Objective:To explore the risk factors of sepsis in patients with multiple trauma and construct a nomogram prediction model.Methods:The data of patients with multiple injuries admitted to the emergency intensive care unit (EICU) of the General Hospital of Ningxia Medical University from January 2021 to April 2022 were respectively collected. Inclusion criteria: (1) meet the diagnostic criteria for multiple injuries; (2) the time from injury to admission ≤ 24 hours; (3) age>18 years old; (4) all examination or rescue measures were approved by the patient or the patient's family; (5) the patient's clinical data were complete. The patients were divided into sepsis group and non-sepsis group according to the definition of Sepsis 3.0 at the 28-day of EICU hospitalization. The receiver operating characteristic curve was drawn. Logistic regression analysis was applied to determine the independent predictors for sepsis, and the nomogram was constructed.Results:A total of 291 patients were included, including 102 in the sepsis group and 189 in the non-sepsis group. Multivariate logistic analysis revealed that age, acute physiology and chronic health status score (APACHE) Ⅱ, Glasgow Coma Scale (GCS), injury severity score (ISS), sequential organ failure assessment (SOFA) within 24 hours after admission, blood transfusion frequency, the application of norepinephrine, mechanical ventilation, pathogenic culture results, and history of diabetes were independent factors influencing the occurrence of sepsis. A nomogram model was constructed by combining these variables (AUC=0.913, 95% CI: 0.847-0.942), and the model had a good fitting calibration curve. Conclusions:The nomogram constructed by age, APACHE-Ⅱ, GCS score, SOFA score, ISS score, number of blood transfusions, mechanical ventilation, norepinephrine drug use, pathogenic culture and diabetes has a good predictive value for sepsis in patients with multiple trauma in the later stage, which is worth promoting.

Objective:To analyze the risk factors which may lead to tracheostomy in patients receiving invasive mechanical ventilation (IMV) in emergency intensive care unit (EICU).Methods:A case-control study was adopted to retrospectively analyze the clinical data of patients hospitalized in EICU receiving IMV from August 2016 to August 2019. The clinical data of patients were extracted through the electronic medical record system of the hospital information database. Patients were divided into the tracheostomy group and successful extubation group according to whether they received tracheostomy during hospitalization. The different clinical characteristics of the two groups were compared, and logistic regression was used to analyze the independent risk factors of tracheostomy.Results:A total of 109 patients were included in this study, among which, 53 patients underwent tracheotomy and 56 patients were successfully extubated. Logistic regression showed that GCS score ≤ 8 ( OR=5.10, 95% CI: 1.68-15.42, P < 0.01), cervical spinal cord injury ( OR=10.32, 95% CI: 2.74-38.82, P < 0.01), and sepsis ( OR=3.45, 95% CI: 1.39-8.54, P<0.01) were independent risk factors of tracheostomy for patients receiving IMV in EICU. Conclusions:If patients receiving IMV have GCS score ≤ 8, cervical spinal cord injury, or sepsis, they should be given more attention, because they may need early tracheostomy to save lives and improve the prognosis.

Objective:To explore the prognostic risk factors of patients with multiple injuries and establish a nomogram prediction model.Methods:The clinical data of 291 patients with multiple injuries admitted to the Emergency Intensive Care Unit (EICU) of General Hospital of Ningxia Medical University were collected, including sex, age, open injury, norepinephrine use, mechanical ventilation, time to hospital after injury, distance to hospital, relative lymphocyte value, platelet count, lactic acid, injury severity score (ISS), acute physiology and chronic health evaluationⅡ (APACHE Ⅱ), Glasgow coma scale (GCS), number of blood transfusions, number of operations, and previous history of diabetes, hypertension and smoking within 24 h after admission. According to whether the condition worsened during the hospitalization of EICU, the patients were divided into the deterioration group and improvement group. SPSS26.0 software was used for statistical analysis of the data, univariate and multivariate analysis were used to screen the factors affecting the prognosis of patients with multiple injuries, receiver operating characteristic (ROC) curve and forest chart were drawn, and the influencing factors in binary Logistic regression model were used to make the nomogram.Results:Mechanical ventilation, norepinephrine use, age, relative lymphocyte value, lactic acid, APACHE-II score, GCS score, and number of operations were significant for predicting the prognosis of patients with multiple injuries ( P<0.05). The independent influencing factors obtained by binary Logistic regression model were age, lactic acid, APACHE-Ⅱ score and number of operations. ROC curve analysis showed that the area under the curve was the largest in multi-factor combined prediction, followed by APACHE-Ⅱ score. The diagnostic cut-off value of each index was as follows: age >58 years old, relative lymphocyte value≤ 8.62%, lactic acid >1.72, APACHE-Ⅱ score >16, GCS score≤ 6, and number of operations≤ 0. The R software was used to establish a nomogram of the influencing factors in the binary Logistic regression model, which had good predictive value. Conclusions:The nomogram constructed by age, relative lymphocyte value, lactic acid, APACHE-Ⅱ score, GCS score, number of operations, mechanical ventilation, and norepinephrine use has a good predictive value for the prognosis of patients with multiple injuries, and is worthy of promotion..

