OBJECTIVE: To assess the temporal relationship between ICU-acquired infection (IAI) and the prevalence and severity of organ dysfunction or failure (OD/F). DESIGN AND SETTING: Observational, single center study in a mixed intensive care unit of a university hospital. PATIENTS: We analyzed 1,191 patients hospitalized for more than 2 days during a 2-year observation period: 845 did not acquire IAI, 306 of whom had infection on admission (IOA); 346 did acquire IAI, 125 of whom had IOA. MEASUREMENTS AND RESULTS: The SOFA score was calculated daily, both SOFAmax, the sum of the worst OD/F during the ICU stay, and SOFApreinf, the sum of the worst OD/F existing before the occurrence of the first IAI. The SAPS II and SOFA score of the first 24 h were significantly higher in patients with than in those without IAI. SOFApreinf of IAI patients was also higher than the SOFAmax of patients without IAI both in patients with (12.1+/-4.6 vs. 8.9+/-4.7) and those without IOA (9.2+/-4.0 vs. 6.7+/-3.5). SOFApreinf represented 85.7% of the value of SOFAmax in patients with IAI. SOFApreinf increased significantly with the occurrence of sepsis, severe sepsis, or septic shock during ICU stay. Severe sepsis and septic shock during ICU stay as well as SOFApreinf were part of the factors associated with hospital mortality. CONCLUSIONS: IAI is significantly associated with hospital mortality; however, its contribution to OD/F is minor. Moreover, severity of IAI seems to be related to previous health status. [less ▲]

Over the last ten years, much progress has been achieved in intensive care medicine. Large randomized studies, most often their multicentric, were performed and their results were translated into rules to be followed for the most appropriate treatment of life-threatening organ failures. The place of non-invasive ventilation in the management of hypercapnic or hypoxic respiratory insufficiencies was thus defined, and the methods for less traumatic mechanical ventilation were specified. The techniques of renal replacement therapy were compared and the optimal doses of dialysis or hemofiltration were established. The metabolic support of the patients was also altered following landmark studies, such as the management of blood glucose, which deeply influenced the approach to critically ill patients. [less ▲]

Introduction Combination antibiotic therapy for ventilator associated pneumonia (VAP) is often used to broaden the spectrum of activity of empirical treatment. The relevance of such synergy is commonly supposed but poorly supported. The aim of the present study was to compare the clinical outcome and the course of biological variables in patients treated for a VAP, using a monotherapy with a beta-lactam versus a combination therapy. Methods Patients with VAP were prospectively randomised to receive either cefepime alone or cefepime in association with amikacin or levofloxacin. Clinical and inflammatory parameters were measured on the day of inclusion and thereafter. Results Seventy-four mechanically ventilated patients meeting clinical criteria for VAP were enrolled in the study. VAP was microbiologically confirmed in 59 patients (84%). Patients were randomised to receive cefepime (C group, 20 patients), cefepime with amikacin (C-A group, 19 patients) or cefepime with levofloxacin (C-L group, 20 patients). No significant difference was observed regarding the time course of temperature, leukocytosis or C-reactive protein level. There were no differences between length of stay in the intensive care unit after infection, nor in ventilator free days within 28 days after infection. No difference in mortality was observed. Conclusion Antibiotic combination using a fourth generation cephalosporin with either an aminoside or a fluoroquinolone is not associated with a clinical or biological benefit when compared to cephalosporin monotherapy against common susceptible pathogens causing VAP.

Abstract Objective: To compare the efficacy and safety of adjusted-dose unfractionated heparin with that of regional citrate anticoagulation in intensive care patients treated by continuous venovenous hemofiltration (CVVH). Design and setting: Prospective, randomized, clinical trial in a 32-bed medical and surgical ICU in a university teaching hospital. Patients: ICU patients with acute renal failure requiring continuous renal replacement therapy, without cirrhosis, severe coagulopathy, or known sensitivity to heparin. Interventions: Before the first CVVH run patients were randomized to receive anticoagulation with heparin or trisodium citrate. Patients eligible for another CVVH run received the other study medication in a crossover fashion until the fourth circuit. Measurements and results: Fortynine circuits (hemofilters) were analyzed: 23 with heparin and 26 with citrate. The median lifetime of hemofilters was 70 h (interquartile range 44–140) with citrate anticoagulation and 40 h (17–48) with heparin (p=0.0007). One major bleeding occurred during heparin anticoagulation and one metabolic alkalosis (pH=7.60) was noted with citrate after a protocol violation. Transfusion rates (units of red cells per day of CVVH) were, respectively, 0.2 (0.0–0.4) with citrate and 1.0 (0.0–2.0) with heparin (p=0.0008). Conclusions: Regional citrate anticoagulation seems superior to heparin for the filter lifetime and transfusion requirements in ICU patients treated by continuous renal replacement therapy. [less ▲]
