It has been contributed to public health that the hospital has multiplied in the aspect of number and has been a large size with development of modern medical science, meanwhile the problem of hospital infection is coming out seriously. Respiratory hospital infection among hospital infections develops very commonly from patients having taken the operation of intubation or tracheostomy, which results from a big factor that the infection developed from medical appliances used for respiration aids, contamination of solution and infection of medical staff. This study is separated into four steps-the time to use normal saline and distillation water for storaging catheter which are the cause of the infection of solution to store distillation water and catheter, not to say the catheter used when the patient who should get tracheostomy operation takes suction. The purpose of this study is to offer the basic data which are needed to check contamination degree as time goes by and nurse intervention and grope for a new nursing intervention.
The target of this study is hospitalized in an intensive care unit having 700 sickbeds which is located in IKSAN city and it targeted patients before 7 days passed after an operaion of a tracheostormy. Materials collected were analyzed by SPSS PC+ figures program.
The result of this study were as follows ;
1. The gradual contamination levels of the normal saline used in suction are showing that colony increase in proportion to the length of time.
2. while colony increases in normal saline with the lapse of time, distillation water mixed with 5cc of potadine did not show any sign of the formation of colony from its preparation until it was used for 8 hours.
3. Such variables as the period of intubation insertion, the length of hospitalization in I.C.U, the age and the level of contamination of normal saline have no inter-relationship. Therefore, as the length of normal saline used in suction, the contamination level increases with the excelleration of the contamination speed.
4. Regarding the number of suction and the contamination level of the normal saline. We can observe correlation contamination level in the 3 step of suction(mean value:13.4) and the saline which was used for one hours(r=0.702, P=0.001), four hours(r=0.694, P=0.001), eight hours(r=0.488, P=0.029). Further we can observe contamination in the 4 step of suction(mean value:17.8) well as saline used for eight hours; [for one hours(r=0.641, P=0.002), four hours(r=0.670, P=0.001), eight hours (r=0.574, P=0.008)].
Thesedays clinics use normal saline by changing it, three times a day. however, the timing of saline change and the current suction methoed should be changed given the one hour used normal saline contamination number 79.850. Regarding the number of suction and the contamination lend of the normal saline.
