RESUMEN
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.

INTRODUCTION: One-year mortality following hip fractures increases steeply with age, from 2% in the 60- to 69-year-old population up to 28% in the oldest old (older than 90 years). Of the various factors that contribute to hip fractures, atrial fibrillation (AF) is an independent risk factor at any age. OBJECTIVE: The objective of this study was to assess the association of AF with mortality among the oldest old with hip fractures. METHOD: This is a retrospective cohort study of 701 persons above age 90 years who underwent orthopedic repair for a hip fracture during 2000-2018. Of them, 218 (31%) had AF at hospital admission. The primary outcome was survival following surgery. We compared patient characteristics and 30-day, 180-day, 1-year, and 3-year survival between patients with and without AF. RESULTS: The adjusted odds ratio for 30-day postoperative mortality for those with AF versus without AF group was 1.03 (95% confidence interval [CI] 0.63-1.66). Survival estimates were higher among those without AF than with AF at 180 days postoperative: 0.85 (95% CI 0.82-0.89) versus 0.68 (95% CI 0.61-0.74), p < 0.001; at 1 year postoperative: 0.68 (95% CI 0.63-0.72) versus 0.48 (95% CI 0.42-0.55), p < 0.001; and at 3 years postoperative: 0.47 (95% CI 0.42-0.52) versus 0.28 (95% CI 0.27-0.34), p < 0.001. CONCLUSIONS: Among individuals aged >90 years, operated for hip fractures, mortality was similar for those with and without AF at 30 days postoperative. However, the survival curves diverged sharply after 180 days. Our findings suggest that AF is not an immediate surgical risk factor, but rather confers increased long-term risk in this population.

PURPOSE: To estimate the change in intra-abdominal pressure (IAP) among critically ill patient who were left with open abdomen and temporary abdominal closure after laparotomy, during the first 48 h after admission. METHODS: A cohort study in a single ICU in a tertiary care hospital. All adult patients admitted to the ICU after emergent laparotomy for acute abdomen or trauma, who were left with temporary abdominal closure (TAC), were included. Patients were followed up to 48 h. IAP was routinely measured at 0, 6, 12, 24, and 48 h after admission to ICU. RESULTS: Thirty-nine patients were included, 34 were operated due to acute abdomen and 5 due to abdominal trauma. Seventeen patients were treated with skin closure, 13 with Bogota bag, and 9 with negative pressure wound therapy (NPWT). Eleven patients (28.2%) had IAP of 15 mmHg or above at time 0, (mean pressure 19.0 ± 3.0 mmHg), and it dropped to 12 ± 4 mmHg within 48 h (p < 0.01). Reduction in lactate level (2.4 ± 1.0 to 1.2 ± 0.2 mmol/L, p < 0.01) and increase in PaO2/FiO2 ratio (163 ± 34 to 231 ± 83, p = 0.03) were observed as well after 48 h. CONCLUSIONS: This is the first large report of IAP in open abdomen. Elevated IAP may be measured in open abdomen and may subsequently relieve after 48 h.

INTRODUCTION: In contrast to an emergency department of thoracotomy (EDT), an urgent thoracotomy (UT) is defined as a surgical thoracic intervention performed in the operating room within the first 48 hours of the patient's intensive care unit (ICU) stay. The factors affecting survival after UT are not fully understood. In this study, we retrospectively analyzed the clinical data and outcome of patients with blunt and penetrating chest injuries who underwent UT. METHODS: All adult patients who had blunt or penetrating chest trauma and who underwent UT, were included in the study. All data were collected from the patients' hospital and ICU records. Forty-five patients with thoracic injuries who underwent UT during the first 48 hours of ICU stay were analyzed. Of these, 25 had penetrating chest injuries, and 20 had blunt thoracic injuries. Of the penetrating injuries, 16 were stab wounds, and 9 were gunshot wounds. RESULTS: Overall ICU mortality was 29% (n = 13) and was significantly higher in the blunt chest trauma group than in the penetrating trauma group (45% vs 16%; p = 0.04). Lung parenchyma injuries (lacerations and contusions) were the most common intraoperative findings in both groups. The following independent predictors of in-hospital mortality were found: an Injury Severity Score (ISS) of >40; an Acute Physiology and Chronic Evaluation II (APACHE II) score of >30; prolonged duration of UT; low body temperature on admission to the ED; abnormal arterial blood lactate, bicarbonate, and pH at the end of UT; and use of vasopressors during the first 24 hours of ICU stay. CONCLUSION: Mortality after UT was higher in patients with blunt chest trauma. The UT should be performed in both penetrating and blunt chest trauma as quickly as possible and should be limited to damage control. It also emerges that acidosis and hypothermia in chest trauma patients need to be treated extremely aggressively before, during, and after UT.

