April 23, 2026 updated by: Ling Liu, Southeast University, China

Effect of Neurally-Adjusted Ventilatory Assist (NAVA) on Weaning Outcome in Patients With Mechanical Ventilation: Multicenter, Single-blind, Parallel, Control, Randomized Clinical Trials

This study intends to compare the effects of NAVA and PSV on weaning success rate and mechanical ventilation time in patients with tracheotomy patients through a randomized controlled study.

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

For patients with difficult weaning, NAVA can shorten the time of mechanical ventilation, but there is no large-scale study to explore the effect of NAVA on the weaning success rate and mechanical ventilation time of patients with gas resection. Therefore, this study intends to compare the effects of NAVA and PSV on weaning success rate and mechanical ventilation time in patients with tracheotomy patients through a randomized controlled study.

It is a prospective, multicenter, parallel group, single blind, randomized controlled tria。

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.
