Acoustic monitoring of the artificial airway — experimental results

1997

Non-invasive acoustic airway-monitoring was evaluated in an experimental study. Recording amplitude and travel time of acoustic pulse response, an acoustic pattern of airway's geometry was then calculated. Measurements on models and excised human cadaver lungs were performed to discover whether displacement or obstruction of the artificial airway could be detected by its acoustic equivalent. Regression analysis revealed a close correlation between displacement of tracheostomy tubes and the shifting of the acoustic area-distance function (corr. coeff.: 0.97-1) and an adequate correlation between acoustic and planimetrical determination of cross-sectional area within the tubes (corr. coeff.: …

Long-term functional and psychological recovery in a population of acute respiratory distress syndrome patients treated with VV-ECMO and in their car…

2019

Background Acute respiratory distress syndrome (ARDS) survivors are affected with long-term physical/mental impairments, with improvements limited mostly to the first year after intensive care (ICU) discharge. Furthermore, caregivers of ICU patients exhibit psychological problems after family-member recovery. We evaluated the long-term physical and mental recovery of ARDS survivors treated with veno-venous extracorporeal membrane oxygenation (VV-ECMO), and the long-term psychological impact on their caregivers. Methods Single-center prospective evaluation of a retrospective cohort of 75 ARDS patients treated with VV-ECMO during a seven-year period (25.10.2009-11.08.2016). Primary outcomes w…

Tracheomalacia Repair Using Ceramic Rings

1992

Tracheomalacia resulting from tracheostomy or compressive thyroid disease often represents a difficult problem in airway management. In an attempt to improve this condition, biocompatible ceramic rings were surgically implanted in 16 patients to restore normal patency of the airway by first expanding the tracheal lumen lateral, and then in an anterior dimension. Preoperatively, patients displayed moderate to severe obstruction with marked restrictions in lifestyle, as confirmed by history, physical examination, and airway resistance studies. Additionally, three of these patients were trach-dependent at the time of implantation. Postoperatively all 16 patients have normal airway resistance p…

Expiratory airflow obstruction due to tracheostomy tube: A spirometric study in 50 patients

2018

OBJECTIVES Tracheostomy is commonly used in intensive care units and in head and neck departments. Airway obstruction due to occluded cuffless tracheostomy tubes themselves remains unknown, although capping trials are commonly used before decannulation. The aim of this study was to evaluate the extent to which airway obstruction can be caused by occluded cuffless tubes in patients who underwent head and neck surgery. DESIGN Prospective Research Outcome. SETTINGS University teaching hospital. PARTICIPANTS Fifty patients requiring transient tracheostomy after head and neck surgery. MAIN OUTCOME MEASURES A flow-volume loop (FVL) through the mouth using a portable spirometer, with the occluded …

Rational Management of Macroglossia Due to Acquired Systemic Amyloidosis: Does Surgery Play a Role?

Outcome and attitudes toward home tracheostomy ventilation of consecutive patients: a 10-year experience.

2008

Summary Objectives To describe survival, predictors of long-term outcome and attitudes in patients treated at home by tracheostomy-intermittent positive-pressure ventilation (TIPPV) for respiratory failure during a 10-year period (1995–2004). Methods Seventy-seven consecutive patients were treated by TIPPV at home. Patients were divided into three groups: neuromuscular, pulmonary, and non-pulmonary patients. Effects of TIPPV on survival, factors influencing outcome after TIPPV, and attitudes of patients and caregivers regarding mechanical ventilation were studied. Results Forty-one patients (53%) were neuromuscular, 19 (25%) were affected by pulmonary diseases, and 17 (22%) by non-pulmonary…

Long-Term Ventilation in Neuromuscular Patients: Review of Concerns, Beliefs, and Ethical Dilemmas

2019

<b><i>Background:</i></b> Noninvasive mechanical ventilation (NIV) is an effective treatment in patients with neuromuscular diseases (NMD) to improve symptoms, quality of life, and survival. <b><i>Summary:</i></b> NIV should be used early in the course of respiratory muscle involvement in NMD patients and its requirements may increase over time. Therefore, training on technical equipment at home and advice on problem solving are warranted. Remote monitoring of ventilator parameters using built-in ventilator software is recommended. Telemedicine may be helpful in reducing hospital admissions. Anticipatory planning and palliative care should be …

Mechanical insufflation-exsufflation vs. tracheal suctioning via tracheostomy tubes for patients with amyotrophic lateral sclerosis: a pilot study.

2003

To compare the effects of mechanical insufflation-exsufflation vs. suctioning via tracheostomy tubes on respiratory variables for six amyotrophic lateral sclerosis patients.In this prospective crossover study, six consecutive patients with amyotrophic lateral sclerosis who required continuous mechanical ventilation via tracheostomy tubes and developed chest infections underwent measurement of pulse oxyhemoglobin saturation (SpO2), peak inspiratory pressure (PIP), mean airway pressure (Pawm), and work of breathing performed by the ventilator (WOBv) at baseline and 5 and 30 min after tracheal suctioning and 5 min after mechanical insufflation-exsufflation.The baseline values were 93.50 +/- 2.…

Extubation in neurocritical care patients: the ENIO international prospective study

2022

Purpose: Neurocritical care patients receive prolonged invasive mechanical ventilation (IMV), but there is poor specific information in this high-risk population about the liberation strategies of invasive mechanical ventilation. Methods: ENIO (NCT03400904) is an international, prospective observational study, in 73 intensive care units (ICUs) in 18 countries from 2018 to 2020. Neurocritical care patients with a Glasgow Coma Score (GCS) ≤ 12, receiving IMV ≥ 24 h, undergoing extubation attempt or tracheostomy were included. The primary endpoint was extubation failure by day 5. An extubation success prediction score was created, with 2/3 of patients randomly allocated to the training cohort …

Epidemiology and patterns of tracheostomy practice in patients with acute respiratory distress syndrome in ICUs across 50 countries

2018

Background: To better understand the epidemiology and patterns of tracheostomy practice for patients with acute respiratory distress syndrome (ARDS), we investigated the current usage of tracheostomy in patients with ARDS recruited into the Large Observational Study to Understand the Global Impact of Severe Acute Respiratory Failure (LUNG-SAFE) study. Methods: This is a secondary analysis of LUNG-SAFE, an international, multicenter, prospective cohort study of patients receiving invasive or noninvasive ventilation in 50 countries spanning 5 continents. The study was carried out over 4 weeks consecutively in the winter of 2014, and 459 ICUs participated. We evaluated the clinical characteris…
