Related factors of nosocomial infection in severe thoracic trauma patients after operation

Objective To investigate the related factors of nosocomial infection after severe thoracic trauma so as to provide basis and interventions for lowering nosocomial infection rate. Methods A retrospective case series study was conducted in 148 cases of severe thoracic trauma surgically treated from January 2014 to January 2016. There were 98 males and 50 females with an average age of 34.7 years. The abbreviated injury scale (AIS) was ≥ 3 points. The incidence of nosocomial infection was statistically analyzed. The possible factors related to nosocomial infection were analyzed, including age, gender, previous basic diseases, coma, blood transplantation, surgical procedure, operation time, tracheal intubation time, postoperative tracheotomy, and postoperative ICU hospitalization. Results Nosocomial infection occurred in 18 cases, with infection rate of 12.2%. There were 11 cases of pulmonary infection, four urinary tract infection, two incision infection, and one thoracic cavity infection. There were four cases (22%) of Gram-positive bacteria as pathogen, both of which were Staphylococcus aureus. A total of 12 cases (67%) were Gram-negative bacteria, among which four were infected with Klebsiella pneumonia, three with Acinetobacter baumannii, three with Pseudomonas aeruginosa, and two with Escherichia coli. Two cases were infected by fungi. The incidence of infection was correlated with the patients' age (≥60 years), previous basic disease, coma, operation methods, operation time (≥3 hours), endotracheal intubation time (≥24 hours), tracheotomy after surgery, and postoperative hospitalization duration in the ICU (P<0.05), rather than gender and blood transplantation. Conclusions The most common pathogen of nosocomial infection in severe thoracic trauma patients is Gram-negative bacteria. The older age, previous basic diseases, coma, thoracotomy, long operation time, long tracheal intubation time, tracheotomy and long ICU hospital stay are the risk factors for nosocomial infection. More attention should be paid to these risk factors in order to minimize the occurrence of postoperative hospital infection, and to reduce the harm to patients.

Monitoring and analysis of the relevant factors and strategies of nosocomial infection in intensive care unit

Objective To investigate the characteristics of nosocomial infections and factors in patients in intensive care unit （ ICU） ,in order to provide a basis for the measures .Methods Using the method of target monitoring , to the patients who were in the ICU from January 2013 to December had a prospective surveillance , statistics and analysis the monitoring data .Results There were 163 cases happened nosocomial infection in 677 cases of patients, hospital infection rate was 24.1%;212 cases of secondary infection , infection cases rate was 31.3%. The main site of infection followed by respiratory tract （ 143 cases, 67.5%）, blood （28 cases,13.2%）, urinary tract （15 cases, 7.1%）.The main pathogen of infection followed by Acinetobacter baumannii （64 strains, 30.2%）, Pseudomonas aeruginosa （35 strains, 16.5%） and Klebsiella pneumoniae （24 strains, 11.3%）.Different age, hospitalization, the number of disease diagnosis at ICU hospitalized , mechanical ventilation time and presence of detaining urethral catheter for endotracheal intubation , deep venous catheterization , indwelling catheters in patients with the incidence of comparative differences were statistically significant （P〈0.05）Conclusions Should take appropriate prevention and control measures for related factors of nosocomial infection in ICU , strict aseptic procedures and disinfection and isolation system , strengthen the hand hygiene , good management of invasive procedures , try to shorten the hospital stay of patients , rational use of antibiotics and so on are the key measures to reduce the nosocomial infections in ICU .

Analysis and prevention of nosocomial infection related factors in elderly patients with cardiovascular disease

Objective To explore the related factors of nosocomial infection in elderly patients with cardiovascular disease.Methods From January 2011 to December 2012 in our hospital,2530 cases of elderly cardiovascular patients were selected for study objects to observe effects of the related factors of nosocomial infection to elderly patients with cardiovascular disease.Results 248 patients from 2530 cases with cardiovascular disease developed nosocomial infection,the proportion was 9.8％.The nosoeomial infection rate of patients aged over 70 years was 15.4％,the nosocomial infection rate of those aged under 70 years was 6.7％; the nosocomial infection rate of the patients with heart functional class Ⅰ-Ⅱ was 6.1％,the nosocomial infection rate of the patients with heart functional class Ⅲ-Ⅳ was 15.8％; the nosocomial infection rate of the patients with the implementation of invasive diagnosis and treatment measures was 19.7％,the nosocomial infection rate of the patients without the implementation of invasive diagnosis and treatment measures was 6.7％,the nosocomial infection rate of the patients with prophylactic use of antibiotics was 13.7％,the nosocomial infection rate of the patients without prophylactic use of antibiotics was 8.2％.The logistic regression analysis showed that the patients' age,cardiac function,prevention of the use of antibiotics and the implementation of invasive treatment measures were significant.Conclusion The main factors affecting nosocomial infection in elderly patients with cardiovascular disease were the age of patients,cardiac functional grading,antibiotic prophylaxis and invasive treatment measures.

Effect of nursing intervention in nosocomial infection control in direct rooming-in management

Objective To study the causes and related factors of nosocomial infection after direct rooming-in management and explore the measurements to decrease incidence rate. Methods The data information was monitored and analyzed retrospectively on basic nursing, patients behavior intervention, ward air disinfection, respiratory tract nursing, hand sanitary control of medical care personnel in neonates and moms with direct rooming-in management from January 2006 to December 2009 in the hospital. Results The incidence of nosocomial infection after direct rooming-in management was 0.47%. Infected part was mainly the lower respiratory tract infection (38.1%).Conclusion Strengthening maternity nosocomial infection knowledge of nursing staff training, strengthen early maternal and accompanied protect personnel to implement the hospital infection related knowledge of mission, strengthen the work of maternal and infant direct rooming-in management, strengthening basic nursing, pay attention to hand hygiene, on the prevention and control of maternaldirect rooming-in management nosocomial infection all play the very important role. It suggested that strengthening the disinfection and isolation management for hospital ward and basic nursing measurements could play a very important role in prevention and control to nosocomial infection induced by infant & mom rooming-in.
