Post-Resuscitation Pneumothorax - Analysis of Incidence, Risk Factors and Outcome Relevance

December 13, 2023 updated by: Auinger, Daniel MD

Pneumothorax After Cardiopulmonary Resuscitation Following Out-of-Hospital Cardiac Arrest - Analysis of Incidence, Risk Factors and Impact on Outcome

In this retrospective study, the investigators seek to investigate the incidence of pneumothorax following possible risk factors, and elucidate its association with outcomes.

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

This is a retrospective analysis of routine data, collected by a single Emergency Medical System (EMS). Adult patients (≥18 years) hospitalised after Out-of-Hospital Cardiac Arrest (OHCA) who received chest compressions and underwent chest imaging within 12 hours after hospital admission were included.

Variables and outcomes ascertained are built up of the core elements of the latest version of the Utstein Resuscitation Registry Template for OHCA. This includes sex, age, aetiology of arrest, response times of the first emergency medical service team and emergency physician, witnessed cardiac arrest, bystander CPR/AED, arrest location, first monitored rhythm, defibrillation time, drugs given, reperfusion attempted and target temperature management. Additional variables studied were pre-existing health status represented by the Pre Emergency Status Assessment (PESA), history of lung disease, no-flow-time (time from collapse until initiation of CPR), use of a mechanical chest compression device and prehospital CPR duration.

The primary outcome is incidence of pneumothorax, secondary outcomes are survival to hospital discharge and favourable neurological condition at hospital discharge defined by a cerebral performance category (CPC) of 1 or 2.

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

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.

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
Time Frame
Presence of pneumothorax
Time Frame: within 12 hours of admission
within 12 hours of admission

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
Time Frame
Survival
Time Frame: to hospital discharge (up to 2 months)
to hospital discharge (up to 2 months)
Cerebral Performance Category
Time Frame: at hospital discharge (up to 2 months)
at hospital discharge (up to 2 months)

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

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.
February 2, 2020

Primary Completion (Actual)

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.
October 20, 2022

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
