ABSTRACT
OBJECTIVE To discuss the practicality of using the nylon nets,which are derived from disposed used medical(suture-band).The nylon nets were attached to the filtering apparatus on original return-wind exit on the lateral wall of surgical operating room.METHODS The velocity of wind,concentration of bacteria and the total(particle) amount of dust were determined by contrasting the number determined before and after passing the nylon nets on the(filtering) apparatus return-wind exit.RESULTS There was no evidence to influence the cleaning and temperature(regulating) effects of air conditioner by binding the nylon nets on them.CONCLUSIONS This method appears to save time as well as energy to work more efficiently than cleaning air conditioners weekly.
ABSTRACT
OBJECTIVE To investigate the infection rate and observe the healing courses of the incision after the open procedures of the suppurative appendicitis,which was managed by positioning drainage tube under the fatty layer of the incision.METHODS The infection rate,manifestation of the incision,and the mean time in hospital were observed after the drainage tube in the incision was employed.RESULTS The infection rate(9.30%) and the mean time in hospital(6.63?1.95days)dropped significantly(P
ABSTRACT
OBJECTIVE To provide the investigative data for timely changing medical gloves according to the study on the dynamic change of physical property of the gloves during abdominal open procedure.METHODS The gloves used in the abdominal open procedures were collected.The tensile strength,break elongation and the morphological values of three types of the gloves(No.6.5,7 and 7.5) were measured and recorded before and after their using at the time point of 0.0h,1.5h,2.5h,3.5h,4.5h,5.5h and 6.5h during operation.RESULTS The tensile strength decreased significantly(P
ABSTRACT
OBJECTIVE To investigate the sterilizing effect of Avagard surgery wasting liquid.METHODS All the staff on operation were divided into two groups at random,each no less than 50 persons.Both groups were sterilized by 4% Avagard surgery washing liquid.In one group,hands and forearms were smeared by 0.5% Avagard fast surgery washing liquid(smearing group),the other group was not smeared by 0.5% Avagard fast surgery washing liquid(no-smearing group).In both groups the samples were derived from fingers and cultured right after sterilization and at intervals of 1h,2h,3h,4h,5h and 6h during operation,and to investigate the sterilization effect.RESULTS The bacteriological detections of both groups in all times showed that the number of colony was0.05).CONCLUSIONS The results of the experiment show that 4% Avagard surgery washing liquid is reliable for its sterilizing effect and easy to use.The duration of antibacterial effect is no less than 6 hours,this method could reduce the cost of the operation and improve the efficiency of work.
