Targeted OXYgen Therapy in Critical Illness
Critical IllnessRespiratory FailureThe investigators propose to conduct a feasibility, multi-centre, randomised controlled trial of targeted oxygen therapy in adult critically ill patients receiving mechanical ventilation via an endotracheal tube as part of their treatment for respiratory failure. Participants will be allocated to either a normal blood oxygen target group or a lower than normal blood oxygen target group. The primary purpose of the study will be to assess the feasibility of recruiting complex patients who lack capacity into a clinical trial in which oxygenation is being assessed, and that the clinicians responsible for these patients are able to deliver the intervention effectively. The safety of using a lower than normal blood oxygen target will also be assessed and blood samples taken for subsequent investigation of the biological mechanisms underlying the observed changes. Participants will be randomised (1:1) into either an intervention or control group. The intervention in this trial is tightly controlled administration of oxygen to patients to achieve a haemoglobin oxygen saturation (SpO2) of 88-92%. The control group will also have tightly controlled oxygen administration, but to achieve an SpO2 of 96% or above. The target for the control group represents a normal SpO2, whilst that in the intervention group is lower than what is considered to be normal. It should be noted that although lower than normal, this SpO2 is close to what the general public experience when travelling by pressurised aircraft as the fractional inspired oxygen concentration in that situation is only 0.15-0.17 (15-17%). The controlled oxygen administration would commence as soon as possible after admission to the critical care unit and end following removal of the participant's artificial breathing tube. The researchers and clinical team cannot be blinded to treatment allocation, due to the nature of the intervention. Those analysing the data will be blinded to the intervention.
Cognitive and Behavioral Intervention for the Management of Episodic Breathlessness in Patients...
DyspneaRespiratory Insufficiency10 moreEpisodic breathlessness is a common and distressing symptom in patients with advanced disease such as cancer, chronic obstructive pulmonary disease (COPD) and chronic heart failure. Since the short duration of the majority of breathless episodes limits the effectiveness of pharmacological interventions (e.g. opioids), non-pharmacological management strategies play a major role. As non-pharmacological strategies patients use, for example, cognitive and behavioural methods such as breathing or relaxation techniques. The aim of the study is to test a brief cognitive and behavioural intervention for an improved management of episodic breathlessness. Initially, a Delphi procedure with international experts has been used to develop the brief intervention consisting of various non-pharmacological strategies to enhance the management of breathless episodes. In the single-arm therapeutic exploratory trial (phase II), the feasibility and potential effects of the brief intervention, such as patient-reported breathlessness mastery, episodic breathlessness characteristics, quality of life, symptom burden, caregivers' burden, and breathlessness in general will be examined. The results of the study form the basis for planning and implementing a subsequent confirmatory randomized control trial (phase III).
Exercise Capacity Under Various FiO2 and Oxygen Flow Rates Using HFNC
High-flow Nasal CannulaExercise Capacity1 moreThe purpose of this study is to compare the exercise capacity (6-min walking distance) under the following 4 conditions using High-flow nasal cannula (HFNC); 1. FIO2 value that the minimum SpO2 value in a 6-minute walking test (6MWT) is 86-88%, and a flow of 10 L/min 2. FIO2 value that the minimum SpO2 value in a 6MWT is 86-88%, and a flow of 40-50 L/min 3. FIO2 value that the minimum SpO2 value in a 6MWT is 92-94%, and a flow of 10 L/min 4. FIO2 value that the minimum SpO2 value in a 6MWT is 92-94%, and a flow of 40-50 L/min
Vital Sign Monitoring With Continuous Pulse Oximetry and Wireless Clinician Notification After Surgery...
Respiratory DepressionPatients are at risk of respiratory depression after having surgery. The medications that patients are treated with to control their pain can impair their breathing and this can progress to respiratory and cardiac arrest and even death. Vital signs assessment on surgical wards is usually done every 4 hours and this may be insufficient to identify and manage many cases of respiratory depression. The aim of this study is to determine the impact on safety and nursing workflow of a respiratory monitoring on two surgical wards by measuring safety outcomes. Respiratory depression is a serious complication of pain treatment that can lead to patient complications and death. The level of monitoring available in hospitals by nursing staff is insufficient to manage this problem. If this new monitoring technology works as designed then patient safety can be improved while maintaining effective pain therapy.
Enteral Feeding Composition and Acute Respiratory Failure
Acute Respiratory FailureThis study aimed to investigate the effect of enteral feeding's macronutrient composition on inflammatory mediators, oxidative stress and outcomes in Intensive Care Unit (ICU) patients with acute respiratory failure. In this double-blind randomized control trial, 42 patients of both sexes and diagnosed with acute respiratory failure in ICU that receive enteral feeding, will be randomly assigned to three groups of 14 each. First Intervention group; high-protein low-carbohydrate diet with high olive oil, the second intervention group; high-protein low-carbohydrate diet with high sunflower oil and control; high-protein kitchen formula. Intravenous levels of uric acid, high sensitive C-Reactive Protein (hs-CRP), Interleukin 6 (IL-6) and Total Antioxidant Capacity (TAC) measured at days 0 and 10. As well as, organ failure, duration of ventilation, length of ICU stay and mortality rates will be evaluated.
Tracheobronchial Secretion Removal
RespirationArtificial1 morePatients undergoing intubation and mechanical ventilation require removal of secretion by means of trachoebronchial suctioning. Timing of the procedure is mainly based on clinical parameters. TBA Care® is a new commercially available device designed to generate a signal when secretions are present in the respiratory tract of intubated patients, thus indicating the need for endotracheal suctioning only when necessary and prior to clinical deterioration. In a prospective randomized trial in intubated and mechanically ventilated patients of a general ICU the researchers investigated the efficacy of TBA Care® in detecting the presence of retained secretions compared to the standard indicators.
Sleep and Circadian Rhythms in Mechanically Ventilated Patients
Respiratory FailureCritical IllnessThis study examines the feasibility of assessing sleep and circadian rhythmicity in critically ill patients undergoing mechanical ventilation. Secondarily, it will examine the feasibility of reducing subject exposure to environmental light and noise and of delivering routine care according to classical day/night routines.
Patients-ventilator Interaction During Sleep: Effect of Humidification System
Chronic Hypercapnic Respiratory FailureAt present, little data is available in the medical literature regarding the affects of humidification on NIMV efficacy, sleep quality and upper airway symptoms in patients undergoing nocturnal NIMV. The aim of the present pilot study is to assess the impact of two humidification systems on sleep quality, NIMV efficacy, patient-ventilator interaction, prevalence of NIMV side effects, compliance to treatment, in a group of stable patients already enrolled in a long-term nocturnal mechanical ventilation program for chronic hypercapnic respiratory failure or sleep hypoventilation.
Telemedicine for Patients With Chronic Respiratory Insufficiency
Chronic Respiratory FailureIn unstable patients needing oxygen and/or home mechanical ventilation, a nurse-centred TM programme (supported by continuous availability of a call centre and a pulsed oxygen system) is cost/effective saving health care resources.
Frequency of Oral Care Intervention Study
Respiratory FailureTooth brushing for patients with breathing tubes is routinely provided by the bedside nurse as part of clinical care. The purpose of this study is to determine how often tooth brushing should occur for adult patients with breathing tubes (mechanical ventilation), balanced with equivalence and safety.
