The Effect of Percutaneous Dilatational Tracheostomy on Intracranial Pressure

January 15, 2025 updated by: Melike Cengiz, Akdeniz University

The Effect of Percutaneous Dilatational Tracheostomy on Intracranial Pressure: a Prospective Observational Study

Percutaneous dilatational tracheostomy (PDT) is a common bedside alternative to surgical tracheostomy in intensive care unit patients. Intracranial pressure measurement is a vital parameter that should be monitored when performing any procedure including PDT in these patients. During PDT, changes in intracranial pressure may occur depending on the position applied, hypercarbia and hypertension that may develop during the procedure. However, the effect of PDT procedure on intracranial pressure is controversial. It is imperative to ascertain the impact of PDT on intracranial pressure, along with the factors that influence its fluctuations during the procedure. This is of particular significance in order to avert the occurrence of deleterious conditions that may be engendered by elevated intracranial pressure. The aim of current study was to evaluate the effect of PDT procedure on intracranial pressure.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

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

Since the study is a prospective observational study, the investigators will not be the decision-making physicians about the treatments applied to the patients. The optic nerve sheath diameter measurement method by ultrasonography will be used to determine intracranial pressure.Intracranial pressure measurement will be performed in neutral position before PDT, after the patient is positioned for the procedure, immediately after the procedure and immediately after the patient is placed in neutral position. Demographic characteristics, comorbidity status, PDT indication, intensive care unit hospitalisation diagnosis, intracranial pathology data, haemodynamic data, arterial blood gas parameters will be recorded.

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.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Patients over the age of 18 who were decided to open percutaneous dilatational tracheostomy for various reasons will be included in the study.

Description

Inclusion Criteria:

  • Clinical indication for PDT

Exclusion Criteria:

  • Age <18
  • Patients with glaucoma
  • Patients with optic nerve damage
  • Patients in whom PDT is contraindicated (coagulopathy, infection at the site of intervention, etc.)

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
Effect of PDT procedure on intracranial pressure
Time Frame: 6 months
The primary outcome of this study was to evaluate the impact of bedside PDT on intracranial pressure through ultrasonography-guided measurement of the optic nerve sheath diameter.
6 months

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
The effect of presence/absence of intracranial pathology on intracranial pressure change during PDT procedure
Time Frame: 6 months
The secondary outcome of this study was to evaluate the effect of the presence/absence of intracranial pathology on intracranial pressure change during bedside PDT procedure by ultrasonography-guided optic nerve sheath diameter measurement.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
August 1, 2024

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
