<p><strong>ABSTRACT</strong></p><p><strong>Background: </strong>Critically ill patients frequently experience delirium, and antipsychotic drugs are often used to manage symptoms.</p><p><strong>Objectives: </strong>To describe the use of antipsychotic drugs and delirium screening tools in mechanically ventilated, critically ill adult patients in Canadian intensive care units (ICUs) and to identify factors associated with the use of antipsychotic drugs.</p><p><strong>Methods: </strong>Pharmacists from 51 Canadian ICUs prospectively collected data on antipsychotic use and delirium screening in all patients for whom invasive mechanical ventilation was initiated during a chosen 2-week period occurring sometime in 2008 or 2009.</p><p><strong>Results: </strong>Data were collected for a total of 712 patients, of whom 115 (16.2%) received at least one dose of an antipsychotic. The antipsychotic prescribed, the total daily dose, and the administration schedule varied across sites. Delirium screening tools, validated for use in mechanically ventilated patients and endorsed by professional society guidelines, were part of routine care in a minority of ICUs (7/51 [13.7%]), and delirium screening was documented for few patients overall (41/712 patients [5.8%]). In a multivariable analysis, administration of antipsychotics was independently associated with longer duration of mechanical ventilation (odds ratio [OR] 1.12, 95% confidence interval [CI] 1.07–1.17), daily interruption of sedation (OR 1.71, 95% CI 1.01–2.90), and use of physical restraints (OR 2.15, 95% CI 1.27–3.65).</p><p><strong>Conclusion: </strong>A minority of mechanically ventilated patients in Canadian ICUs received antipsychotic drugs, and screening for delirium with validated tools was rare.

Objectives: The value of gastric residual volume (GRV) monitoring in ventilator-associated pneumonia (VAP) has frequently been questioned in the past years. In this trial, the effect of GRV on the frequency of VAP was evaluated in critically ill patients under mechanical ventilation. Methods: This descriptive study was carried out on 150 adult patients admitted to the intensive care unit over a 14-month period, from October 2015 to January 2017. GRV was measured every three hours, and gastric intolerance was defined as GRV>250 cc. The incidence of vomiting and VAP, GRV, length of mechanical ventilation and ICU stay, APACHE II and SOFA scores, and mortality rate were noted. Results: The mean APACHEII and SOFA scores, ICU length of stay, and duration of mechanical ventilation in the GRV>250ml group were significantly higher than in the GRV≤250 ml group (P<0.05). Also, a significantly higher number of patients in the GRV>250ml group experienced infection (62.3%) and vomiting (71.7%) compared with the GRV≤250 group (P<0.01). The highest OR was observed for SOFA score >15 and APACHE II >30, which increased the risk of GVR>250 ml by 10.09 (1.01-99.97) and 8.78 (1.49-51.58), respectively. Moreover, the increase in GVR was found to be higher in the non-survivor than in the survivor group. Conclusion: Increased GRV did not result in increased rates of VAP, ICU length of stay, and mortality. Therefore, the routine measurement of GRV as an important element of the VAP prevention bundle is not recommended in critically ill patients.

Purpose: Dexmedetomidine has been shown to improve clinical outcomes in critically ill patients. However, its effect on septic patients remains controversial. Therefore, the purpose of this meta-analysis was to assess the effect of dexmedetomidine as a sedative agent for mechanically ventilated patients with sepsis.Methods: We searched PubMed, Embase, Scopus, and Cochrane Library from inception through May 2021 for randomized controlled trials that enrolled mechanically ventilated, adult septic patients comparing dexmedetomidine with other sedatives or placebo.Results: A total of nine studies involving 1,134 patients were included in our meta-analysis. The overall mortality (RR 0.97, 95%CI 0.82 to 1.13, P = 0.67, I2 = 25%), length of intensive care unit stay (MD −1.12, 95%CI −2.89 to 0.64, P = 0.21, I2 = 71%), incidence of delirium (RR 0.95, 95%CI 0.72 to 1.25, P = 0.70, I2 = 0%), and delirium free days (MD 1.76, 95%CI –0.94 to 4.47, P = 0.20, I2 = 80%) were not significantly different between dexmedetomidine and other sedative agents. Alternatively, the use of dexmedetomidine was associated with a significant reduction in the duration of mechanical ventilation (MD –0.53, 95%CI −0.85 to −0.21, P = 0.001, I2 = 0%) and inflammatory response (TNF-α: MD −5.27, 95%CI −7.99 to −2.54, P&lt;0.001, I2 = 0%; IL-1β: MD −1.25, 95%CI −1.91 to –0.59, P&lt;0.001, I2 = 0%).Conclusions: For patients with sepsis, the use of dexmedetomidine as compared with other sedative agents does not affect all-cause mortality, length of intensive care unit stay, the incidence of delirium, and delirium-free days. But the dexmedetomidine was associated with the reduced duration of mechanical ventilation and inflammatory response.

