Our aim was to investigate whether implementation of a conservative oxygenation guideline structurally changed self-reported attitudes and actual clinical practice. METHODS After the implementation of a conservative oxygen therapy guideline in 3 teaching hospitals in the Netherlands, ICU clinicians were surveyed regarding their attitudes toward oxygen therapy. The survey results were compared with survey results taken before the introduction of the new guideline. Arterial blood gas analysis data and ventilator settings were retrieved from all patients admitted to the participating ICUs in the studied period, and changes after implementing the guideline were assessed. RESULTS In total, 180 ICU clinicians returned the survey. Compared to before implementation of a conservative oxygen guideline, more clinicians chose a preferred P aO2 and an oxygen saturation measured from an arterial sample (S aO2 ) limit after implementation of the guideline. In general, clinicians reported a more conservative approach toward management of F IO2 and less frequently increased the F IO2 . In the period after the active implementation of the guideline, 5,840 subjects were admitted to the participating ICUs and 101,869 arterial blood gas analyses were retrieved. Actual practice changed with overall lower oxygenation levels (median P aO2 77.93 mm Hg, compared to 86.93 mm Hg before implementation) of arterial blood and a decrease of PEEP and F IO2 . CONCLUSIONS Implementing a conservative oxygenation guideline was an effective method that changed self-reported attitudes and actual clinical practice and improved adherence to conservative oxygenation targets in a short period of time.

The purpose of this study was to determine the factors associated with HFNC failure by examining the current clinical practice of HFNC. METHODS From July 1, 2017, to June 30, 2018, in 5 university-affiliated hospitals in the Republic of Korea, a total of 1,161 admitted adult subjects who had HFNC administered were retrospectively enrolled and their medical records were reviewed. RESULTS Pulmonary diseases including pneumonia (n = 757, 65.2%) were the most common reason for use of HFNC. Subjects with do-not-resuscitate (DNR) or do-not-intubate (DNI) orders comprised 33.8% of the study population (n = 392); 563 subjects (48.5%) were escalated directly to HFNC from low-flow devices without applying reservoir or other high-flow devices. In the non-DNR/DNI subjects, arterial blood gas was not monitored in 15.2% and 14.8% of sfrequency, S aO2 , and S pO2 ≤ 6 h before HFNC application, and with the ROX index ≤ 6 h after HFNC application.

However, no clinical study comparing a vibrating mesh nebulizer with a jet nebulizer is available in this patient population. The purpose of this study was to compare the clinical efficacy of a vibrating mesh nebulizer to a jet nebulizer combined with a mouthpiece or mask in children with asthma exacerbations admitted to the emergency department. METHODS We conducted a single-blinded randomized clinical trial of 217 children (2-18 y old) with a moderate to severe asthma exacerbation in the emergency department. Assessment of severity was defined by our acute asthma score, adapted from the Pediatric Asthma Score. Subjects were randomized to receive bronchodilator treatment via vibrating mesh nebulizer (n = 108) or jet nebulizer (n = 109) and were treated until they achieved a mild asthma score and were discharged or until a decision to admit was made. read more All subjects were treated per .032). CONCLUSIONS Subjects treated with a vibrating mesh nebulizer required significantly fewer treatments and less time to achieve a mild asthma score. In subjects with a mask interface, the vibrating mesh nebulizer significantly reduced the probability of admission compared to jet nebulizer.

The use of an oxygen-weaning protocol may reduce this risk by pacing the titration of oxygen therapy to patient needs. ICU protocols are correlated with decreased mortality and length of stay and have great potential for cost savings. The goals of this study were to determine whether the oxygen-weaning protocol at a university-affiliated hospital was followed and to measure the length of time respiratory therapists took to wean patients once the oxygen-weaning parameters were met. METHODS This was a retrospective chart review of subjects > 18 y of age admitted to the medical ICU who underwent intubation and mechanical ventilation and were placed on an oxygen therapy protocol. The following data were collected demographics, arterial blood gases, the length of time to change F IO2 after meeting weaning parameters, and the percent change in F IO2 . RESULTS Data were collected from 30 subjects. The most common oxygen saturation parameter measured via pulse oximetry (S pO2 ) used to initiate weaning oxygen was 92%. The mean ± SD F IO2 administered to subjects was 39.6 ± 15.3% prior to extubation. The majority of subjects exhibited adequate oxygenation prior to extubation (mean ± SD) P aO2 99.3 ± 6.7 mm Hg, S aO2 95.1 ± 26.9%. The mean ± SD length of time to the first change in F IO2 from the time a subject met the weaning criteria was 9.1 ± 10.6 h (range 1-39 h; interquartile range 2-13 h). CONCLUSIONS Subjects admitted to the medical ICU who were intubated, mechanically ventilated, and placed on the oxygen therapy protocol experienced a significant delay in oxygen weaning. Closer monitoring and adherence to the oxygen-weaning protocol should be considered to reduce the potential risk for hyperoxia. Copyright © 2020 by Daedalus Enterprises.
