Filter by:The study aims to predict the failure of High-flow Nasal Cannula oxygenation therapy by ultrasound evaluation of diaphragm and intercostal muscle contraction during the first 24 hours.
This study aims to compare the effectiveness of conventional oxygen therapy oxygen and high-flow nasal cannula therapy on oxygen saturation (SpO2), measuring number of SpO2 drop >4% of base line oxygen saturation (o2 desaturation index), length of the ICU stay, and the need of use supplemental continuous positive airway pressure (CPAP) support in any of the study groups in the postoperative ICU setting.
The goal of this observational study is to identify the variables that predict treatment failure in order to identify the patients in which HFNC treatment may fail and not delay the transition to advanced respiratory support treatments in these patients. The main questions it aims to answer are: - What factors contribute to the failure of HFNC treatment in these children? - What is the frequency of HFNC treatment failure in children with moderate and severe respiratory distress? Researchers will compare the group whose HFNC treatment was successful with the group whose HFNC treatment failed to identify factors that cause treatment failure.
Patients at high risk of post-operative pulmonary complications (PPC) will be screened out from gynecological tumor patients undergoing surgical treatment, and randomly assigned into the HFNC group and control group, which uses conventional nasal cannula oxygen therapy. The primary outcome is the incidence of PPC, including postoperative hypoxemia, atelectasis, pneumonia, etc. Secondary outcomes are the improvement of postoperative oxygenation, antibiotic use, length of hospital stay, adverse events related to oxygen therapy, etc.
High flow nasal cannula (HFNC) is used in interventional procedures to prevent hypoxia during sedation. In patients with a patent airway, HFNC reduces dead space ventilation as well. It is unknown if dead space ventilation is also reduced by HFNC in an EndoBroncheal UltraSound procedure, in which the airway is partially blocked by the endoscope. Especially in patients with Chronic Obstructive Pulmonary Disease (COPD) the partial blocking of the airway may reduce ventilation. If HFNC is able to reduce dead space during an EBUS-procedure, it may facilitate CO2 clearance, which may lead to a reduction in work of breathing. This study aims to investigate if HFNC reduces dead space ventilation in patients undergoing an EBUS-procedure and if this is flow-dependent. A randomized, double-blinded, cross-over study is designed.
High flow nasal cannula administration in critically ill patients is frequently used to improve acute respiratory failure or to prevent respiratory failure after extubation. It acts generating a mild positive pressure in the airways and by reducing respiratory effort of patients. However to the best of our knowledge, no study to date has directly measured the amount of positive pressure generated in the trachea of patients. The primary aim, therefore, of this study measures this positive pressure after extubation in critically ill patients.
In patients with acute hypoxemic respiratory failure (AHRF), High Flow Nasal Therapy (HFNT) improves oxygenation, tolerance, and decreases work of breathing as compared to standard oxygen therapy by facemask. The hypothesis is that this flow challenge (ROX index variation from 30 to 60L/min) could be used as a test for assessing changes in lung aeration, analyzed by the variation in end expiratory lung volume (ΔEELV), in patients treated with HFNC. It may allow to personalize the flow settings during HFNC. In this sense, an increase in EELV will be observed with higher flows in responders and, therefore, these participants may benefit from increasing the flow. In contrast, to increase the flow in non-responders (no significant increase in EELV with higher flows) increase the risk of patient self-inflicted lung injury (P-SILI).
In patients with acute hypoxemic respiratory failure (AHRF), High Flow Nasal Therapy (HFNT) improves oxygenation, tolerance, and decrease work of breathing as compared to standard oxygen therapy by facemask. Current guidelines recommend adjusting oxygen flow rates to keep the oxygen saturation measured by pulse oximetry (SpO2) in the target range and avoid hypoxemia and hyperoxemia. The hypothesis of the study is that closed loop oxygen control increases the time spent within clinically targeted SpO2 ranges and decreases the time spent outside clinical target SpO2 ranges as compared to manual oxygen control in ICU patients treated with HFNT.