OBJECTIVES: To evaluate whether a single-operator ultrasound-guided, right-sided, central venous catheter insertion verifies proper placement and shortens time to catheter utilization. DESIGN: Prospective observational study with historical controls. SETTING: Adult ICUs. PATIENTS: Sixty-four consecutive patients undergoing ultrasound-assisted right-sided central venous catheterization compared with 92 serial historic controls who had unassisted central catheter insertion at the same sites. INTERVENTIONS: Subcostal transthoracic echocardiography during catheter insertion. MEASUREMENTS AND MAIN RESULTS: The primary outcome was the correct placement of the catheter tip determined by postprocedural chest radiography. The subclavian site was used in 41 patients (64%) (inserted without ultrasound guidance) in the ultrasound-assisted group and 62 (67%) in the control group, whereas the jugular vein was used in the remaining patients. The tip was accurately positioned in 59 of 68 patients (86.7%) in the ultrasound-assisted group compared with 51 of 94 (54.8%) in the control group (p < 0.001). The median time from end of the procedure to catheter utilization after chest radiography approval was 2.4 hours. CONCLUSIONS: A single-operator ultrasound-guided central venous catheter insertion is effective in verifying proper tip placement and shortens time to catheter utilization.

PURPOSE: Acinetobacter baumannii is a multidrug resistant (MDR), gram-negative bacterium commonly implicated in ventilator-associated pneumonia (VAP) in critically ill patients. Patients in the intensive care unit (ICU) with VAP often subsequently develop A baumannii bacteremia, which may significantly worsen outcomes. MATERIALS AND METHODS: In this study, we retrospectively reviewed the clinical and laboratory records of 129 ICU patients spanning 6 years with MDR A baumannii VAP; 46 (35%) of these patients had concomitant MDR A baumannii bacteremia. RESULTS: The ICU mortality rate was higher in patients with VAP having A baumannii bacteremia compared to nonbacteremic patients (32.4% vs 9.6% respectively, P < .005). Age >65 years, an Acute Physiology and Chronic Health Evaluation II (APACHE-II) score higher than 20, a Sequential Organ Failure Assessment (SOFA) score higher than 7 on the day of bacteremia, and the presence of comorbid disease (chronic obstructive pulmonary disease [COPD] and chronic renal failure) were found to be independent risk factors for in-hospital mortality in this population. Multidrug resistant A baumannii was not an independent risk factor for mortality. CONCLUSION: Although the presence of comorbid diseases (COPD and chronic renal failure) and severity of disease (APACHE > 20 and SOFA >7) were found to be independent risk factors for ICU mortality, MDR A baumannii bacteremia was not an independent risk factor for mortality in our critically ill population.

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 ß-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.

INTRODUCTION: Sepsis and septic shock continue to be syndromes that carry a high mortality rate worldwide. Early aggressive fluid and vasopressor support have resulted in significant improvement in patient outcomes. The prognostic clinical significance of a positive fluid balance in septic intensive care unit (ICU) patients remains undetermined. METHODS: We collected data from 297 septic patients hospitalized in our general and medical ICUs at Soroka Medical Center between January 2005 and June 2011 and divided the 4 study groups into the following 4 fluid balances: group 1, patients with fluid balance at discharge from ICU (FBD) less than 10 L; group 2, patients with an FBD of 10 to 20 L; group 3, patients with an FBD of 20 to 30 L; and group 4, patients with FBD in excess of 30 L. RESULTS: The ICU and in-hospital mortality rate was also significantly higher in groups 2 to 4 as compared with group 1 (P < .001 for both ICU and in-hospital mortality). The positive cumulative FBD was found to be an independent predictor of ICU mortality (odds ratio [OR], 1.04; 95% confidence interval [CI], 1.02-1.06; P < .001; Table 3) and in-hospital mortality (OR, 1.06; 95% CI, 1.03-1.08; P < .001; Table 5) and also to constitute a risk factor for new organ system dysfunction at hospital discharge (OR, 1.01; 95% CI, 1.01-1.013; P < .001; Table 6) in critically ill patients with severe sepsis/septic shock. CONCLUSIONS: Although it is a monocentric retrospective study, we suggest that positive cumulative fluid balance is one of the major factors that can predict the clinical outcome of critically ill patients during their ICU stay and after their discharge from the ICU.

