Active clinical trials for "Respiratory Insufficiency"

This study will evaluate the ability of High Velocity Nasal Insufflation [HVNI] next generation nasal cannula designs to effect ventilation and related physiological responses relative to the conventional legacy cannula design.

This study aims to determine if a strategy of recommending prone (on stomach) positioning of patients positive or suspected positive for coronavirus disease 2019 (COVID-19) requiring supplemental oxygen, but not mechanically ventilated, Is feasible in the inpatient setting. This study will be performed as a pragmatic pilot clinical trial to gain information relevant to the future conduct of a larger trial.

While there is only one study examining the effect of WBV on oxygen consumption and cardiovascular responses in individuals with stroke, no study has been found on the effect of WBV on respiratory capacity and flow volumes and changes in functional capacity due to effort. In this study, it was aimed to investigate whether the WBV treatment protocol determined has an effect on functional capacity and respiratory functions in individuals with stroke.

A prospective randomized controlled trial was conducted to collect patients with prolonged mechanical ventilation. Patients were randomly assigned to receive PAV+ or PSV as weaning mode. Weaning outcomes were compared between 2 groups.

Effectiveness of BIPAP is evaluated in Type-2 failure but evaluation of effectiveness of CPAP in Type-2 respiratory failure in post cardiac surgery patients was not done. So the objective of this study is to determine the acute effects of BIPAP vs. CPAP with conventional physiotherapy on Hemodynamics and Respiratory parameters in management of Type 2 Respiratory failure in post cardiac surgery patients.

The execution of diagnostic-therapeutic investigations by bronchial endoscopy can expose the patient to acute respiratory failure (ARF). In particular, the risk of hypoxemia is greater during broncho-alveolar lavage (BAL). For this reason, oxygen therapy is administered at low or high flows during the course of bronchoscopic procedures, in order to avoid hypoxemia. Few clinical studies have demonstrated the efficacy and safety of high flow oxygen through nasal cannula (HFNC) during BAL procedures, and no study has evaluated, during bronchial endoscopy, the effects of HFNC on diaphragmatic effort (assessed with ultrasound) and aeration and ventilation of the different lung regions (assessed with electrical impedance tomography). Therefore, investigators conceived the present randomized controlled study to evaluate possible differences existing during bronchoscopy between oxygen therapy administered with HFNC and conventional (low-flow) oxygen therapy, delivered through nasal cannula.

Optical guidance for percutaneous tracheostomy in intensive care is usually performed by conventional multi use bronchoscopy. Recently a single use bronchoscope has been introduced that allows for endotracheal visualization. For feasibility evaluation, 23 patients in intensive care receive percutaneous tracheostomy with optical guidance by the Ambu® aScopeTM 4 bronchoscope and 23 patients in intensive care receive percutaneous tracheostomy with a conventional bronchoscope (Olympus BF Type P60). The primary end point is the visualization through the single use bronchoscope of endotracheal landmark structures for tracheostomy and visualization of the needle insertion (according to score, see detailed description).

Nearly 25% of Americans die in intensive care units (ICUs). Most deaths in ICUs are expected and involve the removal of ventilator support, or palliative withdrawal of mechanical ventilation (WMV). Prior work by the Principal Investigator (PI) found that patient suffering can be common; with 30-59% of patients going through this process experiencing distress. Thus, experts and national organizations have called for evidence to inform guidelines for WMV. This research study will 1) develop and refine a Comfort Measures Only Time out (CMOT) intervention consisting of a structured time out with check-list protocol for the ICU team (nurse, physician, respiratory therapist) to improve the process of WMV. and 2) Pilot test the CMOT intervention in 4 ICUs (2 medical/2 surgical) among 40 WMV patients.

