The Effect of Stress Ulcer Prophylaxis on Ventilator-Associated Pneumonia Incidence in the Intensive Care Unit

Ventilator-associated pneumonia (VAP) is one of the most common causes of nosocomial infections in the intensive care unit. Mechanically ventilated patients are at risk for upper gastrointestinal (GI) bleeding. It has been shown in previous studies that acid suppression therapy used for GI prophylaxis may cause the development of bacterial pneumonia. The aim of this review is to evaluate the effect of stress ulcer prophylaxis on VAP incidence in the intensive care unit. (Yogun Bakim Derg 2015; 6: 10-2

Evaluation of whole blood thiamine pyrophosphate concentrations in critically ill patients receiving chronic diuretic therapy prior to admission to Turkish intensive care units: A pragmatic, multicenter, prospective study

Background/Objectives: Thiamine plays a pivotal role in energy metabolism. The aim of the study was to deter-mine serial whole blood TPP concentrations in critically ill patients receiving chronic diuretic treatment before ICU admission and to correlate TPP levels with clinically determined serum phosphorus concentrations.Subjects/Methods: This observational study was performed in 15 medical ICUs. Serial whole blood TPP concen-trations were measured by HPLC at baseline and at days 2, 5 and 10 after ICU admission. Results: A total of 221 participants were included. Of these, 18% demonstrated low TPP concentrations upon admission to the ICU, while 26% of participants demonstrated low levels at some point during the 10-day study period. Hypophosphatemia was detected in 30% of participants at some point during the 10-day period of observation. TPP levels were significantly and positively correlated with serum phosphorus levels at each time point (P < 0.05 for all).Conclusions: Our results show that 18% of these critically ill patients exhibited low whole blood TPP concen-trations on ICU admission and 26% had low levels during the initial 10 ICU days, respectively. The modest correlation between TPP and phosphorus concentrations suggests a possible association due to a refeeding effect in ICU patients requiring chronic diuretic therapy

Nutritional practices in medical intensive care units: Multicenter, one-day point prevalence study Pratiques nutritionnelles dans les unités de soins intensifs médicaux : étude de prévalence ponctuelle multicentrique sur une journée

Background/Aim: Nutritional planning is an important aspect of Intensive Care Unit (ICU) care. The present study aimed to evaluate the nutritional practices adopted in medical ICUs in Turkiye and to investigate their compliance with current international guidelines. Methods: This multicenter, cross-sectional study was performed on a predetermined study date. Centers were required to fill three groups of questionnaires: One on ICU characteristics and facilities, one on patients included, and one on outcomes of patients. Forms on patients had questions on demographics and their nutritional status. Results: A total of 12 sites participated and 132 patients were recorded in the study and 109 patients were included in analyses. The median age was 72 [57–83] years and 55 (50%) of them was female. The median APACHE II score was 23 [18–29], median SOFA score was 6 [4–9] and median BMI was 25.32 [21.22–29.38]. More than 50% of patients were fed enterally; for most, it was started within the first 24 hours of admission. On the study day, the median energy intake of the patients during the last 24 hours was 21.62 [15.9–27.3] kcal/kg and the median amount of protein intake was 1.02 [0.7–1.3] g/kg, representing 83.1% and 78.9% of the targets, respectively. A total of 64 (58.7%) patients were alive on the 28th day of the study, of them 23 (21.1% of all patients) were still in the ICU. Conclusion: Nutrition therapy in medical ICUs was initiated early after ICU admission, the enteral route was preferred and target calories were calculated using weight-based formulas. These results suggest that multi-dimensional planning of critical care management of patients by intensivists may provide better nutritional care for the critically ill

Can we predict patients that will not benefit from invasive mechanical ventilation? A novel scoring system in intensive care: the IMV mortality prediction score (IMPRES)

