ABSTRACT
Objective To investigate the occurrence of postoperative healthcare-associated infection(HAI)and its risk factors in neurosurgical patients undergoing removal of intracranial tumor,so as to provide theoretical basis for formulating intervention measures.Methods Prospective survey was adopted to monitor the occurrence of postoperative HAI in patients who admitted to the department of neurosurgery of a hospital and underwent selective removal of intracranial tumor between April 2013 and December 2014 ,risk factors for HAI were analyzed with univariate and multivariate logistic regression analysis.Results A total of 1 218 patients were surveyed,163 patents developed 193 times of postoperative HAI,inci-dence of postoperative HAI was 13.38%,case incidence of HAI was 15.85%.The main HAI site was intracranial site(n=125,64.77%),the next was lower respiratory tract (n=55,28.49%).Multivariate logistic regression analysis showed that operation grade and subtentorial operation were independent risk factors for postoperative HAI in neurosurgical patients undergoing removal of intracranial tumor,OR and 95%CI were 4.352(1.878-10.080)and 1.812(1.280-2.564)respec-tively.Conclusion Risk of postoperative HAI in neurosurgical patients undergoing high grade operation and subtentorial removal of intracranial tumor is high,effective prevention and control measures should be taken to prevent the occurrence of HAI.
ABSTRACT
OBJECTIVE The research aimed to investigate the incidence,clinical characteristics and risk factors of nosocomial infection in patients with mechanical ventilation in ICU,and explore the corresponding prevention procedures.METHODS Active surveillance was carried out by professional fulltime staff.The patients with mechanical ventilation in ICU above 48 hours were selected for the hospital infection surveillance,and the patients after tracheal intubation within 48 hours were also included.RESULTS The incidence of nosocomial infection was 54.28%,and the nosocomial infection were found in 69(65.71%) of the 105 cases.The major complication was mechanical ventilator-associated pneumonia(VAP).The risk factors were more than four times invasive operation and,tracheotomy(P
ABSTRACT
OBJECTIVE To realize the situation of nosocomial infection and usage of antibiotic in order to prevent and control nosocomial infection effectively. METHODS According to the request of countrywide nosocomial infection net,using the method of clinic investigation and case history investigation,we have investigated the infection complexion about all patients in 19 May 2006 and 24 May 2007,including the duration,transferring department and dead case.Then to analyze the comparison between two results. RESULTS 3489 cases were investigated,including 186 infection cases.The prevalence rate of nosocomial infection was 5.33%.Five departments had the high prevalence rate of nosocomial infection.They were hematology department,ICU,pediatrics department,neonatal unit and cadre ward.The highest rate was 31.30%.The lowest was 0.The infection site focused on lower respiratory tract.The antibiotic utilizing rate was high. CONCLUSIONS Enhanceing the management of nosocomial infection in key departments,regulating the antibiotic utilizing,to reduce the prevalence rate of nosocomial infection.
ABSTRACT
OBJECTIVE To explore the characteristic of nosocomial infection and formulate the effective measures of nosocomial infection management. METHODS According to the underlying disease condition and method ICD10,the infection data were to classifed and colleced which including of 160 795 cases during 2003-2006.Then the prospective and retrospective investigation were done for studying the nosocomial infection condition. RESULTS The nosocomial infection rate was 4.69%. The highest infection rate was caused by hematological disease (15.43%). By site of infection the upper respiratory infection rate was 35.34%,the lower respiratory infection rate was 28.22%,the gastrointestinal infection rate was 6.82%,and the intra-abdominal infection was 3.75%. In these infection cases,G-bacteria infection occupied 58.35% (which ranked No.1 in all pathogens),and the fungal infection occupied 17.09%. CONCLUSIONS In order to reduce the infection rate,we must enhance the work of preventing the key diseases,standard the measures of disinfection and isolation,increaseing the quarantine inspection rate and applying antibiotic according to the results of antifugal susceptibility testing.
ABSTRACT
OBJECTIVE To discuss the available methods of preventing the mattress pollution in the wards of the(hospital), and to keep the mattresses clean and dry and eliminate the hidden danger of nosocomial infection.(METHODS) The mattress protective covering is used of a new type of textile materials,and then applied into clinic.Selected 100 pieces of mattresses in the wards,divided them equally into two groups at random,the(experimental) group and the control group.After cleaning and pasteurization(surface) sampling and bacterial culturing for every mattress were undertaken.For the experimental group,spread the protective(covering) before the sheet,and for the control group,used the sheet directly.The colony number of each group was compared in the 3rd,7th,and 14th days.RESULTS The mattresses of experimental group were clean,light polluted and with less colonies,and that of the control group were heavy polluted and with more colonies.The comparisons of the total colony number and the number of every sampling point in the 3rd,7th,and 14th days of the two groups showed that there was a(significant) difference(P
