AbstractPatient–ventilator asynchrony (PVA) is commonly encountered during mechanical ventilation of critically ill patients. Estimates of PVA incidence vary widely. Type, risk factors, and consequences of PVA remain unclear. We aimed to measure the incidence and identify types of PVA, characterize risk factors for development, and explore the relationship between PVA and outcome among critically ill, mechanically ventilated adult patients admitted to medical, surgical, and medical-surgical intensive care units in a large academic institution staffed with varying provider training background. A single center, retrospective cohort study of all adult critically ill patients undergoing invasive mechanical ventilation for ≥ 12 h. A total of 676 patients who underwent 696 episodes of mechanical ventilation were included. Overall PVA occurred in 170 (24%) episodes. Double triggering 92(13%) was most common, followed by flow starvation 73(10%). A history of smoking, and pneumonia, sepsis, or ARDS were risk factors for overall PVA and double triggering (all P < 0.05). Compared with volume targeted ventilation, pressure targeted ventilation decreased the occurrence of events (all P < 0.01). During volume controlled synchronized intermittent mandatory ventilation and pressure targeted ventilation, ventilator settings were associated with the incidence of overall PVA. The number of overall PVA, as well as double triggering and flow starvation specifically, were associated with worse outcomes and fewer hospital-free days (all P < 0.01). Double triggering and flow starvation are the most common PVA among critically ill, mechanically ventilated patients. Overall incidence as well as double triggering and flow starvation PVA specifically, portend worse outcome.

Abstract Background To produce statements based on the available evidence and an expert consensus (as members of the Lung Ultrasound Working Group of the Italian Society of Analgesia, Anesthesia, Resuscitation, and Intensive Care, SIAARTI) on the use of lung ultrasound for the management of patients with COVID-19 admitted to the intensive care unit. Methods A modified Delphi method was applied by a panel of anesthesiologists and intensive care physicians expert in the use of lung ultrasound in COVID-19 intensive critically ill patients to reach a consensus on ten clinical questions concerning the role of lung ultrasound in the following: COVID-19 diagnosis and monitoring (with and without invasive mechanical ventilation), positive end expiratory pressure titration, the use of prone position, the early diagnosis of pneumothorax- or ventilator-associated pneumonia, the process of weaning from invasive mechanical ventilation, and the need for radiologic chest imaging. Results A total of 20 statements were produced by the panel. Agreement was reached on 18 out of 20 statements (scoring 7–9; “appropriate”) in the first round of voting, while 2 statements required a second round for agreement to be reached. At the end of the two Delphi rounds, the median score for the 20 statements was 8.5 [IQR 8.9], and the agreement percentage was 100%. Conclusion The Lung Ultrasound Working Group of the Italian Society of Analgesia, Anesthesia, Resuscitation, and Intensive Care produced 20 consensus statements on the use of lung ultrasound in COVID-19 patients admitted to the ICU. This expert consensus strongly suggests integrating lung ultrasound findings in the clinical management of critically ill COVID-19 patients.

Aim To assess the feasibility, tolerance and effectiveness of enteral nutrition in critically ill patients receiving invasive mechanical ventilation in the prone position for severe Acute Respiratory Distress Syndrome (ARDS). Methods Prospective observational study conducted in a multidisciplinary critical care unit of a tertiary care hospital from January 2013 until July 2015. All patients with ARDS who received invasive mechanical ventilation in prone position during the study period were included. Patients’ demographics, severity of illness (Acute Physiology and Chronic Health Evaluation (APACHE II) score), baseline markers of nutritional status (subjective global assessment (SGA) and body mass index), details of nutrition delivery during prone and supine hours and outcomes (Length of stay and discharge status) were recorded. Results Fifty-one patients met inclusion criteria out of whom four patients were excluded from analysis since they did not receive any enteral nutrition due to severe hemodynamic instability. The mean age of patients was 46.4 ± 12.9 years, with male:female ratio of 7:3. On admission, SGA revealed moderate malnutrition in 51% of patients and the mean APACHE II score was 26.8 ± 9.2. The average duration of prone ventilation per patient was 60.2 ± 30.7 h. All patients received continuous nasogastric/orogastric feeds. The mean calories (kcal/kg/day) and protein (g/kg/day) prescribed in the supine position were 24.5 ± 3.8 and 1.1 ± 0.2 while the mean calories and protein prescribed in prone position were 23.5 ± 3.6 and 1.1 ± 0.2, respectively. Percentage of prescribed calories received by patients in supine position was similar to that in prone position (83.2% vs. 79.6%; P = 0.12). Patients received a higher percentage of prescribed protein in supine compared to prone position (80.8% vs. 75%, P = 0.02). The proportion of patients who received at least 75% of the caloric and protein goals was 37 (78.7%) and 37 (78.7%) in supine and 32 (68.1%) and 21 (44.6%) in prone position. Conclusion In critically ill patients receiving invasive mechanical ventilation in the prone position, enteral nutrition with nasogastric/orogastric feeding is feasible and well tolerated. Nutritional delivery of calories and proteins in prone position is comparable to that in supine position.