Objective:To explore the relationship between hematocrit, early fluid therapy, and clinical outcomes in patients with septic shock, and to provide evidence for fluid resuscitation therapy and prognosis assessment in these patients.Methods:The clinical information of patients with septic shock who were diagnosed and treated in the Emergency Intensive Care Unit (EICU) of the First Affiliated Hospital of Wenzhou Medical University from January 1, 2018 to December 31, 2020 were collected. Taking the survival or death of patients 28 days after admission as the end point of clinical research, the patients were divided into the survival and death groups. After analyzing the basic data of the two groups, the univariate and multivariate COX regression analyses were used to analyze the evaluation value of Δ Hematocrit (HCT) d2-d1 and ΔHCT d3-d1 on the prognosis of patients with septic shock. At the same time, the Kaplan-Meier survival curve was used to analyze the overall survival rate of patients with septic shock, and the smooth curve fitting graph was used to verify its relationship with net fluid intake and death. Results:There were 241 cases in the survival group and 67 cases in the death group. Univariate COX analysis showed statistically significant differences between the survival and death groups in acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) ( P=0.0006), red cell volume distribution width (RDW) ( P=0.0043), age ( P=0.0184), ΔHCT d2-d1 ( P=0.0136), ΔHCT d3-d1 ( P=0.0204), and white blood cell (WBC) ( P=0.0444). Multivariate COX analysis showed that ΔHCT d2-d1 ( P=0.0115) and ΔHCT d3-d1 ( P=0.0029) were independent risk factors for death in EICU patients with septic shock. ΔHCT d2-d1 and ΔHCT d3-d1 were divided into three groups according to the three-digit method. The Kaplan-Meier survival curve showed no significant difference among the three groups in the overall survival rate related to ΔHCT d2-d1 ( P=0.16), but there was a statistically significant difference in the overall survival rate among the three groups related to ΔHCT d3-d1 ( P=0.025). The smooth fitting curve of ΔHCT d3-d1, net fluid intake, and prognosis showed that ΔHCT d3-d1 was negatively correlated with net fluid intake, and the middle ΔHCT d3-d1 group had the best prognosis. Conclusions:The value of ΔHCT d3-d1 is related to the net fluid intake of patients with septic shock. An appropriate decrease in HCT on the third day can improve the prognosis of patients with septic shock. The dynamic changes of hematocrit can provide a certain basis for fluid resuscitation and prognosis evaluation in patients with septic shock.

Objective:To investigate the clinical features, risk factors and prognosis of Clostridium difficile infection/colonization (CDI/CDC) in emergency intensive care unit (EICU) of Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine, then provides theoretical basis for clinical treatment. Methods:A retrospective case-control study was conducted. The data of EICU patients admitted to Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine from June 2016 to June 2020 were collected. Taking the CDI/CDC patients as research objects [ Clostridium difficile (CD) positive group] and the CD negative patients with the same gender and age difference less than 5 years who were admitted to the hospital during the same period as the control (CD negative group). Demographic information, risk factors, prognosis and stool samples were collected. Single factor analysis and binary Logistic regression were used to analyze the CD positive infection rate, risk factors, and hospital death of patients with different clinical characteristics. Results:About 487 patients in EICU were included, 76 cases were taken into CD positive group, CD positive rate was 15.6%, including CDI 11 cases, CDC 65 cases. Among the CD positive group, all of the cases used proton pump inhibitor (PPI), and 75 cases used at least one antibiotic. Seventy-six CD negative patients with or without diarrhea (CD negative group) were included in this study. Among them, 75 patients used PPI and 74 patients used at least one antibiotic. Univariate analysis showed that acute physiology and chronic health evaluation Ⅱ (APACHEⅡ), duration of hospitalization, and carbapenem use were the risk factors for CDI/CDC. There were significant differences in the above indicators between CD positive group and CD negative group [APACHEⅡ: 18.0 (12.2, 25.8) vs. 10.0 (7.0, 14.0), duration of hospitalization (days): 46.0 (30.5, 72.5) vs. 18.5 (9.2, 37.0), proportion of carbapenems: 81.6% (62/76) vs. 64.5% (49/76), all P < 0.05]. Binary Logistic analysis regression analysis showed that APACHEⅡ score [odds ratio ( OR) = 0.802, 95% confidence interval (95% CI) was 0.730-0.882, P < 0.01] and duration of hospitalization ( OR = 0.960, 95% CI was 0.942-0.978, P < 0.01) were independent risk factors for CDI/CDC. There was no difference in overall mortality between the CD positive group and CD negative group [27.6% (21/76) vs. 38.2% (29/76), P = 0.167]. Conclusions:Critically ill patients in EICU routinely use PPI and antibiotics, and the use of antibiotics does not affect the CD positive rate. The independent risk factors of CDI/CDC are the APACHEⅡ score and the duration of hospitalization, but fecal CD positive has no obvious influence on death.

