Filter by:Clinical trial evaluating the efficacy and safety of salbutamol for the treatment of neonates with a gestational age between 32 and 42 weeks with transient tachypnoea of the newborn (TTN).
The Hospital Airway Resuscitation Trial (HART) is a cluster-randomized, pragmatic trial of advanced airway management with a strategy of first choice supraglottic airway vs. first choice endotracheal intubation during in-hospital cardiac arrest.
Diseases of the lungs can be life-threatening. When these organs fail to adequately work, treatments to support their function are offered, often in Intensive Care Units (ICU). Respiratory failure patients may need sedation and placement of a tube in their windpipe so that a mechanical ventilator can take over their breathing until they have recovered enough to breathe again on their own. One problem that occurs in patients under mechanical ventilation is that parts of the lung tissue tend to collapse (atelectasis), reducing the amount of the lung that is able to transfer oxygen and carbon dioxide effectively and even progressing to pneumonia. To address this problem, ICU doctors often perform a procedure named 'recruitment manoeuvre', which involves briefly inflating the patient's lungs with enough pressure to try to open up the collapsed areas of lung. However, fundamental aspects of the change in the functioning of the heart and lungs that occur during and after such manoeuvre are not fully understood. In this study, funded by the University of Oxford, the investigators wish to study patients with respiratory failure who are receiving mechanical ventilation. Participants will be recruited at the ICU of the Royal Berkshire Hospital having their cardiopulmonary data collected over the course of a day. During this period, some patients will be assessed to determine whether they may benefit from a recruitment manoeuvre using a pressure-volume curve. As this assessment is not perfect, the investigators wish to study which features of this curve predict a successful recruitment. The investigators will do this by evaluating the volume of the lung before and after the recruitment manoeuvre is performed using a device named Optical Gas Analyser. A better understanding of the effects of the recruitment manoeuvre will help the investigators to determine how and when such manoeuvres should be performed in critically ill patients.
In patients undergoing spontaneous breathing (SB) deep sedation there is a re-distribution of ventilation towards lungs non-dependant areas (ventral areas in supine position). Non-invasive ventilation (NIV), offering positive pressure, should favour a better ventilation of dependant areas (dorsal areas in supine position), making ventilation more homogeneous and increasing functional residual capacity. Electrical impedance tomography (EIT) is a non-invasive, non-operator dependent, bedside, radiations-free diagnostic tool, feasible in paediatric patients and repeatable; it allows to study ventilation distribution, and it can measure and calculate also parameters that are related to the homogeneity of ventilation and the response to certain therapeutic maneuvers, such as anaesthesia or PEEP-application. Uses of EIT in paediatric age are described in literature, but it has never been described as being used in Non-Operating Room Anaesthesia, nor in other cases of SB deep sedation. In addition, the impact of NIV on the distribution of ventilation in healthy paediatric patients undergoing deep sedation has never been described.
Evaluation of the safety and efficacy of using the Lumena mask, compared to commercially-available, commonly used Oro-nasal masks.
The COSMIC trial will be a multicentred, national, parallel-group, pragmatic vanguard pilot trial.
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).
A retrospective study to evaluate the predictability of abnormal arterial blood gas measurements through novel observations of continuous trends in electronically measured respiratory in a mixed cohort of respiratory compromised patients.
The TONES trial aims to evaluate the neuroventilatory efficiency (NVE = tidal volume / peak voltage of diaphragm contraction) measured during a zero-assist manoeuvre (ZAM, i.e. with PEEP but without pressure support). This novel parameter, NVE-ZAM, will be studied in a blocked, crossover, repeated measures design. Possible confounders, such as activity of respiratory muscles other than the diaphragm, are included. The investigators hypothesized that - the NVE during a zero-assist maneuver has a low variability and high repeatability at the same level of PEEP (within subjects, within blocks) - NVE-ZAM trends differ between participants (between subjects, within blocks) and between PEEP levels (within subjects, between blocks) The primary aim is to study the variability and repeatability of the NVE-ZAM within subjects and within blocks. Additionally, the effect of PEEP, muscle fatigue and recruitment of the accessory and expiratory muscles of respiration on the NVE-ZAM will be studied in an exploratory analysis (in multiple combinations of within and between subjects and/or blocks).
The purpose of this study is to investigate whether protocolized vasopressor use for patients with normal blood pressure undergoing rapid sequence intubation improves hemodynamic parameters and mitigates adverse events. The hypothesis is that use of vasopressors during Rapid Sequence Intubation will prevent substantial decreases in blood pressure when compared to normal intravenous fluids.