BACKGROUND: Ventilator associated pneumonia (VAPI is a common complication leading to lengthier hospitalizations and higher mortality. Prompt adequate initial antibiotic coverage is the crucial issue affecting survival. Currently, there is no gold standard diagnostic test. No conclusive data regarding the benefit of bronchoscopy exists in the literature reviewed. AIM: This study aims to evaluate the change of prognosis for patients who developed VAP, following a positive culture from bronchoalveolar lavage (BAL). DESIGN: This is a retrospective cohort study. SETTING: General intensive care unit in a tertiary university healthcare center. PARTICIPANTS: All patients who were admitted to Surgical ICU and developed VAP and who then underwent diagnostic bronchoscopy with BAL between the period 01/02/2007 - 31/02/2011. MEASUREMENTS AND RESULTS: A total of 66 patients who were admitted to the ICU, developed VAP and underwent bronchoscopy while ventilated; 30 patients were excluded. The positive BAL culture group was compared to the negative BAL culture group; there was no difference between demographic and clinical characteristics, mortality rates (for 30 days) or therapy change between the two groups. No complications were reported regarding the bronchoscopy procedure. CONCLUSIONS: Our findings demonstrate that performing y a diagnostic bronchoscopy with BAL does not improve the prognosis of patients with VAP. Furthermore, expanded prospective studies will be needed to conclude regarding its benefit in diagnosis and subsequent rectifying of therapy.

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 reintubation (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.

CONTEXT-Most reports on organ donation have been related to the importance of support for families, explanations of brain death, and the appeal for organ donation. In contrast, no reports have addressed organ donation from the perspective of intervention in cases of "sudden mourning" and the practical aspects of how to facilitate donation in such cases. OBJECTIVE-To develop a specific strategy for professional intervention in cases of imminent death to bring the family to a state of cognitive and emotional preparedness that will enable them to accept the tragic news, donate organs, and then take leave of the deceased. METHOD-The strategy presented here was developed on the basis of the records of donor coordinators who documented their interaction with families; consultations with professionals in the fields of marketing, persuasion, and negotiating; research conducted on families who did or did not donate organs; and statements made by family members of donors in focus and support groups in more than 10 years. RESULTS-The strategic approach includes early-stage rules such as staff self-awareness, and then later, critical stages of the process that take place before and at the time of determination of brain death: preparation for and the notification of death itself and the request for organ donation, including persuasion skills, coping with resistance and expressions of anger, and physical leave-taking from the deceased. CONCLUSIONS-The flexible, strategic approach set out here is designed to maximize the chances of procuring organ donation while protecting the family's rights and welfare.

BACKGROUND: Lactic dehydrogenase reflects target organ damage, and is associated with mortality in patients with infectious diseases. OBJECTIVE: The purpose of this study was to examine associations of serum lactic dehydrogenase levels with mortality, target organ damage and length of hospital stay in adults with pulmonary and non-pulmonary infections. METHODS: This nationwide retrospective cohort study comprised patients admitted with infections, to medical and surgical departments in eight tertiary hospitals during 2001-2020. Patients with available serum lactic dehydrogenase levels on admission and one week after were included, and stratified by the source of their infection: pulmonary vs. non-pulmonary. Associations of lactic dehydrogenase levels with mortality and target organ damage were analyzed using multivariable logistic regression models. Quantile regression was used for multivariable analysis of the median length of stay. RESULTS: The study included 103,050 patients (45.4% male, median age: 69 years); 44,491 (43.1%) had pulmonary infections. The median serum lactic dehydrogenase levels on admission were higher in patients with pulmonary than non-pulmonary infections (418 vs. 385 units per liter (U/L), p<0.001). In a multivariable logistic regression model, elevated serum lactic dehydrogenase levels (480-700 U/L, 700-900 U/L and >900 U/L), compared with <480 U/L, were associated with in-hospital mortality (OR = 1.81, 2.85 and 3.69, respectively) and target organ damage (OR = 1.19, 1.51 and 1.80, respectively). The median stay increased with increasing elevated lactic dehydrogenase levels (+0.3, +0.5 and +0.4 days, respectively). Among patients with lactic dehydrogenase levels >900 U/L, mortality, but none of the other examined outcomes, was greater among those with pulmonary than non-pulmonary infections. CONCLUSIONS: Among hospitalized patients with infectious diseases, lactic dehydrogenase levels were associated with mortality and target organ damage, and were similar in patients with pulmonary and non-pulmonary infections. Among patients with lactic dehydrogenase levels >900 U/L, mortality was prominently higher among those with pulmonary than non-pulmonary infections.