Abstract Background: Mechanical insufflation-exsufflation (MI-E) is a non-invasive technique performed through the CoughAssist In-Exsufflator to simulate cough and remove mucus from proximal airways. To date, the effects of MI-E on critically ill patients on invasive mechanical ventilation (MV) are not fully elucidated. The purpose of this study was to compare the efficacy and safety of MI-E combined or not to manual chest physiotherapy (CPT) in these patients.Methods: This cross-over clinical study enrolled consecutive patients who were sedated, intubated and on MV > 48h with expected maintenance of these criteria > 24h. Over a 24-hour period, patients randomly performed two sessions of manual CPT with or without additional MI-E before tracheal suctioning. Following each procedure, volume of retrieved mucus (ml) was assessed to evaluate efficacy. We evaluated respiratory flows, pulmonary mechanics and hemodynamics before, during, and after treatment. In addition, safety of MI-E was also appraised.Results: 26 patients were included. In comparison to CPT, mucus volume retrieved was significantly higher during CPT+MI-E (0.42 [0; 1.39] ml vs 2.29 [1; 4.67] ml; p < 0.001). The respiratory system compliance immediately improved from pre and post Crs values in CPT+MI-E group (55.7 ml/cmH2O [38.3; 67.4] vs. 68.6ml/cmH2O [47.8;94.9]; p<0.001). Although, such increase was not significantly different between CPT and CPT+MI-E group (p=0.057). Heart rate significantly increased in both groups (p < 0.005) immediately after each intervention. Additionally, a significant impact on oxygenation was observed in the CPT+MI-E group when comparing the baseline values with the values one-hour post-intervention (p<0.05). Finally, several transitory hemodynamic variations occurred during both interventions, but these were non-significant and considered clinically irrelevant.Conclusion: In mechanically ventilated patients, MI-E increases the amount of secretions that can be retrieved post-CPT, without causing clinically significant adverse events.Clinical Trials Registration Number: NCT03316079 (24/11/2015; retrospectively registered)

Background and Objectives: The aim of this study was to investigate the association between obesity and 28-day mortality, duration of invasive mechanical ventilation and length of stay at the Intensive Care Unit (ICU) and hospital in patients admitted to the ICU for SARS-CoV-2 pneumonia. Materials and Methods: This was a retrospective observational cohort study in patients admitted to the ICU for SARS-CoV-2 pneumonia, in a single Dutch center. The association between obesity (body mass index > 30 kg/m2) and 28-day mortality, duration of invasive mechanical ventilation and length of ICU and hospital stay was investigated. Results: In 121 critically ill patients, pneumonia due to SARS-CoV-2 was confirmed by RT-PCR. Forty-eight patients had obesity (33.5%). The 28-day all-cause mortality was 28.1%. Patients with obesity had no significant difference in 28-day survival in Kaplan–Meier curves (log rank p 0.545) compared with patients without obesity. Obesity made no significant contribution in a multivariate Cox regression model for prediction of 28-day mortality (p = 0.124), but age and the Sequential Organ Failure Assessment (SOFA) score were significant independent factors (p < 0.001 and 0.002, respectively). No statistically significant correlation was observed between obesity and duration of invasive mechanical ventilation and length of ICU and hospital stay. Conclusion: One-third of the patients admitted to the ICU for SARS-CoV-2 pneumonia had obesity. The present study showed no relationship between obesity and 28-day mortality, duration of invasive mechanical ventilation, ICU and hospital length of stay. Further studies are needed to substantiate these findings.

Abstract Introduction Timely recognition of the return to spontaneous ventilation is essential for reducing costs, morbidity, and mortality. Delays in both removing invasive ventilatory support and excessively early removal are correlated with complications that vary according to the severity of the underlying disease. Several weaning indices and predictors were studied in an attempt to evaluate the outcome of removing ventilatory support. However, none of them have yet presented good results in discriminating the outcome of extubation, even those most used in clinical practices. Aim The aim of this study is to validate the modified integrative weaning index (mIWI) as a reliable weaning index in comparison to the conventional weaning indices in the weaning of critically ill patients from invasive mechanical ventilation. Patients Four hundred patients, above the age of 18 years, on mechanical ventilation for more than 48 hours through an endotracheal tube for any cause were randomly assigned to this study. Methods patients ready to be weaned were assessed using mIWI and conventional indices and monitored for 48 hours. The performance of the indices were assessed in both successful and unsuccessful groups. Results The performance of the mIWI was not significantly superior to the conventional weaning indices in predicting weaning success or failure than the traditional weaning indices. The cut-off value for the predicting successful weaning from mechanical ventilation for the mIWI was higher than suggested by the original study and yet in agreement with some other studies. The cut-off value for the mIWI is higher in patients above the age of 60 years. Conclusion The results of the study revealed that the mIWI is a good predictor of weaning from mechanical ventilation and assessment of pulmonary mechanics and is not significantly superior to the traditional weaning indices, yet is not a good predictor for extubation success.
