对灭菌物品包装材料选择的调查 总被引:10,自引:0,他引:10
从无菌保存期与费用两方面对灭菌物品包装材料的选择进行了调查。结果,双层全棉布包装物品的无菌保存期约1周,纸塑袋包装者达1年。使用量较小与使用频率较低的物品,为减少因超过保存期而反复灭菌的次数,节约费用,以采用纸塑袋包装为好;使用量较大的物品则适宜用双层全棉布包装。 相似文献

[目的]研究双层棉布、无纺布及硬质灭菌盒的阻菌效果及成本效益,为临床选择合适的灭菌包装材料提供依据.[方法]采用分层随机对照实验,将实验对象分为3组,即棉布组、无纺布组及硬质灭菌盒组,均采用脉动真空压力灭菌后,在室温(22±2)℃,湿度50%~60%的环境下存放14 d、90 d及180 d后送细菌室检测,检测结果均无细菌生长.[结果]3种包装材料阻菌效果最好的为硬质灭菌盒,其成本也最低.[结论]临床包装材料的选择应根据实际情况综合考虑,棉布包装的实际成本比其他材料高、且灭菌有效期短;无纺布过多使用易产生医疗垃圾,污染环境;硬质灭菌盒性价比优于棉布及无纺布. 相似文献

不同灭菌方式对无菌物品有效期的影响 总被引:3,自引:0,他引:3
不同灭菌方法灭菌处理过的无菌物品储存有效期受到包装材料、封口的严密性、灭菌条件、储存环境等诸多因素影响。按照规范规定,对于棉布包装材料和开启式容器,建议在室温25℃以下保存2周,潮湿多雨季节应缩短保存时间。对于其它包装材料如一次性无纺布,一次性纸塑包装材料,如证实该包装材料能阻挡微生物渗入,其有效期可相应延长,至少为半年以上。不同的灭菌方式是否对无菌物品的有效期会有所影响尚不得而知,为此我们采用一次性纸塑包装材料使用不同的灭菌方式在不同的医疗环境中研究对无菌物品有效期的影响。1方法1.1试验组设计我们将4#手术… 相似文献

压力蒸汽灭菌过程中有个必要的干燥程序,以保证无菌物品在储存过程中保持无菌状态。预真空压力蒸汽灭菌干燥时间一般为7、10~15 m in和30 m in不等。干燥时间的差异导致灭菌工作所需的时间长短不一,如果能在不影响无菌物品保存有效期的情况下,缩短干燥时间,则可加快灭菌速度,提高工作效率,为此,我们对压力蒸汽灭菌干燥时间与灭菌包保存期限关系进行了研究。1方法1.1灭菌处理方法采用脉动真空压力蒸汽灭菌柜,所用器械包均使用15cm×15 cm×25 cm的双层布巾包装,包内放置132℃化学指示卡,包外贴3M指示胶带;每锅放置器械包180个,上、下层各90… 相似文献

无菌包有效期为7~14d,临床上有一些急救包,使用率不高,但长期处于备用状态,经常过期,重新灭菌既增加供应室的工作量,又增加临床护士的工作量,我们采用了一次性纸塑包装材料(下称“纸塑包装”)包装后,脉动真空蒸气灭菌,经细菌培养、刀片生锈情况、封口裂开情况的观察,将有效期定为3~6个月,深受临床各科欢迎,现报道如下。 相似文献

Influence of sterile protective sleeves on the sterility of pulmonary artery catheters 总被引:2,自引:0,他引:2
S O Heard R F Davis R J Sherertz M S Mikhail R C Gallagher A J Layon T J Gallagher 《Critical care medicine》1987,15(5):499-502
Eighty-seven pulmonary artery catheters (PACs) with sterile protective sleeves were placed into 69 surgical ICU patients by one of the following two methods: through an introducer placed in a new, percutaneous site or by exchanging an indwelling catheter for an introducer. On removal, 5-cm catheter segments from the catheter tip and from within the introducer and sleeve, peripheral blood, and blood drawn from the PAC distal port were cultured quantitatively. Sleeve segment cultures were sterile if catheterization was less than 48 h and had been accomplished through a new percutaneous site. The risk of growing greater than 10(3) colonies on the tip and introducer segment increased to greater than 30% when PACs were left in over 96 h. The incidence of catheter-related bacteremia (CRB), defined as the simultaneous growth of identical organisms from the blood and the PAC tip, was 5.3% but may have been underestimated. CRB was associated with the use of corticosteroids (p = .009) and with cultures from any PAC segment growing more than 10(3) colonies (p less than .01). Although our data suggest that the use of the sterile protective sleeve is associated with a low risk of colonization, further study will be required to delineate the relationship between the use of protective sleeves and CRB. 相似文献

Comparison of two sterile connection devices and the effect of sterile connections on blood component quality 总被引:1,自引:0,他引:1
BACKGROUND: Sterile connection devices (SCDs) are used to connect pieces of polyvinylchloride tubing between blood bag systems. After observing a slight decrease in inner diameter of tubing welded with the CompoDock S2 SCD, the effect of welded tubing on storage characteristics of white blood cell (WBC)-reduced red blood cells (RBCs) and platelet (PLT) concentrates was studied. Welds were made with Terumo SCD (T-SCD) or CompoDock S2, and unwelded tubing served as reference. STUDY DESIGN AND METHODS: Three WBC-reduced RBC units or 3 PLT concentrates were pooled and divided to prevent donor-dependent differences. The units were transferred 10 times over (1) tubing with a T-SCD weld, (2) a CompoDock S2 weld, or (3) unwelded tubing. RBCs were stored for 42 days and free hemoglobin (Hb) was measured; PLT concentrates were stored for 8 days and CD62P expression was measured, as markers for blood component quality (n = 10 paired experiments). RESULTS: WBC-reduced RBC units had similar hemolysis at the end of storage: 0.47 +/- 0.28, 0.47 +/- 0.35, and 0.49 +/- 0.38 percent of total Hb, for tubing with a T-SCD weld, a CompoDock S2 weld, or no weld, respectively (not significant). CD62P expression of stored WBC-reduced PLT concentrates was not significantly different between the groups: 20.3 +/- 5.1, 19.8 +/- 5.1, and 22.3 +/- 9.8 percent for tubing with a T-SCD weld, a CompoDock S2 weld, or no weld, respectively. CONCLUSION: The quality of blood components, measured as RBC hemolysis and platelet CD62P expression, is not adversely affected by the presence of a sterile connection in the tubing, made by either the CompoDock S2 or the T-SCD. 相似文献
