NCT ID: NCT06260202 Not yet recruiting - Clinical trials for Respiratory Insufficiency

Nutrition Under Noninvasive Ventilation

NUTRINIV
Start date: March 1, 2024
Phase:
Study type: Observational

Even though nutrition is a fundamental component of Intensive care unit (ICU) therapy, critically ill patients are frequently malnourished, a factor well known for its strong association with a higher risk of complications, prolonged ICU/hospital length of stay, and greater ICU readmission and mortality rates. Noninvasive ventilation (NIV) use has increased considerably over the past twenty years, making this supportive technique a keystone of acute respiratory failure (ARF) treatment. In this setting, respiratory support is provided through an interface, usually a mask or a helmet, that frequently represents an important obstacle to nutrition delivery, making oral intake impossible and posing the necessity to start enteral (EN) or parenteral nutrition (PN). Moreover, while critical care guidelines regarding nutritional management of patients receiving mechanical ventilation (MV) are well established, data and recommendations about the appropriate nutritional support to patients in NIV are still very limited. Due to this limited data, we want to describe characteristics and nutritional management of patients undergoing NIV in ICU, and to evaluate the difference between the mean caloric and protein intake of these patients and the recommended caloric and protein target for critically ill patients. Secondarily, we want to evaluate the difference of the caloric and protein intake among groups of patients undergoing different nutritional modality and to assess potential associations of the nutritional characteristics with patient outcomes.

NCT ID: NCT05964244 Not yet recruiting - Clinical trials for Noninvasive Ventilation

Impact of Noninvasive With Expiratory Washout on Respiratory Rate of Patients With Acute Hypercapnic Respiratory Failure

Start date: November 2023
Phase: N/A
Study type: Interventional

This study will determine if NIV using the Vela investigational mask with expiratory washout of the upper airway more effectively reduces respiratory rate in acute patients with hypercapnic respiratory failure. Patients admitted to hospital with acute respiratory failure (ARF) will be assessed for hypercapnic ARF by normal hospital protocols. Patients requiring noninvasive ventilation (NIV) will be set up on NIV as prescribed per standard of care. Enrollment onto the investigation will occur after the patient has been allowed to stabilize on NIV . Patients that meet the inclusion/exclusion criteria will be approached for consent. Investigation participants will receive two masks in random order; 1. NIV for one hour with the investigational mask (Vela) 2. NIV for one hour with the standard mask (Nivairo). Participants will have their physiological respiratory parameters recorded.

NCT ID: NCT04507802 Not yet recruiting - Clinical trials for Acute Respiratory Distress Syndrome

Helmet vs Face Mask in Patients With Acute Respiratory Distress Syndrome

Start date: August 2020
Phase: N/A
Study type: Interventional

The objective of this study is to evaluate the efficacy of noninvasive ventilation with helmet in reducing endotracheal intubation rates in comparison with Noninvasive Ventilation (NIV) facemask among patients with Acute Respiratory Distress Syndrome (ARDS)

NCT ID: NCT03687424 Not yet recruiting - Obesity Clinical Trials

Can High-flow Nasal Oxygenation Improve Oxygen Saturation During Analgo-sedation in Obese Adults?

Start date: October 30, 2018
Phase: N/A
Study type: Interventional

Obesity is omnipresent problem in everyday anesthesiology practice associated with low level of blood oxygen (hypoxemia) during analgo-sedation. Overweight outpatients are often scheduled for colonoscopy usually undergo analgo-sedation. In obese patients, intravenous analgo-sedation often diminish respiratory drive causing hypoxemia. To avoid hypoxemia, low-flow nasal oxygenation (LFNO) of 2-6 L/min is applied via standard nasal catheter to provide maximum 40 % of inspired fraction of oxygen (FiO2). LFNO comprises applying cold and dry oxygen which causes discomfort to nasal mucosa of patient. LFNO is often insufficient to provide satisfying oxygenation. Insufficient oxygenation adds to circulatory instability - heart rate (HR) and blood pressure (BP) disorder. On the other side, high-flow nasal oxygenation (HFNO) brings 20 to 70 L/min of heated and humidified of O2/air mixture up to 100% FiO2 via specially designed nasal cannula. Heated and humidified O2/air mixture is much more agreeable to patient. HFNO brings noninvasive support to patients' spontaneous breathing by producing continuous positive pressure of 3-7 cmH2O in upper airways consequently enhancing oxygenation. Investigators intend to analyze effect of HFNO vs. LFNO on oxygen saturation during procedural analgo-sedation for colonoscopy in obese adult patients. Investigators expect that obese patients with preserved spontaneous breathing, oxygenized by HFNO vs. LFNO, will be less prone to hypoxemia thus more respiratory and circulatory stable during procedural analgo-sedation for colonoscopy. Obese patients with applied HFNO should longer preserve: normal oxygen saturation, normal level of CO2 and O2, reflecting better respiratory stability. Investigators expect obese participnts to have more stable HR and BP, reflecting improved circulatory stability. There will be less interruption of breathing pattern of obese patients and less necessity for attending anesthesiologist to intervene.

The Effect of High-flow Nasal Oxygenation to the Saturation During Analgo-sedation in Different ASA Risk Class Patients

Start date: October 30, 2018
Phase: N/A
Study type: Interventional

Analgo-sedation is standard procedure in anesthesiology practice and is often given for colonoscopy in the setting of daily hospital. Ideally, patients should be sedated with preserved spontaneous breathing and adequate blood O2 saturation. To maintain adequate oxygenation, low-flow O2 (2-6 L/min) is usually delivered through standard nasal catheter which can provide inspired fraction (FiO2) of 40% (low-flow nasal oxygenation - LFNO). Coldness and dryness of LFNO applied may be uncomfortable to patient. Standardly applied intravenous anesthetics can lead to transient ceasing of breathing and O2 desaturation despite LFNO. Respiratory instability can also potentiate circulatory instability - undesirable changes in heart rate (HR) and blood pressure (BP). Unlike LFNO, high-flow heated and humidified nasal oxygenation (HFNO) is characterized by the oxygen-air mixture flow of 20 to 70 L/min up to 100% FiO2. Warm and humidified O2, delivered via soft, specially designed nasal cannula, is pleasant to patient. HFNO develops continuous positive pressure of 3 to 7 cmH2O in upper airway which enables noninvasive support to patient's spontaneous breathing thus prolonging time of adequate O2 saturation. Aim of this study is to compare effect of HFNO and LFNO on oxygenation maintenance before, during and after standardized procedure of intravenous analgo-sedation in normal weight patients of ASA risk I, II and III. Investigators hypothesize that application of HFNO compared to LFNO, in patients with preserved spontaneous breathing during procedural analgo-sedation, will contribute to maintaining of adequate oxygenation, consequentially adding to greater circulatory and respiratory patients' stability. Investigators expect that patients who receive HFNO will better maintain adequate oxygenation regarding improved spontaneous breathing. Also patients will have shorter intervals of blood oxygen desaturation, less pronounced rise in blood CO2 level and lesser fall of blood O2 level, less change in HR and BP. Investigators will have to exactly estimate partial and global respiratory insufficiency (blood CO2 and O2 levels) associated with LFNO and HFNO, which will be done by blood-gas analysis of 3 arterial blood samples collected before, during and after analgo - sedation via previously, in local anesthesia, placed arterial cannula. Possible complications will be explained in written uniformed consent and by anesthesiologist.
