Application of Microbiological Examination Technology in Infection Control
Objective: To explore and study the application value of microbial testing technology in infection control.
Methods: 288 patients with urinary tract infection were selected from June 2012 to June 2013, and 288 strains of Escherichia coli were isolated from urine. They were randomly divided into two groups, each group 144 strains, one of which was subjected to routine treatment and microbiological examination, and the other group was only subjected to routine treatment. To study and discuss the application value of microbiological examination in clinical infection control.
Results: The infection rate and infection rate of patients in the observation group were significantly lower than those in the control group (P
Conclusion: Microbiological examination can obviously reduce the incidence of infection, improve the control and treatment level of clinical infection, and has good clinical value, which is worthy of wide application in clinic.
Keywords: Microbiological examination, infection control and monitoring

With the continuous improvement of modern medical technology, many chemical drugs, interventional therapy and radiotherapy are widely used in clinic, and these treatments are easy to lead to the emergence of drug-resistant strains, leading to an increase in the incidence of hospital infection year by year. In the process of hospital treatment, patients are infected and have clinical symptoms of infection, which is hospital infection. This infection usually has a certain incubation period. Therefore, as long as the patient's infection symptoms belong to the category of hospital infection, they all belong to hospital infection. Hospital infection has become an important problem to be solved urgently in the medical field. From 20 12 years 10 to 20 13 June, 288 patients with urinary tract infection in our hospital were selected to study the clinical application effect of microbial testing technology in infection control. The results are as follows.
1 data and methods
1. 1 general information. From October 20 12 65438+ 10 to June 20 13, 288 strains of Escherichia coli were clinically isolated from 288 patients with urinary tract infection in our hospital, and they were randomly divided into two groups, each with 144 strains. Among them, male patients 156, female patients 132, aged 2-58 years, with an average age of 48.5? 6.5 years old. Average length of stay (18.5? 1.8) days. There was no significant difference in clinical data such as age, sex and hospitalization time between the two groups (P & gt0.05).
1.2 method. In the observation group, 44 strains of Escherichia coli/Kloc-0 were collected from 144 patients and detected by microbial detection technology. The specific operation is as follows: using ID32E test strip to purify and identify E. coli samples; ② ATB-5 test strip was used for drug sensitivity test; ③ Meria semi-automatic microbial analyzer was used for detection; ④ K-B method was used in the diagnosis experiment; ⑤ The observation group was given medication according to the test results, while the control group was given routine treatment.
1.3 statistical processing. SPSS 17.0 software; T test; P & lt0.05, with statistical significance.

The results of microbiological examination showed that the infection degree and infection rate in the observation group were lower than those in the control group (P
3 discussion
With the frequent application of various chemical drugs, interventional therapy, radiotherapy and antibiotics in clinic, nosocomial infections frequently occur, and the incidence rate gradually increases, which seriously affects the health of patients. Therefore, the diagnosis of nosocomial infection is imperative. At present, the most accurate diagnostic method is microbial detection technology, which can provide more and more accurate diagnostic information for doctors and provide scientific basis for further treatment. The diagnostic criteria of urinary tract infection are: frequent micturition, urgency, dysuria and incomplete micturition, but the situation is not serious, only occasionally. There are only traces of bacteriuria, hematuria, urine gas and pyuria in urine, and patients also have mild waist pain, which belongs to mild infection; Patients with frequent micturition, urgency, dysuria, urinary incontinence, bacteriuria, hematuria, pneumaturia, pyuria and other phenomena in urine. The patient has a pain in the waist, but it is tolerable. This situation belongs to moderate infection; The patient began to have frequent urination, frequent urination, dysuria and urinary incontinence, and the patient could not even control himself. Bacterial urine, hematuria, pneumothorax and pyuria in urine are serious, and the patient's back pain is unbearable. This condition is a serious infection.
Microbiological examination has become an important research direction in the medical field and one of the most important life sciences. Microbiological examination can effectively monitor clinical infection, guide the further diagnosis and treatment of clinical infection, and rationally use antibiotics. The important way to control nosocomial infection is to start from the source of infection, the route of transmission and the susceptible population, so as to effectively control the occurrence of infection. In the hospital, patients, doctors, nurses and even the hospital environment may be the source of infection. Therefore, hospitals should do a good job of disinfection every day, which can not be ignored. Medical staff should also pay attention to personal hygiene, often wash their hands and disinfect, and medical instruments and other supplies should also be disinfected to reduce infectious agents. There are many pathogens in the hospital, which is suitable for living in a humid environment. Therefore, it is necessary to control the hospital environment, keep the air open and reduce the occurrence of hospital infection. In addition, the patients in the hospital are weak and susceptible to infection, and most of them are susceptible people. Therefore, while maintaining the ward environment, we must strengthen the drug resistance monitoring of pathogenic bacteria and environmental bacteria.
In this study, the results of microbial detection in the observation group showed that the infection degree and infection rate of patients were lower than those in the control group, and the two groups were compared P
