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

Patients with acute brain injury often require invasive mechanical ventilation connection, increasing the risk of developing complications such as respiratory secretions retention. Thethoracic compression is a manual chest physiotherapy technique that can improve clearance of secretions in these patients. Although today the scientific evidence is contradictory, the manual abdomino-thoracic compression may be associated with increased intracranial pressure in patients with acute brain injury.

Objectives: The aim of this work to study the effects of manual thoracic compression technique in intracranial pressure in mechanically ventilated patients. Furthermore, the effects of the technique in different volumes and flows recorded by the ventilator and the relationship between the pressure applied in the intervention group and the different variables will also be studied.

Methodology: It will be a randomized clinical trial, single-blind in the application of the techniques. Patients with acute brain injury in invasive mechanical ventilation will be included, randomized into two groups. In the control group, a technique of passive inferior limbs mobilization will be applied and in the intervention group it will be performed the manual thoracic compression technique. The data of the primary variable, intracranial pressure will be collected with a monitoring system and continuous recording (Integra Camino).

A descriptive analysis of the values collected from the variables in the study will be performed, studying the measures of central tendency. In the presence of normal distribution will be presented mean and standard deviation, and median and interquartile range in case of non-observation of normal distribution. The normality of the samples will be verified with the Kolmogorov-Smirnov test. The verification of the hypothesis in study will be assessed using the Student T test for independent samples in case of sample normality and by the Wilcoxon test otherwise. A multiple linear regression analysis will be performed: considering as a dependent variable the differences in intracranial pressure, difference or volume / minute gain and expiratory flow and between the covariates, the type of technique, the pressure applied in the technique under study, the type of brain injury, age, sex, etc.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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
intracranial pressure changes
Time Frame: 5 minutes before start procedure, immediately after procedure, 5 minutes after the end of procedure and 10 minutes after the end of procedure
with Camino ICP monitoring
5 minutes before start procedure, immediately after procedure, 5 minutes after the end of procedure and 10 minutes after the end of procedure

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
oxygen saturation changes
Time Frame: 5 minutes before start procedure, immediately after procedure, 5 minutes after the end of procedure and 10 minutes after the end of procedure

peak expiratory flow changes
Time Frame: all the respiratory cycles will be recorded 30 seconds before procedure and during the procedure
with maquet servo u and servo i ventilators, the purpose is to identify the best peak expiratory flow before and during the procedure, and to compare them.
