于控制医院感染的发生。
Objective To observe the application effect of air laminar flow purification in neonatal intensive care unit (NICU). Methods By air sampling and hospital infection rate assessment, the laminar flow clean technology used in neonatal intensive care unit air cleanliness and infection control were observed. Results During the two years of continuous operation, the indoor air samples were detected 48 times, the pass rate was 100%, the surface of indoor objects were detected 120 times, the passing rate of hygiene quality was 98.33%. In 2 years of practical application, 2 728 children were admitted to the Neonatal Intensive Care Unit. There were 44 hospitalizations (nos. 47) and nosocomial infections (1.61%) (nosocomial infection rate was 1.72%). Conclusion The application of air laminar flow purification technology can better maintain the cleanliness of the NICU air, help to control the occurrence of nosocomial infections.
