Comparative study in two preservation methods of the sputum aspirator nozzle / 中国实用护理杂志

ABSTRACT

Objective To explore a simple and safe method for preservation of the sputum aspirator nozzle. Methods Using self-controlled method, the traditional method was to place the nozzle in the glass bottle of disinfectant liquid, the modified method was to fix a sputum tube to a suitable location of the sputum aspirator or bedside with the joint free, after sputum aspiration,the nozzle was connected to the joint. One patient used the same sputum aspirator. The two methods of preservation were alternated every 24 hours. The slippage times of the nozzle were compared, and samples from glass nozzle and joints of disinfectant liquid bottles/spu-tuna tube joints were underwent bacterial culture. Results Significant difference existed in slippage times of the nozzle, the positive rate of bacteria colony in the.glass nozzle and disinfectant liquid bottles/sputum tube joints between the two methods. Conclusions Using sputum aspiration tubes to fix the nozzle of aputum aspi-rator is better than the traditional method of putting the nozzle into the glass bottle of disinfectant liquid,this method proves to be easy, safe,portable and economical and is worthy of clinical application.