Clinicians perform rapid sequence induction, laryngoscopy, and tracheal intubation for more than 5 million critically ill adults as a part of clinical care each year in the United States. Failure to intubate the trachea on the first attempt occurs in more than 10% of all tracheal intubation procedures performed in the emergency department (ED) and intensive care unit (ICU). Improving clinicians rate of intubation on the first attempt could reduce the risk of serious procedural complications. In current clinical practice, two classes of laryngoscopes are commonly used to help clinicians view the larynx while intubating the trachea: a video laryngoscope (equipped with a camera and a video screen) and a direct laryngoscope (not equipped with a camera or video screen). For nearly all laryngoscopy and intubation procedures performed in current clinical practice, clinicians use either a video or a direct laryngoscope. Prior research has shown that use of a video laryngoscope improves the operator's view of the larynx compared to a direct laryngoscope. Whether use of a video laryngoscope increases the likelihood of successful intubation on the first attempt remains uncertain. A better understanding of the comparative effectiveness of these two common, standard-of-care approaches to laryngoscopy and intubation could improve the care clinicians deliver and patient outcomes.

Rationale: The most common approach to weaning infants and children is gradual reduction of ventilatory support ("traditional approach"). Alternatively, another approach to weaning is attempted with alternating periods of complete ventilatory support and graded spontaneous breathing with assistance ("sprinting approach"). Both approaches are used randomly in our unit: the decision to use which approach is dependent upon the preferences of the attending physician as described in many observational single center studies. To date, there is no data comparing the safety and efficacy of the "sprinting" approach with more traditional approaches of weaning in children. Hence, numerous issues remain unanswered, including the work-of-breathing during each approach. For this research proposal, we want to measure the work-of-breathing daily, using the traditional approach (the area under the oesophageal pressure - volume curve) and study its correlation with clinical parameters and EMG activity of the diaphragm and intercostal muscles from the moment that the patient is weaned off the ventilator. Objective: The primary objective for this study is to compare for each patient of the work-of-breathing during the "sprinting"approach and the "traditional approach.The secondary objectives for this study are to compare the oesophageal pressure rate and (PRP) and pressure time product (PTP), the PaO2/FiO2 ratio, global and regional distribution of tidal volume measured using electrical impedance tomography (EIT), phase distribution of the respiratory inductive plethysmography (RIP) signal and the EMG activity of the diaphragm and intercostal muscles between the "sprinting"and the "traditional" approach.. Study design: This is a prospective exploratory study with invasive measurements in a 20 bed tertiary paediatric intensive care facility at the Beatrix Children's Hospital/University Medical Centre Groningen. Study population: All mechanically ventilated children aged 0 to 5 years with or without lung pathology admitted to the paediatric intensive care unit are eligible for inclusion. Inclusion criteria include mechanical ventilation for at least 48 hours, weight ≥ 3 kg, sufficient respiratory drive present, deemed eligible for weaning by the attending physician, and stable haemodynamics (defined by the absence of need for increase in vaso-active drugs and/or fluid challenges at least 6 hours prior to enrolment). Exclusion criteria include mechanical ventilation less than 48 hours, not eligible for weaning (usually when there are unstable ventilator settings, defined by the need for increase of inspiratory pressures or positive end-expiratory pressure, and a FiO2 > 0.6 within 6 hours prior to enrolment), unstable haemodynamics (defined by the need for increase in vaso-ative drugs and/or fluid challenges within 6 hours prior to enrolment), leakage around the endotracheal tube > 5%, admitted to the neonatal intensive care unit, preterm birth with gestational age corrected for post-conceptional age less than 40 weeks, congenital or acquired neuromuscular disorders, congenital or acquired central nervous system disorders with depressed respiratory drive, congenital or acquired damage to the phrenic nerve, congenital or acquired paralysis of the diaphragm, use of neuromuscular blockade prior to enrolment, uncorrected congenital heart disorder, and chronic lung disease. Main study parameters/endpoints: The main study parameter is the level and time course of the patient's work-of-breathing mathematically calculated by the area under the pressure-volume curve Secondary study parameters include the level and time course of the PRP and PTP, level and time course of oxygenation (PaO2/FiO2 ratio), global and regional distribution of tidal volume, phase distribution, EMG activity of the diaphragm and intercostal muscles, heart rate, respiratory rate.. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: There are a priori no specific benefits for the patients who participate in the study.