Obstructive sleep apnea (OSA) is a common sleep disturbance that can cause intermittent hypoxia, hypercapnia, and sleep structure disorders. The presence of OSA is associated with worse outcomes after surgery including increased incidence of complications. High-flow nasal cannula (HFNC) therapy can improve oxygenation of OSA patients by maintaining a certain positive pressure in the nasopharyngeal cavity. Previous studies showed that, dexmedetomidine supplemented analgesia can improve sleep quality and pain relief. The investigators hypothesize that, for high-risk OSA patients following major non-cardiac surgery with HFNC therapy, dexmedetomidine supplemented analgesia can improve sleep quality. The purpose of this pilot randomized controlled trial is to investigate the impact of dexmedetomidine supplemented analgesia on sleep quality in high-risk OSA patients after major non-cardiac surgery.
Sepsis is a heterogeneous syndrome that is caused by the host imbalance immune response. At 1991, the American College of Chest Physicians/Society of Critical Care Medicine Consensus Conference developed a definition of sepsis. After more than 20 years, it was gradually developed in 2016 to the third edition of the guidelines for sepsis(Sepsis-3). Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. According to the National Health Insurance claims database of Taiwan, The incidence rate was 772.1/100,000 persons in 2012. From 2002 to 2012, the incidence of sepsis increased by 18.7%. The mortality of severe sepsis was 17.9%. However, has increased to 33% when developed to septic shock. Even in foreign studies, the intensive care unit mortality rate can reach 40%. Although sepsis was defined in 1991, after these years, the treatment of sepsis is still a goal that must be worked hard. According to Sepsis-3, must first use the qSOFA (quick Sepsis Related Organ Failure Assessment) to assess whether the patient's blood pressure, respiratory rate, and state of consciousness meet more than two criteria, which is sepsis. If the SOFA score (Sequential Organ Failure Assessment) is further evaluated, with at least two of the following symptoms, including poor oxygenation in the lungs, hypotension or use of a vasopressor, thrombocytopenia, conscious change (Glasgow Coma Scale), bilirubin increase and creatinine rise or oligouria. If the patient must use a vasopressor to maintain a mean arterial pressure (MAP) of 65 mmHg and serum lactate more than 18 mg/dL, it is Septic shock. In clinical assessment, qSOFA (rapid sepsis-associated organ failure assessment) can also be used to assess blood pressure, respiratory rate, and state of consciousness to confirmed sepsis. According to the above assessment conditions, patients with sepsis are highly prone to respiratory failure during the disease process. In recent trials, about 40% to 85% of patients with sepsis must be need endotracheal intubation, showing the high intubation rate. Patients after intubation may cause lung injury due to improper ventilator settings (Ventilator-induced lung injury, VILI). And 10% to 25% will be combined with pneumonia caused by the ventilator (ventilator-associated pneumonia, VAP). Mortality can reach 20% to 33%. So if we can reduce septic patient's intubation rate then we can reduce the complication caused by the ventilator. A high flow nasal cannula (HFNC) is a relatively new device for respiratory support. Patients received high-flow conditioned oxygen therapy through a nasal prong. A number of physiological effects have been described with HFNC: pharyngeal dead space washout, a positive expiratory pressure to reduce work of breathing, improve breathing synchronization. These benefits can reduce the intubation rate. The benefit of the HFNC in septic patients is not very clear. By this prospective study to investigate the septic patients who have been admitted to the intensive care unit. The study method is to ask the patient whether they agree to participate in the trial after the patient is transferred to the intensive care unit. The patient will randomly assign the subjects to the general oxygen therapy and the HFNC group after signing the subject consent form. This study aimed to determine whether high-flow oxygen therapy immediately would reduce the need for intubation compared with standard oxygen therapy in sepsis patients.
