ARDS is severe form of respiratory failure with significant impact on the morbidity and mortality of critical care patients. Epidemiological data are crucial for evaluating the efficacy of therapeutic interventions, designing studies, and optimizing resource distribution. The goal of this review is to present general aspects of mortality data published over the past decades. A systematic search of the MEDLINE/PubMed was performed. The articles were divided according to their methodology, type of reported mortality, and time. The main outcome was mortality. Extracted data included study duration, number of patients, and number of centers. The mortality trends and current mortality were calculated for subgroups consisting of in-hospital, ICU, 28/30-d, and 60-d mortality over 3 time periods (A, before 1995; B, 1995–2000; C, after 2000). The retrospectivity and prospectivity were also taken into account. Moreover, we present the most recent mortality rates since 2010. One hundred seventy-seven articles were included in the final analysis. General mortality rates ranged from 11 to 87% in studies including subjects with ARDS of all etiologies (mixed group). Linear regression revealed that the study design (28/30-d or 60-d) significantly influenced the mortality rate. Reported mortality rates were higher in prospective studies, such as randomized controlled trials and prospective observational studies compared with retrospective observational studies. Mortality rates exhibited a linear decrease in relation to time period ( P < .001). The number of centers showed a significant negative correlation with mortality rates. The prospective observational studies did not have consistently higher mortality rates compared with randomized controlled trials. The mortality trends over 3 time periods (before 1995, 1995–2000, and after 2000) yielded variable results in general ARDS populations. However, a mortality decrease was present mostly in prospective studies. Since 2010, the overall rates of in-hospital, ICU, and 28/30-d and 60-d mortality were 45, 38, 30, and 32%, respectively.

The present study evaluated whether drug-induced sleep endoscopy (DISE) helps identify the site of obstruction in patients with obstructive sleep apnoea (OSA). A total of 51 consecutive patients with polysomnography-confirmed OSA were enrolled in this prospective study. The presumed site of obstruction was determined according to history, otorhinolaryngologic examination, and polysomnography and a therapeutic plan designed before DISE. In 11 patients with severe OSA and/or previously failed continuous positive airway pressure (CPAP) treatment, DISE with simultaneous CPAP was performed. Multilevel collapse was noted in 49 patients (96.1%). The most frequent multilevel collapse was palatal, oropharyngeal, and tongue base collapse (n=17, 33.3%), followed by palatal and oropharyngeal collapse (n=12, 23.5%). Pathology of the larynx (epiglottis) was observed in 16 patients (31.4%). The laryngeal obstruction as a reason for intolerance of CPAP was observed in 3/11 (27.3%) patients. After DISE, the surgical plan was changed in 31 patients (60.8%). The results indicate that DISE helps identify the site of obstruction in the upper airways in patients with OSA more accurately and that the larynx plays an important role in OSA.

Emergence delirium (ED) is a postoperative complication in pediatric anesthesia characterized by a perception and psychomotor disorder, with a negative impact on postoperative recovery. As the use of inhalation anesthesia is associated with a higher incidence of ED, we investigated whether titrating the depth of general anesthesia with BIS monitor can reduce the incidence of ED. Randomized, prospective, and double-blind. Patients undergoing endoscopic adenoidectomy under general anesthesia according to a uniform protocol. A total of 163 patients of both sexes aged 3-8 years were enrolled over 18 months. Immediately after the induction of general anesthesia, a bispectral index (BIS) electrode was placed on the patient's forehead. In the study group, the depth of general anesthesia was monitored with the aim of achieving BIS values of 40-60. In the control group, the dose of sevoflurane was determined by the anaesthesiologist based on MAC (minimum alveolar concentration) and the end-tidal concentration. The primary objective was to compare the occurrence of ED during the PACU (post-anesthesia care unit) stay in both arms of the study. The secondary objective was to determine the PAED score at 10 and 30 min in the PACU and the need for rescue treatment of ED. 86 children were randomized in the intervention group and 77 children in the control group. During the entire PACU stay, 23.3% (38/163) of patients developed ED with PAED score >10: 35.1% (27/77) in the control group and 12.8% (11/86) in the intervention group (p = 0.001). Lower PAED scores were also found in the intervention group at 10 (p < 0.001) and 30 (p < 0.001) minutes compared to the control group. The need for rescue treatment did not differ between groups (p = 0.067). Individualization of the depth of general anesthesia with BIS monitoring is an effective method of preventing ED in children. NCT04466579.

Although extracorporeal life support is an expensive method with serious risks of complications, it is nowadays a well-established and generally accepted method of organ support. In patients with severe respiratory failure, when conventional mechanical ventilation cannot ensure adequate blood gas exchange, veno-venous extracorporeal membrane oxygenation (ECMO) is the method of choice. An improvement in oxygenation or normalization of acid–base balance by itself does not necessarily mean an improvement in the outcome but allows us to prevent potential negative effects of mechanical ventilation, which can be considered a crucial part of complex care leading potentially to an improvement in the outcome. The disconnection from ECMO or discharge from the intensive care unit should not be viewed as the main goal, and the long-term outcome of the ECMO-surviving patients should also be considered. Approximately three-quarters of patients survive the veno-venous ECMO, but various (both physical and psychological) health problems may persist. Despite these, a large proportion of these patients are eventually able to return to everyday life with relatively little limitation of respiratory function. In this review, we summarize the available knowledge on long-term mortality and quality of life of ECMO patients with respiratory failure.
