Expiratory Central Airway Collapse and Pneumatic Stenting With Continuous Positive Pressure Titration: A Technique Description.

Objective: To provide a standardized step-by-step guide for continuous positive airway pressure (CPAP) titration during dynamic flexible bronchoscopy (DB).

Patients And Methods: This descriptive study included patients referred to Mayo Clinic for concern regarding expiratory central airway collapse (ECAC) who underwent DB with CPAP titration from April 5, 2023, to February 9, 2024. Demographic characteristics, comorbidities, pulmonary function test results, and procedural details such as anesthesia protocols, CPAP settings, outcomes of pneumatic stenting, complications, and severity of ECAC were recorded.

Impact of low dose inhaled nitric oxide treatment in spontaneously breathing and intubated COVID-19 patients: a retrospective propensity-matched study.

Background: The benefit of Inhaled nitric oxide (iNO) therapy in the setting of COVID-19-related ARDS is obscure. We performed a multicenter retrospective study to evaluate the impact of iNO on patients with COVID-19 who require respiratory support.

Methods: This retrospective multicenter study included COVID-19 patients enrolled in the SCCM VIRUS COVID-19 registry who were admitted to different Mayo Clinic sites between March 2020 and June 2022 and required high-flow nasal cannula (HFNC), non-invasive ventilation (NIV), or invasive mechanical ventilation (IMV).

Association of estimated plasma volume with new onset acute kidney injury in hospitalized COVID-19 patients.

Purpose: To explore the association of estimated plasma volume (ePV) and plasma volume status (PVS) as surrogates of volume status with new-onset AKI and in-hospital mortality among hospitalized COVID-19 patients.

Materials And Methods: We performed a retrospective multi-center study on COVID-19-related ARDS patients who were admitted to the Mayo Clinic Enterprise health system. Plasma volume was calculated using the formulae for ePV and PVS, and longitudinal analysis was performed to find the association of ePV and PVS with new-onset AKI during hospitalization as the primary outcome and in-hospital mortality as a secondary outcome.

Association of antibiotics with the outcomes in COVID-19 pneumonia patients with elevated PCT levels.

Objective: To assess antibiotics impact on outcomes in COVID-19 pneumonia patients with varying procalcitonin (PCT) levels.

Methods: This retrospective cohort study included 3665 COVID-19 pneumonia patients hospitalized at five Mayo Clinic sites (March 2020 to June 2022). PCT levels were measured at admission.

Association of plasma volume status with outcomes in hospitalized Covid-19 ARDS patients: A retrospective multicenter observational study.

Purpose: To evaluate the association of estimated plasma volume (ePV) and plasma volume status (PVS) on admission with the outcomes in COVID-19-related acute respiratory distress syndrome (ARDS) patients.

Materials And Methods: We performed a retrospective multi-center study on COVID-19-related ARDS patients who were admitted to the Mayo Clinic Enterprise health system. Plasma volume was calculated using the formulae for ePV and PVS, and these variables were analyzed for correlation with patient outcomes.

Translating Policy to Practice: An Association Between Medicare Access and Children's Health Insurance Program Reauthorization Act Implementation and Palliative Care Consultations and Perioperative Mortality in Critical Care.

Objectives: To evaluate the 30-day postoperative mortality and palliative care consultations in patients that underwent surgical procedures in the United States before and after Medicare Access and Children's Health Insurance Program Reauthorization Act (MACRA) implementation.

Design: Retrospective, Observational cohort study.

Setting: Secondary data were collected from the U.

Barriers to High Quality End of Life Care in the Surgical Intensive Care Unit.

End of life discussions frequently take place in surgical intensive care units, as a significant number of patients die while admitted to the hospital, and surgery is common during the last month of life. Multiple barriers exist to the initiation of these conversations, including: miscommunication between clinicians and surrogates, a paternalistic approach to surgical patients, and perhaps, conflicts of interest as an unwanted consequence of surgical quality reporting. Goal discordant care refers to the care that is provided to a patient that is incapacitated and that is not concordant to his/her wishes.

Expiratory Central Airway Collapse in Adults: Corrective Treatment (Part 2).

Corrective treatment of expiratory central airway collapse (ECAC) consists of placement of airway stents or tracheobronchoplasty (TBP). The indication for corrective treatment is severe central airway collapse (>90 %), and severe symptoms that cause decline in quality of life. Patients are selected to undergo a trial of tracheal "Y" stent placement.

Expiratory Central Airway Collapse in Adults: Anesthetic Implications (Part 1).

Expiratory central airway collapse (ECAC) is a general term that incorporates tracheobronchomalacia (TBM) and excessive dynamic airway collapse (EDAC). TBM and EDAC are progressive, degenerative disorders of the tracheobronchial tree, causing airway collapse. Induction of general anesthesia can trigger intraoperative airway collapse in patients with these conditions.

The Clinical Significance of Patient Specimen Transport Modality: Pneumatic Tube System Impact on Blood Gas Analytes.

Introduction: A pneumatic tube system (PTS) is a cost-effective, rapid transport modality that utilizes induced pressure changes. We evaluated the clinical importance of 2 transport modalities, human courier and PTS, for blood gas specimens.

Methods: Following open heart surgery, 35 simultaneous pairs of arterial and venous blood gas specimens were analyzed from 20 subjects.
