Abstract
Objective To evaluate the disinfectant efficacy of ethanol on transparent PVC endotracheal tube , as well as the best replacement time. Methods Phase Ⅰ: 58 patients with transparent PVC endotracheal tube between April and July 2011 were selected , the concentration and bacterial count of ethanol used for immersion disinfection of transparent PVC endotracheal tube were detected at different time point (upon opening of the new ethanol and 12, 24, 48 and 72 h after opening ) , ethanol was used continuously for 72 h . Phase Ⅱ: 46 patients with transparent PVC endotracheal tube between July and November 2011 were selected and divided into experimental group (new process; immersion tank and ethanol were changed every 48 h) and control group (former process; immersion tank and ethanol were changed every 24 h) , the frequency of change, manpower, cost and incidence of infection within one month between two groups were compared . Results The difference between ethanol upon opening and 12, 24 as well 48 h after opening were not statistically significant (all P>0. 05) ;72 h after opening, ethanol concentration was significantly lower than the newly opened ([71. 82 ± 0. 77]%vs [72. 98 ± 0. 83]% ,t = 17. 60,P<0. 05). Disinfection efficacy of ethanol at different time points all met the required standards. Cost of experimental group was significantly lower than the control group (CNY[56. 70 ± 9. 30] vs CNY[l78. 20 ± 4. 70]) , and manpower was also significantly lower than the control group ([37. 20 ± 5. 80] person-time/month vs [120. 30 ± 6. 70] person-time/ month,all P<0. 05); Incidence of infection was not statistically significant between two groups (13. 04% vs 17. 39%,t=0. 17,P>0. 05). Conclusion Ethanol immersion disinfection is a effective, low cost, easy operation and safe disinfection method, ethanol can be used continuously for 48 hours before changed if ethanol tank is sealed well and with low opening frequency.关键词
