目的探讨洁净手术室随使用时间的延长其洁净度变化的特征,建立可靠的质量保证体系.方法选取我院一间Ⅲ级洁净手术室在使用1年半和2年半后,用激光尘埃粒子计数器检测清洁30 min和45 min后静态尘埃微粒数.结果洁净手术室使用1年半时清洁后自净30 min 0.5 μm微粒未超过医院洁净室洁净度指标要求<350个/L的标准,待使用2年半时清洁后自净30min 0.5 μm微粒超过了<350个/L的标准,与使用1年半时相比差异显著;并且洁净手术室使用2年半后直径较大的1 μm和2 μm微粒均较使用1年半时显著增多;清洁45 min后使用2年半的洁净手术室0.5 μm微粒亦可达到医院洁净室洁净度标准;虽然使用2年半时0.5,1,2 μm微粒的数量仍均高于使用1年半时同等状况下的测量值,但无显著差异.结论随着洁净手术室使用时间的延长其洁净度下降,室内空气尘埃粒子数增多,但延长清洁时间仍可保证洁净度;建立可靠的质量保证体系后,2年半后的静态尘埃微粒数仍在正常范围内.

Objective To explore the features of the cleanliness change with time during the use of laminar operating rooms in order to establish reliable quality assurance system. Methods Two grade 3 lami-nar operation rooms were chosen to be tested after one and a half year and two and a half years, laser counter was used to detect the static particulates after cleaning for 30 minutes and 45 minutes. Results After the laminar operation room was used for one and a half years the amount of 0.5 μm particulates in indoor air was less than 350 per liter, and after two and a half years it's above 350 per liter after cleaning for 30 minutes, an obvious difference than the previous one. The anaount of 1 μm and 2 pan particulates also increase obviously, but ff cleaning for 45 minutes the amount of 0.5 μm particulates in indoor air will fulfill the qualification. Al-though the amount of 0.5 μm, 1 pan and 2 μm particulates after 2 years using was higher than the one and a half yesrs'using after cleaning for 45 minutes, but the difference had no statistic meaning. Condusions The elesnliness of laminar operation rooms will drop as time prolonged, Amount of particulates in indoor air will in-crease too but the cleanliness can be ensured by extending cleaning time. After the quality assurance sys-tem was established the amount of smile particulates is still within the standard level