KUCUK, Ahmet Oguzhan/0000-0002-6993-0519; Kirakli, Cenk/0000-0001-6013-7330; KUCUK, Mehtap PEHLIVANLAR/0000-0003-2247-4074; Aksoy, Iskender/0000-0002-4426-3342WOS: 000504051300010PubMed: 31655511Background/aim: The present study aimed to define the clinical and laboratory criteria for predicting patients that will not benefit from invasive mechanical ventilation (IMV) treatment and determine the prediction of mortality and prognosis of these critical ill patients. Materials and methods: The study was designed as an observational, multicenter, prospective, and cross-sectional clinical study. It was conducted by 75 researchers at 41 centers in intensive care units (ICUs) located in various geographical areas of Turkey. It included a total of 1463 ICU patients who were receiving invasive mechanical ventilation (IMV) treatment. A total of 158 parameters were examined via logistic regression analysis to identify independent risk factors for mortality; using these data, the IMV Mortality Prediction Score (IMPRES) scoring system was developed. Results: The following cut-off scores were used to indicate mortality risk: 8, very high risk. There was a 26.8% mortality rate among the 254 patients who had a total IMPRES score of lower than 2. The mortality rate was 93.3% for patients with total 1M PRES scores of greater than 8 (P < 0.001). Conclusion: The present study included a large number of patients from various geographical areas of the country who were admitted to various types of ICUs, had diverse diagnoses and comorbidities, were intubated with various indications in either urgent or elective settings, and were followed by physicians from various specialties. Therefore, our data are more general and can be applied to a broader population. This study devised a new scoring system for decision-making for critically ill patients as to whether they need to be intubated or not and presents a rapid and accurate prediction of mortality and prognosis prior to ICU admission using simple clinical data

Weaning from mechanical ventilation in intensive care units across 50 countries (WEAN SAFE): a multicentre, prospective, observational cohort study

Background: Current management practices and outcomes in weaning from invasive mechanical ventilation are poorly understood. We aimed to describe the epidemiology, management, timings, risk for failure, and outcomes of weaning in patients requiring at least 2 days of invasive mechanical ventilation. Methods: WEAN SAFE was an international, multicentre, prospective, observational cohort study done in 481 intensive care units in 50 countries. Eligible participants were older than 16 years, admitted to a participating intensive care unit, and receiving mechanical ventilation for 2 calendar days or longer. We defined weaning initiation as the first attempt to separate a patient from the ventilator, successful weaning as no reintubation or death within 7 days of extubation, and weaning eligibility criteria based on positive end-expiratory pressure, fractional concentration of oxygen in inspired air, and vasopressors. The primary outcome was the proportion of patients successfully weaned at 90 days. Key secondary outcomes included weaning duration, timing of weaning events, factors associated with weaning delay and weaning failure, and hospital outcomes. This study is registered with ClinicalTrials.gov, NCT03255109. Findings: Between Oct 4, 2017, and June 25, 2018, 10 232 patients were screened for eligibility, of whom 5869 were enrolled. 4523 (77·1%) patients underwent at least one separation attempt and 3817 (65·0%) patients were successfully weaned from ventilation at day 90. 237 (4·0%) patients were transferred before any separation attempt, 153 (2·6%) were transferred after at least one separation attempt and not successfully weaned, and 1662 (28·3%) died while invasively ventilated. The median time from fulfilling weaning eligibility criteria to first separation attempt was 1 day (IQR 0-4), and 1013 (22·4%) patients had a delay in initiating first separation of 5 or more days. Of the 4523 (77·1%) patients with separation attempts, 2927 (64·7%) had a short wean (≤1 day), 457 (10·1%) had intermediate weaning (2-6 days), 433 (9·6%) required prolonged weaning (≥7 days), and 706 (15·6%) had weaning failure. Higher sedation scores were independently associated with delayed initiation of weaning. Delayed initiation of weaning and higher sedation scores were independently associated with weaning failure. 1742 (31·8%) of 5479 patients died in the intensive care unit and 2095 (38·3%) of 5465 patients died in hospital. Interpretation: In critically ill patients receiving at least 2 days of invasive mechanical ventilation, only 65% were weaned at 90 days. A better understanding of factors that delay the weaning process, such as delays in weaning initiation or excessive sedation levels, might improve weaning success rates.
