Flow-controlled ventilation (FCV) enables precise determination of dynamic compliance due to a continuous flow coupled with direct tracheal pressure measurement. Thus, pressure settings can be adjusted accordingly in an individualised approach. ⋯ In this porcine study FCV maintained normocapnia during OLV, whereas permissive hypercapnia had to be accepted in PCV despite a substantially higher minute volume. Reducing exposure of the lungs to mechanical power applied by the ventilator in FCV offers a possible advantage for this mode of ventilation in terms of lung protection.

Recent studies reported that children on mechanical ventilation who were managed with an analgosedation approach and standardized extubation readiness testing experienced better outcomes, including decreased delirium and invasive mechanical ventilation duration. ⋯ A multidisciplinary, bundled benzodiazepine-sparing analgosedation and extubation readiness testing approach resulted in a reduction in mechanical ventilation duration and benzodiazepine exposure without impacting key balancing measures. External validity needs to be evaluated in similar centers and consensus on best practices developed.

Factors Associated With Mechanical Ventilation Duration in Pediatric Burn Patients in a Regional Burn Center in the United States.
Among burned children who arrive at a burn center and require invasive mechanical ventilation (IMV), some may have prolonged IMV needs. This has implications for patient-centered outcomes as well as triage and resource allocation decisions. Our objective was to identify factors associated with the duration of mechanical ventilation in pediatric patients with acute burn injury in this setting. ⋯ The presence of inhalational injury and burns to the head and neck region were associated with a longer duration of mechanical ventilation. Older age and male gender were associated with a shorter duration of mechanical ventilation. These factors should help clinicians better estimate a burned child's expected trajectory and resource-intensive needs upon arrival to a burn center.

Fentanyl is selected to manage pain in critical care patients on mechanical ventilation in the intensive care unit (ICU). However, the usefulness of fentanyl compared with other opioids is unknown. This study examined the evidence for using fentanyl to improve the clinical outcomes of ICU patients, using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. ⋯ Although fentanyl is a frequently administered opioid in the ICU, patients' outcomes are not different between fentanyl use and use of other opioids. However, the GRADE evaluation provides little certainty to support the results of this systematic review. Therefore, further large RCTs are required to confirm our conclusions.

Given the long ventilation times of patients with COVID-19 that can cause atrophy and contractile weakness of respiratory muscle fibers, assessment of changes at the bedside would be interesting. As such, the aim of this study was to determine the evolution of respiratory muscle thickness assessed by ultrasound. ⋯ In ventilated subjects with COVID-19, overall no change in diaphragm thickness was observed. Subjects with decreased or unchanged thickness had a longer ventilation time than those with increased thickness. NMBA use was associated with decreased thickness. Rectus muscle thickness did not change over time, whereas lateral abdominal muscle thickness decreased but this change was not statistically significant.
