Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 19 to 95 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: The written consent forms are obtained from all the subjects who agreed to participate in the study. Patients who suffered Covid-19 prior to surgery without previous moderate-severe pulmonary pathology, that at the time of surgery present negative PCR and absence of clinic due to SARS-CoV-2, are included in the Post-COVID 19 group. The "control group" includes patients over the age of 18 who did not have COVID-19 and without moderate-severe pulmonary pathology prior to surgery.

Who may be able to join

  • -Patients over the age of 18 who did not have COVID-19 and who are going to undergo scheduled surgery

Who cannot join

  • Patients under the age of 18.
  • Unstable patients in shock
  • Patients in current state of pulmonary hypertension or heart failure
  • Patients with moderate-severe pulmonary pathology prior to surgery.
  • Patients previously surgery for chest surgery
  • Patients in current state of respiratory infection

About this study

Official title: Post-COVID 19 Patients Undergoing Surgery: Determination of Residual Lung Abnormalities and Postoperative Adverse Effects

More and more patients are undergoing elective surgery after SARS-CoV-2 infection, and little is known about the residual pulmonary changes in these patients after infection and postoperative pulmonary complications. So, we propose an observational study comparing postCOVID-19 patients with normal population (control group) undergoing surgery.

Read the detailed description

The most common lung complications of severe COVID-19 are pneumonia and hypoxemic respiratory failure/ARDS. Manifestations of lung inflammation or fibrosis were also observed in late stages of COVID-19 causing respiratory sequelae. Fibrous lesions may form during the healing of pulmonary chronic inflammation or proliferative diseases, with gradual replacement of cellular components by scar tissues indicating a poor outcome of COVID-19. Ultrasound allows to stratify the severity of lung damage and combined with the clinic, can help estimate the patient's prognosis and support therapeutic decision-making. On the other hand, pulmonary inflammatory processes and fibrosis are responsible for a decrease in respiratory distensibility or pulmonary compliance. Pulmonary parenchyma distensibility is known as static distensibility or compliance and it´s calculated by mechanical ventilators during general anesthesia.

There are no studies that determine the results of lung ultrasound and pulmonary compliance in preoperative and intraoperative period respectively in postCOVID patients, and the postoperative complications of postCOVID patients are poorly understood.

Study groups in NCT04922931
Study groupRoleWhat they receive
Post-COVID-19 groupThe Post-COVID-19 group or case group includes post-COVID patients (confirmed by PCR) >18 years undergoing scheduled surgery without pulmonary disease prior to SARS-CoV-2 infection that at the time of surgery present negative PCR and absence of clinic due to SARS-CoV-2.
Receives: Procedure: scheduled surgery
Control groupThe control group includes patients over the age of 18 who did not have COVID-19 and without moderate-severe pulmonary pathology prior to surgery and in conditions of hemodynamic and respiratory stability at time of surgery.
Receives: Procedure: scheduled surgery

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Determination of residual pulmonary alterations in post-COVID patients

    1. Determination of residual pulmonary alterations using preoperative lung ultrasound and obtaining intraoperative compliance in postCOVID-19 patients undergoing surgery.

    Measured: 1 month

  2. Correlation between lung ultrasound and pulmonary compliance

    Analyze the correlation between the values obtained with pulmonary ultrasound and the pulmonary compliance obtained by mechanical ventilation in patients with general anesthesia.

    Measured: 1 month

Secondary outcomes (1)
  1. postoperative complications

    Determine postoperative complications one month after surgery.

    Measured: 1 month

Questions about this trial

What is this clinical trial studying?

An observational study of Covid19, run by Hospital Universitari Vall d'Hebron Research Institute at 1 site in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Sep 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Determination of residual pulmonary alterations in post-COVID patients (time frame: 1 month). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04922931, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Sep 2021.