According to the “Semmelweis plan for saving health care”, „the capacity of the national network of intensive care units in Hungary is one but not the only bottleneck of emergency care at present”. In an earlier report the author showed, on the basis of data reported to the health insurance that not in a single calendar day more than 75% of beds in intensive care units were occupied. There were about 15 to 20 thousand sick days which could be considered unnecessary, because patients occupying these beds were discharged to their homes directly from the intensive care unit. This study examines the functioning of intensive care units partly at the institutional level. The author shows how the number of days using mechanical ventilation and the number of direct discharges to the home of patients have changed, and proves that those institutions where the proportion of direct discharge to home so overnursing of patients was high, the rate of mechanically ventilated patients was low.

Abstract Background: Risk factors associated with mortality in patients with coronavirus disease 2019 (COVID-19) on mechanical ventilation are still not fully elucidated. Thus, we aimed to identify patient-level factors, readily available at the bedside, associated with the risk of in-hospital mortality within 28 days from commencement of invasive mechanical ventilation (28-day IMV mortality) in patients with COVID-19. Methods Prospective observational cohort study in 148 intensive care units in the global COVID-19 Critical Care Consortium. Patients with clinically suspected or laboratory confirmed COVID-19 infection admitted to the intensive care unit (ICU) from February 2nd through December 29th, 2020, requiring IMV. No study-specific interventions were performed. Patient characteristics and clinical data were assessed upon ICU admission, the commencement of IMV and for 28 days thereafter. We primarily aimed to identify time-independent and time-dependent risk factors for 28-day IMV mortality. Results: A total of 1713 patients were included in the survival analysis, 588 patients died in hospital within 28 days of commencing IMV (34.3%). Cox-regression analysis identified associations between the hazard of 28-day IMV mortality with age (HR 1.27 per 10-year increase in age, 95% CI 1.17 to 1.37, P<0.001), PEEP upon commencement of IMV (HR 0.78 per 5-cmH2O increase, 95% CI 0.66-0.93, P=0.005). Time-dependent parameters associated with 28-day IMV mortality were serum creatinine (HR 1.30 per doubling, 95% CI 1.19-1.42, P<0.001), lactate (HR 1.16 per doubling, 95% CI 1.06-1.27 P=0.001), PaCO2 (HR 1.31 per doubling, 95% CI 1.05-1.64, P=0.015), pH (HR 0.82 per 0.1 increase, 95% CI 0.74-0.91, P<0.001), PaO2/FiO2 (HR 0.56 per doubling, 95% CI 0.50-0.62, P<0.001) and mean arterial pressure (HR 0.92 per 10 mmHg increase, 95% CI 0.88-0.97, P=0.002).Conclusions: This international study establishes that in mechanically ventilated patients with COVID-19, older age and clinically relevant variables monitored at the bedside are risk factors for 28-day IMV mortality. Further investigation is warranted to validate any causative roles these parameters might play in influencing clinical outcomes.