Objective To investigate whether the nursing staff scheduling pattern of different shifts in Emergency Intensive Care Unit (EICU) of a third-grade first-class hospital in Guizhou Province could be rationally arranged by using the therapeutic intervention scoring system-28 (TISS-28). Methods The nursing workload of 129 patients in EICU was evaluated by TISS-28 from March to June 2017 in the Affiliated Hospital of Guizhou Medical University to look for the best nursing staff scheduling pattern. Results The TISS-28 was used to predict the workload of nurses on night shift and day shift. The TISS-28 scores of day shift and night shift were similar, and they were respectively 38.75±5.01 and 38.66±5.04 scores. There was no statistical significant difference in predicting the nurse-patient ratio between day shift and night shift by using TISS-28 (1 :0.83±0.22 vs. 1 :0.83±0.24, P > 0.05). The number of nursing staff was adjusted from originally 9 nurses during day shift and 5 nurses during night shift to 7 nurses during day shift and 7 nurses during night shift. Conclusions According to TISS-28 score to arrange the numbers of nurses on night shift and day shift is reasonable, the nurse workload of night shift can be reduced and their working enthusiasm improved, thus the degrees of satisfaction of nurses and patients are getting higher.

Objective To investigate the characteristics of pathogens and risk factors of the catheterassociated infection (CAI) in emergency ICU (EICU) in order to design an appropriately therapeutic strategy for the future.Methods From January 2008 to December 2010,a total of 1363 patients were enrolled for this retrospective study.Blood sample taken from the vein with indwelling catheterization and the tips of catheters cut in 5 cm after withdrawn from the veins in 1363 patients were collected for bacterial culture.Results Of 1363 catheters,pathogens were found in 147 (10.79%) after venous catheterization.The daily occurrences of CAI were 3.05 ones per 1000 catheters.Of 147 cases of infection,46.94% pathogens were gram-negative bacilli,40.14% gram-positive cocci,and 12.92% fungi.Unconditional Logistic regression analysis suggested that repeated catheterization,femoral vein catheterization,the application of multi-lumen catheter and long-term indwelling catheterization were the independent risk factors responsible for CAI.Conclusions The risk factors responsible for catheter related infections should be controlled to prevent the occurrence of nosocomial infection.

BACKGROUND:Catheter-related infection (CRI) of the central vein is a common cause of nosocomial infection. This study was undertaken to investigate the pathogen culturing and risk factors of CRI in emergency intensive care unit (EICU) in order to provide the beneficial reference.METHODS:From January 2008 to December 2010, a total of 1363 patients were subjected to catheterization. In these patients, the peak CRI rate of the patients was determined by bacterial cultivation and blood bacterial cultivation.RESULTS:CRI happened in 147 of the 1363 patients using the central venous catheter. The peak rate of CRI was 10.79%, with an incidence of 3.05 episodes per 1000 catheter days. Of the 147 patients, 46.94% had gram-negative bacilli, 40.14% had gram-positive cocci, and 12.92% had fungi. Unconditional logistic regression analysis suggests that multiple catheterization, femoral vein catheterization, the application of multicavity catheter, and the duration of catheterization were the independent risk factors for CRI.CONCLUSION:The risk factors for catheter-related infections should be controlled to prevent the occurrence of nosocomial infection.

OBJECTIVE The status and risk factors of nosocomial infection(NI) in patients in emergency intensive care units were invrstigated to make the intervention strategy. METHODS The prospective monitoring and retrospective investigation were used analyze the 72 nosocomial infection patients in EICU. RESULTS Incidence rate of NI in patients in EICU was 29.50%. It was significantly higher than average incidence rate of NI of the whole hospital at the same time; ≥60-year-old of rate of NI in patients was 60.52%; The average hospitalization days were 28 days; The lower respiratory tract was the most common infection site. The most common infection microorganism in EICU was Gram-negative bacteria. CONCLUSIONS The incidence rate of EICU is much higher than that in other departments. The invasive procedure, the quality of disinfection and sterilization, and patients immunity status especially in the old. were the risk factors General intervention strategy should be adopted in the control of EICU nosocomial infection to reduce the infection rate and raise the rescue rate.
