不同方法清洗妇产科手术器械效果比较

Comparison of efficacy of different cleaning methods used in gynecological and obstetrical surgical instruments

目的比较不同方法清洗妇产科手术器械的效果,探寻有效的器械清洗方法。方法将某院妇产科门诊人流手术器械60套随机分为A、B、C3组,每组20套。A组采用多酶浸泡加手工清洗,B组采用多酶浸泡加机洗,C组采用超声联合机洗,比较3组清洗方法的清洗效果。结果采用目测和放大镜检测,C组合格率(99.78%)显著高于A组(73.48%)和B组(78.70%),差异均有统计学意义(均P<0.0125);A组与B组比较,差异无统计学意义(P>0.0125)。A组与B组非管腔类手术器械清洗合格率显著高于管腔类器械(均P<0.05)。采用隐血试验检测,C组合格率(99.16%)显著高于A组(75.00%)和B组(80.61%),差异均有统计学意义(均P<0.0125);A组与B组比较,差异无统计学意义(P>0.0125)。各组别管腔类器械与非管腔类器械清洗合格率比较,差异均无统计学意义(均P>0.05)。结论对于管腔、复杂类器械,在常规多酶浸泡的基础上,结合超声波后再机洗的方法,能有效提高器械清洗质量,确保灭菌效果。

Objective To compare the cleaning efficacy of gynecological and obstetrical surgical instruments by different cleaning methods, so as to find out the effective cleaning method. Methods SixtY sets of artificial abortion instruments used in an outpatient department of gynecology and obstetrics were randomly divided into 3 groups（A, B,C, 20 for each）, group A adopted multi-enzyme immersion in combination with manual clean, group B adopted multi-enzyme immersion combined with machine wash, and group C adopted ultrasonic clean with machine wash, cleaning efficacy of three groups were compared. Results Assessment by visual inspection and magnifying glass showed that the qualified rate of cleaning of group C was significantly higher than group A and B（99. 78% vs 73.48% ; 99. 78% vs 78. 70% % both〈0. 0125） ; group A and B was not significantly different （P〉0. 0125）. The qualified rate of cleaning of non-lumen instruments in group A and B were both significantly higher than lumen in- struments （both P〈0. 05）. Occult blood test result showed that the qualified rate of group C was signifieantly high- er than group A and B （99. 16% vs 75.00%; 99. 16% vs 80. 61 %; both P（0. 0125） ; group A and B was not sig- nificantly different （P〉0. 0125）. The qualified rate of cleaning between lumen and non-lumen instruments of three groups was not significantly different respectively （all P〉0. 05）. Conelusion On the basis of immersion in multienzyme, ultrasonic clean in combination with machine wash can improve the cleaning quality of intricate and lumen instruments and ensure the sterilization efficacy.
