RESUMEN
Objective:To investigate the prognosis of intensive care unit(ICU)patients with carbapenem-resistant Klebsiella pneumoniae(CR-KP)infection.Methods:Clinical data of 86 elderly patients with KP infection admitted to our hospital from August 2017 to July 2019 were retrospectively analyzed.All patients were identified by the VITEK system and were tested by using the Kirby-Bauer paper diffusion method for drug susceptibility.Based on the existence of CR-KP, patients were divided into the non-resistance group(n=40)and the resistance group(n=46). The number of ventilator days, ICU days and clinical prognosis were compared between the two groups.Results:Specimens from sputum had the highest rate of KP isolation(46/86, 53.49%), followed by specimens from drainage fluid(16/86, 18.60%), blood(12/86, 13.95%), puncture wound fluid(3/86, 3.50%)and the tip of deep vein catheters(9/86, 10.46%). KP had high drug resistance to meropenem, and the drug-resistance rate was 53.49%(46/86). Compared with the non-resistance group, ventilator days and ICU days increased in the drug-resistance group[(60.75±72.86)d vs.(26.11±41.10)d, (73.41±63.32)d vs.(38.96±50.75)d, t=2.660 and 2.756, P=0.003 and 0.004]. The clinical effectiveness rate was higher in the non-resistance group than in the drug-resistance group(57.50% or 23/40 vs.23.91 % or 11/46, χ2=10.097, P=0.001). Conclusions:ICU patients with CR-KP have a higher number of ventilator days and longer ICU stays than those without CR-KP.In clinical practice, it is necessary to strictly follow the indications for antibiotic use, regularly perform bacterial identification and drug susceptibility tests, and diagnose KP infection as early as possible, in order to provide evidence for clinical diagnosis and treatment.

Objective To study the clinical significance of the change of plasma BNP levels in patients with grades sepsis and its correlation with the left ventricular ejection fraction.Methods One hundred patients of sepsis who were admitted in intensive care unit of Taizhou hospital were selected.It was divided into four groups:30 patients with septic shock,40 patients with severe sepsis,30 patients with sepsis and 20 persons without disease as control group.The concentration of plasma BNP was determined using sandwich immunoflurescence,and ultrasonic cardiogram was used to evaluate heart function and clinical features in all groups.To compare with the differences of the concentration of plasma BNP and the correlation between the concentration of Plasma BNP and LVEF in all groups,the data of clinical features,28-day mortality,prognostic values of BNP and the length of stay (ROG) in ICU were collected and compared.Result Plasma BNP levels in patients with septic shock[ (976.3 ± 160.7) pg/ml] were obvious higher than severe sepsis[ (648.4 ± 267.3) pg/ml ],sepsis [ (217.2 ± 89.7) pg/ml ] and control group [ (50.3 ± 25.4)pg/ml] (P ＜0.01).LVEF in patients with septic shock [ (48.2 ±9.6)% ] was obvious lower than severe sepsis[ (52.8 ±9.4)% ],sepsis[ (61.3 ± 8.9)% ] and control group[ (66.4 ±9.3)% ] (P ＜0.05 or P ＜0.01).It appeared to be inverse relationship between LVEF and the plasma BNP levels (r =-0.876,-0.724,P ＜0.01).BNP levels were significantly higher in non-survivors compared with survivors[ (1367.6±506.4)pg/ml vs (420.3 ±82.6)pg/ml,P ＜0.01 ].The receiver operating characteristic (ROG) curves indicated that values of areas under the curve of plasma BNP levels for 28-days mortality were 0.918(P ＜0.01).Conclusion The concentration of plasma BNP in patients was different in different grades of sepsis.It appeared to be negative correlation between the concentration of plasma BNP and LVEF.Plasma BNP levels had predictive value to the patients with sepsis.
RESUMEN
OBJECTIVE To investigate the characters of urinary noscomial infection in intensive care unit(ICU)of our hospital in order to reduce its incidence. METHODS The 661 patients in ICU of our hospital from Jan 2005 to Jun 2006 were analyzed,and in which 63 nosocomial urinary infection patients(9.53%) were found.We analyzed the 63 patients retrospectively. RESULTS Nosocomial urinary infection occurred in 9.53% patients admitted to the ICU.Nosocomial urinary infection in ICU was correlated with ages,using of antibiotics and hormones,duration of catheterization and APACHEⅡ score,but not with gender.The most prevalent pathogens of nosocomial urinary infection in ICU were fungi(40.66%),gram-negative bacteria(31.87%) and Gram-positive bacteria(27.46%).The clinical manifestation of nosocomial urinary infection in ICU was atypical. CONCLUSIONS Nosocomial urinary infection in ICU has its own characters which clinicians should pay more attention to.To reduce its incidence,we should avoid abusing of antibiotics and hormones,and make the duration of catheterization as short as possible.
