NCT ID: NCT06009731 Recruiting - Clinical trials for Mechanical Ventilation

Diaphragmatic Speckle Tracking During Spontaneous Breathing Trial

DIAST
Start date: June 12, 2023
Phase:
Study type: Observational

Currently, measurement of transdiaphragmatic pressure (Pdi) using oesophageal and gastric balloons is the gold standard for the assessment of diaphragmatic effort. This technique is relatively invasive and its interpretation may be complex. The diaphragmatic longitudinal strain (LSdi) and strain rate (LSRdi) might provide additional information in the assessment of diaphragmatic effort and movement during SBT, allowing early detection of diaphragmatic dysfunction. Patients will be monitored during a 30-120 minutes SBT consisting of no assistance on the ventilator using CPAP with a pressure level of 0 cmH2O. Parameters to evaluate diaphragm function will include diaphragmatic strain (LSdi and LSRdi), diaphragmatic thickening fraction (TFdi), and airway occlusion pressure (ΔP0.1 and ΔPocc). These parameters will be measured immediately before ('baseline') the SBT, as well as 2 minutes ('early' assessment), 15 ('intermediate' assessment) and 30 minutes ('late' assessment) after the beginning of the SBT.

Effect of a Personalized Weaning Strategy on Weaning Success

P-Wean
Start date: March 14, 2023
Phase: N/A
Study type: Interventional

Weaning from mechanical ventilation is a daily challenge in intensive care units, as it can take up to 50% of the total duration of ventilation. The longer the duration of ventilation is, the more there is complication related with it. Even when the spontaneous breathing trial is succeeded, 10 to 20% of extubations are failed and requires re-intubation. There is two different ways to assess if the patient is capable of breathing by its own : T-piece which can be considered as hard to succeed (it can delay extubation for some patients) or pressure support ventilation with no PEEP which can be too easy and lead to an extubation too early. Studies have identified risk factors of weaning induced pulmonary oedema wich is one of the main cause of failed extubation (up to 60%). The purpose of P-WEAN is to evaluate whether a personalized strategy for weaning from mechanical ventilation, including daily search for weaning criteria and individualization of the weaning modality (T-piece or pressure support ventilation with zero PEEP) based on the existence of WIPO risk factors (obesity, COPD, cardiopathy) improves weaning success compared with usual practice.

Prediction Of Pulmonary Edema With Müller Maneuver

PoEM
Start date: May 9, 2022
Phase: N/A
Study type: Interventional

The mechanical ventilation weaning must begin as early as possible to limit its complications and requires a spontaneous breathing trial (SBT) before the separation from the ventilator to the patient. However, some patients fail this test and cannot be extubated. The main causes are pulmonary edema and diaphragmatic dysfunction. Predicting the risk of failure before carrying out the SBT makes it possible to anticipate a failure of the extubation and to adapt the therapies as well as possible. To assess the risk of pulmonary edema, cardiac preload, which corresponds to the end-diastolic filling volume of the ventricle, can be estimated using simple tests as the passive leg raising test before an SBT. However, this test requires tilting the patient's trunk and raising the lower limbs to 45°, and is not practical, especially in intensive care. The Müller maneuver, which allows maximum inspiratory pressure measurement via a one-way valve connected to the intubation tube, is currently used in routine care for diaphragmatic assessment. The endothoracic depression induced by this test is likely increasing venous return and cardiac output in patients with a reserve of preload, i.e. in preload-dependent patients. This test would be an easy alternative to the passive leg raising test used in current practice. The objectif is to assess whether the presence of an independant prelaod state, as detected by the absence of increased cardiac output during the Müller maneuver, is associated with the occurence of pulmonary edema during weaning from mechanical ventilation. The study consist in the measurement of cardiac output before and after the passive leg raising test and the Müller maneuver, then measurement of cardiac output before and after an SBT. A transthoracic ultrasound and a blood sample with dosage of proteins and hemoglobin will be carried out initially and then at the end of the SBT as part of routine care. The investigators hypothesize: - The Müller maneuver induces a greater increase in cardiac output in patients in a state of preload dependancy than in patients in a state of preload independancy. - The absence of documented preload dependancy during a Müller maneuver is associated with the occurrence of pulmonary edema during an SBT. The investigators included patients : - > 18 years old, conscious patient, with health insurance, placed under mechanical ventilation for at least 24 hours ; - In whom it was decided to perform a passive leg raising test and an SBT. The investigators excluded pregnancy, patient with chest tube, particpation in another interventional study, tracheostomy, patient under legal protection.

NCT ID: NCT05297357 Completed - Weaning Clinical Trials

Complementary Weaning With Adult Food Typical of the Mediterranean Diet

Start date: May 1, 2015
Phase: N/A
Study type: Interventional

A Randomized Controlled Clinical Trials was conducted to study the medium-long term impact of a complementary weaning using adult foods typical of Mediterranean Diets (MD) on children taste development and eating habits, and on the microbiota composition. Main objectives were to assess the effect of such weaning scheme on: 1. medium-long term adherence of the children to the MD (Primary aim). 2. familial eating habits to verify how many changes may come from an early education of the kid toward a Mediterranean eating style 3. the BMI of the children 4. gut microbiota composition

Predictors Of Successful Extubation in Critically Ill Patients: Multicentre Observational Study

POSE
Start date: May 1, 2017
Phase:
Study type: Observational

Extubation failure can directly worsen patient outcomes. Therefore, the decision to extubate is a critical moment during an intensive care unit (ICU) stay. The decision to extubate is usually made after a weaning readiness test involving spontaneous breathing on a T-piece or low levels of ventilatory assistance. However, extubation failure still occurs in 10 to 20% of patients. The investigators focused on previously reported physiological risk factors, and were able to obtain from common clinical practice: 1) age, 2) underlying cardiovascular disease, 3) underlying respiratory disease or occurrence of pneumonia, 4) rapid shallow breathing index (RSBI), 5) positive fluid balance during the previous 24 hours, 6) the ratio of arterial oxygen partial pressure to fractional inspired oxygen, 7) Glasgow Coma Scale, 8) respiratory tract secretions. The investigators aimed to assess the incidence and risk factors for extubation failure among critically ill patients who passed the 30 min spontaneous breathing test (SBT) using a low level of pressure support (PS) with positive end-expiratory pressure (PEEP), in a prospective multicenter study.
