Filter by:The aim is to describe the incidence, characteristics, risk factors and outcome of complications acquired under mechanical ventilation (called ventilator-associated events) according to the new CDC criteria, in a population of patients admitted in intensive care unit after cardiac arrest.
One challenge with decision making for mechanically ventilated is that their prognosis is often uncertain. The ProVent-14 score incorporates clinical variables measured on the 14th day of mechanical ventilation to predict risk of death in one year. The ProVent-14 is easy to calculate has been externally validated. However, it is unclear how often clinicians use the ProVent-14 score to predict long-term outcomes for patients requiring 14 days of mechanical ventilation or if it helps clinicians make more accurate predictions. The purpose of this study is to determine whether ICU clinicians who receive a patient's ProVent-14 score make more accurate predictions for mortality at one year than ICU clinicians who do not.
"Weaning from mechanical ventilation is a crucial step in the intensive care unit. Several factors complicate weaning and increase the risk of failure. To predict the success of extubation, the spontaneous ventilation test (T-Tube) remains essential. Despite this, the failure rate is around 10-20%. Failed extubation is not without consequences, since it increases the risk of pneumopathy and mortality. It therefore seems essential to identify potential extubation failures using effective predictive criteria. Several of these predictive criteria have been studied separately in the literature, but are still not widely used in practice. Many studies have sought to identify these predictive criteria, without actually linking them. However, when combined in a single assessment prior to extubation, they could represent a reliable prediction and decision-making aid. In the intensive care unit at Hôpital Bichat Claude Bernard, a team of physiotherapists dedicated solely to this unit carries out a routine EPIC Assessment, combining several criteria, some of which have individually demonstrated their reliability in predicting extubation outcome. Physiotherapists are health professionals working as part of the intensive care team, and are well versed in issues relating to bronchial congestion, respiratory function and muscle strength, whether for breathing or locomotion. Similarly, their involvement in issues relating to swallowing disorders acquired in intensive care gives them an overall view of the patient's ability to protect his or her airway post-extubation. The EPIC Assessment has been designed by them to address these issues. With the help of this assessment, and by following the cut-offs of the various criteria, they link the different criteria making up the EPIC Assessment and communicate a ""favorable"" or ""unfavorable"" opinion for extubation. Our hypothesis is that the EPIC Assessment is, in addition to its interpretation by physiotherapists, a reliable tool for predicting the outcome of extubation."
The goal of this clinical trial is to learn if oxycodone hydrochloride works to manage pain in patients requiring mechanical ventilation. It will also assess the safety of oxycodone hydrochloride. The main questions it aims to answer are: 1. Does oxycodone hydrochloride effectively lower the CPOT (Critical Care Pain Observation Tool) score in mechanically ventilated patients? 2. What medical problems do participants have when using oxycodone hydrochloride? Researchers will compare oxycodone hydrochloride to remifentanil to see if oxycodone works better to manage pain in these patients. Participants will: - Receive either oxycodone hydrochloride injection at a dose of 0.03-0.2 mg/kg/h or remifentanil injection at a dose of 2-9 μg/kg/h. - Have their pain scores assessed every 15 minutes until the CPOT score is less than 3. After reaching the target pain score, assessments will be done every 4 hours. - Have their vital signs and monitoring data recorded. - Have analgesia and sedation scores recorded from days 1 to 7 after administration, with drug dosages adjusted based on pain scores. - Have the incidence of adverse reactions and changes in gastrointestinal function observed and recorded from days 1 to 7 after administration. - If extubated within 7 days, relevant data will be collected based on the time of extubation. - Be followed up on day 28 through the electronic medical record system to gather data on the extubation success rate and incidence of complications within the 28-day period.
The goal of this physiological intervention study is to unravel the (patho)physiological mechanisms and potential clinical benefits of a pre-specified early switch from controlled to assisted ventilation in mechanically ventilated adult patients with acute hypoxemic respiratory failure (PaO2/FiO2 ratio < 200 mmHg). The intervention is that participants will be switched from controlled to assisted ventilation when PaO2/FiO2 ratio > 200 mmHg. The primary endpoint is the change in regional lung stress (as derived by electrical impedance tomography) when switching from controlled to assisted ventilation and until a successful or failed switch.
This observational study will explore the effects of PEEP and position on regional lung ventilation-perfusion mismatch by electrical impedance tomography (EIT) in moderate-to-severe ARDS patients with different lung recruitability.
