Cleaning and Sterilization of Laparoscopic Apparatus / 中华医院感染学杂志

OBJECTIVE To explore the best method of cleaning and sterilization of laparoscopic apparatus.METHODS Laparoscopic apparatus useed in the hospital was divided into four groups at random:with artificial cleaning and sterilization by ethylene oxide(EO),with machine-cleaning and sterilization by EO,with artificial cleaning by hydrogen peroxide plasma,and with machine-cleaning and sterilization by hydrogen peroxide plasma.And The sterilization effect of four groups was observed.RESULTS The positive cleaning result of manual with ultrasonic cleaning was 97.5%,but with autowash cleaner was 73.3%.The rate of qualification of artificial-groups was higher than machine groups obviously(P

Comparison of results of two routes of central venous catheterization / 肠外与肠内营养

Objectives:To compare the advantage and the disadvantage between the normally inserted central venous catheter(NICC) and the peripherally inserted central venous catheter(PICC). Methods:The patients were divided into two groups by different insertion methods:NICC group and PICC group.The success rate of first insertion point,the time of insertion, the symptom of patients during insertion, the complication of insertion and the rate of catheter septicemia were compared. Results:The group of PICC had a higher rate of successful insertion, a less time of insertion, a less time of insertion, a lower rate of complication, but a higher rate of catheter septicemia,when compared with the group of NICC. Conclusions:①PICC have some advantages being simple in insertion and of less complications.②The PICC patients have more chances to suffer from the catheter septicemia.③Perepheral venous inflammation and veno-occlusion more earily occurr in PICC patients.