BACKGROUND: Beta-blockers, mainly propranalol, are usually administered to control heart rate in patients with thyrotoxicosis, especially when congestive heart failure presents. However, when thyrotoxicosis is not controlled, heart rate may be difficult to control even with maximal doses of propranolol. This presentation alerts physicians to the possibility of using ivabradine, a selective inhibitor of the sinoatrial pacemaker, for the control of heart rate. CASE PRESENTATION: We present a 37-year-old woman with thyrotoxicosis and congestive heart failure whose heart rate was not controlled with a maximal dose of beta blockers during a thyroid storm. The addition of ivabradine, a selective inhibitor of the sinoatrial pacemaker, controlled her heart rate within 48 hours. CONCLUSION: Ivabradine should be considered in patients with thyrotoxicosis, including those with heart failure, in whom beta blockers are insufficient to control heart rate.

Critically ill patients with sepsis often require packed cell transfusions (PCT). However, PCT may affect white blood cell (WBC) counts. We conducted a population-based retrospective cohort study to trace changes in WBC count following PCT in critically ill patients with sepsis. We included 962 patients who received one unit of PCT while hospitalized in a general intensive care unit, and 994 matched patients who did not receive PCT. We calculated the mean values of WBC count for the 24 h before and 24 h after PCT. Multivariable analyses using a mixed linear regression model were performed. The mean WBC count decreased in both groups, but more in the non-PCT group (from 13.9 × 109/L to 12.2 × 109/L versus 13.9 × 109/L to 12.8 × 109/L). A linear regression model showed a mean decrease of 0.45 × 109/L in WBC count over the 24 h following the start of PCT. Every 1.0 × 109/L increase in the WBC count prior to PCT administration showed a corresponding decrease of 0.19 × 109/L in the final WBC count. In conclusion, among critically ill patients with sepsis, PCT causes only mild and clinically non-prominent changes in WBC count.
RESUMEN
ABSTRACT: Background : Critically ill patients with sepsis often require packed cell transfusions (PCTs). Packed cell transfusion causes changes in body's core temperature. Objective : To trace the course and amplitude of body core temperature after PCT in adults with sepsis. Methods : We conducted a population-based retrospective cohort study of patients with sepsis who received one unit of PCT during their hospitalization in a general intensive care unit during 2000-2019. A control group was established by matching each of these patients to a patient who did not receive PCT. We calculated the mean values of urinary bladder temperature for the 24 h before and 24 h after PCT. To evaluate the effect of PCT on body core temperature, multivariable analyses using a mixed linear regression model were performed. Results : The study comprised 1,100 patients who received one unit of PCT and 1,100 matched patients. The mean temperature before PCT was 37.3°C. Immediately from initiation of PCT, body temperature decreased, to a minimum of 37.0°C. During the 24 subsequent hours, the temperature increased gradually and consistently, until a peak temperature of 37.4°C. In a linear regression model, body core temperature increased by a mean 0.06°C in the first 24 h after PCT and decreased by a mean 0.65°C for every 1.0°C increase before PCT. Conclusions : Among critically ill patients with sepsis, PCT itself causes only mild and clinically insignificant temperature changes. Thus, significant changes in core temperature during the 24 h after PCT may indicate an unusual clinical event that requires clinicians' immediate attention.

OBJECTIVE: To estimate in-hospital, 1-yr, and long-term mortality and to assess time trends in incidence and outcomes of sepsis admissions in the intensive care unit. DESIGN: A population-based, multicenter, retrospective cohort study. PATIENTS: Patients hospitalized with sepsis in the intensive care unit in seven general hospitals in Israel during 2002-2008. INTERVENTIONS: None. MEASUREMENTS: Survival data were collected and analyzed according to demographic and background clinical characteristics, as well as features of the sepsis episode, using Kaplan-Meier approach for long-term survival. MAIN RESULTS: A total of 5,155 patients were included in the cohort (median age: 70, 56.3% males; median Charlson comorbidity index: 4). The mean number of intensive care unit admissions per month increased over time, while no change in in-hospital mortality was observed. The proportion of patients surviving to hospital discharge was 43.9%. The 1-, 2-, 5-, and 8-yr survival rates were 33.0%, 29.8%, 23.3%, and 19.8%, respectively. Mortality was higher in older patients, patients with a higher Charlson comorbidity index, and those with multiorgan failure, and similar in males and females. One-year age-standardized mortality ratio was 21-fold higher than expected, based on the general population rates. CONCLUSIONS: Mortality following intensive care unit sepsis admission remains high and is correlated with underlying patients' characteristics, including age, comorbidities, and the number of failing organ systems.