In patients who are mechanically ventilated for more than 72 hours weaning failure is a common issue. The Spontaneous breathing trial (SBT) is often done to assess if the patient can be extubated with a high chance of success. However, re-intubation rates are between 15 - 20 % after a successful SBT. The rapid shallow breathing index (RSBI) is an important parameter used in an SBT. Because the high incidence of extubation failure (re-intubation within 48 hours) a search for a better parameter than the RSBI is warranted. Using the measured end-tidal oxygen (etO2) of mechanically ventilated patients it is possible to calculate the VO2, which is a measure of patient effort. The VO2 is a parameter with the potential to predict weaning success or failure, together with other parameters of patient effort like the work of breathing (WOB), pressure time product (PTP) and esophageal pressure swings, reflecting muscle strength of the diaphragm. Therefore, the investigators want to investigate if these parameters are associated with an SBT success or failure.
Sedatives and analgesics are usually given for analgesic, anxiolytic, or sedating purposes for patients with critical illness, while they inevitably inhibit respiratory and circulatory function. Sometimes, patients receive deep sedation to induce hypoventilation or suppress spontaneous respiratory effort. The sedation level in clinical practice is usually assessed with subjective sedation scoring systems, such as the Richmond Agitation Sedation Scale (RASS). However, studies have found that sedation depth based on RASS is not a reliable marker of respiratory drive during critical illness. In recent years, researchers have proposed to monitor the effects of sedatives and analgesics on respiratory indicators and to implement lung-protective sedation, such as P0.1, Pocc, Pmus, WOB, and PTP. However, different pharmacological characteristics, different depths of sedation, and different sedation regimens among different sedatives and analgesics make a great difference in their effects on respiration. Ciprofol is an analog of propofol, with increased stereoselective effects adding to its anesthetic properties, is increasingly used in the intensive care unit, but its effects on respiration are not well understood. Therefore, this study aims to investigate the effects of ciprofol on respiratory patterns, respiratory drive, and inspiratory effort in mechanically ventilated patients.
this study is to assess the hemodynamic profile of ketamine compared with propofol in critically ill, mechanically ventilated adult Patients study will be carried out on 100 mechanically ventilated patients who received one sedative agent propofol or ketamine The patients will be randomized into two equal groups to receive either ketamine or propofol Group 1 (Ketamine group): ketamine is initiated at 0.5 mg/kg/h and titrated by 0.25 mg/kg/h every 15 minutes to a maximum dosage of 4 mg/kg/h to achieve appropriate sedation. Group 2 (Propofol group): Propofol is initiated at 0.3 to 0.6 mg /kg/hr. and titrated by 0.3 to 0.6 mg/kg/h every 5 to 10 minutes up to a maximum dosage of 4.5 to 4.8 mg/kg/hr. to achieve appropriate sedation.
The goal of this randomized clinical cross-over trial is to compare power dissipation (Pd) during flow-controlled ventilation with either standard of low tidal volume ventilation or compliance guided individualization of ventilator settings. This study is performed in patients scheduled for open abdominal surgery and the primary and secondary outcome parameters are: - power dissipation [J/min] during ventilation calculated by integrating the hysteresis of the tracheal pressure-volume loop - applied mechanical power during ventilation calculated by published formulas [1] - oxygenation of the blood assessed by PaO2/FiO2 ratio - decarboxylation assessed by required respiratory minute volume to maintain normocapnia - comparison of respiratory variables in low tidal volume versus individualized ventilation Participants will randomly receive either low tidal volume (LTV) or individualized flow-controlled ventilation [2]. In the LTV group, the positive end-expiratory pressure will be set to 5 cmH2O and the peak pressure set to achieve a tidal volume of 7 ml/kg predicted body weight. In the individualized group positive end-expiratory and peak pressure will be titrated to achieve the highest compliance [2]. In both groups the flow will be set to achieve normocapnia (PaCO2 35-45 mmHg). After obtaining three consecutive measurements the ventilation strategy will be switched to the alternative regime in a cross-over design and again, three measurements recorded. The investigators hypothesize, that individualized ventilator settings are able to improve ventilation efficiency in terms of a lower required minute volume to maintain normocapnia and thus is able to reduce power dissipation during ventilation. Secondary endpoint will be a comparison of Pd to calculated mechanical power, as a currently accepted surrogate parameter for ventilation invasiveness [2] and also outcome predictor. Additionally, gas exchange parameters such as oxygenation and decarboxylation will be compared between low tidal volume and individualized ventilation.
