Filter by:Opioids are commonly prescribed for moderate to severe pain. While initially intended for moderate to severe acute and cancer pain, opioids are currently frequently considered and prescribed in chronic noncancer pain. Due to the large increase in opioid prescription rate, the number of unintentional drug overdoses is rapidly increasing, not only in the Unites States but also in the Netherlands. A potential lethal consequence of an opioid overdose is opioid-induced respiratory depression. Additionally, it is well known that opioids are often used (and abused) in combination with other legal or illicit substances, for example alcohol, benzodiazepines, cannabis, neuropathic pain medication including the anticonvulsant pregabaline. There are no high-quality data on the interaction between oxycodone and (neuropathic pain) medication on the ventilatory control system. Case reports and randomized studies show that pregabalin induces respiratory depression when combined with opioids. Some alternatives to pregabalin may have a better safety profile. One such alternative is lacosamide, an antiepileptic with a different mode of action than pregabalin, and effective in the treatment of neuropathic pain. The hypothesis is that in contrast to lacosamide, pregabalin will increase the respiratory depressant effect of low-dose oxycodone. The objective of the study is to quantify the effect of pregabalin and lacosamide on oxycodone-induced respiratory depression. 24 participants will be screened beforehand if subjects meet the inclusion and exclusion criteria. If so, the subjects will visit the hospital twice. On both occasions, participants will take a 10 mg oxycodone tablet and 90 minutes after a capsule of pregabalin or lacosamide. The order of visits will be randomized. During the visits, at set time points the hypercapnic ventilatory response will be measured, relief of nociception, pupil diameter and several side effects other than respiratory depression. There will be a washout period of 7 days between study visits with the study ending after 2 visits. Amendment: In order to get an impression of the effect of 10 mg oxycodone per se, one open label arm of just 10 mg oxycodone was added as a visit 3. Since the procedures in this third arm will be identical to the two blinded arms, no changes will be made to any of the procedures apart from not administering any lacosamide or pregabalin.
The optimal timing of tracheostomy insertion remains uncertain. We hypothesized that a clinical pathway including expert-informed risk assessment regarding predicted duration of mechanical (MV) would enhance the effectiveness of early percutaneous dilatational tracheostomy (PDT) for patients with anticipated prolonged durations of MV, as reflected by duration of ventilation, complications, and patient-centered outcomes.
The study was a retrospective observational cohort where patient medical record review was done and data were gathered on 419 cases. The ICU admission pattern and patient outcome were the primary outcomes presented in the manuscript.
The investigators recently evaluated 4 different oximeters among the most commonly used with arterial catheter in place and compared SpO2 with SaO2 obtained on arterial gas. Correlations between SaO2 and SpO2 were poor for all oximeters, as previously known, and SpO2-SaO2 bias were different between oximeters. Some oximeters (Masimo, Nellcor) had lower biases but they detected less well hypoxemia. Some oximeters underestimated SaO2 (Nonin) but detected very well hypoxemia, and some overestimated SaO2 (Philips). The investigators concluded that oximeters provide different informations to clinicians, and oxygenation targets should take into account for these differences. The assumption is that the SpO2 target AND oximeter used will both have an impact on oxygen flows and that these effects will add up. With a high SpO2 target, oxygen flows will be significantly greater and with the Nonin oximeter, the required flows will be greater than with the Philips oximeter. NB: the results obtained were in a population with light skin pigmentation (96% of the patients were Fitzpatrick 1-2, reflecting the local hospitalized population).
The study is aimed at the clinical and laboratory characteristics of patients with completed vaccination against SARS-CoV-2 admitted to the hospital in the standard ward and intensive care unit due to the severe course of COVID-19.
The study will be a multicenter, multinational, prospective single arm blinded non-interventional follow-up study (from DXT-CS-005) to validate RESPINOR DXT's performance to identify patients at increased risk of weaning failure during the spontaneous breathing trial (SBT). Continuous diaphragmatic excursion measurements by RESPINOR DXT will be conducted during the patients' first SBT. The recording shall be initiated 15 minutes prior to the first SBT and will end 15 minutes post SBT. All patients on mechanical ventilation in the ICU meeting the eligibility criteria shall undergo a daily screen for weaning readiness. If any of the components of the daily screen is not met, the patient will not undergo a SBT that day and continued to be screened daily. Patients passing daily screening criteria shall automatically receive an SBT. The SBT shall last for 30-120 minutes and be performed on continuous positive airway pressure up to 5 cm H2O and pressure support up to 7 cm H2O. The SBT shall be terminated, and mechanical ventilation reinstituted at the original settings if the patient meets any of the SBT failure criteria. A trial is considered successful, and physicians will be asked to approve extubation when the patient can breathe spontaneously for the whole trial. As part of the clinical investigation, patients shall be continued to be screened daily until extubation, 21 days after enrollment, the performance of tracheostomy, death, or withdrawal of care. All patients shall be followed until hospital discharge or death.
Detection and relief of dyspnea in mechanically ventilated patients is a priority. Optimization of mechanical ventilation settings is unfortunately often insufficient to relieve dyspnea in patients entering the weaning process. Pharmacological treatments are effective but their use is likely to delay separation with the ventilator. Promoting the development of non-pharmacological interventions is therefore an interesting avenue. The hypothesis is that the application of high-flow humidified nasal air in orotracheally intubated patients can decrease the work of breathing and relieve dyspnea at the time of weaning from mechanical ventilation. Patients will be exposed to stepwise increase in high flow nasal air (0 L/min, 30 L/min, 50 L/min and 70 L/min) before to undergo a 60 minutes spontaneous breathing trial. During the protocol, dyspnea, inspiratory effort, respiratory drive, respiratory muscles electromyogram (EMG) and patient's comfort will be assessed.
Awake prone positioning has been used widely for patients with COVID-19.Many research results are not uniform on the key issue of whether the prognosis of patients can be improved，and most of the subjects were patients with SARS-CoV-2 infected who are not intubated.The investigators will conduct a prospective observational study on patients with acute respiratory failure induced by various causes to determine whether awake prone position can reduce the need to upgrade to invasive mechanical ventilation and improve the prognosis of patients compared with standard treatment.
With this interventional prospective study, we aim at comparing the effectiveness of Neural Pressure Support (NPS) in reducing respiratory work and patient-ventilator asynchronies as compared with standard Pressure Support Ventilation (PSV), in a cohort of patients with Acute Respiratory Failure (ARF) and low respiratory system compliance.
Landmark trials in critical care have demonstrated that, among critically ill adults receiving invasive mechanical ventilation, the use of low tidal volumes and low airway pressures prevents lung injury and improves patient outcomes. Limited evidence, however, informs the best method of mechanical ventilation to achieve these targets. To provide mechanical ventilation, clinicians must choose between modes of ventilation that directly control tidal volumes ("volume control"), modes that directly control the inspiratory airway pressure ("pressure control"), and modes that are hybrids ("adaptive pressure control"). Whether the choice of the mode used to target low tidal volumes and low inspiratory plateau pressures affects clinical outcomes for critically ill adults receiving mechanical ventilation is unknown. All three modes of mechanical ventilation are commonly used in clinical practice. A large, multicenter randomized trial comparing available modes of mechanical ventilation is needed to understand the effect of each mode on clinical outcomes. The investigators propose a 9-month cluster-randomized cluster-crossover pilot trial evaluating the feasibility of comparing three modes (volume control, pressure control, and adaptive pressure control) for mechanically ventilated ICU patients with regard to the outcome of days alive and free of invasive mechanical ventilation.
