Background: Younger patient age and relatively good prognosis have been described as factors that may increase caregiver motivation in treating patients with septic shock in the intensive care unit (ICU).

Objectives: To examine whether clinical teams tended to achieve unnecessarily higher map arterial pressure (MAP) values in younger patients.

Methods: We conducted a population-based retrospective cohort study of patients presenting with septic shock who were treated with noradrenaline and hospitalized in a general ICU between 2006 and 2018. The patients were classified into four age groups: 18-45 (n=129), 46-60 (n=96), 61-75 (n=157), and older than 75 years (n=173). Adjusted linear mixed models and locally weighted scatterplot smoothing (LOWESS) curves were used to assess associations and potential non-linear relationships, respectively, of age group with MAP and noradrenaline dosage.

Results: The cohort included 555 patients. An inverse relation was observed between average MAP value and age. Among patients aged 18–45 years, the average MAP was 4.7 mmHg higher (95% confidence interval 3.4–5.9) than among patients aged > 75 years (P-value <0.001) after adjustment for sex, death in the intensive care unit, and Sequential Organ Failure Assessment scores.

Conclusions: Among patients with septic shock, the titration of noradrenaline by staff led to a higher average MAP for younger patients. Although the MAP target is equal for all age groups, staff may administer noradrenaline treatment according to a higher target of MAP due to attitudes toward patients of different ages, despite any evidence that such practice is beneficial.

Background: Massive, non-compressible bleeding is a leading cause of preventable trauma mortality. Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) is a minimally invasive procedure in which a balloon catheter is maneuvered into the aorta to temporarily occlude large vessels and enable stabilization of the exsanguinating patient.



Objectives: To present experiences in assimilating REBOA at a single level 1 trauma center in Israel, to evaluate the technical aspects of the procedure, and to describe patient characteristics and outcomes.


Methods: This retrospective cohort study comprised civilians admitted with hemorrhagic shock to our trauma department who were treated with REBOA between November 2017 and July 2021. Descriptive statistics of the patients, characteristics of the injuries and patient outcomes are presented.


Results: The study included 22 patients (median age 30.1 years, 21 male). The mean systolic blood pressure (SBP) before REBOA inflation was 59.6 ± 11.4 mmHg, and the mean SBP measured after the procedure was 115.2 ± 26.3 mmHg. In 20 patients (91%), the SBP was normalized (> 90 mmHg) shortly after inflation of the balloon, and they survived the treatment in the trauma department; 15 (75%) survived the first 30 days.



Conclusions: REBOA is an effective method for the initial resuscitation and hemorrhage control of patients with massive, non-compressible bleeding and is relatively easy to assimilate in a hospital. The achievement of immediate normalization of SBP enables medical personnel to correct physiological parameters and obtain accurate imaging before proceeding to the operating theater.

Background: Low serum albumin is known to be associated with mortality in sepsis, as it reflects effects of nutrition, catabolism, and edema.

Objectives: To examine the association of albumin levels with in-hospital mortality in adults with sepsis, stratified by age groups.

Methods: This nationwide retrospective cohort study comprised patients admitted with sepsis to intensive care units in seven tertiary hospitals during 2003–2011. Only patients with available serum albumin levels at hospital admission and one week after were included. Patients with an intra-abdominal source of sepsis were excluded. The association between sepsis and mortality was analyzed using multivariate logistic regression models.

Results: The study included 3967 patients (58.7% male, median age 69 years). Mean serum albumin levels were 3.1 ± 0.7 g/dl at admission and 2.4 ± 0.6 g/dl one week later. In a multivariate logistic regression model, serum albumin one week after admission was inversely associated with in-hospital mortality (odds ratio [OR] 0.64, 95% confidence interval 0.55–0.73 per 1 g/dl). In an age-stratified analysis, the association was stronger with younger age (OR 0.44 for patients aged < 45 years, 0.60 for patients aged 45–65 years, and 0.67 for patients aged > 65 years). Serum albumin on admission was not associated with in-hospital mortality.

Conclusions: The decline in serum albumin one week after admission is a stronger predictor of mortality in younger patients. Older patients might have other reasons for low serum albumin, which reflect chronic co-morbidity rather than acuity of disease.

Background: The authors describe a multifaceted cross-infection control program that was implemented to contain an epidemic of multidrug-resistant microorganisms (MRO) (carbapenem resistant Pseudomonas aeruginosa and Acinetobacter baumannii; extended spectrum β-lactamase producing Klebsiella pneumoniae, Escherichia coli, Enterobacter Cloacae, and Proteus mirabilis; and ‎methicillin-resistant Staphylococcus aureus and Candida species). 

Objectives: To assess the effect of a control program on the incidence of cross-infection with MRO.

Methods: Clinical criteria triaged patients into a high-risk wing (HRW) or a low-risk wing (LRW). Strict infection control measures were enforced; violations led to group discussions (not recorded). Frequent cultures were obtained, and use of antibiotics was limited. Each quarter, the incidence of MRO isolation was reported to all staff members. 

Results: Over a 6 year period, 1028 of 3113 patients were placed in the HRW. The incidence of MRO isolation within 48 hours of admission was 8.7% (HRW) vs. 1.91% (LRW) (P < 0.001). Acquired MRO infection density was 30.4 (HRW) vs. 15.6 (LRW) (P < 0.009). After the second year, the incidence of group discussions dropped from once or twice a month to once or twice a year.

Conclusions: These measures contained epidemics. Clinical criteria successfully triaged HRW from LRW patients and reduced cross-infection between the medical center wings. The quarterly reports of culture data were associated with improved staff compliance. MRO epidemic control with limited resources is feasible.

Background: Optimal oxygen supply is the cornerstone of the management of critically ill patients after extubation, especially in patients at high risk for extubation failure. In recent years, high flow oxygen system devices have offered an appropriate alternative to standard oxygen therapy devices such as conventional face masks and nasal prongs.

Objectives: To assess the clinical effects of high flow nasal cannula (HFNC) compared with standard oxygen face masks in Intensive Care Unit (ICU) patients after extubation.

Methods: We retrospectively analyzed 67 consecutive ventilated critical care patients in the ICU over a period of 1 year. The patients were allocated to two treatment groups: HFNC (34 patients, group 1) and non-rebreathing oxygen face mask (NRB) (33 patients, group 2). Vital respiratory and hemodynamic parameters were assessed prior to extubation and 6 hours after extubation. The primary clinical outcomes measured were improvement in oxygenation, ventilation-free days, re-intubation, ICU length of stay, and mortality.

Results: The two groups demonstrated similar hemodynamic patterns before and after extubation. The respiratory rate was slightly elevated in both groups after extubation with no differences observed between groups. There were no statistically significant clinical differences in PaCO2. However, the use of HFNC resulted in improved PaO2/FiO2 post-extubation (P < 0.05). There were more ventilator-free days in the HFNC group (P < 0.05) and fewer patients required re-intubation (1 vs. 6). There were no differences in ICU length of stay or mortality.

Conclusion: This study demonstrated better oxygenation for patients treated with HFNC compared with NRB after extubation. HFNC may be more effective than standard oxygen supply devices for oxygenation in the post-extubation period.