Background: The study aimed to investigate the out-of-range cuff pressure of endotracheal tube in mechanically ventilated patients. Methodology: This cross-sectional study was performed in Semnan, Iran in 2019. The cuff pressure was measured in patients aged over 18 years who were intubated for at least 24 hours. Out-of-range pressure was defined as a pressure of < 20 cmH2O or > 30 cmH2O. A multiple logistic regression model was used for analysis. Results: Of 222 cases, 67 (30.2%) had cuff pressure in the normal range and 155 (69.8%) were not in the normal range; 41 (18.5%) and 114 (51.4%) had low and high pressures. The two groups were not significantly different in terms of age and gender. Longer mechanical ventilation (p = 0.004) and hospitalization place (p = 0.001) were the two factors that had a relationship with the out-of-range pressure. The probability of out-of-range pressure was significantly higher in the cardiac (p = 0.001, OR = 6.91) and internal medicine (p = 0.008, OR = 4.61), compared to the emergency intensive care unit. Conclusion: The authorities should take into consideration some important factors, such as the lack of instructions in hospital units, lack of proficiency for correct measurement, deficient required facilities, and not using the facilities for regular monitoring.

AbstractAppropriate sedation in mechanically ventilated patients is important to facilitate adequate respiratory support and maintain patient safety. However, the optimal sedation protocol for children is unclear. This study assessed the effectiveness of a sedation protocol utilizing the COMFORT-B sedation scale in reducing the duration of mechanical ventilation in children. This was a nonrandomized prospective cohort study compared with a historical control. The prospective cohort study was conducted between November 2015 and August 2016 and included 58 mechanically ventilated patients admitted to the pediatric intensive care unit (PICU). All patients received protocolized sedation utilizing the COMFORT-B scale, which was assessed every 12 hours after intubation by a single assessor. The prospective data were compared with retrospective data of 58 mechanically ventilated patients who received sedation by usual care from November 2014 to August 2015. Fifty percent of 116 patients were male and the mean age was 22 months (interquartile range [IQR]: 6.6–68.4). Patients in the intervention group showed no difference in the duration of mechanical ventilation (median 4.5 [IQR: 2.2–10.5] vs. 5 [IQR: 3–8.8] days). Also, there were no significant differences in the PICU length of stay (LOS; median 7 vs. 7 days, p = 0.59) and hospital LOS (median 18 vs. 14 days, p = 0.14) between the intervention and control groups. The percentages of sedative drugs, including fentanyl, morphine, and midazolam, in each group were not statistically different. The COMFORT-B scale with protocolized sedation in mechanically ventilated pediatric patients in the PICU did not reduce the duration of mechanical ventilation compared with usual care.

Abstract Background Analgesia and sedation therapy are commonly used for critically ill patients, especially mechanically ventilated patients. From the initial nonsedation programs to deep sedation and then to on-demand sedation, the understanding of sedation therapy continues to deepen. However, according to different patient’s condition, understanding the individual patient’s depth of sedation needs remains unclear. Methods The public open source critical illness database Medical Information Mart for Intensive Care III was used in this study. Latent profile analysis was used as a clustering method to classify mechanically ventilated patients based on 36 variables. Principal component analysis dimensionality reduction was used to select the most influential variables. The ROC curve was used to evaluate the classification accuracy of the model. Results Based on 36 characteristic variables, we divided patients undergoing mechanical ventilation and sedation and analgesia into two categories with different mortality rates, then further reduced the dimensionality of the data and obtained the 9 variables that had the greatest impact on classification, most of which were ventilator parameters. According to the Richmond-ASS scores, the two phenotypes of patients had different degrees of sedation and analgesia, and the corresponding ventilator parameters were also significantly different. We divided the validation cohort into three different levels of sedation, revealing that patients with high ventilator conditions needed a deeper level of sedation, while patients with low ventilator conditions required reduction in the depth of sedation as soon as possible to promote recovery and avoid reinjury. Conclusion Through latent profile analysis and dimensionality reduction, we divided patients treated with mechanical ventilation and sedation and analgesia into two categories with different mortalities and obtained 9 variables that had the greatest impact on classification, which revealed that the depth of sedation was limited by the condition of the respiratory system.
