Asynchronies During Mechanical Ventilation

Asynchronies During Mechanical Ventilation: Factors Related

Invasive mechanical ventilation (IMV) is a life support treatment for patients with acute respiratory failure. The IMV can generate adverse effects that may cause alterations in other organs besides the lung, creating an important problem during ICU stay, hospital stay and years after discharge. These consequences on morbidity and mortality have significant economic and social weight. In the United States the IMV represents 2.7 episodes per 1000 habitants, with an estimated cost of $27,000 million, representing 12% of all hospital expenses. The overall mortality in patients with IMV is 30-35%, increasing with age. Therefore, patients receiving IMV are a high-risk population and with higher costs.

A poor interaction between patient and ventilator during IMV can develop asynchronies. The asynchronies may present in 25% of patients. The majority of studies in ICU patients are limited to a evaluation of short periods of time. Asynchronies identification needs the application of respiratory physiology knowledge and the interpretation of respiratory signals from the ventilator waves. This allows identifying in an easy way different situations of "fight", but it also difficult the identification of situation where asynchronies are less obvious, doing that them remain underdiagnosed. Moreover, asynchronies can be only evaluated during a brief period of time, and it's difficult to know their incidence during all the IMV period and to make adjustments to improve them.

In our centre, it has been developed a continuous monitoring system during IMV which integrates, in real-time, all the information derived from digital monitors and ventilators. It allows a continuous and automatic detection of different events (through an intelligent alarm system) and quantification of asynchronies. It was demonstrated that asynchronies are frequent, that it can be present from the beginning of IMV, that it increase in severe patients under deep sedation and it can increase ICU and hospital mortality.

The investigators can study different factors that can influence over asynchronies development or can improve them.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The aim of this study is to analyze the real incidence of asynchronies of patients undergoing mechanical ventilation and to analyze what factors may have an association with their appearance.

This factors includes factors related with the pulmonary mechanics of each patient and other factors such as the treatment administered, especially drugs with sedative and analgesic effect will be taken into account.

This can help to implement strategies for the improvement of asynchronies.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence of asynchronies during mechanical ventilation
Time Frame: during all period of mechanical ventilation up to the study end, approximately december 2018
Data will be collected through the middleware Better Care, an automatic system of asynchronies detection
during all period of mechanical ventilation up to the study end, approximately december 2018

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Influence of sedation and analgesia in the incidence of asynchronies
Time Frame: during all period of mechanical ventilation up to the study end, approximately december 2018
